Janna Levin: The sound the universe makes

http://www.ted.com We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a drum.) An accessible and mind-expanding soundwalk through the universe.

[platomica]

aside of these banging ideas, i really like how she sweats...

now please some bitchslap me. ;-)

wiki hawking radiation, mass and energy can escape such that the hole will lower in mass and eventually vanish, but visible sprectrum light stil cant escape, so i think its still fair to call it a black hole, singularity is just a fancy pants name, its still black

[Justin Corcoran]

um actually "black" holes is a misnomer this is bullshit. some of the singularities as they are better called emit more energy than they consume.. in the form of the full spectrum of light all the way into xrays and gamms.. so black holes are all neccesarily dark spots

[mastertheillusion]

Brilliant.

[Blair Draper]

Very interesting- although at some points it reminded me of watching a sermon in church. Just for a technological religion
