Discussion Overview

The discussion revolves around the conditions necessary for Bose-Einstein Condensation (BEC) to occur on a planet, particularly in the absence of a nearby energy source like a star. Participants explore the implications of distant stars and nebulae on atomic movement and the potential for BEC in various cosmic environments.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • One participant questions whether distant stars could provide enough energy to prevent BEC on a planet, suggesting that the presence of a single star might only affect one side of the planet.
  • Another participant challenges the relevance of "moving" atoms and energy sources to the formation of BEC, noting that superfluids and supercurrents can exist without complete cessation of atomic movement.
  • A different viewpoint asserts that BEC cannot form naturally in space due to insufficient cold temperatures, except in extreme conditions like quark stars or neutron stars.
  • One participant proposes that nebulae composed of hydrogen, helium, or nitrogen could act as a supercooling system, potentially containing superconductive materials under the right conditions.
  • Another participant emphasizes that BEC can occur in various forms, including in superconductors and superfluids, which do not require temperatures as low as a few billionths of a degree above absolute zero.

Areas of Agreement / Disagreement

Participants express differing views on the conditions necessary for BEC, with no consensus reached on whether distant stars or nebulae could influence its formation. The discussion remains unresolved regarding the specific mechanisms and temperature requirements for BEC in cosmic environments.

Contextual Notes

Participants highlight limitations in understanding BEC, including the need for clarity on definitions and the mechanisms involved, as well as the influence of cosmic conditions on temperature and atomic behavior.

If there was a planet and there was no real energy source near it (say like our sun) would a few stars around 100million light years away on all sides of the planet(like our stars) be enought to keep atoms on the planet moving enough to stop BEC, or would BEC occur. Also if there was only one star, then would BEC also be occurring on the other side (that is if one star is enough to stop BEC on the side its shining on) Please give a good explanantion as to why.

Er... back up a bit.

What do "moving", another star, or "energy source" have anything to do with the formation of BEC? You do know that superfluids and supercurrent, by their definitions, are "moving" entities, and that these things need not occur at temperatures where everything stop moving, don't you?

BEC's don't form at temperatures naturally like that. In order for a BEC to for you would need either a very unusual phenomenon or for human interaction. Space doesn't get cold enough to form a BEC, so therefore it wouldn't form anywhere in space naturally. Though in some quark stars, neutron stars, and other unusual situtations they have been theorized to be.
 
This thread started me thinking that a huge Nebula of Hydrogen, Helium or Nitrogen could be in some areas a Super cooling System, It got me thinking that some of the Nebulas might contain Activated Super Conductive Material Naturally if the conditions were right and in such a huge system the chances should be great I would think.

A Nebula Storm of Nitrogen at say a 1000 miles an hour would be chilly Willy.

Thanks for making things click.:bugeye:

If this thread made you think of such things, then you have a vivid imagination based on what wasn't even said. I don't think this thread can take such "credit".

BEC wouldn't work in space because it is a few degrees above absolute zero, do to the radiation left behind form the big bang. BEC occurs when it is less than a few billionths of a degree above absolute zero.

This isn't true.

There are MANY forms of BEC. What you are referring to is BEC in atomic gas. But do not forget that a superconductor contains condensed cooper pair, which are composite bosons in a BEC. You also have superfluid He4 and He3 in a BEC, and those occur not at that low of a temperature either (certainly not a few billionths of a degree above absolute zero).

So the argument against the OP here isn't the "temperature" but rather the "mechanism" for such a formation.
