How do I create a time machine?

You'll need two controlled singularities. Then you need to configure the geometry of time/space around them and then you pass matter in between.

How do you know it will work?

I'm a space alien.

An effectively infinite and ultra-dense rotating cylinder ought to do it.

If length that is effectively infinite is a budget issue for you maybe flare the ends a bit to compensate for edge effects, but that last is not guaranteed to work.

Ever since I was a little kid I always hoped I'd get abducted by aliens

We don't abduct, we just merge into your society and study you.

the universe is just a set of fundamental particles and nothing more. it's also finite. so all you gotta do is log all of the fundamental particles as information and then use said information to reconstruct a new replica 1:1 universe

Reductionism is outdated. Learn2metaphysics

Just fly into a special kind of black hole and exit at the correct time

You don't. You send yourself an already made time machine from the future.

Duh.
