Apr 23, 2007 - Great lecture, helped my understanding a lot. One thing that I'm still a bit hazy on though: how does time relate to Einstein's General Theory of Relativity? Where does time come in? My understanding is that gravity is the curvature in space created by supermassive objects. The force of gravity can pull anything towards it if it passes by close enough, and that includes light. So what does any of that have to do with time?

Jan 1, 2008 - many thanks for the postings.its a shame that you cant filter out the hiss and fuzz with a simple audio editing program first like audacity, or use a paramic band eq.

Jan 4, 2008 - hahaha man im in grade 10 and have been reading this stuff since grade 8 and it all makes sense .

ossito Says:

Jan 7, 2008 - that is good to hear, keep it up, as a graduate in physics and math, we need more people in the college programs

Jan 7, 2008 - a graduate in physics and math! awesome possum ! ! ! i find math difficult though, shcrodingers time-independent differental wave equation is frying my brain, so hard to wrap my brain around, really advanced mathematics though, but its a funn challlange.

Jan 14, 2008 - our age jst depends on the speed of time passage, if u will traqvel fast lets say to near bout half of the speed pf light thn in the time period of certain years ur age would increase only by a few days or weeks. so as fast u will travel, time will become slower for u and u will get old later;)

Feb 7, 2008 - holy shit...if you can grasp the concept at grade 10 you're a genius.

jesuistahmid Says:

Feb 7, 2008 - but i think in an abstract sense, reading about it all some how makes sense...but really...no one can truly grasp the magnitude of his propositions so easily. (that's what u learn in grade 12 LOL)

Hippyy123 Says:

Feb 8, 2008 - thats what i love about it all! it makes sense ,but yet it will never really make sense , like just everything it twists your maind and really makes you think. i love the challange of trying to make sense of it all, when i know that theres still ALOT of it i don't know and that doesnt make sense. its just a funn challange

Feb 20, 2008 - wat do you think of this: do i have to be a genius in college to consider majoring in physics or extra determined. help me out.

Oct 25, 2008 - Very good.

MrZenic Says:

Nov 2, 2008 - all i know tht the curvature is made on the fabric of time and space. 2ndly, i know tht the nearer u are to the core of the supermassive object, the faster time is.correct me if im wrong.
