Do black holes REALLY REALLY exist?
Is there any proof that other dimensions exist?
Finally, is there an edge to the universe?
I'm glad to see that I'm getting your son interested!
Answer 1: Yes, they exist, if by exist you mean that there's mass in the area where a Black Hole is said to be. If you mean exist as in... well..
EXIST. That'd up to debate. I'd have to say yes, they exist. I'd say that it's matter brought down to its very basic element (whatever that is),
and there is NO space inbetween these carriers of mass.
Answer 2: Depends what you mean. If you mean dimensions as in alternate universes, then no. The closest thing would be the photo-electron effect,
where electrons behave like light. The classic experiment with light is to set up a light source, then a thin slit for light to come through, then an
open area, then two more slits for light, then another open area, then a wall. You'll notice that the light forms "bars" of:
I_I_I_I_I (where "I" is illuminated, and "_" is dark)
They did the same thing with electrons, shooting them out one at a time. Odd things began to happen as it formed the same pattern, which meant that
SOMEHOW the electrons were acting like a wave, which is impossible since they're matter and were being sent through the "slit" one by one, and so
couldn't tell where the other electrons were going.
The proposed theory is that the electrons (remember that they shift into another spatial dimension when they go between orbits) were interacting with
electrons from other alternate universes, where the electron went through another slit. The average is what appears at the end, which is why it looks
like it behaved as a wave.
Now, if you mean other spatial dimensions, then the electrons changing orbits is the best proof we have of this, but space-time could also be said to
be an effect of this. So, yes.
Answer 3: According to most astronomers and theorists, no. Here's why.
Take a basketball. Draw a dot on it. This dot represents your placement in the universe. If you then draw a line from that dot in any direction on the
ball, you will never reach an edge. You'll just keep circling the basketball.
If the 4th spatial dimension indeed exists as it is believed to, then the same thing happens in our universe, except that it's a strange kind of 4-d
sphere that we could circle an infinite number of times without coming to an edge. This is also why there's no center to our universe - because it
doesn't exist in 3-dimensional space.
Here's my theory:
The "center" of the universe is the Big Bang - the point from which it all began. We are living in but one of a near-infinite number of universes,
where different chaotic events (events with no predictable outcome) occur in each one. Our universe is but part of this grand supra-verse. It is
because of this connection that so many things which are thought to be impossible sometimes happen.
For example, have you ever had a dream which then came true?
It's happened to me many times (though with much less regularity now), and has helped me to avoid arguments and dilemmas.
So, on one hand I said to myself, there must be Fate - since how could I know what would happen (often of places and people I had never met at the
time of the dream - roughly 6 months before the event)? But then, there couldn't be Fate, because I would change what would happen in my dream, and
what happened in real life (due to my interjection... before this it became so bad that I used to say "Man, I'm having Deja-Vu" whilst in my dream
before the Deja-Vu).
Now I believe that my soul (many more theories have I on that) travelled to another quantum universe which was exceedingly similar, but not entirely,
like my own. Since it was another "me's" universe, it was not fate, but instead what was simply likely to happen. Whether I let it happen that way
or not was up to me, since my future in THIS universe is not yet determined.
