  • 11:10: ... of pure general relativity,   and assume the various energy conditions. We know that general relativity is not the entire   ...

2020-04-22: Will Wormholes Allow Fast Interstellar Travel?

  • 09:11: In general, exotic matter violates the so-called energy conditions of general relativity.
  • 09:17: ... equation in order for those equations to make physical sense. But these energy conditions are more guidelines than rules, and have been observed to be violated in ...

2019-10-21: Is Time Travel Impossible?

  • 06:33: These are the so-called energy conditions.
  • 06:42: But the energy conditions don’t have a really fundamental basis, and they're seen to be violated in some cases – like with the Casimir effect.
  • 06:51: We can’t completely rule out wormhole or warp drive time machines based just on the energy conditions.
  • 06:42: But the energy conditions don’t have a really fundamental basis, and they're seen to be violated in some cases – like with the Casimir effect.

2019-03-28: Could the Universe End by Tearing Apart Every Atom?

  • 12:11: ... in a way far worse than regular dark energy. It violates the same energy conditions of general relativity that prohibit negative mass and time ...

2019-01-30: Perpetual Motion From Negative Mass?

  • 09:32: It also violates the energy conditions of general relativity.
  • 09:46: ... fact the mere existence of negative mass breaks certain energy conditions, but the prospect of a bottomless well of infinite negative energy breaks ...
