Physicists Just Spotted Gravitational Waves Again, So What’s Next?
Long ago, long ago, a couple of black holes turned out to have such power that they created waves in space-time, coming from the universe. All the time, molecules on a small rock in a rather irrelevant corner of the Milky Way settled into living beings, moving toward self-conscious monkeys. These monkeys have realized that they could actually measure space-time oscillations and machines built several kilometers (in lowercase if you really think). When they turned the switch, they caught the oscillations in time.
But they saw another series of oscillations, and the indexes of another (although they were not sure). Now they have confirmed a third case, and he made monkeys wonders: what does all this mean? And where do we have here?
This week, the pair of gravitational wave laser observers (LIGO) confirmed the detection of a third set of these gravitational waves predicted by Albert Einstein first more than a hundred years ago. While the third discovery remains almost as exciting as the first and second, scientists are beginning to think about what these waves can tell you about our universe and what they can do once they have seen many.
Scientists have accused two LIGOs of observing gravitational waves, one in Washington and one in Louisiana. They are essentially a pair of perpendicular rulers made of light, in which the optical systems divide a laser, send the long beams of down tubes and attach them to a detector. If a roll of gravitational waves, the amount of space that must pass light through the changes, the movement of the two beams in and out of alignment and creating a waveform in a graph. Scientists need two LIGOs to confirm that the observation was nothing more than a truck. And a similar observatory, called Virgo, is now active in Italy and will soon join the LIGO to better determine the origin and behavior of gravitational waves.
“This event is not a clear test, but it is the first event for which we prefer a more serious scenario over another”
The LIGO saw this biggest wave event, GW170104 on January 4 of this year. They used the waveform to determine that it is a pair of black holes colliding three billion light years, approximately 31 and 19 times the mass of our Sun and become a single black hole of about 49 times the mass and Published their findings in the weekly Physical Review Letters Week. The mass of this black hole fits nicely between the mass of black holes deduced heavier and lighter waves previously measured. The waveform also provided some tempting suggestions to answer the question of how a couple of black holes end up turning in orbit in the first place.
A black hole could form either from a pair of orbiting stars that collapsed or if a black hole would pass through each other and followed its example in its severity. In the first case it was true, the spines of the black holes would line up in their orbits. But if the turns were in the opposite direction of the orbits, the second scenario is more likely. The last observation of gravitational waves begins to gather the scientists to the second case. This is certainly not conclusive, but it means that in the distant (and therefore younger) universe, there may be places with concentrated black holes coming together, said Gizmodo Imre Bartos, associate researcher at Columbia University.
“This event is not a clear test, but it is the first event for those who prefer a more serious scenario over the other,” said Salvatore Vitale, assistant professor at MIT, Gizmodo. “If you ask me, I think it’s too early to say anything conclusive,” he said.
