Multiverse/Infinite universe

[Sorcerer]

No need for any "first cause" arguments here, just discussion of the many ways there could be a multiverse.

 

The Universe that was always expanding

 

Space is now expanding at and accelerating rate (cf dark energy)

If we extrapolate backwards, we could conclude there was a big bang.

If we observe, we can only see signs of inflation from just after this moment (cf Inflation theory, cosmic microwave background radiation CMBR.)

 

Therefore we cannot say for certain there was a big bang.

So it's equally possible that the universe's default state is inflation.

 

Matter and energy are fueled/produced by the expansion of space:

 

Space produces virtual particles (VP) (cf uncertainty principle)

As the volume of space increases the probability that more VP's will be produced increases.

 

When space is in its default state of inflation every frame of reference is receeding away from another at faster than the speed of light.

 

Virtual particles appear in pairs which cancel each other out and provide extactly the same ammount of energy that was used to produce them. E.g. Matter/anti-matter pairs.

 

When inflation is in process:

 

The probability of an anti particle pair increases as space inflates

The likelyhood they will "annihilate" decreases as space expansion (from their reference frame) approaches the speed of light.

The seperated pairs energy, which allows for their existence (E=Mc^2) is then deducted from the energy that is producing inflation.

 

So, inflation produces a tempory "swarm" of virutal paricles:

many annihilate and produce a large ammount of photons - these reduce the energy inflation contains (inflation reduction) and contribute to the CMBR

Some don't annihilate and remain till now - many bosons and mesons are produced - they are seperated by the faster than light expansion - inflation reduction

Due to an assymetry the majority of the anti-particles decay first = more energy into photons = inflation reduction

 

Inflation reached an equilibrium; with the matter/energy it produced and the gravity this mass then provided, and its initial energy.

This is the start of our universe we can observe (cf hubble volume).

 

___________________________________________

 

'exotic' matter (cf dark matter) is produced during inflation

during its lifetime it acts via gravity as a buffer to inflation and produces 'seeds' for galaxys.

It gradually decays and its energy is given back to increase inflation

The rate of decay is proportional to the rate of increase in expansion (dark energy)

Space is now expanding at and accelrating rate (cf dark energy)

If we extrapolate forwards, we could conclude there will be a big rip.

That is the default state of the universe.

Ok, here is my hobby horse idea...

 

 

The expansion of space time occurred in two different time directions, anti matter went backwards in time from our perspective and matter went forward but to the anti matter universe their time goes forward and we go backward.... in my idea there is no Multiverse unless there is another time axis we are unaware of....

IMO, there is no need for a multiverse. When two (or more) different outcomes are possible, a superposition is created within our universe, which gets resolved at some future time.

Ok, need isn't really a reason for something to exist, who's need? Yours? (sorry for being pendantic )

 

I see you are trying to use the copehagen interpretation of quantum mechanics to refute the many worlds interpretation. My multiverse is independant of both, it is a multiverse over vast ammounts of time, rather than one within moments of time (planck time).
