http://www.ted.com n clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein’s notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory may soon be put to the test at the Large Hadron Collider in Geneva.)

in deed, it’s an over simplified explanation and he should have commented on that. The way one should think of curved space-time is that planets don’t move in circles due to gravity, but rather that space is bend into a circle in the vicinity of a star and that planets move in a straight line within that curved space-time.
You should try the …
You should try the “The Fabric of the Cosmos” by Brian Greene, I’m not totally sure whether String Theory is included because I found it a hard read and have taken a break from it but if you want some awesome theories to break your mind before bed it is a good one.
This is a really …
This is a really good video, probably the first version of String Theory I’ve not drifted off during. I’m quite skeptical about some of the modern theories, but string theory has a strange charm about it that feels right like it is abstract but you can’t help but love it. The other bug bear I have is dark matter, I mean ok if it exists great but don’t go making theories using dark matter until we have actually detected some of it, until that point comes I’m not a believer.

Don’t be such a fool – Isaac Newton knew what gravity was; he just didn’t understand why the phenomenon occurred – enter Einstein.

the analogy at 3:15 is stupid because it uses gravity to explain gravity.

So what ARE the other 7 dimensions that make up space?
How about “dark …
How about “dark matter” and how it might manifest gravity waves and other torsion waves ?. The universe is 70% dark matter, so it should be the place for us to look. SUperStrings are interesting concept but if they can factor in dark matter explanations in those 10-dimensions, they might just have it.
correct me if my …
correct me if my logic is too childish ..Even though it is not mentioned in this video..the concept of dark energy can be deduced from the presentation of the effect of gravity resulting through the curvature of space time ..eye openar..
centre of milky way has not that much mass to make solar system rotate around it ..Hence the concept dark enery ..or the motion of stars in the outer disk is not in speed as mentioned by Newton.

those 19 minutes flew by just like that! …by the way money is the ”holy grail” you are made to believe!

so what will we be able to do with the knowledge that there is an other dimension?
i think just to know there is one is a pretty expensive waste of money
look i also agree …
look i also agree with you in some ways where i dont think that science and religion are so seperate in a sense… they may seem like 2 different faces of medalion but they both come from the same mammal characteristic ‘curiosity’… and we do have a lot of examples people searching for truth in the name of god. So faith both can be barricade and inspiration

I know it is coming …
I know it is coming from somewhere. I still have a few theories I just have to continue to test them. Eventually I find it was a leak…in the roof allowing water to run down the inside of the wall, then across a joist in the ceiling and drop onto the wallboard. Now how did that hole get in the roof…well, I have a theory.
my theory of a leak …
my theory of a leak in a pipe. I start to investigate the exposed pipes under the counter etc but see no evidence of a leak. I theorize that a pipe that runs closest to the spot must be at fault. I cut a hole in the ceiling, sure enough there is water but the pipe closest to the leak is not the problem. I theorize it could be a drain pipe leak maybe around the toilet, perhaps the wax ring. I change that but the leak cont. I know there is a leak…I can see that
Science is not a ” …
Science is not a “religion” in the way Christianity is. Science always trys to move forward, to prove a theory, or disprove it and reform the theory. Lets put it in simple terms. I have a dark spot on my ceiling. I theorize it is cause by water. I get a chair and have a good look and it is in fact water. I then ask, how did it get there? I again theorize that a leak from some pipe has cause it. I go upstairs a relize my bathroom is right above the spot of the ceiling. This strengthens …
Educated theories …
Educated theories are better than blind faith in an old book. No Christian tries to prove / research God, because if they did than they don’t have faith and if they don’t have faith then they don’t go to heaven according to the bible. Science conducts research to try to prove theories, nothing is set in stone unless it has 100% proven, so don’t even try to compare Science with Religion. Religion = Ignorance whereas Science = Understanding & Reason
This is just naive …
This is just naive approach, to put it politely…
If you take science …
If you take science to a high enough level, it ultimately becomes religion. For the last 10 years or so to say the least, advanced physics has been nothing but theory. Theory requires belief. I think this statement proves my point.
