So.....we truly are 'circling the drain' then, eh?
Think of the universe as the surface of a balloon that is being inflated (in 4D ). So everything is moving apart from everything else. I'm not sure what the age of the oldest "light" we see is, but if the expansion fast enough then something too far away would take a long time to get somewhere that keeps getting further away.
I like your analogy, but not in its simplified form. If you look closely at the foam, some bubbles burst and cease to exist. Bubbles spread out over all the available surface until their volume to surface ratio leads to instability. String theory predicts a multiverse. Some possible universes will have physical laws that do not lead to long term stability. Some bubbles merge. This would lead to instabilities if the physical laws in them were incompatible. I'm not a proponent of the anthropic principle because I don't believe humans matter at all in this except as observers but I believe we are in a pretty unique place in an evolving but stable universe riding on the expanding bubble of another universe. The only interaction between our universe and that one is gravitationally. Evidently, one of the properties of matter in that other universe is mass. With the electromagnetic force not a common property, we have no "window" into the other bubble but we can surmise it's there.
I don't see black holes as portals to other bubbles. Black holes take in information but what becomes of it? I don't see it staying unaltered. A wave function must collapse at the event horizon. The big bang produced a quark/gluon plasma. Quarks and gluons and all other matter would have to be condensed into a singularity in a black hole.
None of this affects us in our time frame. Or if a wave from an incompatible bubble is headed our way, it doesn't affect us... YET.
Gotta leave now. This is the stuff of a good novel. Why am I wasting my time writing about it here? Don't anyone steal my crazy ideas. I got dibs. Time to start my novel.
every time we get a breakthough in astrophysics the questions keep mounting
here's one I have pondered ( I will keep it simple)
if the milky way has a radious of 105,7 million light years
and it takes 225 to 250 light years to for the sun to orbit the milkyway
if we could send a probe to rise above the milky way and scan down from above it and we looked back 112.5 to 125 light years back could we view the earth amd our solar system as it was 112.5 to 125 million light years ago on the other side of the galaxy?
you do realize human vision is faster than the speed of light
if at dusk on a clear night you face east and see the lowest star in the horizon then turnaround quickly and face west to the lowest star on the horizon you have viewed many trillions of light years ina single second "faster than the speed of light"
It's just modeled this way. The model doesn't pretend to say anything about the "actual reality" inside of there. It only makes predictions about what we'll observe over here on this side of the event horizon.
The earth is moving fast enough to not get caught and sucked in. The sun absolutely is powerful enough to suck the earth into itself, and things at much much greater distances too. The only thing is, it already did it to most of the stuff in the solar system that didn't have orbital velocity.
This is a version of the paradox where aiming a laser pointer into the sky and sweeping the beam between two stars that are a billion light-years apart from each other is said to prove that there's no faster-than-light limit. "See, the dot got from there to there in no time!" But all it really proves is that the signal from Earth might get to those two stars faster than any signal can get from one of those stars to the other.
You can't see past the event horizon because that's where the sausage is made.
No that is just relativity.
When I wake up at 3:00 I stick in the ear buds and listen to radio Gunsmoke.
I see it as more like looking at paintings or pictures. Speed of light applies.
Very well put for the common man to understand
. The Bing Bang in reverse. I won't bother saying anymore.
So go out and enjoy yourself, by THAT guitar , send the Mrs. shopping.
Believe me, it even kind of spooked me. I've spent a lot of time in the woods, no way I would go in a hole like that! A: Because I wouldn't fit. B: 'Cause I figure there would be at least one hundred and twenty seven rattle snakes living down there.
A sensible alternative plan you had there me lad, and much the better for you!
oh HELL no!!! I'm insanely claustrophobic. This is nightmare fuel. Thanks.
you guys realize I messin wit ya
I am content in the knowledge that mysteries exist .
I'm glad someone else ponders these things too. There are things we don't know or understand. It's like that tiny ant walking along on the sidewalk, as you walk over him everything ends for him. But he had no inkling you even existed. At the same time you had no idea he was there.
It's like if you went into space at the speed of light and came back....... the time wouldn't match. You might return to your gr gr gr gr grandkid's life.
