It’s quite the conundrum for sure. It seems the expansion model has some flaws that need to be worked out and even when we think we have it right I’m not sure we will. What I do know is we have lots of super massive blackholes, white drawfs and so on. Those black holes are only going to continue to get more massive and we have some that are eating up other black holes. These super massive objects pull on the fabric of space which in theory pulls some of it back towards them. Anyways my theory is that over a large amount of cosmic time these super dense objects are only going to get more and more dense and at some point will actually pull the universe back closer together and they will simply keep gobbling up all matter in all forms until they cannot become any more dense than they are and boom, Big Bang again. And I believe personally that it’s such a perfect machine that it will simply start itself over and over and over. Of course it might be billions and billions of years before this happens, but that’s my theory. Always has been since I was a kid. I’m just bit a scientist and I can’t prove it. But I’m super interested in this stuff.
Some believe that there also isn’t one universe but a multiverse if you will and that one spawns another until there is basically an infinite number of them. Crazy. But yeah, I’d say if there was an alien life form that has figured this, which is entirely possible, that they have a much better understanding of physics than we do. You’d literally have to be able to somehow warp space time to be able to travel the distances we are talking and I don’t know why any civilization that could do that either, A wouldn’t touch down a d chat with us, or B just obliterate us because they totally could.
Another interesting theory is that what we are seeing isn’t aliens, but actually us, from a future time coming to check on ourselves. And yet another theory says there is a group of beings called the watchers that are like angels that are supposed to watch over us but not become involved directly with us. This would make some sense considering they have been known to interact and disable nuclear weapons and such, supposedly. The idea is that they were asleep back in the day, not like literally but that they missed our use of nukes and don’t want to allow that again. Who knows. There are some crazy ideas out there. But what I find interesting is that it isn’t just our government seeing or interested in these things. As I said earlier Italy claims to have actually had one of their helos downed by one of these things.
also interesting is that literally every world religion has their own form of a creation and flood story. I also believe the earth is much older than we are told. Ok I’ve rambled enough.
