Congratulations!

Is it feasible to buy or make your own high temperature superconductors? say under $1-2000

What is the theoretical upper limit of surface field strength on a "permanent" magnet?

Its both a function of % of alligned electron spins and electron density.

for reference, rare earth magnets are ~1.4T at their surface

one of these even

not even the fucking hubble telescope can see it, that thing has a resolution of like 300 feet on the moon surface.

>How do we observe an electron without using electromagnetic waves?

Answer that and you win one of these.

The dimensions in a different universe are independent of the dimensions in this universe. So, a million years experienced in this universe has absolutely no meaning in a different universe (how can it, time in this universe has no control over time in another universe). So, make a portal to a different universe, put a supercomputer in there, and connect it to a supercomputer in this universe. If you have an equation that would take 1 billion years to calculate, you would get the answer almost instantly, as long as the particles in the supecomputer in the other universe aren't damaged/decay through the 1 billion years spent calculating.
