Can a vacuum be stretched?

Featured Replies

If I put a hydrogen atom with its proton directly between two equal black holes but at a distance that allowed it to keep its electron, wouldn't the orbit be eliptical and vacuum or space stretched on the line between the black holes?

fine on paper, but then how would you restrain your "black holes" from each others feild if it has such an effect on a Hydrogen atom in the center? :))

Like binary star systems it would take a balanced stable spin of the two black holes around each other to have a fun gravity lab to play with in the middle. I'm just using intuitive logic which often sounds good but is often wrong.

Still it seems logical that absolute space or vacuum would seem to be effected by extreme gravity.

A proof might be to see if light rays bent by gravity effects and travelling over a greater than direct distance arrived with a delay. That would show space was stretched since the speed of light is constant.

What's your problem with paper?

 

hmm... I think he means that this is all in theory. I am not really sure though!

Yeah, I know that.

 

I don't see why it's a problem.

I don't think there really is a problem with 'imagining' something. If there was, then, there would already be problems here:

1.How to make a perfect vacuum

2.You to contain the vacuum

3. how to then stretch it

etc.

Well my point is that seeing as the only absolute vacuum we in this thread know of is imaginary (unless you count intra-atomic spaces), the fact that this is all "on paper" is somewhat inferred by the fact that we're discussing it at all.

yeah. I totally agree. I think that YT is trying to tell us what would happen if this is to be put in reality. A different effect.

ok guys! This is what he says:

 

According to scientists, you can stretch atoms. There are some atoms in a vacuum, a very few, but there are a few. SO, you can stretch those, you stretch the vacumm.

 

Well guys?

that`s all cool, but you`re actualy stretching atoms and not the vacuum, and a vacuum with atoms in it is just a low pressure area in containment.

AOM, yeah, you`re quite right, it was meant on paper (theory) as opposed to in Reality :)

ok. So just tell him that it is not a vaccuum anymore, but an area of low pressure? That seems good enough!

Which scientists are saying you can stretch atoms?

 

A vacuum isn't an entity. It's the absence of something. How do you stretch something that isn't there?

If you have a bellows with its end plugged floating in the vacuum of space, couldn't you expand itand stretch the space inside it using virtually no force. The same should apply to a sealed syringe in space. It should take virtually no effort to pull the syringe back since the vacuum inside would equal the zero pressure outside.. Just a couple intuitive exercises.

That was EXACTLY what i was telling him!

The idea of ripping space is like saying black holes are wormholes.Can you cut space with scissors? NO... the vacuum just surrounds it. Stretching the vacuum around objects is obviously possible, but every square cm.of empty space is a constant vacuum. There can only be a higher pressure than the lowest possible, therefore a rip is impossible. A natural equilibrium relies on lower pressure to recycle a balance. High pressure will swallow any amount of low pressure that is required to equalise the surrounding space perfectly. This is a unique unchanging feature of all space.

The vacuum only exists because it has a name,it has no beginning, middle, edge or end. Do people really believe that free space can be stretched, it moves as wind, varying areas of pressure but still leaves a vacuum.
