Executive summary: objects can't move faster than the speed of light, but spacetime itself can expand faster than the speed of light, and does, or at least it did in the early part of time just after the bang.
Also points out that, just because our view of something indicates it's many billions of years away, that doesn't mean it's actually there right now.
I’m not sure what that proves. There are objects in the universe that are many orders of magnitude more dense than osmium, which is still mostly empty space. A spoonful of neutron star “stuff” would have roughly the mass of the earth.
Climate change, of course. (Someone had to say it)
I have wondered about such things.
If you could somehow get in a spaceship and fly to the edge of the universe, what’s on the other side of that edge?
It was an intellectual exercise. I wasn’t out to prove anything. I just wanted to know how big a cube, that had all the matter of the universe, would be if it was as dense as the most dense element that we know of.
it is... good catch...
how amazingly unlikely is your birth. and pray that there’s intelligent life somewhere up in space, cause there’s bugger all down here on earth.
If you could go to the very edge of the universe, what’s on the other side that it’s expanding in to?
And, in theory, just disproved the BBT.
Orthodoxy has no place in science, but that’s what universities teach, and it extends literally to nearly every branch of science, including astrophysics.
I label it LCA, or ‘limited cerebral ability’...a condition overwhelmingly prompted by groupthink.
And IMHO it applies directly to the ‘BBT’.
“Follow the science” beyond the edge of the universe.
Lol.
Good post.
“Science” tells us a lot about human beings—and a lot less than we think about the “real world”.
I recommend books by Brian Greene, and, Paul Halpern. They both have books on this topic.
What is really mind boggling is that the signs all point to things keeping going until the heat death of the universe at more that 1 Trillion years in the future.
THEN Quantum Mechanics kicks in and who knows WHAT will happen.
This is addressed in virtually every physics course dealing with the big bang and the rapid expansion (inflationary period) that immediately followed. It takes a bit of reading, and some thinking. There are still many questions on the current theory - we’ve got a lot of work to do there. It’s far better to devote time to the N lies (where N is a very large number) dealing with climate change, CO2, etc. Going the woke route on climate change WILL lead to disaster. Not even close to kidding.
Might I recommend some visual aid, indeed there are more questions than answers as you come to realize that the more you know the more you don’t know.
Go to youtube and ‘favorite’ (that way searches pop up automatically) Kosmo, SEA, (especially) and Astrum for starters - there are many others that are excellent also too numerous to mention. If you don’t have a big screen TV you’re gonna want one!
Also do a search for the JWST (James Webb Space Telescope) and see some of the new findings, staggering discoveries that are turning astronomy and astrophysics on their heads.
Scientists thunk the speed of light has slowed down (also they have managed to slow the speed in tests)

Here is one that has always stumped me.
Lets say two space ships leave Earth at the same time but going in opposite directions. Each ship accelerates to nearly the speed of light (as close as relativity will allow) and goes for one year. From the perspective on Earth, each ship is going close to the speed of light, but in opposite directions.
Because nothing can go faster than the speed of light relative to anything else, from the perspective of each ship they are going close to the speed of light away from the other ship and much less than that away from Earth. So from Earth, each ship is moving away at the speed of light, but from each ship Earth is moving away much slower than the speed.of light.
After one year, both ships stop. From Earth, each ship is one light year away. From each ship, Earth is less than one light year away and the other ship is one light year away, because the other ship could not have moved further from them than one light year in one year.
Now let’s really complicate it by throwing in relativistic time dilation. Since each ship was going at close to the speed of light, time moved slower for them. During the one year that passed on Earth, only a few months passed on each ship (depending on how close to the speed of light they were going). So from their perspective, the other ship could be no further than a few light months away and Earth much less.
Rupert Sheldrake has been ragging on the scientific community for decades—among his arguments is that the “constants” of physics are not in fact constant.
Here is a brief discussion of this and similar issues:

Now take the musings in this thread and apply it to ‘covid-19’.
There was a post this morning about what makes us ‘eyeroll’...
For me, the virus/faux-vax argued by a lefty is still #1.
