I suggest you look up the term "renormalization"...

Much of quantum theory is actually kind of (educated) guess work. Look at the quark for instance, a totally unprovable concept but the predictions work so quarks are assumed to exist.

Quarks have already been proven to exist, so they are not unprovable. Quarks have been already been detected directly via the scattering of charged particles by neutrons in 1968 and they have recently created a phase of matter composed primarily of quarks and gluons, called quark-gloun plasmas, in particle accelerator experiments.

You cannot isolate a single quark to examine, they only exist in multiples. There is plenty of indirect evidence suggesting their existence but no direct evidence. That was what i was pointing out.

how did such a ridiculous OP degenerate into actual meaningful discussion about real science. you should all give yourselves a slap right now!

All theories are educated guesswork. The current Champion is the Standard Model which has predicted to an accuracy of twelve decimal places and has yet to be falsified outright by contrary observations. I have no doubt the Standard Model will stumble on the matter of the Higgs Boson but that has not yet happened. Any theory that predicts so many things so accurately is bound to be partially right.

+1

Your right. Some people do take concepts in quantium theory so literally that they forget its all work in progress lol.

If an infinite universe can be imagined then it exists.

I hear there's a really good restaurant there. It's easy to make a mess of your food, so bring a towel.

That's doesn't disprove a finite universe.

We will never see enough of the universe by telescope (or any other em wave) to determine if it actually has an "edge" or not. This is because of the way it is expanding. Some galaxy's are moving away from each other at faster than light speeds.

Tell that to people who don't believe it's possible.

A quantum telescope can see into infinite distances.

LOL

Some galaxys are moving away from each other at faster than light relative to position but because its the fabric of space/time expanding they arent actually moving.

Bit of a mind bender...
