So what actually is string theory?

[ScientiaMathema]

Strings, closed loops of energy a planck length in diameter, are the fundamental basis of all "fundamental" particles. Each particle corresponds to a different harmonic on the string.

i am SOO high and this is SOO amazing

[sriram777rrc]

Aren't they going to try creating Big bang now in Swiss or France somewhere?? So.. If would happen successfully?? Don't they help us to an extent to solve many mysteries like this??

2:35 "Trillions of years from now, we physicists believe that the universe will end not in fire, but in ice." - reference to "Fire and Ice" by Robert Frost

3:40 "The string theory may be a theory of nothing, rather than a theory of everything. That's the rub." - potentially a reference to Shakespeare's "To be or not to be" soliloquy ("to sleep--perchance to dream: ay, there's the rub")?

These may be a stretch, but, as they come from someone whose field of study isn't literature, I'm impressed.

Michio said "I and my colleagues", not "My colleagues and I". No wonder this theory hasnt been solved.

one thing i love about science is that no matter how great something sounds how close it is to just fitting, it can still be wrong, while carns new discovery hasnt been proven it just shows we dont no anything, personally i think the quest to glory is more rewarding then finally reaching it because really whats the point to live if you dont have goals, once your life work is finished part of your life is over forever as well

@Michel0555 Strings and membranes are close enough real life models of things you can relate to, like the atom's pudding model in the 19th century. A ten dimensional string is something so far fetched that it might look like a Buick, for all intents and purposes. The term string is just to create familiarity through a common notion. And since it is a purely mathematical notion, it becomes increasingly difficult to explain without the help of things we can relate to.

@MidasRivers

Yes I know that whether H2O is water or steam, depends on the temperature, and temperature can be explained as the rate of vibrating. I just don't get what it has to do with strings or membranes.

[MidasRivers]

@ScientiaMathema yea thats a great explanation. Everyone understands that.

[MidasRivers]

@Michel0555 its the idea that everything in the universe vibrates at different levels. Like solid objects to boiling water to steam. The faster particles move in vibration the lighter they are. Its the idea that we vibrate at 3rd density on a solid plan but there could be densities so high above us that the level they vibrate at is unseen.

@DrKillaser the entire universe is being shaped by that horrible abomination of music...the way i understood the string theory...

[ragasaraswati]

@soulreaver214 I believe so. Maybe energy is like lonely tunes, while matter is like beefy chords.
