2021-08-03: How An Extreme New Star Could Change All Cosmology

  • 09:18: ... together because they emit gravitational radiation that saps away their orbital energy. We’ve seen the result of this with black holes and neutron stars when ...

2020-01-27: Hacking the Nature of Reality

  • 14:29: ... some places it gives up angular momentum - it's orbital energy - to the gas, causing it to migrate inwards, while in other places it ...

2020-01-13: How To Capture Black Holes

  • 00:59: ... of space into expanding ripples - gravitational waves - which saps orbital energy from the system. The black holes spiral closer and closer together. In ...
  • 05:58: ... hole pair gets captured by the disk, the surrounding gas saps their orbital energy much more quickly than by gravitational radiation alone. This means they ...

2019-06-06: The Alchemy of Neutron Star Collisions

  • 02:47: ... slowly spiral towards each other as a gravitational radiation saps their orbital energy in the last minute before merger that radiation is so strong that it'll ...

2018-08-01: How Close To The Sun Can Humanity Get?

  • 07:17: Venus will end up traveling infinitesimally faster as it absorbs Parker's orbital energy.

2018-03-28: The Andromeda-Milky Way Collision

  • 06:20: When those black holes are around a light year apart, they'll start losing orbital energy to gravitational waves.

2017-10-04: When Quasars Collide STJC

  • 07:35: Each time they do that they lose a bit of orbital energy or angular momentum, causing them to fall deeper into the gravitational well.

2017-09-13: Neutron Stars Collide in New LIGO Signal?

  • 03:30: The rate of loss of orbital energy exactly matches the expected rate of emission of gravitational radiation.

2016-04-06: We Are Star Stuff

  • 09:27: ... those remnants will eventually spiral in as they radiate away their orbital energy in gravitational ...

2016-02-11: LIGO's First Detection of Gravitational Waves!

  • 02:30: But gravitational waves carry energy, which is sapped from the orbital energy of the system.
