Space-based relativity experiment is crucial to the search for gravitational waves

Space-based relativity experiment is crucial to the search for gravitational waves But one upcoming test of Einstein’s relativity won’t just be important to theoreticians.The idea is to put these weights into perfect — and I do mean perfect — free fall.

Gravitational wave science gets go-ahead to revolutionize astronomy

Let’s be honest: while the recently announced proof of the existence of gravitational waves was undeniably an enormous, exciting moment for science, it didn’t really accomplish much all on its own.It’s important that scientists have proven the existence of gravitational waves — but not in the least bit surprising.

Lightweight black hole merger detected, offering new insight into gravity

It turns out that the black holes from the original detection were probably actually born within the same star, and so the period of time from their birth to their merger was essentially nil.But these two lighter black holes spend about a second in the “sensitive band” of the frequency spectrum, creating gravitational waves LIGO can detect.

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.

Hubble uses gravitational lens to look back at the early universe

Hubble uses gravitational lens to look back at the early universe Those galaxies are from the very early universe, just a billion or so years after the big bang.This creates a natural lens, through which Hubble can look to get a clearer view of objects on the other side.

The so-called fifth force of nature is starting to look more and more real

The so-called fifth force of nature is starting to look more and more real They found that this new particle should be about 30 times heavier than an electron, or about 17 MeV (megaelectronvolts).Such a dark force would be useful in revealing the nature of WIMPs, the theorized mass-carrying particle that makes up dark matter.

New evidence strengthens the case for ‘Planet 9’ in the outer solar system

New evidence strengthens the case for ‘Planet 9’ in the outer solar system In fact, we aren’t 100% sure we’ve found all the planets in our own solar system.In a new study published in The Astronomical Journal, scientists present compelling evidence for the existence of a large planet orbiting at the edge of the solar system.

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.
