Michio and Neil have already independently explained quantum entaglement.

Say you have two gloves of a pair. You place one glove in a box and the other in another box.

Then you separate the boxes using two planes. Once sufficiently far away you open the box and see which glove it is.

Now you know which glove is in the other box, but you can't tell anyone faster than light, so it's not useful.

You could probably find their papers online if you wanted.

False

a string one light year in length would have more atoms on the beach than there are grains of sand in the universe

Conservation of energy states that if you have two Einstein-Rosen Bridge balloons, as you increase the size of one, the other must decrease, therefore by analogy it is impossible to make any object the size of the speed of light.

Is he our generation's Einstein?

So I have a chemical question which j can't actually figure out. How the fuck do you work out the oxidation number of two elements that can exist in multiple oxidation states?

For example, the formula Cr(MnO4)3. How would you go about determinING the oxidation state for Cr and Mn without just intuitively knowing that MnO4 exists with a -1 negative charge?
