"Wait, are you asking me out?"
Yes, this was another quote from The Big Bang Theory. One of the best.
Although I won't get into just how the heck you get dating out of that remark, because it's more neuro-science related.
Anyways, I thought I'd comment on what I learned while reading "The Day Without a Yesterday" and tell you that I brought "A History of Zero" back to the library today for obvious reasons.
Anyway, in "The Day Without a Yesterday", it talks about how LeMaitre should have gotten more credit for some things that Einstein took most of the credit for. This was because, back when Einstein was around, there began the fight between quantum mechanics and Einstein's relativity. Quantum mechanics, at first, could not agree with Einstein's Relativity, until a Russian mathematician (I forget his name) mathematically figured out how they would go together. Then, Einstein found Special Relativity, a term he coined for the Russian mathematician's formula. So pretty much they worked together for a while on it.
Anyways, when they still didn't agree before the Russian mathematician stepped in, there were a number of debates of Einstein's relativity versus the newly-founded Quantum Theory. Einstein was troubled because it turned out his relativity wasn't so great after all. He was bummed, and he was trying to distract himself by being more outgoing with his friends, but the trouble of his relativity (only General at this point) removed all possibilities of truth without expanding it and changing it somehow. The Russian mathematician pointed out that in his General relativity formula, he needed the upside-down triangle-looking symbol (ummm I have no idea what it's called... That's delta, I think?) which made space-time curve matter, and matter curve space-time, but working with quantum theory just a little bit more.
Then came along Einstein's find of special relativity, which clashed once again with quantum theory just a bit longer.
The reason why I like this book is because it not just shows the achievements of Einstein, but it shows who helped him and who should get credit for what things, too. Einstein didn't do all the work, you know.
Also, more about "The Elegant Universe" by Brian Greene, I find it astounding how similar string theory and my theory are. Except for the garbage can theorem (I still can't type that with a straight face), the fact that I'm saying space-time can rip is intriguingly similar to that of string theory.
I'm curious as to how string theorists say that space-time can also repair itself, so hopefully I'll get to that part soon.
As for "A Brief History of Time", I stopped because I wanted a more one-focus book right now, not a general one (which is weird because usually I prefer those)... I guess it's because I know most of the stuff in that book so I need something more focused on stuff I don't know instead.
Ah well, I am definitely keeping up more with this.
P.S. After a long period of time, I'm planning on putting all the posts into a book-form, so stay tuned!

The Juiciest Part of "A Brief History of Time" So Far...
So, tonight, I wasn't going to post, because my throat is killing me, as well as my stomach... But besides feeling like crap, I did happen to read more of "A Brief History of Time", and it was amazing!
I'm at the part where Hawking begins to talk about Einstein and the French guy (Can't remember his name) making the Theory of Relativity, and I was just getting into the part that most applies here, about the Theory of Special Relativity, which is the formula I had used originally to show why I thought I could pull through with "This does not mean you can't go faster than the speed of light, this means it is inconceivable to us because we are moving into the future, but when you go faster than the speed of light, time flips over relative to you, and you begin going BACK in time!"
Now, I didn't really get to explain the whole theory, so I'll say some more about the diagrammed aspect of it. Yes, I have a diagram, but unfortunately I couldn't find the energy to draw up a good one for the website...
It consists of an hourglass-shaped drawing with a little square near the top left corner of the page, and an arrow showing the square (representing matter) spiraling into the black hole, going straight through an Einstein-Rosen bridge (wormhole) and spiraling out of a white hole near the bottom. On the side there are two markings, positive infinity (the black hole) and negative infinity (the white hole) representing the direction of time away from zero, where you'd be meeting the speed of light, as if represented by a number-line of some sort.
Now, my next goal is to come up with some sort of equation to represent time according to when it flips over, and such. I was thinking of playing with the d=rt formula, kind of, only mixed with E=MC^2, and possibly even more mixed with the Special Relativity formula (which is a bit confusing when put into typing), and making it something of my own.
The Garbage Can Theorem (haha) keeps coming to my mind, and I'm thinking of what Stephen Hawking said too, about how the Creator of our universe (if there was really one Creator, who knows?) didn't have time: That time is only a dimension of our universe, but that maybe time has always happened with the Creator, too, we just don't know. He said that the common sense-way of thinking about time not being connected to space somehow may have to be altered (I mean, it was in 1990 but still), this may solve some of our problems. For instance, time could be a thing of reality outside our universe, too. Or it could only be for this universe, in this dimension. I mean, time doesn't really exist for the second dimension, so why should it exist for the fourth, the fifth, the sixth?
It's interesting to think about what the fourth dimension looks like: according to Lisa Randall, we already know. You see, to the second dimension, you can see one side of something 3 dimensional at a time. So to us, we can see a three dimensional figure that's one side of a four-dimensional object at a time.
Let's look at the hypercube. It consists of two large cubes connected by six smaller cubes making a ring around the middle of the two. If this were to pass into our plane, we'd see one cube appear, and that one disappear, then another cube, then that one would disappear, and so on...
So you see, it's very hard to visualize (I mean, obviously it'd be pretty weird if some random cubes appeared in the night sky and disappeared one after the other...)
But it makes sense, if you think about how if you're only looking at one side of cone, and you make cuts through it (like the plane barrier does) then you can only see slices of the cone at a time. It's sort of like that. You can only see one part a time, because of the way the planes of the dimensions work, slicing the objects so you can only see one part at a time.
Anyways, for tonight, I'm done.. I was going to talk more but I still feel like crap. It was great posting though!
Also, thanks for the follow, nick!
