LIGO and NASA may have observed a gamma-ray burst from colliding black holes

LIGO and NASA may have observed a gamma-ray burst from colliding black holes Just to produce the gravitational waves LIGO observed, the cataclysm liberated the mass energy of three of our suns — in less than a quarter of a second.Merging black holes take millions of years to collide.

Why gravitational wave detection may have also revealed dark matter

These would be very large for primordial black holes, but technically allowable based on preexisting model for their creation.What this means is not only that gravitational wave detectors could be used to investigate the nature of dark matter, via investigating these black holes, but that gravitational wave detectors already have investigated dark matter.

This week in space: gravity waves, NASA’s Mars shot, and a new ‘super Jupiter’

This week in space: gravity waves, NASA’s Mars shot, and a new ‘super Jupiter’ That’s why LIGO wants your help, or at least your computer’s.President Obama told the nation he thinks it’s pretty important that we send humans to Mars “by the 2030s.

LIGO's black hole detection survives the gravatstar test

LIGO's black hole detection survives the gravatstar test The original idea was that the first confirmed detection of gravitational waves was the result of a binary black hole event: two black holes meeting in space, spiraling inward, and eventually merging.Now, a new test has examined the idea that what LIGO actually saw was not the merger of two black holes, but the merger of two gravastars.

Two 'L'-shaped observatories with lasers: How to find ripples in space and time

Two 'L'-shaped observatories with lasers: How to find ripples in space and time However, the ripples — known as gravitational waves — are extremely difficult to detect.Scientists took this into account in designing LIGO by constructing two identical arms with a laser running through each.

These scientists are proving Einstein wrong

These scientists are proving Einstein wrong Albert Einstein’s theories have been influencing physics for over 100 years.Until recently we haven’t had the technology to test these theories.

Ripples in space and time carry the future of space science

Ripples in space and time carry the future of space science Billions of years ago, two black holes merged in a violent explosion that rippled the fabric of our universe.Those cosmic ripples — known as gravitational waves — produced by this collision spread far and wide in all directions, carrying with them information about the black holes that brought them into being.
