  • 11:37: ... decay,   and we saw how this can lead to the creation  of cosmic strings in a recent episode.   But cosmic strings are the perhaps ...

2022-03-08: Is the Proxima System Our Best Hope For Another Earth?

  • 16:48: And the one on cosmic strings - topological defects that may span the length of the universe.
  • 18:27: OK, on to cosmic strings.
  • 18:33: When those cosmic strings radiate gravitational waves, how is the Higgs field supposed to smooth itself out?
  • 19:20: Or are cosmic strings the only indication of a change in phase angle?
  • 19:45: I don’t know how you’d do this besides observing a cosmic string, but I suspect there are ways.
  • 19:51: ... Scoot asks whether cosmic strings could explain the filaments and voids in the large scale distribution of ...
  • 20:03: So the answer is maybe to the first two - but only if cosmic strings influence the CMB.
  • 20:24: ... structure is defined by those density fluctuations, so in that sense cosmic strings could have influenced it - but not directly in the sense of cosmic ...
  • 20:38: ... dark matter - extremely unlikely - in our most accepted understanding of cosmic strings there aren’t anywhere near enough of them to account for dark ...

2022-02-23: Are Cosmic Strings Cracks in the Universe?

  • 00:00: ... defects stretching across the sky. These are   cosmic strings, and many physicists think that they have to exist, and that we can ...
  • 00:58: ... formed from topological defects in the quantum fields, aka cosmic strings. They have subatomic   thickness but prodigious mass and they ...
  • 07:33: ... swirl around a central line.   And that central line is our cosmic string. Other topological defects may be possible.   For example, a ...
  • 08:50: ... the universe.   Unlike the topological defects in ice,  cosmic strings move and vibrate. They are   also under pretty insane tension, ...
  • 10:09: ... causes them to radiate   gravitational waves. In this way cosmic strings  shed energy, and so they slowly decay away.   Eventually they ...
  • 12:19: ... may give us the data that we need to find these. Now if we do find a cosmic string, there’s one   other point of confusion we’d need to ...

  • 13:48: And, ultimately, to ally with them in war against the cosmic string entities in the heart of the Sun that we discussed recently.

2020-09-28: Solving Quantum Cryptography

  • 14:24: Last week we talked about a highly speculative idea - lifeforms inside stars, formed from cosmic strings and magnetic monopoles.

2020-09-21: Could Life Evolve Inside Stars?

  • 00:16: Oh, and here’s an extra crazy one - life composed of cosmic strings and magnetic monopoles, evolving in the hearts of stars.
  • 01:03: ... that fundamental kinks and defects in the fabric of the universe - cosmic strings beaded with magnetic monopoles - may evolve into complex structures, and ...
  • 01:28: What exactly are cosmic strings and magnetic monopoles?
  • 01:38: Cosmic strings and magnetic monopoles are what we call topological defects.
  • 03:56: A 1-D topological defect is a cosmic string - an extremely thin filament.
  • 07:00: Others have speculated that cosmic strings may get trapped inside stars in the process of star formation.
  • 09:50: ... going to have to get a much better understanding of cosmic strings and monopoles - and, you know, actually verify that they exist in the ...
  • 11:28: ... those who don't know, James is a higher being composed of cosmic strings and monopoles, visiting Earth from the core of the Sun to help spread ...
