This is all about Gravitational Waves

In February 2016, Albert Einstein made history again. Currently, physicists have declared that he has determined the great theories that scientists have determined 100 years before: the waves of gravity.

The first laser-gravitational Observatory of Interferometer (LIGO) was first confirmed in the gravitational wave-space-distortion distances, literally completing the universe of the universe – an extraordinary task of earning the Nobel prize for key developers.

The latest sources of the waves are as fantastic as the detected engineering: two broken black holes, large gravity that sends undulations all over the cosmos.

This result, the longest climax, 

But when he resolved the problem of presence or not of the wave of gravity, he was also the starting point for a new journey.

First, astronomy is based on only electromagnetic radiation and exotic particles such as neutrino and cosmic rays. But small-scale gravitational forces, along with new capabilities to see, have brought new ways to studying the universe.

The gravitational wave provides free play on a fixed-line research, when announcing the phenomenon that has never been found and can not imagine.

Excessive (and unavailable) about a brutal incident between black holes and super-objects, the gravitational wave may also show us what appeared in a small part of Big Bang itself. They can also show us how the universe has expanded since then.

And when it comes to gravitational waves confirm Einstein’s solid principles, researchers can now comply with the general relativity for the most severe tests, perhaps ending the disability.

The researchers have studied five topics that started for exploration during the astronomical wave of gravity.

The first black hole

In the sense, the black hole is a simple object. Each point in the universe is done with mass more than it can be handled, it can form singularity – an almost infinite point where the rule of ordinary physics rules. No one comes close, including light discourse, can eliminate the attraction of gravity.

In the middle of every black hole, astronomers believe, lies the singularity of this kind.The oldest black hole found more than 13 billion years ago, around 690 million years after the Big Bang, but the former will have a previous period: in the small part of the Big Bang.

With these assumptions, these primordial black holes differ from those of the more general ones, which are formed when large stars nile nuclear fuel and can not resist their own gravity.

As a result, when a normal black “star” hole is regarded as a combined feature of the universe, the primordial black hole has remained hypothetical and mysterious half-century. But the new technique, based on the gravitational wave, can cause its occurrence.

Astrophysicists Savvas Koushiappas from Brown University and Avi Loeb from Harvard University have come up with a simple way to find primordial black holes. It is a move to the gravitational ripples caused by colliding black holes ancient, the best way to detect today.

The primordial black hole was first proposed in 1966 by Russian scientists Yakov Zeldovich and Igor Novikov. Stephen Hawking was developed over the next five years. Since then, researchers have been searching for evidence in the primordial black hole.

The duo started believing that in primordial primordial universe the black hole was the only possible type, because it was a black star hole that could not be formed before the stars.

Then, if it is possible that a pair of black bores can occur, explaining that any gravity ripples seen before must be caused by a primordial black hole.

Based on the conservative hypothesis, they found that the first black star hole would not be formed and would cost up to 67 million years after the Big Bang.
