Black Hole Computer Simulations Help to Identify Third Gravitational Wave

Gravitational Wave Signal

Significant contributions to gravitational wave astronomy continues with Rochester Institute of Technology researchers with the third detection of gravitational waves as well as a fresh black hole which is 49 time the size of the sun. The results from the detection of gravitational waves on January 4, was recently announced by the LIGO collaboration and the finding would be published in the journal Physical Review Letters.

 RIT scientists had supported the collaboration measure as well as interpreted black hole spins together with their alignment. These measurements could tell scientists on what occurred when massive stars tend to die and transform into black holes. The gravitational wave signal had been developed from the collision of black holes. The freshly located black hole which had been formed by the merger had a mass of around 49 times that of the sun.

This tends to fill in a breach between the masses of the two merged black holes detected earlier by LIGO, with that of the solar masses of 62 – the first detection and 21 – second detection. Richard O’Shaughnessy, associate professor in RIT’s School of Mathematical Sciences had commented that they can see the outlines of a population of black holes emerge.

Combination of Heavy Black Holes – Plenty of Net-Aligned Spin

The LIGO paper quotes O’Shaughnessy’s upcoming research that had been utilised in part to assist in interpreting the latest event. He had presented his work at the American Astronomical Society in Austin, Texas. He noted that the fresh observations rule excludes the possibility that combination of heavy black holes tend to have plenty of net-aligned spin and are in agreement with the breakthrough observation of 2015 of LIGO.

O’Shaughnessy stated that either since heavy black hole spins seems to be small or due to they being tilted, their net effect cancels out. Various teams have made diverse predictions for black hole spins and the most extreme forecasts are ruled out. With regards to the others, it is only a matter of time. Centre for Computational Relativity and Gravitation, a research at RIT is developing the techniques for comprehending the crucial astrophysical parameter spin according to Professor Carlos Lusto, in the School of Mathematical Science of RIT.

 Lousto had commented that at RIT, they are working on enhancing the spin measurements of the black holes by resolving to high precision the equations of Einstein and directly comparing those theoretical forecasts with those of the observed signals of LIGO.

Gravitational Ways Moves at Speed of Light

At the Centre for Computational Relativity and Gravitational of RIT, researchers have openly linked the wave signals to their computer simulations considering the equations of Albert Einstein. The latest interpretations have further tested the general theory of relativity and prediction of Einstein that gravitational ways tends to move always at the speed of light.

 No confirmation has been seen by LIGO that the waves had travelled at different speeds. According to Manuela Campanelli, director of the Centre for Computational Relativity and Gravitation and Frontier in Gravitational Astrophysics, which is an RIT signature research area, this third event is in a mass range intermediate to the earlier two events showing that the black hole mergers are common in the universe.

The members of the RIT of the LIGO Scientific Collaboration comprise of John Bero, Hans-Peter Bischof, Manuela Campanelli, James Healy, Brennan Ireland, Jacob Lange, Carolos Lusto, Rupal Mittal, Richard O’Shaughnessy, Monica Rizzo, Nicole Rosato, John Whelan, Andrew Williamson, Jared Wofford, Daniel Wysocki, and Yuanhao Zhang together with Yosef Zlochower.

The international collaboration tends to have around 1,000 members who seem to perform the research of LIGO along with the European-based Virgo Collaboration. The new discovery had taken place at the time of the prevailing observing run of LIGO that had started on November 30 2016 and would be continuing through the summer.

Interpretations of LIGO – Twin Detectors

The interpretations of LIGO had been carried out by twin detectors, one in Hanford, Wash while the other was in Livingston, La. It was operated by Caltech and Massachusetts Institute of Technology with subsidy from the National Science Foundation. The first undeviating surveillance of gravitational waves by LIGO was done in September 2015 while the second discovery was in December 2015.

The LIGO breakthrough paper obviously quotes 2005 landmark research done by Campanelli together with her team on binary black hole mergers and considering this milestone work, Lusto together with Healy statistically revealed the merger of a pair of black holes with replicated gravitational waveforms which seemed to match the first detection of LIGO.

Subsidized by the National Science Foundation, LIGO was operated by MIT and Caltech, conceived and the project was constructed. Monetary support for the Advanced LIGO project had been led by NSF with Germany – Max Planck Society, the U.K. – Science and Technology Facilities Council and Australia – Australian Research Council which made substantial commitments as well as contributions to the project.

Over 1,000 scientists from across the globe had participated in the work through the LIGO Scientific Collaboration that comprised of the GEO Collaboration. The partners of LIGO with the Virgo Collaboration which is a consortium comprising of 280 additional scientists all over Europe had been supported by the Centre National de la Recherche Scientifique, the Istituto Nazionale di Fisica Nucleare and Nikhef and Virgo’s host institution, the European Gravitational Observatory.

Leaked footage from top-secret Area 51 military base shows mysterious ALIEN craft


Area 51 – Base for Alien Spacecraft & Technology

Area 51 is said to be one of the secretive areas in the world and according to the author of the UFO Investigations Manual, Nigel Watson who informed MailOnline, Area 51 is said to be a magnet for those who are of the belief that the US Government knows a lot more about UFOs than they seem to reveal to the public. People like the late Boyd Bushman, a senior scientist who had worked for Lockheed Martin had declared that the Area 51 is a base where alien spacecraft and technology is stored and examined.

UFO hunters at Secure Team 10 have now exposed leaked footage which portrayed an unfamiliar craft hiding in the Nevada-based military facility. The peculiar video tends to portray a flying object soaring in the sky and later flying away, releasing a strange light while occasionally moving from side to side. Tyler Glockner running the SecureTeam 10 on the YouTube clip has commented that it is one of the mysterious pieces in UFOlogy. He has described the footage as a hidden gem which is said to be filmed in the 1980s or 1990s. The mysterious object seemed to be getting higher and higher releasing a peculiar light as per the footage.

Hot Spot for Alien Fanatics

However unconvinced ufologist Scott Brando running hoax busting website ufoofinterest.org had stated that the video had not been recorded at Area 51 but another top-secret USAF base in Nevada had been recorded. On May 30, 1995, Mr Brando had shown the same footage that had been recorded at the Nellis Air Force base in Las Vegas. He frequently highlights Secureteam 10 for confusing its over 750,000 subscribers. He together with other UFO hoax busters have claimed to have revealed its use of CGI footage and misrepresentation and the channel seems to be on the blacklist on a numb UFO website.

Mr Glockner has denied being a deliberate hoaxer and had claimed that his research is candid. Since late 1970s, the Nevada based military testing facility is said to be a crucial point of several conspiracy theorist as well as UFOlogists who have claimed that the base houses enigmatic alien technology. The extensive military complex is placed between a dry lake bed towards the North East and a small mountain to its West. Since 2013, area 51 has been a hot spot for alien fanatics since the government had not acknowledged it existence.

Historic Test Site for Military Aircraft

The same has remained enclosed from prying eyes of the public with guards equipped with weapons guarding the surrounding area. Statements of alien conspiracies near Area 51 have been largely exposed though the site has been confirmed as a historic test site for military aircraft.

Some of the well-known machines have been developed there comprising of the U-2 spy plane, SR-71 Blackbird and the F-117A Nighthawk stealth fighter. Area 51 is covered by a severe 23 by 25 mile, no-fly zone for civilian aircraft. Neighbouring viewpoints Freedom Ridge and White slides Peak providing vantage points watching down on the base are said to be prohibited to the public.

Chapatti Movement

The Revolution of 1857 – Chapatti Movement 

 

History is said to be of several lessons and tends to have great mysteries for us to unravel. Some may tend to be new while others could be very ancient. One such mystery is regarding the Chapatti Movement which involved the rare distribution of thousands of chapattis which is known to be a kind of unleavened flatbread that was eaten in various Indian villages during 1857. The revolution of 1857 was said to be the first war of independence of India from the British rule.

Though the Indian soldiers were not well equipped as the British soldiers, they fought bravely with all their might laying their lives down fighting the oppression of the British policies. Some historians were of the belief that few months before the revolution of 1857, a mysterious distribution of chapattis had started which was difficult to explain by anyone and the event has left all perplexed over the years.

The Chapatti Movement involved the rare distribution of thousands of chapattis though the crucial cause of the movement is not clear. However the British agents were of the opinion that the chapattis could have contained some secret messages though investigation carried out showed no such messages.

Strange & Inexplicable Distribution

 

Dr Gilbert Hadow, an army surgeon in the employment of the East India Company, in March 1857, had written the following lines describing the peculiar movement which had taken place in 1857 in a letter to his sister in Britain saying that there was a mysterious affair going on all over India. No one was aware of the meaning of the same.

 Moreover it was unclear where it had originated from by whom or for what reason, whether it was supposed to be linked to any religious ceremony or whether it had to do with some secret society. The Indian papers were full of assumptions to what it meant and was known as the Chapatti Movement.

 Dr Hadow described the 1857 movement of the strange and inexplicable distribution of thousands of chapattis which had been passed from one person to another and from village to village all over the country. During that time, tension in British occupied India, was at its peak and the discontented Indians, tired and sick of the unfair British rule were on the quiet planning a mutiny. That year, in February a strange thing occurred.

Movement Exposed by Magistrate of Town of Mathura 

 

Thousands of unmarked chapattis had been circulated to homes as well as police outposts all over India by runners at night where those who had accepted them would silently make more collections and pass them on.

The movement had been exposed by the magistrate of the town of Mathura, Mark Thornhill, who had engaged in some investigation and discovered that chapattis had been travelling up to a distance of 300 kilometres each night everywhere from Narmada River in the south to the border of Nepal many hundred miles to the north.

 The mysterious distribution of the chapattis led to a belief that something strange was going on. On extensive enquiries on the strange distribution of the same gave rise to several theories though few facts. Moreover since there was no written note or any sign on the chapattis, the British were irate for being incapable of finding any valid reasons for stopping or arresting the chapatti runners who often seemed to be police officials themselves.

Strangely, when the chapatti runners were questioned later on regarding the significance of distributing the same from one home to another, they had been totally ignorant of the purpose of the distribution.

Code Signalling a Call to Rebel 

 

The chapattis had been real and even the runners had not been aware of the purpose of the distribution of the chapattis. The police officials would bake the same, which was two inches each in diameter and distribute them to their colleagues who in turn would make some more and pass them to their associates in the neighbouring villages.

In some unusual documents of the revolution of 1857 it was discovered that the chapattis had travelled far and wide by March 5, 1857, from Avadh and Rohilkhand to Delhi. The British officers were filled with anxiety when they discovered that the chapattis had reached into every police station in the vicinity and around 90,000 policemen had been involved in the movement.

They were particularly disturbed knowing that the chapattis had been moving much quicker than the fastest British mail. Though they had no convincing proof the confused British assumed that the chapattis had been some sort of a code signalling a call to rebel against the colonial rule.

Shaken British Empire to the Core

 

Debates were on as to whether the same had come from the east, near Kolkata or from Avadh in the north or from Indore in the centre of the country. Overall the Chapatti Movement had shaken the British Empire to the core.

 India had been controlled by the British with a small number of men about 100,000 in total, conquering a large population of 250 million and hence they were aware of how insufficient they would be in the event of a serious revolution. Being continuously tensed due to it, they considered any sort of communication by the locals which they were unable to comprehend as suspicious resulting in fear.

Rumours regarding the unusual chapatti chain had resulted in an uneasy atmosphere prevailing across the country. When the rebellion broke out that year, with the first armed rebellion at Meerut on May 10, it had been alleged that due to the circulation of the chapattis, an underground movement had been planned which had started the movement.

Operative Weapon of Psychological Warfare

 

Some years later, J W Sherar, in the book Life During the Indian Mutiny, had acknowledged that if the purpose behind the plan was intended to create an atmosphere of mysterious restlessness its purpose was served. The movement had put the British in a state which turned out to be very operative weapon of psychological warfare against the colonial rule.

Moreover it was said that the chapattis had been a basic in the army of Tantia Tope and Lakshmi Bai when they had moved around at the time of the revolution. The notable guerrilla fighting, Kunwar Singh had also travelled with a few soldiers and would stop at villages in order to get a refill of ghee laden chapattis, gur and water.

Latest studies have shown that the circulation of chapattis could have been an attempt of delivering food to people affected with cholera. But considering the inconclusive evidence, it can only be concluded that at the moment the chapattis had just been chapattis and not any secret messages or warning of looming rebellion.

Quantum Fluctuations Keeps the Universe Swell

Universe

Unsolved Mysteries in Science – Universe Expanding

One of the greatest unsolved mysteries in science is that our universe seems to be expanding and how and why this expansion has been quickening is not known. Academics this month recommended that it was owing to every point in space oscillating between expansion and contraction and instead of these changes cancelling each other out, there is a small net effect resulting in the universe to gradually expand normally.

A PhD student at the University of British Columbia, Canada, Qingdi Wang leading a team looking into these tiny fluctuations stated that space-time was not as static as it appeared and is continuously moving. This tends to take place at very tiny scales, billions and billions times smaller than even an electron.

 Physicists estimate that the expansion of the universe is due to the dark energy pushing matter away and though we are not aware of precisely what dark energy tends to be, there is something known as vacuum energy. It is said to be continuously altered by the fluctuation of virtual particles bursting in and out of way of life. It is said to be background energy created in the universe and is connected to uncertainty principle in quantum mechanics of Heisenberg.

Every Point in Space – Yo-Yoing – Expansion/Contraction

If the theory of quantum mechanics is applied to this vacuum energy concept it turns out to have additional energy than the total energy of all the particles in actuality. This would result in explosion of the place. Wang and Co had calculatedthat vacuum energy tends to be present without blowing apart the universe and have done so in a manner which puts the idea forward that every point in space is yo-yoing between expansion and contraction with a small increase in the direction of expansion.

Their effort had been published in Physical Review D recently. Co-author of their paper and a professor of physics and astronomy at the University, William Unruhhad compared the effects to waves rippling through an ocean.

The vacuum energy procedure is said to be alike the waves seen on the ocean. Unruh stated that they are not affected by the intense dance of the single atoms which makes up the water where the waves tend to ride. The fluctuations occur at the Planck scale at 10-33 cm which is complex to prove. However the researchers expect that it may indirectly be confirmed in the future.

Accelerated Expansion – Recognized Observation

Wang had explained to the Reg that accelerated expansion was already a recognized observation of the universe with tons of experimental consequences and their theory had explained this occurrence successfully. They would be generalizing the theory to be capable of clarifying the evolution of the universe in details, predict some latest patterns that could be examined in the near future in the interplanetary microwave background radiation.

Saul Perlmutter, Brian Schmidt and Adam Reiss, Nobel Prize winning astrophysicist had learned that the universe had been increasing at a fast rate in 1998. They found that the redshift for observed supernovae had been bigger than speculated. It recommended that the blowing up of stars had been moving at a quicker pace than believed earlier and the expansion of the universe had to be hurrying.

Mining the Moon Could Give Us Enough Rocket Fuel- Says Student Researcher

mining of moon

2017 Caltech Space Challenge

It’s been forty five years since man had last set foot on space and now the moon is said to be the focus of effort for not only exploring space but alsoto develop aenduring, independent space managing society.Scheduling an expedition to the nearest celestial neighbour of Earth is now no longer just an effort of NASA but the space agency of U.S has ideas for a moon-orbiting space station which would be serving as a performing ground for Mars mission in the early 2030s.

 A joint project – the United Launch Alliance between Lockheed Martin and Boeing has scheduled a lunar fuelling station for spacecraft with the potential of supporting 1,000 people living in space within 30 years. Billionaires Elon Musk, Jeff Bezos as well as Robert Bigelow have companies focussed on delivering people or goods to the moon.

 Many teams competing in partaking in the share on the cash prize of US$30 of Google are intending to launch travellers to the moon. Recently a few together with 27 other students from across the world had contributed in the 2017 Caltech Space Challenge suggesting designs on what a lunar launch and supply station for deep space mission could appear like and how it would function.

Moon – One-Sixth of Gravity of Earth

Presently all space missions depend on and are launched from Earth though its gravitational pull seems to be strong. In order to get into orbit, the rocket needs to be travelling 11 km a second – 25,000 miles per hour.

A rocket leaving Earth needs to carry the fuel essential to reach its destination and if needed to return back again. The fuel is said to be heavy and moving with it at such high speeds would take a lot of energy. If the refuelling is done in orbit, the launch energy could lift more travellers or cargo or scientific equipment in orbit.

The spacecraft could then refuel in space where the gravity of the Earth seems to be less powerful.The moon is said to have one-sixth of the gravity of Earth making it a pretty substitute base. Besides this, it also has ice wherein we are aware how to process into a hydrogen-oxygen propellant which can be utilised in several recent rockets.

The Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Satellite missions of NASA have now found considerable quantity of ice in long-lasting shadowed craters on the moon.

Prospector/Constructor/Miners

These would be tricky locations to mine since they tend to be colder and have no sunlight to power wandering vehicles. But big mirrors on the rims of the craters could be installed in order to illuminate solar panels in the permanently shaded regions.

Travellers set to launch in 2020 from Lunar X Prize competition from Google and Lunar Resource Prospector from NASA would also be contributing in locating good areas to mine ice. Based on where the best reserves of ice seem to be, it would be essential to build many small robotic moon bases. Each would mine ice, manufacture liquid propellant as well as transfer the same to passing spacecraft.

A plan of accomplishing these tasks with three various types of ramblers had been developed by the team. The plan also needed some small robotic shuttles in meeting up with nearby deep-space mission vehicles in lunar orbit. One of the rover known as Prospector would be exploring the moon and locate ice-bearing areas.

A second, the Constructor would be following along behind constructing a launch pad and packing down roadways to ease movements for the third kind of rover, the Miners. This would in fact amass the ice, delivering it to the nearest storage tanks and an electrolysis processing plant which tends to split water into hydrogen and oxygen.

Landing Pad – Lunar Resupply Shuttles

Moreover, the Constructor would also be erecting a mooring pad wherein small near moon vehicle spacecraft called Lunar Resupply Shuttles would be arriving for the collection of fuel for delivery as lately launched spacecraft pass by the moon.

The aircrafts would utilise the moon-made fuel and have advanced guidance together with navigation systems for travel between lunar bases and their object spacecraft. With the provision for adequate fuel being produced and the aircraft delivery system is tested and dependable, their intentions are for building a gas station in space.

The aircraft would be delivering ice straight to the orbiting fuel depot after which it would be processed into duel and where the rockets heading to Mars or any other area could dock to refill. The depot would be equipped with large solar arrays powering an electrolysis module for the purpose of melting the ice and later turning the water into fuel together with huge fuel tanks for storing what is prepared.

NASA has been operational on most of the technology essential for a depot such as this comprising of docking and fuel transfer. A working depot is expected to be ready in the early 2030s in time for the first human missions to Mars.

Earth-Moon Lagrangian Point – L1

The depot needs to be placed in a stable orbit probably near the Earth and the moon to be most useful as well as effective.The Earth-moon Lagrangian Point 1 – L1 is said to be a point in space around 85% of the way from Earth to the moon wherein the force of the gravity of the Earth would match the force of the gravity of the moon pulling in the other direction.

It seems to be an ideal pit stop for a spacecraft going on its way to Mars or the external planets. The team also located a fuel-efficient system of getting spacecraft from Earth orbit to the L1 depot which needed much less launch fuel and reducing more lift energy for cargo items. Initially, the spacecraft would be launching from Earth into Low Earth Orbit with empty propellant tank and then it could be towed with its cargo from Low Earth Orbit to the L1 depot utilising solar electric force tug, which is a spacecraft largely propelled by solar-powered electric thrusters and this would triple the payload delivery to Mars.

By assisting us in escaping the gravity of the Earth as well as its necessity on the resources, a lunar gas station can be the initial move to the big leap in making humankind a space civilization.
