And it is getting bigger. One of the more popular theories of an expanding universe is that it is not so much things are rushing away from us. It is that there is more space being created between things.
This explains how I managed to miss what appeared to be an easy shot at a decoying Canada Goose last year.

Hubble ultra deep field view. This covers an amount of sky equal to holding a grain of sand at arms length, and it's apart of the sky that was previously thought to be pretty empty. Pretty much every dot of light in the picture is its own galaxy, and each of those galaxies has within it billions and billions of stars. Amazing.
Anyway, the little red dots in the pic are extremely distant galaxies, they appear red because of redshift. They aren't actually red, but their light gets stretched by the expansion of the universe and shifts towards the red end of the spectrum. Being super-distant, they're also super old.
I love astronomy and have always found it so fascinating that a lot of it is almost to the point of being unbelievable. And this picture is a great example of treading the line between believable and unbelievable.
According to the Big Bang theory, a man made theory along with all the other man-made theories and observations of deep space with distances so vast that human minds can't comprehend- the universe started when a singularity suddenly burst open. A singularity is thought to be a speck of pure energy smaller than an atom. So when this speck smaller than an atom burst open, it released EVERYTHING, all the substance that would end up making everything in existence. Matter can neither be created nor destroyed, new matter isn't being created and this has always been the case since the big bang. Matter can change forms, but it cannot be created after being released from the singularity. Everything that ever was, is, and will be was released when that speck of energy exploded.
So when I look at pictures like this and I think all these billions of galaxies, each with their billions of stars, with each star having its own system of planets, asteroids, and other debris orbiting it, that's an unfathomably large load of physical, tangible material.
So just think of the earth and compress that down into a space smaller than an atom. Compress our solar system down into that size. Next compress our Milky way galaxy with its 100s of millions of stars into that space. And then compress the billions upon billions of galaxies with their own 100s of millions to billions of stars into that space, and so on. I just can't buy into that.
To me, that idea is a heck of a lot more implausible than to the idea of a sentinent and perfect God being the creator of everything.
All these theories of the universe are thought up by men (and women). People who only have an actual understanding of time and distances in Earth terms. People who are imperfect as we all are. There is plenty of error in there somewhere.

If space is expanding, what is it expanding into? It can’t be dark since dark is something. If it is nothing what is nothing? It seems that nothing has to be something. Very confusing.

and THOSE theories are done without complete understanding
Look at the anthropogenic global warming alarmists. They sounded the alarm with cries of "Existential Threat!" with complete conviction that their story was the only believable narrative.

Space is expanding, according to the BB theory, because the explosion is still ongoing. Think of an m80 fire cracker, the blast starts at the firecracker and radiates out. That's what the very, very edge of space is thought to be. The outter radius of that blast? Buts what's beyond it? I don't know... I don't believe in the big bang
Then there's the corresponding theory I saw mentioned earlier of space contracting back down into the singularity in a theory called "The Big Crunch". Space will eventually compress back down into the singularity and then explode again into another Big Bang and that this is a never ending cycle of expanding and contracting like the rise and fall of your chest as you breathe and that there have been many universes before ours, and will be many after ours.
Sounds reasonable right?

So it can be infinity which leads to the basic question what started the first universe.

But most scientists believe that observations don't support the "Big Crunch" theory, because the rate of expansion that we observe is actually accelerating, not slowing.

so, if a black hole is so dense that nothing (not even light) can escape its gravitational pull...how can a singularity (with a nearly infinite amount of mass) overcome its own gravity to explode?

That's an interesting and valid question. I do not believe in the Big Bang. But if I was to attempt to answer your question, my best response would be that a singularity is a state of energy that has never been observed so the properties and physics of it all are just hypothesized. I would say there was so much mass and energy built up and vying to escape that instability occured like in a volatile chemical reaction, and it just exploded.
But what caused the instability? What created the singularity? Although I believe in God creating everything in existence, there is still the possibility that the Big Bang is an accurate representation of how everything came to be, and that God created the singularity and that God created the instability.
I don't put a lot of stock into all the specifics though as I don't think it has any determination on where I end up when my time comes

so if things only change fourm do we really die or just transform into an energy type being that can now move and travel without the bond that hold us in our physical fourm. Jesus was said to have a glow and God can not be looked at directly or it will kill us. Always referencing the light.
Just random thought.

Or the singularity was and is God's essence, but since he's infinite, the universe actually cannot be destroyed because it's not just what we can observe (so far) ...there's another reality behind this one that our senses can't see, but we know it exists because we can't seem to stop worshipping the something that we somehow know is real.
Right now I’m having amnesia and déjà vu at the same time. I think I’ve forgotten this before.

All great questions that should be directed to Dr. Michio Kaku on that science show on Hystory or Discovery channel. He’ll think they’re from a bunch of elementary students……lol
