Thread: The Scale of the Universe

I'm not sure if it's entirely accurate though, from what I've heard there's never been any evidence that quarks even have dimensions (i.e. they are 'point particles').

If only that Planck Length was a bit bigger; things would get pretty interesting.

What do you mean by that?

As I understand it, it is on the level of the Planck Length that particles behave
very odd, can go through matter, fluctuate, etc and if that length theoretically
would be larger, objects of larger size (so we could perceive it) would behave
the same.

Like, you place a glass on a table and it just falls through.
That would make things interesting.

Oh okay. I was confused because really lengths just measure things relative to one another, so if you made the Planck length larger you'd make everything else larger too and the universe would look exactly the same.

Yeah, weird stuff happens on small scales; much larger than the Planck length though, in fact.

Hehe, yes that is of course right. Didn't mean it like that.

I was wondering, if someone would ask me what I meant.
Not surprised that it was you, though
