It was explained to me by this analogy:

Does it explain how an infinite universe could expand? It's this kind of science that makes no sense to me.
Take an infinite sequence of numbers, multiples of 2:
2, 4, 6, 8.....and so on to infinity
Now insert between each of those numbers the odd numbers,(kind of like adding space between the galaxies):
1, 2, 3, 4, 5, 6, 7, 8......and so on to infinity
So both are infinite, but the second infinity has "expanded" to include twice as much in it. It's obviously not even intended to be a perfect analogy, just to illustrate a concept that infinities can get larger and include more stuff, like empty space in the case of the expanding universe.
Our brains didn't evolve to grapple with concepts like these so it's not easy.
If it makes you feel better, here's Michio Kaku's explanation. He says we are sort of like an ant that's walking along the surface of a giant hot air balloon which is round, but the ant is so small and the balloon is so large that the ant can't tell the surface he's walking on is curved...it looks "flat" to the ant. Likewise, the universe looks "flat" to us, but Kaku thinks that like the ant's perspective, our perspective only makes us think the universe is flat, but it may be just really big like the hot air balloon is to the ant. At least that way you don't have to deal with the concept of infinity, but if it's not infinite then you still have the question of "what is "outside" if there is such a thing, which there may not be and that too is mind boggling. So there probably isn't an explanation that's not mind boggling.
Either infinite, or really big. If you think it has excluded the latter, you don't understand the latest science.

According to the latest science, it suggest that the Universe is infinite.

Expansion of the infinite is the concept in question here.
I don't pretend to know what caused the big bang. I've read some ideas on that but so far I don't think any are "proven". If quantum mechanics taught us one thing, it's that our logic which applied so well to the classical universe fails at the quantum level and thus we can't use logic to predict how the universe should or shouldn't be according to logic.

It cant be really big, if it was it would be finite. How could the Universe just appear one day from nothing? Nothing appears from nothing.
We consider the energy of the Universe, from the pseudo-tensor point of view (Berman, M.Sc. thesis, 1981). We find zero values, when the calculations are well-done. The doubts concerning this subject are clarified, with the novel idea that the justification for the calculation lies in the association of the equivalence principle, with the nature of co-motional observers, as demanded in Cosmology. In Sect. 4, we give a novel calculation for the zero-total energy result.

Well consider that within every atom is a singularity and we may be in a singularity even now.
CERN has found black holes within atoms. . . .
It could be black holes within black holes ad infinitum.
Theres supposed to be a supermassive black hole in the center of our galaxy, we could be in it already and just not know it.

See this is the science mythology I'm talking about.
You should source your information first to see if you're just quoting BS.
What I found was this:
" Micro black holes,......are hypothetical tiny black holes," Wiki
"Still, conventional physics suggest it would take a quadrillion, or a million-billion, times more energy to form a microscopic black hole than the Large Hadron Collider is capable of, so even a third of that is beyond human reach. Scenarios based on extra dimensions could have black holes form at a lower energy, "but they make no concrete predictions on what it should be," Pretorius said."
This is all hypothetical stuff science websites make articles about to get readers. It's really important to understand that all media is mostly about making money. Even if the owners and authors are passionate about the subject they need cash to finance their business and they have to make money to survive. Every day science websites put articles in the physics section that practically say "Quantum Computers are Complete and will ship in 6 months!!"
But we are not that far at all on quantum computers.
Nothing in the hypothesis says mini black holes are inside atoms though??
But the macro black hole in galaxy centers is a real thing. I don't know why we would be inside it though?

The thought that I had with regards to that, considering the assumed age of the Universe, and the fact that their are so many black holes at the centre of these galaxies. Then shouldn't we all be inside black holes by now. Safely tucked up in a place outside of the real and violent cosmos, outside of time, so to speak.

The observations of the physical Universe, require us to process the information in a spatial way, along with the dimensions to make any sense, time has to be in the equation . But when we consider our minds and the way they behave, we seem to be outside the constraining rules of the Cosmos. So the conclusion would be that when minds are free of the physical Universe, if this is the case then we are free of time and spatial considerations. Which seem to be the case, with regards to altered states.

Yes and if you consider dream states, they seem parallel but not quite the same as the linear experience. Then when the dream becomes lucid their is no difference in the feeling that you are on the cusp of the "Here and now" but the environment is different to the waking one. Which could be in fact a parallel reality. It seems that the mind can also experience the "day to day" from one of the altered states as well. Which makes me think that the "Day to day" is a lucid state, and is accepted as the main reality only because we require it to be so.

LOLz by crashing particles together they see the micro black holes appear for an instant. . . Why? Because they were there the whole time, this was found while they were looking for the Higs Boson.
Its just another aspect of a truly infinate universe.
As to superposition, just think of the BIG BANG/Singularity everywhere in everything at point in every time.

I get the inversely proportional square law. Its a bit of a coincidence that the solar systems planets have all settled into stable orbits. Their seems to be a lot of handy coincidences when you look at the system, where it should be chaos.
