Your value judgement on mental longevity is rather subjective. :) And it's nice to see you Kortaggio. I have much to discuss with you!

I think what he's suggesting is that the amount of empty space far exceeds the amount of occupied space in the Universe. Certainly, there's trillions and trillions of stars in our galaxy alone, but the amount of empty space between those stars, and between our galaxy and others, is exponentially...

Okay, this all makes sense now. I've looked over friedmann's equations and it's simpler to understand now. One last question, since we're on the topic, given that the Universe expands as the metric predicts it, why is dark energy attributed to the expansion of the universe? Or is Dark Energy...

Ah, certainly then, I agree with you. I suppose I'm just not too fond of acknowledging the trifling nuances! :P In all seriousness though, isn't it fair to suggest that in two Universes which appear to mirror the fundamental cosmological tenets of one another, that the probability of...

Questions like this are rarely very formal in nature, and are mostly just speculation based on absolutes - it's brain food! I doubt the OP was looking for a scientific explanation, insofar as it can be given. Baseless speculation tends to only be interesting if we ignore the idiosyncrasies which...

Or, and I suppose this might answer my previous question, by space expanding, does it mean everything, all matter is also "expanding"? We simply can't notice it due to frames of reference and the fact that all space expands at the same rate?

Okay, so according to the metric, there is some factor (which I'm assuming is unknown?) innate to time that causes the "expansion". I'm still struggling to understand why this phenomenon exists only for space itself, and not things which are a part of spacetime. I'm assuming this is a conceptual...

Most people, Physicists or otherwise, understand that the Universe is expanding. But I'm somewhat perplexed as to how. To "expand", by classical physics, means for an object to extend it's reach in one or all of the 3 dimensions of space, i.e. getting wider, taller, longer, etc. Therefore, space...

Your question would be based on an assumption of a multiverse - and should a multiverse exist, there is no reason to believe it would be finite. In which case, the probability would either be a binary composite approaching 0 or approaching 1. As the above poster pointed out, based on our current...

I've been reading up on Gamma-Ray bursts, and one thing which has struck me is that, when described through light curves, no burst appears to be the same. Given the phenomenon seem to be based on standard principles, that doesn't make sense to me - behavior cannot be random. Is there any way to...

Good choice. Ultimately, your education is what you make of it. Think of the 5 most influential Physicists that come to your head. I'm sure you know a good amount of their contributions, and perhaps even specifics such as papers and theories they have proposed. Now think for a moment: out of...

In addition to iratern's query, which major are you in?

Interesting, so we're in a similar boat. Perhaps you'll be hearing from me the next few months to see how things are going and offer some insight into my predicament! Indeed I am, at Innis... just down the road from you. :)

I'll be at the St. George college. I'm majoring in Engineering Science, however I may end up switching into Physics/Physics + Math depending on my tolerance level for engineering. And you?

U of T is, by far, one of the best research schools in North America. This isn't to take away from the other schools, but if its research you want then UT is the place to go. Good luck! Maybe ill be seeing you next September.
