What caused the gravity waves? The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae (massive stars exploding at the end of their lifetimes), and colliding neutron stars. What is gravity waves? Gravity waves or Gravitational...
Can humans feel gravitational waves? Gravitational waves spread out from any violent event involving matter – such as, say, the collision of two black holes. Like gravity, however, they’re incredibly weak, so you’d have to be extremely close to their source...
Is gravity a wave? Gravitational waves are ‘ripples’ in space-time caused by some of the most violent and energetic processes in the Universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. Is gravity...
How is LIGO funded? LIGO is funded by NSF and operated by Caltech and MIT, which conceived of LIGO and led the Initial and Advanced LIGO projects. How many LIGO are there in the world? A Nation-Wide Research Facility Although it...
What is LIGO in space? It is the world’s largest gravitational wave observatory and a marvel of precision engineering. Comprising two enormous laser interferometers located 3000 kilometers apart, LIGO exploits the physical properties of light and of space itself to detect...
When did LIGO detect gravitational waves? All of this changed on September 14, 2015, when LIGO physically sensed the undulations in spacetime caused by gravitational waves generated by two colliding black holes 1.3 billion light-years away. LIGO’s discovery will go down...
Why do galaxies collide Will stars almost never do? stars are much further apart (compared to how big they are) than galaxies are stars have very strongnegative charge on them so they repel other stars that get near stars are surrounded...
What method would astronomers use to find the distance to a galaxy so far away? Astronomers can use what are called surface brightness fluctuations (SBF, for short), along with the color of a galaxy, to calculate how far away it is...
What things can happen to galaxies when they collide? Merging galaxies can also trigger the creation of new stars. Galaxies are also composed of gas and dust. The gravitational pull of both colliding stars can interact with this materials, creating friction...
What does the cosmological principle say about the universe? The second assumption, called the cosmological principle, states that an observer’s view of the universe depends neither on the direction in which he looks nor on his location. What is the cosmological...
