Could you build a container to isolate cosmic radiation?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of constructing a container that could isolate cosmic radiation to achieve a temperature of 0 Kelvin, effectively halting atomic movement and, as a consequence, stopping time within that container. The conversation touches on theoretical and conceptual aspects of physics, particularly relating to temperature, atomic behavior, and the nature of time.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions the possibility of creating a container that could isolate cosmic radiation and achieve 0 Kelvin, suggesting that this would halt atomic movement and stop time.
  • Another participant points out the challenge of dealing with atoms already present in such a container and mentions that physicists have reached temperatures as low as 0.5 nK, indicating that achieving absolute zero is not feasible.
  • A participant proposes the idea of breaking up cosmic radiation particles into smaller particles that could pass through the container, while suggesting the use of denser materials to prevent them from re-entering.
  • Several participants clarify that reducing atomic activity does not equate to stopping time, emphasizing that time cannot be stopped.
  • One participant expresses concern that the original premise is based on a misunderstanding influenced by fictional sources, leading to a suggestion to seek out more reliable scientific literature.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of the original premise, with some clarifying misconceptions about time and atomic movement. The discussion remains unresolved regarding the practical aspects of isolating cosmic radiation and achieving 0 Kelvin.

Contextual Notes

The discussion highlights limitations in understanding the concepts of temperature, atomic behavior, and the nature of time, as well as the influence of fictional representations on scientific inquiries.

TL;DR
cosmic radiation blocker to stop time in the isolated area.
could you build a container to isolate cosmic radiation so that you could get it down to 0 kelvin, halt the movement of atoms, and make everything still in this box, (to my understanding) therefore stopping time in this isolated box? I'm not a scientist, I just watched steins gate.

Hello and :welcome: !

The difficulty is what to do with the atoms already in such a container. In the end, you ask about how to achieve an artificial environment with 0K. The internet says that physicists were able to achieve 0.5 nK (in 2003). Shielding alone wouldn't help.

Reducing or even halting atomic activity certainly does not stop time.
 
Would it be possible to break up the cosmic radiation particles into small enough particles that they could pass through the container with something attracting them on the outside and then put a denser material on the container so that they could not go back in? Sorry if this is a far-fetched question

Ah ok, thanks. I heard incorrectly.

No, although you can in principle get fairly close to. But then
(to my understanding) therefore stopping time in this isolated box?
No, because your understanding is wrong - time doesn’t “stop”. This might have something to do with
I just watched steins gate.
...which is fiction so cannot be taken seriously;
stuff like this is why we have the forum rule about acceptable sources.

As this thread is based on a misconception it is closed.

@JOHNTITOR1 If you are interested in this stuff (and I expect that you are or you wouldn't be posting here) you might want to find and study good non-fiction - textbooks, books and articles that people here recommend. It's more work than playing around with the oversimplified and dumbed-down pop-sci stuff that you'll find wandering around the internet, but it's one of the most worthwhile and rewarding things you can do.
