Discussion Overview

The discussion revolves around the concept of motion and its relationship to space, questioning whether motion can be considered relative to space. Participants explore theoretical implications and the nature of space itself, with a focus on the ability to measure motion in relation to space.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants question why motion cannot be relative to space.
  • There is a query about how fast space is moving and how a spaceship could measure its speed relative to space.
  • One participant expresses uncertainty about the concept of space moving, suggesting that if space could move, there should be a way to detect it.
  • Another participant argues that since there is no way to detect the movement of space, it may not be a thing that moves.
  • Some participants express frustration over misinterpretations of their statements regarding the nature of space and its movement.

Areas of Agreement / Disagreement

Participants generally disagree on the nature of motion relative to space, with some asserting that motion cannot be relative to space while others question the very concept of space moving. The discussion remains unresolved.

Contextual Notes

Limitations include the lack of clarity on definitions of space and motion, as well as unresolved questions about the detectability of space's movement.

Why can't motion be relative to space?

How fast is space moving? I.e. a spaceship is sitting in space, how would it measure its speed relative to space?

I don't know how fast space is moving. I didn't even know that space could move.

You wouldn't be able to measure speed relative to space.
 
Exactly. That's why motion can't be relative to space. At least not in any scientifically useful sense.

So does space move? What is space?

If space is a thing which moves, surely there must be some way of detecting it.
 
So running your logic in reverse, since there is no way to detect its movement then surely it must not be a thing which moves.

How do you know space moves? What is space?

I never claimed that I do know this.

I am not comfortable continuing a conversation when you respond to every comment I make as though I had said the opposite of what I did. Thread closed.
