Gravity doesn't exist.

A Scientist Takes On Gravity

A long but very worthy read. Please don't comment unless you actually read it, the title sounds ridiculous but its a very interesting read.

Quote:
“Gravity,” he said recently in a talk at the Perimeter Institute, “is the thermodynamic limit of the statistical mechanics of “atoms of space-time.”
I only have a vague understanding of what they are saying in this article, I had to read more elsewhere to get a better grasp on it but its still just beyond me. Hell, even some of the worlds top physicists don't understand it.

My issue with the theory as I understand it, is that gravity is so predictable and 100% calculable. The attraction between objects of any given mass can always be mathematically proven, same with its predicted inertia and escape velocity.

Quote:
Think of the universe as a box of scrabble letters. There is only one way to have the letters arranged to spell out the Gettysburg Address, but an astronomical number of ways to have them spell nonsense. Shake the box and it will tend toward nonsense, disorder will increase and information will be lost as the letters shuffle toward their most probable configurations. Could this be gravity?
This makes good sense, but when applied to gravity it seems to be almost the opposite of how we understand it. But then again so does quantum mechanics but it keeps getting proven over and over again.

Maybe some of you smarter than me can put these things in laymens terms for us simple folk.

I'm going to read over it again in more detail but I think this is as "laymens" as it gets for now

I read the article and admit it's over my head.

But....if gravity doesn't exist on Earth, what force does an astronaut escape when he/she enters space? What is the state that astronaut is in in relation to gravity, non-gravity while in space?

If you like this sort of thing, you should read some of James Gleick's books. He does an awesome job of explaining some of this type of thing. His Chaos book is great.

I've glanced at string theories for over twenty years, not that I understand it, but if you just pay attention long enough you'll see that most of the people who propose whatever version they are on don't really understand it. It falls apart because of the needs of small, multi dimensions that really don't fit in like a jigsaw, which is what we want, and it can't be proven.

Hell, Magnetism is a fifth dimension, where does that fit in?

With that said, you can take a look at Gravitons to get an idea of where he's coming from or going to or not going to.....
or read into the new particle accelerator they've got.
It was the one in the movie Angel and Demons.

best thing to do is fire up a and read it several times reeeeeaaaaallllll slow.

Take it with a grain of salt, if you study it long enough, you'll find it changes constantly, and most of the people who play with string theory really don't have a good grasp on "Gods Glue".


I know that damn green pinecone that fell out of the tree and smacked me in the head was real and under the influence by something.....

I'm no expert but maybe because the earth is spinning so fast? It goes ~1,038 MPH at the equator....Thats mind boggling....(to go with the scrable analogy)

I think that if there wasn't gravity, we'd be thrown off the planet due to centripetal force (not centrifugal force).

You guys are missing the point. They are saying its not gravity that is keeping us down. They have another explaination.

I was just explaining to Pakman that it's not the Earth spinning that keeps us grounded.

Think of the universe as a box of scrabble letters. There is only one way to have the letters arranged to spell out the Gettysburg Address, but an astronomical number of ways to have them spell nonsense. Shake the box and it will tend toward nonsense, disorder will increase and information will be lost as the letters shuffle toward their most probable configurations. Could this be gravity?

I'm fixing to read the article, but on the surface I have a slight problem with the statement about the Gettysburg Address. It seems to imply that chaos and disorder is the natural state of the universe. We know from the predictability of elements and their make up (as seen on the periodic table), from the patterns and figures formed by galaxies, and even from the nature of a circle and its relationship with Pi that through all of the chaos in the universe it actualy attempt to create order, rather than drift away from it.
Anyway, that's just my off the cuff reaction to that bit. After I think about it for a couple hours I'll probably poke a couple hundred holes in my own theory, but until then, I'm going to read the article now.
