Gravitational Waves | John Mather | TEDxHerndon

Dr. John Mather discusses Gravitational Waves and the future of astrophysics. Dr. Mather is the recipient of numerous awards, including the Nobel Prize in Physics (2006) with George Smoot, for the COBE work, and the NASA Distinguished Service Medal (2007). He is a member of many professional societies including the National Academy of Sciences and the American Academy of Arts and Sciences.

Dr. John C. Mather is a Senior Astrophysicist and is the Senior Project Scientist for the James Webb Space Telescope at NASA’s Goddard Space Flight Center in Greenbelt, MD. His research centers on infrared astronomy and cosmology. As an NRC postdoctoral fellow at NASA’s Goddard Institute for Space Studies (New York City), he led the proposal efforts for the Cosmic Background Explorer (74-76), and came to GSFC to be the Study Scientist (76-88), Project Scientist (88-98), and the Principal Investigator for the Far IR Absolute Spectrophotometer (FIRAS) on COBE. With the COBE team, he showed that the cosmic microwave background radiation has a blackbody spectrum within 50 parts per million, confirming the expanding universe model (aka the Big Bang Theory) to extraordinary accuracy, and initiating the study of cosmology as a precision science.

Blown away by how well Dr Mather explains the history of how we managed to get to the point where we can detect gravitational waves. I absolutely love the simplicity of his explanation, the time just flew by.

Very interesting, it's the first time I understand something about gravitational waves

[popandfizzletigerstyle]

I have a theory on dark matter. Dark matter is gravity in a liquid state where what we think of as matter is compressed to smaller than subatomic particles. This would explain how is can make up about 90% of the galaxy's mass without emitting heat or light.

If you want to know more about gravitational waves and what astronomy still has to discover, read the Contact Notes of Billy Meier.

i like your tie, its very interesting.

[twogamer]

imagine vehicles propelled by gravitational force

Speed of light is not a constant. Light has an induction rate not a speed. It's a coaxial circuit..
Space has no attributes.
The sun is electrical not nuclear.. this guy said no one has found the slightest mistake.. he's absolutely incorrect.
Gravity is incoherent magnetism / dielectric acceleration.

Warped space: does space pinches in or bulged arround matter.(space or space time...)

[ZennExile]

You would think these guys could handle some basic sound levels, but nope. Get it together...

Dr. Thorne, who is now retired from LIGO.
Dr. Drever, who has dementia and lives in a nursing home near Edinburgh, is not able to enjoy the victory lap.
Dr. Weiss, who is retired with emeritus status at M.I.T.

Hi I have questions about the laws of thermodynamics 1 / The first law says that energy does not end 2 / The second law says that energy is constantly decreasing .There are contradictions between Law I and Law II .We ask you to find solutions to this problem

Newton is like rocker guitarist of some band..

It annoys me when people have to start every paragraph with 'So...'

feather and a hammer drop them and they don't hit the ground at the same time....flunk

[gsanewphysics]

Gravitational waves are not part of the electromagnetic waves. Gravitational waves and electromagnetic waves are quite different. The speed of light in vacuum, not the speed of gravitational wave.

Einstein never predicts ripples in spacetime come from two black hole collide, he didn't believe in black hole. He predicts in 1916 riples in spacetime come from two celestial bodies in orbit. In orbit and collide/merger are quite different.

Why do you lie? Not every matter react the same when you let them fall. There is no gravity, there is only magnetic fields!!
Please please let people know the facts not what you want them to believe! Be Human!!!
