I’m told that they are highly reflective and they are some of the most perfect spheres in the universe. Are they like giant mirrors?
What is stopping us from making a telescope powerful enough to aim at a cold neutron star, say, 20,000 light years away and being able to see Earth as it was then? Even making a telescope powerful enough to be able to see humans walking around on earth as they did back then? I want to see what Neanderthals looked like and also see if the ancient Egyptians were actually black people or aliens.

You are free to do that if you like. You see any telescope cops around?

Planck is stopping us.

First of all, the light has to get to this mirror surface from earth to produce a reflection. If we looked at a mirror from 20,000 light years away, we would be seeing 40,000 years into the past. Not to mention, we have to acount for the earth's position change, which with the spherical shape of the mirror would result in it being off-centered and therefore skewed. Is this even worth it?

Maybe..

I don’t know who that is.

Neutron stars can rotate extremely quickly. Could there be a neutron star that rotates so quickly, that the surface gravity at the equator could be equal to 1G? And if this neutron star had cooled down to Earth temperatures, could you conceivably stand on the surface at the right spot?

planck is a little goblin who lives inside subatomic particles and holds them together, but his arms can't get any shorter so we call that length a planck length

A neutron star would have at least around 1 solar mass. So no.. you would get crushed by the gravity. 1 teaspoon of a neutron star’s material would weigh several tons on earth.

>>16920967
I thought a teaspoon of neutrons masses as much as a mountain

I dont think so, the surface of a regular neutron star allready reaches relativistic speeds

But still interessting to think about how it would feel to stand on an object rotating that fast

>>16920967
Nigga, I said you stand at the spot where rotation cancels out surface gravity enough to where you would only experience 1 g of downard pull.

You become spagetti too. At that speed the g force between your head and your foot are very differerent.

Also coriolis force would be insame
