What is space?

[Arising_uk]

Please, don't be lazy. A short summary will do.

'Space' or 'SpaceTime' is the product of a 'crystalline' 'substance' undergoing Entropy and is the phase-change boundary between what it was and what its becoming. My best explanation of what Cerveny proposes.

OK, thanks, I'm seeing the interaction of ancients with questions about the universe an' all. I still don't get why we have a 'philosophy of science' which seems to me just to be asking questions which only scientists can answer. ...

Because many here don't understand what 'philosophy of science' is and keep posting questions that should be upon a Physics forum.

I should start a thread: 'What is the philosophy of science?' for dummies.

This is a good starter

Never said it nor implied space being solid. ...

You said 'science' said it was never empty presumably you agreed? ...

You're trying to twist my words. ...

No, just taking them at face value.

And how would you move through space and know you're moving through it? ...

Do fish know they are moving through water? Do you know you are moving through a fluid?

You're also confusing a fluid with space which are two different things.

How would you know as you say you don't know what space is?

Which of those fluid definitions you posted doesn't fit space?

Do I know that I'm moving through a fluid!!!? You seem to be bringing up the old aether theory which was discredited by the MM experiment over a century ago.

I didn't say I don't know what space is. What I'm saying is I don't know exactly what it is.

Thanks for that. Now I can breathe easy and get on with more pressing items.

Ah yes, of course...crystal clear. Hope Cerveny agrees with your summary.

In my travels on the internet over the past day, I've learned a reason for space not being empty is due to QM which makes sense which I'm making part of this thread. However there is more to the story than that.

PhilX

How does QM make sense?

QM says that any particle is nonlocalized and can be anywheres so that it can occupy any part of space which is why space isn't empty (there are other explanations on why space is never empty).

The question is simple, but the answer may not be. For example, in more recent times, scientists have been saying that space is never empty. We know that space can be modeled so that it gets bent and twisted by matter to create gravity. So I ask again, what is space?

I am lazy to explain it again, you can find most answers for your questions here: viewtopic.php?f=12&t=9654
sorry, if you have already read it

Please, don't be lazy. A short summary will do.

Thanks for trust, but as i can see present enthusiastic, naive physicists It would be rather contraproductive. But very briefly, for you:

-The History is a 4-D growing solid crystal of aether
-Elementary particles are structural defects there (see screw dislocaton, for ex.)
-"Now" is a last (only live),  just being condensed Planck time layer, quantum 3-D world
-The Future seems to be non-causal world of stem cells/elements, empire of ideas?!?!

next you can find in my story ....

Me:

What is space? The place between my ears where my brain cells are locked in unarmed combat.
Cerveny, I appreciate you providing that summary. Of course I understood some words.
Elementary ones like History, Now and the Future. Oh, and Empire of Ideas. But as to the stringing of all of them together...as an explanation for the nature of physical space...well,....

I love it.
I will slip it into a Hogmanay toast. When the time comes.
Way cooler than 'yesterday is history, tomorrow is a mystery, today is a gift, a present from...
I'm not making fun of you, honest. Just my embarrassed ignorance, not seeing what you do.
Cheers.

Do I know that I'm moving through a fluid!!!? You seem to be bringing up the old aether theory which was discredited by the MM experiment over a century ago.

What do you think the atmosphere is?

I didn't say I don't know what space is. What I'm saying is I don't know exactly what it is.

So 'What is space?' means what?

Try telling us what it's not exactly.

QM says that any particle is nonlocalized and can be anywheres so that it can occupy any part of space which is why space isn't empty (there are other explanations on why space is never empty).

No idea what 'non-localised' could mean as if it is a particle and it is somewhere then it must be local? And what about the bit of space that doesn't have a particle in it, is it empty or not?

If they are particles then what is the bit between them, space? If so then my definition appears pretty good, it's the stuff that a particle can move through.

You need to chat to uwot as apparently Einstein was happy with the idea of an 'aether' despite MM and I thin the idea is coming back in fashion in some form or other.

That's right. Your definition.

PhilX

[Arising_uk]

That's right. Your definition.

PhilX

And yours is?

[Philosophy Explorer]

That's right. Your definition.

PhilX

And yours is?

The exact or inexact one?

I'll wait on uwot.

You said you don't have an exact one so just give us what you've got.
