What is Space?

Could space be a sea of waves?

If space is nothing how can things move through nothing?

If space is something then what is it?

space is an area (volume) that makes things possible, including nothing, or very little.

it’s where possibilities exist, or might venture. Like this white rectangle i’m typing into.

It’s the final frontier.

reminded me there’s a star trek movie on tonight I haven’t seen

Good question :)

You’ll know all about it… when you run out of it

Yes, as Crispin said, we’ve covered this before.

As for waves – the Copenhagen interpretation of QM says that all of space-time is filled with probability waves. Probability waves contain no mass or energy.

If space isn’t nothing, then how can anything move through it without drag?

There’s no drag.

More on “sea of waves”.

QM tells us that every wave is a particle and vice versa.

There’s no drag.

If matter is standing waves in whatever space is, then matter would move through space without drag in the same way that electro-magnetic waves move through space without drag.

If space is nothing, how can it have a probability wave?

You ever noticed that the slice of reality you occupy at any moment is made from mostly the past (which doesn’t exist anymore), and a future that doesn’t exist yet (the possibility of a future).

Does anyone here actually claim that space is “nothing”?

a few are hunting it, wanting to interrogate it, not happy that a nothing between other things can have a function.

Lots of people do, here and elsewhere.

Or at least they seem to.

Tell them they’re dreaming.

There’s no such thing as nothing, but there is such a thing as space.

I’m not happy with our current understanding of space. Looking around for a list of properties of space turned up rather disappointing results.

No. I’ve noticed the exact opposite, that whereas the past and future can be said to exist, the present does not. It is very difficult for me to write in the present tense because even before I’ve finished writing a word it’s in the past. Everything that I write about is either the past or the future, never the present.

To add to that. In relativity, events that appear to be in the future for my right hand for instance can be in the past according to my right eye. Because right eye and right hand are different frames of reference. To put it another way, any event that is in the present for my hand will never be in the present for my eye, or for any other person.

>….. the present does not

yes, I was pointing to that
