Understanding Gravity and Its Mysteries

What is gravity?

We have no idea. Okay, next question.

I don't know.

Nobody in the entire world knows why that falls.

So what is pushing this?

Here.

Why does that fall?

Newton didn't know.

We can describe it pretty accurately, but no one knows why.

We can describe gravity. We can say what it does to other things.

We can,

we can

measure it, predict with it.

I don't need a computer to get a kid interested in that, to spend a week

playing with gravity and trying to understand it

and come up with reasons why.

Well, so what is pushing this?

I, I, I don't know.

Nobody knows why.

So Newton simply

threw his hands up and said, "I don't know, so I'm gonna

invent something called gravitational pull."
