Do not simply regurgitate watered down layman's "String Theory" (ie, Elegant Universe)

My left-handed son claims that any baseball thrown by a left-handed pitcher automatically curves because of the earth's gravitational pull. He says it's not possible for a left-hander to throw a straight pitch. I've seen him pitch and I totally disagree with his theory. He has not been able to find any written proof that his theory is true. I say that right or left-handed, the pitcher has an equal chance to make a pitch curve because the ball will automatically have some rotation to it no matter which hand it comes out of.

Can anyone provide proof either way to we can put this debate to bed?

Let me rephrase since we are in relation to the center of the galaxy moving upwards of a million miles an hour, does that mean that time moves at a slower rate here than it does at the center of the galaxy.

We all know that time slows down when an object travels to the speed of light. However, what is the speed we are all travelling in at present. If we are not moving, will time move at an infinite speed?

Apart from the size and structure of a heavenly body, could their lack of an atmosphere somehow contribute to its low gravitational force?

I know that plasma is an atom stripped of it's electrons with the nucleaus tightly packed, well since fire isn't solid liquid or a gas could it be plasma?

My understanding is that most satellites are about 100 mile out. How fast would a satellite need to be traveling to be launched those 100 miles from earth? To make it a little easier, lets say the satellite is launched from Denver. Again, no rockets on the satellite, just the velocity needed to overcome the earth’s gravitational pull. Pointing me in the right direction is fine i.e. equations I need, websites, whatever. TIA!

After all why? What was here before there was this universe. I have heard that there was an explosion and since than universe started to expand and it is still expanding! So if the universe wasn't here what would be here.

I know what I am trying to ask is not clear but think about it, you might have the same question.

For example, you get water in a cup, and you place it in your table.
And when the airplane turns to change direction... the liquid doesn't spill! Have you noticed? It moves a little but not as much as the plane's turn... why? Why drinks don't spill on airplanes?

It is not what I have seen but just heard. I don't know if it is true or not. I have heard that a laser beam is strong enough to be used in the dark sky. I am really astonished, When i use a torch, I can feel the final contact point where the beam converges to form a round image. The round image it not formed until the beam strikes some opaque object. Is it same with the laser beam or is it different? Doesn't it need any such thing to indicate the final contact point, where the beam converges? Please tell me what happens when a powerful laser beam is shown up to the dark sky.

A delivery boy needs to know his projectile motion to throw a paper horizontally from a height of 1.40m to a door that is 13.5m away. What must the paper's velocity be for it to reach the door?

I tried using motion equations to solve this problem. I feel as if the problem isn't giving me enough information for it to be solved. Please help me if you can! Thank you!!

I noticed earlier today that water sticks very well to ice, just as well as it sticks to other water.
It made me wonder whether it's called cohesion or adhesion when water molecules "stick" to ice molecules.
My guess would be that it's still called cohesion, but I'm not entirely sure.

We installed a fan in the living room, and for some reason the house feels cooler in every room. We even upped the temperature in the thermostat by 3 degrees. I though a fan didn't really cool air, but simply blows air on your skin making it seem colder. Does anybody know?
