Example - A road during rains.

Changing as few as possible of the laws of physics, what would be the effect on life on earth - particularly human life - if there was no such thing as snow?

Imagine it is possible for a human to dig vertically down from the surface of the earth? Straight down for the core, ignoring the heat and larva etc. What would happen as the digger neared the core and how would they transition from go down to suddenly going up as they headed for Australia? WHat would happen to the dirt? Would they be standing over a huge hole as they headed past the core?

There are many predictions made by scientists about the fate of the universe. One of them is the "Big Rip". So the question is, what will happen after the "Big Rip"?

So here's what I think will happen, feel free to correct me if I'm wrong.

1. The universe is expanding and it has been known and proven. If it continues at this rate, every matter inside the universe will be ripped apart.

2. But when the universe reaches it's "elastic limit" and can go no further, it will collapse with great force back into the centre of the universe.

3. When this happens, everything in the universe will shrink back into the size of an electron(or maybe even smaller) with an "infinite" amount of density. This can soon turn into another "Big Bang".

4. And therefore the steps repeat itself when there is another Big Bang.

Example: Imagine a coil of spring. If you compress it very tightly, it will repel back at you with great force. If it is pulled very strongly, it will pull itself back to it's normal shape with great force.

I believe that the universe is like a spring, but the only thing is that it doesn't have any definite shape.

Most people know about 3Ds. And some people have theories on 4Ds. So my question is, how many theories on new dimensions(if there is any) have been created? What are these new dimensions called? And have these theories ever been acknowledged by other people?

Consider a tiny cell. And in this cell there are millions of atoms(or more). Now consider a galaxy where it too, includes millions of solar systems(which looks like atoms).

So the question is, does anybody else think that our solar system is nothing more than a tiny atom inside a cell(known as the Milky Way) of something very, very huge?

Please explain in laymans term waht this is and how it works.

Ok so, I have a foam ball that i squeeze and then release;

Chemical energy from my muscles is converted into kinetic energy that moves my hand, that kinetic energy is converted into strain potential energy when the ball is deformed which when i release is converted back into kinetic energy as the ball re forms, conservation of energy means this kinetic energy much be converted or conserved in some way. Is it just converted into kinetic energy possessed by surrounding air molecules as it pushes them out of the way?....Is there something i am missing?

One extra question; Can the commonly used term 'sound energy' be accurately described mealy as kinetic energy of the molecules that make up the medium within which the sound is traveling? i.e. the kinetic energy of molecules within the air.
