Wondering that was like a dog chasing it's tail. If there's nothing past everything that's expanding, what does nothing look like? Is it darkness without stars, planets, comets, asteroids, black holes and SiriusXM?

I have always wondered that. If the BBT is true and the universe is expanding, what is it expanding into? Is it into a bigger, different universe? It surely can't expand into nothing, right?
Maybe it is like that scene in MiB where something is playing marbles and our universe is one of them

Well, according to science, nothing is all that existed before the primordial atom that became our universe, but they obviously have no way of knowing.I have always wondered that.

I've always felt there must be other universes beyond ours....some gaseous, some fluidic, some mostly empty space, like ours....It's a world of possibilities.

You guys might be confusing the entire universe with the observable universe. The universe that we can observe from our home planet is about 46 billion light years in size, but we are talking spherical in size.
As far as what is at the end, well, it's quite possible that nothingness, or darkness, is exactly what the universe is expanding into. The question is, what is causing the expansion? Dark energy is what scientists think is causing it but we have no way of actually seeing it. The universe is expanding faster and faster too. Another question is what happens when the universe's energy is finally expended?
The big rip? Eventually, the speed of expansion will be so great that stars and planets themselves will be pushed apart and gravity will no longer be able to hold together our universe. The expansion will eventually get to be so fast that atomic forces will no longer be able to hold their constituent particles together since the space between them will be expanding so quickly. RIP!!!!
The big crunch? As the universe expands, eventually gravity will begin to take hold and force the universe to collapse on itself, pulling everything with it together until it eventually turns into the biggest black hole ever. CRUNCH!!!
I always liked to theorize that the big crunch could be part of an infinite cycle. The universe expands out until it collapses on itself and then it becomes so dense and hot in a singular point that it expands again. To an outside observer who measures time differently than the universe, it could just be like watching something just sit there and yo-yo in and out. haha

lol. Humans, including me, are crazy. There is no way our minds can wrap themselves around just how impossible large 46 billion light years could be. So, what do we do as an alternative? We try imagining what is BEYOND 46 billion light years. We humans rocks.

Here's the thing. Scientists haven't been observing the universe long enough to know if it speedster up and slows down, like waves, or if it's just expanding faster and faster. Frankly, they tend to get a lot of things wrong before getting all the information, so I'm not in the least concerned about how, or if the universe dies, billions of years from now.

Oh definitely scientists are going off of projections and in some cases speculation. Still, its impressive the knowledge we have gained. That is what is fun about the universe too. Everytime we think we've found a scientifically sound theory on something the universe will take a deuce on it. And yeah, time is nothing to the universe, but, even if it ended in an hour you probably would never know it. It would just be lights out.

Shooting stars can be low in the sky, and depending on the materials in the meteor, they can appear different colors.
I'd suspect is was a shooting star that broke up into pieces.
I'm open to the possibility of UFO's being "little green (gray?) men", but with this planet being on the edge of an average size galaxy in one of millions of galaxies, to me it's very unlikely.
Speaking of "little green men" we did a study at church on a book of just that title, very interesting book....
