Discussion Overview

The discussion revolves around the nature of matter, space, and time, particularly in the context of movement and entropy. Participants explore theoretical implications of these concepts, questioning whether space and time can exist without movement and what happens at maximum entropy.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that the concept of everything being composed of smaller parts is a human-made idea, proposing instead that everything might be movement in space.
  • Another participant raises the question of whether space would still exist if the universe had no mass.
  • A participant mentions an experiment involving cooling atoms with lasers, leading to a discussion about Bose-Einstein Condensates.
  • Some participants express uncertainty about the existence of space at maximum entropy, with one questioning if space would cease to exist under those conditions.
  • Another participant argues that space is merely a measure of disorder and should still exist even at maximum entropy.
  • There is a mention of the Heisenberg Uncertainty Principle (HUP) suggesting that matter and residual heat would still be present despite changes in movement.

Areas of Agreement / Disagreement

Participants express differing views on the existence of space and time in relation to movement and entropy. There is no consensus on whether space would cease to exist at maximum entropy, and the discussion remains unresolved.

Contextual Notes

Participants rely on various assumptions about the nature of movement, entropy, and the definitions of space and time, which are not fully explored or agreed upon.

My knowledge about physics is rather limited, so I would appreciate if you could set this straight.

I just made an assumption that the concept of everything consists of smaller parts at different levels is a man made concept that derives from what feels natural in our day to day perception of things. What if everything is in fact movement in space and nothing else.

And then we know that if movement is present, space and time is the result of it for it to be able to happen. And that led me to think that if there is no movement in space happening both space and time sieze to exist.

So if: distance (space) = speed x time it would mean that if the entropi of the universe gets at its ultimate peak and all movement sieze to exist, both time and distance sieze to exist forcing everything into one point, sort of a big bang scenario?
 
Physics news on Phys.org
There have been hypotheses put forth questioning whether, if the universe had no mass, would space still exist?
 
Ive heard that there was an experiment of cooling down an atom with lasers until it disappeared and then reapeared. Interesting.

Are you referring to Bose-Einstein Condensates?
 
According to the currently accepted models in mainstream science, matter, space, distance and time exist.

Dont really know since I can't really find any source to it. But what I am thinking about will space still exist when the maximal level of entropi will be reached?
 
why would space not exist when max entropy is reached. It is just a measure of disorder in a system

Well, Is making an assumption that everything that moves generate heat, and slows down right?
 
But matter would still exist, and there would still be residual heat due to HUP
