In the double slit experiment we see a single electron making a wave pattern, this shows us that the different dimensions/universes can interact with one another.

For what its worth, the reason that the little electron goes through only one slit whilst being percieved, i would guess, is because our universe exists only on one phase of light. This is why dark matter appears dark. Like having two bishops on a chess board, one black on black, one white on white, although they effect one another and move on the same board they cannot directly interact.

Please, for the sake of my family and friends, will somebody smart tell me im completely wrong?

There is not just a single frequency of light.

"Visible light" covers the frequencies from Violet to Red, and a combination of all these frequencies is perceived as white light.

Our instruments can detect a much broader range of frequencies from long radio waves to shorter micro waves and IR waves to visible light to UV light top gamma radiation. 

Some matter in interstellar space undoubtedly will be very cold, approaching a few degrees Kelvin, and will be difficult to detect.

What is the total mass of small ions in cosmic rays?

[yor_on]

Sort of nice idea Yadi

And quite poetic, I may lend it from you some day, if that's okay?
Not for Science as such. But wasn't it Heinlein that once said that any sufficiently advanced science may to the observer become indistinguishable from magic? And you're quite close to magic there. What you might want to argue is that there's a lot of invisible 'bosons' in particle physics, as the idea of a Higgs boson.

So

[Nizzle]

Maybe it's better to say "light in a different 'phase'" instead of different 'frequency', because, as CliffordK already stated, we already see a broad spectrum of frequency in our own universe..

Welcome to the forum.

will somebody smart tell me im completely wrong?

Probably, but it won't be me, as I'm not smart.

So you have electrons jumping from one universe to another, which are both in the same place? We can't see the other one, because its on a different wavelength. Well, as Clifford pointed out, we can't see light beyond our visible wavelengths, so are you suggesting that insects which see the same things as us but in ultraviolet, are invaders from another universe?

I'm afraid I can't buy into this idea of multiple universes. The universe is infinite, so I don't see how you can have two or more infinites.

[yor_on]

The problem is Don. A lot of serious physics seems to enjoy it
It gives me a headache too.

I'm afraid I can't buy into this idea of multiple universes. The universe is infinite, so I don't see how you can have two or more infinites.

Isn't the universe modelled to be spatially finite? Admittedly, it may be infinite in time however.
Just for clarity, as I (vaguely) understand it, multiple universe theories still point to a finite (if truly, unimaginably enormous) number of outcomes (universe wise). So infinities are potentially avoided  [] ... perhaps.

I wondered about the 'leaking' of mass from other universes too (and may even have popped up a question on it many moons ago). If memory serves, there was quite a compelling reason to indicate that it won't easily fit with the (gravitationally) observed 'clumping' in our universe (around galactic centres).  'Leaking' mass from many universes would (I think the argument goes) be more or less uniform throughout space.

  'Leaking' mass from many universes would (I think the argument goes) be more or less uniform throughout space.

I understand the logic their using but i expect it is wrong. The closer (more similar) our light phase is to the next one would determin the power of its gravitational effect. This would make it seem, no matter which light phase u were in, that your universe was being clumped together by the others.

[acecharly]

Dark matter is a hypothesis and doesnt exist yet as nobodys observed it.

One of physics theorys doesnt add up at the moment so scientists make up something to make their sums work.

So

Yeh safe man, its as much philosophy as it is science anyway... i did work out the meaning of life too if you'd care to hear it let me know!

[yor_on]

Give it a shot Yadi.
That's another of the unsolved mysteries to me

[peppercorn]

What is "light phase"?  I've never heard this term before, at least not w.r.t. multiple universes. [Sounds more like something to do with Oil Refining to me]

Edit:
oh I've just re-read the topic & think I see the idea, but it still seems a mighty big assumption that universes somehow 'next door' to each other would have even close similar very-large-scale structures.  How would the nearness (working back in time) make these universes more able to leak mass than any of the other googolplexes of universes.

[yadi999 (OP)]

Why wouldn't it be easier for the closer ones??

If were presuming some kind of stack of paper is our stack of universes, if you were to put a needle in it then it will only effect those pieces of paper it was long enough to touch. I would expect it would be more like gravity though, the closer it is the more of an effect it has.

[yor_on]

Well, I've seen the idea of 'bubble universes' coming from the Big Bang. Not one but a 'infinity' of universes, all with their own constants. Those like ours having life, others just 'dead' from slightly different constants. There one possible approach to prove such a behavior would be if two bubbles 'collided' creating what, to us, might look as a very distant but strong explosion. But as they then would be ? I don't know, that one hurts my head, thinking of 'dimensions'.

[peppercorn]

So you're suggesting that a universe that pealed off (an infinitesimally small time earlier) has a greater chance of being nearer (in terms of a higher spacial dimension) to our current perceived universe than any other.

This is an attractive idea, also, as it might lend an an explanation to where the 'largeness' of the mass we can see comes from as well as the dark mass we can't.

No it wouldn't - we don't see dark matter because it is stagnet to the EM forces. We only see matter because photons bounce off these objects that we can see, dark matter does not interact with radiation belonging to the EM field.

I meant (I thought obviously) that we only see DM's effects gravimetrically whereas we can detect 'normal' matter by EM as well.

We can call it energy in empty space, it is the Main reason behind star formation.
It collects hydrogen atoms in free space and compresses it to form helium and a lot of energy. This universe exists because of dark energy, including us

Not sure what you are getting at there Aks.   Dark energy is not a lot to do with free hydrogen - and only really linked to dark matter by a similar name.  Dark energy could have something to do with vacuum energy of space - but the maths is all wrong (10^120 times out) and it is not accepted theory by a long shot.

[maddyporter4639]

quantum theory, right? I think your completely wrong but you never know. I would doubt (if I'm understanding your question correctly) that all the unseen matter  of the alternate universe would be dark matter , or much more than 25% of the universe would be full of it.
