Properties of Space

Ive updated my list of properties of space I’m not sure about number 24. If its wrong I’d like to know.

1 Space was created by the big bang, the universe is still expanding, so new space is presumably being created.

2 Space is transparent.

3 Space is also dark. Appears to have no color.

4 Space exists within the universe.

5 Space could be either Infinite or finite.

6 Space can contain things from atomic particles to galaxies.

7 Space has a relationship with Time, Space / Time.

8 Space is three dimensional or 4 dimensional with time.

8 Every point in space can support different vibrations across the frequency spectrum.

9 Objects like galaxies or stars can move around in space.

10 Space can carry high energy particles, radio waves and light, electromagnetic energy, gravity, weak and strong forces .

11 Space can have different objects like atomic particles or black holes that exist in different places that have different gravities which can attract or repel.

12 Space has a temperature.

13 Space can have structure. Space-Time gets curved by the mass of Stars and Black-holes.

14 Universe topology Flat, (No curvature, Open (Negative curvature), Closed (Positive curvature).

15 Space can be bounded or unbounded, assuming a finite universe, the universe can either have an edge or no edge.

16 Connectivity, how the universe is put together, simply connected space or multiply connected space.

17 Space has an impedance, Impedance of Free space.

18 Space can have high densities such as the interior of a black hole, star, or a planet with an an atmosphere to low densities such as a gas cloud in space or a vacuum in space.

19 The universe does expand faster than the speed of light, and some of the galaxies we can see right now are currently moving away from us faster than the speed of light.

20 Space could either be quantum foam, cosmic strings, quanta, nothing, another state of matter, or something different again.

21 Higgs energy field, If two particles exist in the higgs energy field (space) then it makes sense that if there is any entanglement, the two particles are communicating their characteristics through the higgs energy field.

21 Dark energy appears to be accelerating space.

22 Space itself is a property of space.

23 Plank Limit – Smallest point is space is defined by the Plank Limit.

24 Curvature of space, largest diameter of expanding space is defined as the curvature of space?

24 is wrong.

Or sort of wrong.

Or right.

Hmm. Perhaps I need to think some more about this. It certainly doesn’t address the case of where the curvature is negative. Because a negatively curved space has an infinite radius, not a negative radius.

According to wikipedia, the curvature of space is not the same as the curvature of space-time.

> 15 Space can be bounded or unbounded, assuming a finite universe, the universe can either have an edge or no edge.

Don’t assume a finite universe, this holds for both finite and infinite universes. So the correct wording is.

15 Space can be bounded or unbounded, the universe can either have an edge, multiple edges or no edge.

> 21 Higgs energy field, If two particles exist in the higgs energy field (space) then it makes sense that if there is any entanglement, the two particles are communicating their characteristics through the higgs energy field.

Um, you may have to think some more about that one. I don’t think that the Higgs has anything to do with quantum entanglement.

Perhaps two more from me, the next two are really two ways of saying the same thing.

25 The probability wave of Schrödinger fills the whole of space.

26 Every particle in travelling from a point to a nearby point passes through every point in space in its journey.

The following comes from a cosmology course I attended.

27 Every space has a metric.

Eg. The metric of Minkowski space is x^2+y^2+z^2-c^2*t^2

You probably also want to say something about space being the sum total of geodesics.

Thanks for the suggestions.

Space is metastable. Some time in the future it will catastrophically change into something unrecognisable.

Didn’t that happen before?

I think it did. But I can’t prove it.

That’d be singularitarly difficult…

Yep. All are correct. Well done. You’ve defined the space between my ears perfectly. :)

It’ll go blind if it keeps doing that.
