Gravitational Wave facts

While investigating facts about Gravitational Waves and Gravitational Waves Detected, I found out little known, but curios details like:

Einstein's gravitational wave theory was proved right 100 years later

how gravitational waves are detected?

Author HG Wells pretty much created the template for the modern day disaster movie with his 1897 short story "The Star". It tells of the Earths near miss with a meteor who's gravitational pull causes earthquakes, tidal waves, and the melting of the ice caps. Millions are killed.

What causes gravitational waves?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the speed of gravitational waves. Here are 21 of the best facts about Gravitational Wave Detector and Gravitational Waves Discovery I managed to collect.

what are gravitational waves?

1. Much of his research has focused on the mathematics and the engineering design analysis of gravitational waves.

2. Two blackholes colliding into each other would cause gravitational waves with energy much greater than what the observable universe releases.

3. He founded LIGO (Laser Interferometer Gravitational Wave Observatory) which is a large, multi-institutional gravity-wave experiment to measure any fluctuations between two or more static points.

4. In 2015, we detected, for the first time, the merger of 2 black holes by measuring the gravitational waves emitted by the collision that happened 1.3B ago

5. Detecting gravitational waves is like measuring the distance from Earth to Alpha Centauri accurate to within the width of a human hair

6. Joseph Weber invented the first gravitational wave detectors (Weber bars) in the 1960s, declared victory, but was aggressively discredited at MIT in 1974

7. Plasma can travel close to the speed of light on gravitational waves because of Landau damping

8. Gravitational wave detectors such as LIGO can detect motions 10 thousands times smaller than the nucleus of an atom

9. Sounds waves actually carry a small amount of mass (about as much as a single helium atom), and their gravitational mass is negative. (Link leads to the abstract, which has a pdf of the full study available for download.)

10. The US Navy has recently patented several radical aviation technologies including designs for a high frequency gravitational wave generator, a room temperature superconductor, an electromagnetic force field generator, and an inertial mass reduction device

Why gravitational waves?

You can easily fact check why do gravitational waves travel at the speed of light by examining the linked well-known sources.

Europa's oceans have waves due to the gravitational pull of Jupiter tilting its moon.

Nobel Prize winner built Laser Interferometric Gravitational Wave Observatory to proof the exist of gravitational wave and they measured the phase change of light to proof the gravitational wave existence - source

A scientist called Joe Weber detected evidence for gravitational waves 4 decades before the current findings - source

They could simulate the sound of two Black holes colliding in space from gravitational waves

They could simulate the Sound of two Black holes colliding in space from gravitational waves - source

When gravitational waves detected?

In August of this year(2017) two neuron stars merged together and produced a gravitational wave, marking a breakthrough in Multi- messenger astronomy

How gravitational waves are produced?

We are building a telescope that "sees" with gravitational waves (literally compression waves of spacetime itself) instead of light.

One of the only two observatories in the U.S. that observe gravitational waves, is located in my home state (Louisiana) and only a 30 minutes drive from where I currently live!

The collision of two black holes that generated the first ever detected gravitational waves (by the LIGO) was such a violent event that the explosion briefly released 50x the energy output of every star in the observable universe.
