Equation for the velocity of a closed universe.

Featured Replies

V1 = H0 + V0 / 𝛄

This is my equation for the increasing size of a closed universe. It is explaining that V1, or the velocity of the universe, is equal to V0, or the last velocity of the universe per second per megaparsec. The H0 is the Hubble constant, and the expansion of the universe. Gamma, is the Lorentz factor which is used in incorporating special relativity into the equation and using the laws of special relativity. I am open to criticism. Remember, this cannot be used on an open and infinite universe, it is only for a closed universe, which we do not know if our universe is or not.

The velocity of the universe would be the change in its position relative to something that isn't the universe. It really makes no sense for a universe to have a velocity.=

Velocity per second per megaparsec would be something like v/t/d (velocity, time, distance) which is d/t / t / d which is 1/t², something with different units than velocity at least.

As for special relativity, that only applies to flat Minkowskian spacetime with zero energy and mass anywhere. For this reason, it is simply inapplicable to our universe except locally.

Your equation adds values of different units, which makes it meaningless. You can't add meters to Pascals, and (in your case), you can't add H (units 1/t) to V/γ (units d/t)

Another criticism: γ is the Lorentz factor of what exactly?  It should be the factor for some speed, but "the Lorentz factor which is used in incorporating special relativity into the equation and using the laws of special relativity" is just a word salad.

(V1 = H0 + V0) / 𝛄

I got my order of operations wrong, does this work better?

Hold on, I think I got this now...

V1 = (227 * 10-18 + V0)/ 𝛄

Which happens every second

 

or this

V1 = ((227e-18 + V0) / 𝛄) / s

Never mind, loopholes. Scratch that

V1 = ((227e-18 + V0) / 𝛄) * s
Do this instead

The recession velocity of the farthest galaxies exceed the speed of light so your equation must be wrong since your equation 'blows-up" if v=c.

When you are talking about v, are you talking about V, or v (Volume or velocity). Because if v is velocity, than the only time v shows up is in the Lorentz factor, which is the speed of the observer. The 227e-18 is just an approximation of the speed of the expansion of the universe in m/s (meters per second). I don't know. I am up for criticism

Every use of 'v' in your equation is velocity so I am not sure why you think I would be talking about a volume.

Did you forget that V1 and V2 are also velocities?  When you say "speed of the observer", what is the speed is relative to?

Hold on, I thought that V was volume. Anyways, I can change it.

m1= ((227e-18 + m0) / 𝛄) * s

When I say "Speed of the observer" I mean it is relative to the universe. Basically, why I added 𝛄 into there is because of length contraction. Because of length contraction, the universe should appear smaller to you, or at least things should appear closer to you. So when I say that, I mean relative to the universe's size, or just the universe as a whole.

Hold on... I looked at the equations and V should be volume. Unless you do m (meters)

but m is mass so idk

You clearly identify it as velocity in your first post

V1 = ((227e-18 + V0) / 𝛄) * s 

This is my equation for the increasing Volume of the universe. V1 is the Current Volume of the universe. V0 is the Last Volume of the universe. 227e-18 is the approximation of the Hubble Constant in m/s. 𝛄 is the Lorentz factor. This incorporates things like length contraction. s is the number of seconds.

My brain did not brain, I am sorry.

And I have improved it again

V1 = ((227e-18 + V0) * s) / 𝛄

You haven't improved anything your just spouting random WAGs that pop into your head.  It's just a waste of time, good bye.
