Interesting. I'll come back to this one.

i have a question.

Can string theory be considered as an actual scientific theory, or is it more of a hypothesis?

FACT.
String does exist.

I'm gonna need to see some proof of this ridiculous claim.

Search 'that' cupboard draw in your kitchen (the one that contains the whole contents of the universe's pocket of random items and pocket lint)

It does exist! Sadly, my cat immediately started playing with it before I could perform any further studies on it.

If Percy Shaw (Cats eye inventor) had viewed that cat from behind, he would have invented the pencil sharpener instead.

Ever noticed that when your frying pan got really hot and there happened to be water on the pan, it wouldn't instantly evaporate? But rather bead up into tiny droplets?

This is known as the Leidenfrost Effect. It's when a fluid evaporates so quickly on a hot surface, due to the great difference in temperature, that a cushion of vapour is formed between the fluid and hot surface. It reduces the thermal conduction and so the rest of the fluid takes a lot longer to evaporate.

This effect can be applied in other situations, for example your hand would still be okay if you momentarily put it in liquid nitrogen. In comparison to the liquid nitrogen, your hand would be extremely hot. The field of "vapour" initially formed around your hand acts as a barrier and prevents the liquid nitrogen from freezing your hand.

I also hear Mythbusters did the same thing but this time with molten lead.

How is it that two entirely separate forces both obey inverse square laws?

The field goes outwards in a sphere so the concentration of the force particles is inversely proportional to the surface are of the sphere, which is itself proportional to the square of the radius.

Binary (1 = 1, 10 = 2, 11 = 3, 100 = 4, 101 = 5, 110 = 6, 111 = 7, etc) is identical in how it works to decimal except that you move up the digit after 1 instead of after 9. You can even do math this way:

11 * 11 decimal = 121
11 * 11 binary = 121 (but 2 = 10) so 201 so 1001.
11 = 3, 3*3 = 9
1001 = 9
