Gravitational Waves | John Mather | TEDxHerndon
About | Information | History | Online | Facts | Discovery
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. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

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. -
The microphone, was not so good
-
i like your tie , its very interesting.
-
You would think these guys could handle some basic sound levels, but nope. Get it together...
-
He meant Interstellar for Kip not Gravity. Gravity was so shit, Interstellar was great.
-
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.

It annoys me when people have to start every paragraph with 'So...'
-
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. -
first lol
-
wow this guy sucks at presenting information

Hello!
Ive just recently my own company and it would mean the world to me if you could visit it and give me feedback on it. Just simply search for "Almoj" and click the top link. Just for you guys use the code "SAVE20" for 20% off.
Like = Good luck! -
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!!! -
ما ادري سيقول بس أكيد شي مهم
-
Very interesting, it's the first time I understand something about gravitational waves
-
wow so early!
God does not exist, our life is short, meaningless and purposeless. Death will come soon enough to pull us back in the abyss of non existence we were before we were born.
Have a good day :) . -
