1. If the merger of black holes happen at or beyond the event horizons, how can they be observed in our universe?
2. Are you an elf?
3. How Many Black holes merge in a year? seem like it happens a lot.
4. I have a question about the nature of gravity's effects on spacetime. I understand that gravity as we know it is really just the warping of 4-dimensional spacetime, but, what drives matter (previously unaffected by gravity) to coagulate into larger and larger structures when the gravitational effects of bent spacetime are negligible at small, even molecular scales of matter? An example of this paradox would be the formation of stars and planets, where particulate matter spontaneously forms structures on the macroscopic level.
   
   This brings me to my main point: although time dilation is considered to be an effect of the bending of spacetime by matter, is it possible that it could be the cause of the spontaneous nature of matter to coagulate? Since there isn't (to my knowledge) a coherent mechanism for why the bending of spacetime causes matter to coagulate on small scales that doesn't result in circular reasoning, could an argument that (bear with me here) parallels Newton's law of entropy be made?
   
   Since gravitational effects and relativistic velocities are the only things that are known to slow time to an outside observer, and both are tied to incredible mass contained in a small area of spacetime, could the most 'entropically' (I use that term with a heavy grain of salt, as we are far past Newtonian physics) favorable state of spacetime be one in which the advancement of time stops, such as beyond the event horizon of a black hole? If this were the case, it could potentially be the cause for the seemingly spontaneous nature of gravitational effects, even on small scales.
   
   Is this a plausible explanation for the spontaneous nature of the warping of spacetime? The mathematics are far beyond my capabilities, and I would like some feedback from someone who truly knows what they are talking about. Also, If my understanding of the physics of these concepts is wrong, then please correct me, I'm just a curious undergrad and wide open to criticism.
5. Would a spirit level work near a black hole?
6. What would happen if two solar mass black holes collided dead on at 20% the speed of light or faster?
7. isn't it obvious if an object bends space-time while stationary when that object moves it will cause waves in space-time? why does this have to be proved?
8. Just sharing some thoughts (mostly questions) here on the subject : Is it possible and what would happen if a gravitational wave encounters another one and create constructive interference patterns?
   Does the gravitational wave dissipate? If so what would dissipate it? And finally what governs the propagation speed of a gravitational wave?
9. Fucking publicity is ... laughing my mind. I'm living in Quebec province, so, a province publicity from Hydro-Quebec. Even though I believe in this form of energy, it's quite laughing that this is the "solution"
10. I love Pbs Space Time  :D
11. Merging black holes. If it was excepted that two black holes merging create a brown star, and that a black hole attracts light, then a star that died and had not yet conjoined would absorb all it's moons or planets and If their combined mass was sufficiently larger than the new black hole, they might contain it at an event horizon and create a gas planet. If our Sun became a black hole it would be attracted to our brightest or nearest star. A contest. Gravity V light. On meeting. The star, dependent on it's mass would be held at a distance to be slowly devoured by the black hole or it could dominate and absorb the black hole, causing increased internal gravity that would squeeze the photons out of it faster. Logic would suggest that a super bright larger star with a reduced life expectancy might result.
12. Could quantum computing in the future help detect the waves on a subatomic or quantum level?
13. Idiot
14. at 5:26, what is going on near his feet?
15. Would a gravitational wave be restricted in velocity to the speed of light seeing that it is a fluctuation of space and necessarily move "through" space?
16. So we can detect the gravitational waves of colliding black holes we assume to know about ... how can we be so certain we arent detecting ones we dont know about??
17. I won!! Got my t-shirt yesterday and just now found this follow up video!!! Hurrah! Thank you Space time, y'all are the best
18. How fast would a black hole have to spin to rip itself apart, assuming 30 solar masses?
19. Are Gravitational Waves faster than Light?
    And if we 'see' Black holes merging, can we see them Disintegrating?(Not Hawking Radiation)
