Plank length and what is between
Plank length and what is between
This is believed to be the shortest distance between two points in space so-called Plank length. What is between two points? It cannot be nothing since otherwise two points obviously coincide. Therefore, there is something between the two points. This means that space is a substance. Following the same logic, it follows that time also is a substance.

Re: Plank length and what is between
It could be "nothingness" in the sense of a vacuum where the closest possible particles would have spatial extension from each other that would be measured as a Planck length. Space isn't a substance in this case. It's merely a way of talking about extensional relations.

What is the vacuum? How does the vacuum if it is nothingness could have properties like vacuum constants?Terrapin Station wrote: ↑Mon Jan 25, 2021 1:19 am It could be "nothingness" in the sense of a vacuum where the closest possible particles would have spatial extension from each other that would be measured as a Planck length.

Re: Plank length and what is between
I mean where it wouldn't have any properties. Again, it would be nothingness, where the area is defined by objects "outside" of it, by their spatial extension.bahman wrote: ↑Mon Jan 25, 2021 1:37 amWhat is the vacuum?

Re: Plank length and what is between
You can safely remove it if it has not any property. That is true since something which does not have any property cannot affect anything.Terrapin Station wrote: ↑Mon Jan 25, 2021 2:24 amI mean where it wouldn't have any properties.

Moreover, another question that is valid is that if it is a vacuum, the minimum distance between two objects, then why it is that number and not any other number.

You'd not be able to remove it without affecting the extensional relation of the particles in question though.bahman wrote: ↑Mon Jan 25, 2021 2:58 amYou can safely remove it if it has not any property.

Re why that would be the minimum distance between particles, presumably it would be due to some sort of repulsive force of the particles.

Planck length is the minimum distance between two points in space. It is not a matter of having particles or not.Terrapin Station wrote: ↑Mon Jan 25, 2021 12:47 pmYou'd not be able to remove it without affecting the extensional relation of the particles in question though.bahman wrote: ↑Mon Jan 25, 2021 2:58 amYou can safely remove it if it has not any property.

Re: Plank length and what is between
In reality it can only be the minimum distance between particles. There are no real points.

Space deforms and carries information within the curvature. It is a substance.Terrapin Station wrote: ↑Mon Jan 25, 2021 10:32 pmIn reality it can only be the minimum distance between particles.

No, it isn't a substance. That view is incoherent ontologically.bahman wrote: ↑Mon Jan 25, 2021 10:47 pmSpace deforms and carries information within the curvature.

Re: Plank length and what is between
How would you say that that amounts to observing space as a substance?bahman wrote: ↑Mon Jan 25, 2021 11:03 pmGravitational wave was observed.Terrapin Station wrote: ↑Mon Jan 25, 2021 11:01 pmNo, it isn't a substance. That view is incoherent ontologically.
Re: Plank length and what is between
Space-time according to general relativity theory bends. This theory is confirmed experimentally, the last observation being the existence of gravitational waves. It is empirically proven that space is something that bends, carries information, therefore it is something. It has properties as I mentioned.Terrapin Station wrote: ↑Mon Jan 25, 2021 11:10 pmHow would you say that that amounts to observing space as a substance?bahman wrote: ↑Mon Jan 25, 2021 11:03 pmGravitational wave was observed.Terrapin Station wrote: ↑Mon Jan 25, 2021 11:01 pm

Do you not buy instrumentalism?
