LISA Gravitational Wave Observatory

The Laser Interferometer Space Antenna or LISA mission will study the mergers of supermassive black holes, test Einstein's Theory of General Relativity, and probe the early Universe. Detecting gravitational waves is a new way to observe the Universe. Through them we will learn more about the mergers of giant black holes and the death spirals of stars that black holes capture and swallow. LISA will look for gravitational waves coming from our Galaxy and other galaxies. LISA will also map the structure of space and time around black holes and determine if Einstein's theories are correct.

Great thank you. Any chance of a real voice? I'm sure yours is lovely.

[BrunoTheQuestionable]

I haven't overcome my mic shyness yet, but thanks for the vote of confidence. I love your accent btw :)

[AmyK007]

Thats kind of you thank you. Just give it a go and don't worry what other people think. Just make sure that you are clear and precise and read from a script if you like. You posted such a good video, with a great voice, you'll get science enthusiasts like me subscribing in no time. My best wishes to you my friend.

[BrunoTheQuestionable]

Thanks for the good advice - I might try it sometime.

Very ANNOYING to hear this imperfect artificial voice! The subject is fascinating but this 'guy' sounds like he's about to burp all the time. For gods sake just belch and continue. stupid choice on part of video producer. Great info though.

interesting - but poor voice :)

[Aasmaema]

its three due to triangulation, as in trigonometry, it has nothing to do with the levels of dimensions

[canisslav]

no information can travel at a speed greater than the speed of light.

What if gravity propagates at infinite velocity? How then would we measure the duration of such a wave? Get it? Infinite velocity = infinitesimal time span!

ok people stop saying this is the voice of stephen hawkings, just because it is a computer generated voice doesnt mean its stephen hawkings, his computer's voice doesnt sound anything like that.

..and i think they'll need 4 points (spacecraft) to get a better 3D (seems that we need 4D here) understanding.

I wont torture myself whit this fucked up computer voice, your video sucks

[anomoly76]

I remember a black project scientist claiming he worked on vehicles that warp the distance/time and thats how the craft traveled in very high speeds. I think the new concept he introduce was there are gravity waves at the macro and micro level. So the theory is if you could access the atomic gravity wave (micro) and amplify it to a larger wave, you can see the affects of time/distance changing. Hopefully the LHC might bring us a step closer to show evidence of gravity in the micro realm.

Ok all you idiots making WTF comments about the voice need to STFU. It's obvious that it's computer generated and it is most likely the voice of world-renowned theoretical physicist Stephen Hawking. If you knew anything about him, you'd know that he is confined to a wheelchair and cannot speak because of neuromuscular dystrophy. In simple terms, HE'S PARALYZED. He CAN'T talk or "fix his voice" so ease off the voice comments. Have some respect for the guy.
