I understand quite a lot now thanks. But i still don't get where did the dark matter come from that's expanding the universe even more and accelerates it🤔

But matter can't be created nor destroyed right? How did small atoms expand themselves to become size of galaxies. I thought big bang was like a supernova where a massive amount of matter exploded. But if universe really starched itself like rubber then how does dark matter exist in between galaxies and which external force was applied on universe to stretch it?

No, let's take inflating a balloon for an example.you blow air to it and it expands (take that as big bang) now that it expanded it's hollow inside(there's only air in it) now mark 2 points on opposite sides of the balloon. Imagine that our Galaxy is at one point and at the point onopposite side is another Galaxy. We might be looking at that galaxy and then observe that there's lot of empty space in the middle( middle of balloon filled with air). But we don't see anything like that so big bang is fake?

Shit, i once tried a Lenovo laptop which was playing 8k video on a 1080p display 💀

Can i play 8k videos on mac safari? I couldn't find a setting to go above 4k
