(G)Rave On

So, any theories on whether some of our universe's forces are truly (multi)universal?
If gravity is transdimensional, our universe may be globally attracted to others ?around? it, leading to a constant state of expansion, without the need for weak interacting dark matters.
This would seem to posit gravity as the strongest force of all; it seems diluted to us because we can't see all of it, as much of it is beyond our perception , in other dimensions...
In such a case, I guess the fabric of space would stretch, but still not really expand into any "thing".
If it becomes stretched unevenly, by more than one strong attractor, I wonder if our physics laws become physics guidelines...

The many worlds theory,

The dart..superposition and the probability wave (revisit)

Just a thought, If we are travelling in a probability wave and there are many outcomes (Schrödinger's EQ) then how many pasts are there?
If you could go into the past would there be many?
Many futures<>Many pasts? :scratch: Or would the past be the result of the collapsed wave function the actual outcome as opposed to the still existing probability wave?

Just a fun thought..😀

Are you in superposition before you are born or at what point after death?

The probability of you existing before you do?
The probability of you not existing before you do?

Is life force in superposition<<can something be alive and dead?

A ghost<<not a fan of that word but it portrays the idea..😀

Just a fun idea.

Just a thought,

If time travel was possible and the probability waves had collapsed would it mean you could visit the past but not be able to change it..or would it mean you couldn't visit the past because you can't change it..

Surly the only way you could change the now in the past is for the probability waves to still exist, or how else could you change the outcome assuming it isn't already set!
i.e. the idea of no free will?

If the probability waves still existed how could you change the future in any different way from living in the now<<<the outcomes could not be predicted all events would have to play out again?

Entropy...

If the universe is expanding are parts of the universe older?
The idea being the outermost "edge" should be older, if entropy was sending us into a big freeze then shouldn't the outermost regions already be in it? Reminds me of a fizzy drink the surface bubbling and everything disintegrating into the nothing..😀

Or is the whole universe like a hot drink created at the same time and cooling at the same rate though out...of course that would mean infinity is loosing energy so where is it going. Then again is infinity a closed system?

0 / 0 = ? sounds a bit like the universe.

Just a fun thought..

Wtf?

I've read somewhere, that the original protoparticle universe prior to the Big Bang was perfectly symmetrical.
If this were so, would the bang not also be perfectly symmetrical, resulting in an expanding sphere, with all matter and energy in an ever thinning "rind", surrounding a void at the epicentre of the original bang?
The observable fact of uneven distribution of matter seems to imply the explosion was off the centre, of an infinitely small protouniverse particle.
It seems strange to me that something infinitely compressed to a perfect super symmetry could have structure within, even if only enough to be off centre- this means even something unimaginably tiny must still have measurable dimensions within it, even though all of what we consider to be space was contained within it.
Unless all of the above is wrong, and the Big Bang perfect sphere blast pattern was affected by adjacent universe's gravity fields, which may be the only measurable evidence we can discover of these other universes.
Sure wish I have the math skills to really explore these ideas, I'm limited to imagining this stuff, literally, in images.
This has some strange effects at times- I sometimes drift for over an hour without noticing the time passing, and once when answering the phone, after being jarred out of imagine time, actually had some difficulty speaking clearly for the first few sentences.
Limited capacity, perhaps, but I tested, and can still walk and chew gum concurrently , to my relief!

Before the Big Bang

Another random thought- if everything was squeezed to one perfectly compressed point/source, there would be no frame of reference within it, so would that point/source's condition before its first motion best be described as both something and nothing?
