Gravitational Wave
（Sample：TED Speaking《Discover gravitational waves》AllanAdams）
1.3 billion years ago
in a distant, distant galaxy
Two black holes locked into a spiral
falling inexorably towards each other
and collided
converting three Suns worth of stuff
into pure energy in a tenth of a second
making the universe explode in gravitational waves
On September 14th, 2015
the day that's definitely going to live in my memory
LIGO heard this…
(Gravitational Wave's reading sample…)
Audible sound has a wavelength that can be up to 50 feet long
and that makes it really difficult in fact——
in practical purposes impossible
——to make an image of something you really care about
Instead we use sound to listen
for features like pitch and tone and rhythm and volume
to infer a story behind the sounds
The same is true of gravitational waves
We can't use them to make simple images of things out in the universe
(But) By listening to changes in the amplitude and in the frequency of those waves
we can hear the story that those waves are telling
And at least for LIGO
the frequencies that it can hear are in the audio band
So if we convert the wave patterns into pressure waves in air into sound
we can literally hear the universe speaking to us
Our job now is dream big
Dream with us！
We face the world ,searching for the end of physics.
We measure with precision, calculating the scale of light
We march, we fall,
we stand, we climb
