It used to be, a thousand years ago, that if you wanted to explain why the moon moved through the sky, you needed to invoke God."
- linga99, on 07/04/2008, -13/+47Deep...
- DirtPile, on 07/06/2008, -2/+31So does this mean it actually *is* possible to make the Kessel run in less than twelve parsecs?
- ColinCampbell, on 07/06/2008, -1/+29But the fact that these constructs exist mathematically do not make them real in a physical sense, just possible.
- inactive, on 07/06/2008, -33/+5842.
- hugoguzman, on 07/06/2008, -3/+24"But it simply has to stop somewhere"...says who?
- uptwolait, on 07/06/2008, -1/+18Yeah, but what's the turtle standing on then?
- humanerror, on 07/06/2008, -0/+16Light leaves the sun and 8 minutes later it arrives at the Earth. The name 'minutes' and the number 8 are arbitrary, man-made conventions, but the actual interval between light leaving and light arriving is not. The interval is an aspect of spacetime that we 3-dimensional creatures call 'time' for convenience.
- oilcan, on 07/06/2008, -0/+16mathematically speaking, it is definitely a 4th dimension. A cross section of a single dimension is a zero dimension singularity, or a point. A cross section of a 2-dimensional plane is a line or a single dimension. A cross section of a 3 dimensional space is a plane or a 2 dimensional plane. A cross section of a 4 dimensional space is a 3 dimensional space. And note that nothing ever changes in these examples. I'm not saying, hey, look, the dot on the line is travelling from here to there. because this indicates change or progression of events within a system. now, if you take any single particular moment in our 'time' you could describe it as a 3 dimensional space. but being a cross section of a progression of events, it is as it is, nothing in it changes. An effective cross-section of 4 dimensional space is nothing but, well, space. so, given that time is thought of in this way, it makes absolute sense to consider it a fourth dimension. length, length and width, length and width and depth, then length width depth and duration. hope this makes sense.
- Pylons, on 07/06/2008, -3/+19"Time is an illusion, lunchtime doubly so." Douglass Adams ftw
- humanerror, on 07/06/2008, -0/+15another turtle
- Kyrgizion, on 07/06/2008, -9/+24Our universe is observably 3-dimensional, 4-dimensional if you count time.
Mathematically it is possible to prove the existence of higher dimensions. So it seems logical that our "all" is, in fact, merely a part of a bigger whole indeed... - wolferz, on 07/06/2008, -0/+13Given an infinite universe there are infinite possibilities. Given infinite possibilities in an infinite universe with infinite time, all possibilities will come to pass.
- dullnation, on 07/06/2008, -1/+13I always wondered about that concept. Does that mean that every peice of fiction ever written could have actually taken place in another universe?
- humanerror, on 07/06/2008, -0/+12no I'm pretty sure it's another turtle
- aphexcoil, on 07/06/2008, -4/+16You guys may want to read up not only on multiverses, but multiple worlds theory, too:
http://en.wikipedia.org/wiki/Many-worlds_interpret ...
(Previous courses in quantum mechanics will be helpful, but not required) - inactive, on 07/06/2008, -2/+13Actually, science didn't say that, religion did. And it was more than just a "few hundred years ago". Science ended up proving those ideas wrong, and it's why the earth is no longer thought to be flat, nor the sun thought to orbit earth.
- DukeMojo, on 07/06/2008, -1/+12Revolting? Impossible? What? How?
- MattNF, on 07/06/2008, -3/+14Oh man, it's like you're TRYING to get dugg down.
- Amadeus2490, on 07/06/2008, -6/+16Sean Carrolls' penis is showing.
- 5730, on 07/06/2008, -4/+14"In his studies of entropy and the irreversibility of time, Caltech physicist Sean Carroll is exploring the idea that our universe is part of a larger structure"
In other news: USA exploring the idea that its part of a larger planet.
OH digg me down please! - orenshk, on 07/06/2008, -6/+15woosh
- inactive, on 07/06/2008, -1/+10I think you misunderstood his point. The reality is that there is ZERO amount (not a shred) of certifiable proof that any kind of spiritual presence exists on this planet, or in the universe. Why should he even stop to consider that because people (who are, for lack of a better word, ignorant) are too afraid to admit their own mortality that they cling to a false sense of security within spirituality - would have any kind of presence in something such as science? All main-stream religions have gone out of their way to try and debunk, hide, and blind the populace from scientific discoveries because the truth of science out-weighed the "belief" of faith. In other words - god has no place in science, and nobody as intelligent as this man should stop to consider another alternative that's never been proven (and can't, and never will be).
- vinceislegend, on 07/06/2008, -4/+13Titties.
- nikehat, on 07/06/2008, -0/+8You wouldn't even if you had.
- DukeMojo, on 07/06/2008, -4/+12Not theoretically...
Food for thought: If there's something, then there was probably always something; because something cannot come from nothing.
0=/=1 - dizzy113, on 07/06/2008, -1/+9"Is that seriously the best post you could muster?"
Dude, its 42 c'mon - plnegative1, on 07/06/2008, -0/+8Dude... it's time to take your medicine
- JerzyBricklayr, on 07/06/2008, -0/+7Did anyone else immediately think of the move 'The One' with Jet Lee after reading the title?
- WarpDigger1492, on 07/06/2008, -2/+9Ironically, I just finished the Golden Compass trilogy.
Very deep stuff. - desertDenizen, on 07/06/2008, -0/+7Smart people. If you're not intellectually curious, you wouldn't understand the idea of intellectual curiosity for its own sake. Go watch tv.
- YAOMTC, on 07/06/2008, -0/+7You managed to bash both Bush AND religion on a science submission. Dang, man.
- AreTooDeTo, on 07/06/2008, -3/+10you're saying "it simply has to stop somewhere" believing 100% that what we know about physics is completely correct. the fact of the matter is that we know so little with physics and the universe. or we know everything. what i'm saying is that we do not know how much or how little we know, so it's naive to say that things need a beginning and an end, because that just might not be the case.
just a question to think about, if things need a beginning and an end, where does the universe end, or where is the ending point of everthing? how did time start? will time ever end? they're meant to be a rhetorical questions but you can respond if you have an answer if you want.
and i'm sorry if i came off as hostile, it's just the way i type. i'm just trying to share my point of view on the topic. - Kristijan12, on 07/06/2008, -0/+7That is a cool thought.
Have you also considered that in some other universe you have probably dated "that" girl you just don`t have luck to date here? - CptBuck, on 07/06/2008, -0/+6Thats not ironic at all.
- FirEnRain432, on 07/06/2008, -1/+7I totally agree. time has always baffled me, especially the one time in 1998 when i was on my way to the cinema to see rain man and i got caught in some traffic and a bunch of time went by causing me to miss part of the movie. i was angered so i telephoned my neighbor and told him he oughta learn some respect or the people in michigan might just have some words to say to him. he was obviously confused so i tried to clear it up for him by recommending that he reads saturdays newspaper (the article about the tree people)
- AreTooDeTo, on 07/06/2008, -0/+6well, what if we got the name wrong? that's why they are saying it is possibly a multi-verse
- DukeMojo, on 07/06/2008, -2/+8That....actually makes a lot of sense. I never thought of entropy and time in such a way. Way to think outside the box!
- jebudas, on 07/06/2008, -1/+7The way I always think of it is that you can plot a point on an XYZ axis and that's 3D. Now start plotting points and also moving the axis, that's 4D.
- KaiUno, on 07/06/2008, -1/+7If you're going "oh well" anyway, would it be so hard to just not type it up at all?
- FreeTalkLIve, on 07/06/2008, -7/+12Our universe is a cancer growing on a larger universe.
- gordonj, on 07/07/2008, -0/+5Humans are incredibly bad at naively gauging probabilities of events occurring. If for instance, to use the above example, somebody recovers from a form of cancer that has a 10 percent chance of survival, the probability is of course 0.1, which seems like quite an unlikely event, however if you take into account all of the people who have the cancer, the chances that some of them will survive is very high. For those people who do, it is not a miracle, they are just the lucky ones in the 10% who survive on average. This should be self-evident, but it seems that people are often effected by an ascertainment bias, where they don't take into account the misses as well as the hits. Surely for something to be a miracle it must be impossible to begin with, otherwise it is just chance.
- BelatedHero, on 07/06/2008, -0/+5Entropy, how can I explain it? I'll take it frame by frame it,
to have you all jumping, shouting saying it.
Let's just say that it's a measure of disorder,
in a system that is closed, like with a border.
It's sorta, like a, well a measurement of randomness,
proposed in 1850 by a German, but wait I digress.
"What the ***** is entropy?", I here the people still exclaiming,
it seems I gotta start the explaining.
You ever drop an egg and on the floor you see it break?
You go and get a mop so you can clean up your mistake.
But did you ever stop to ponder why we know it's true,
if you drop a broken egg you will not get an egg that's new.
That's entropy or E-N-T-R-O to the P to the Y,
the reason why the sun will one day all burn out and die.
Order from disorder is a scientific rarity,
allow me to explain it with a little bit more clarity.
Did I say rarity? I meant impossibility,
at least in a closed system there will always be more entropy.
That's entropy and I hope that you're all down with it,
if you are here's your membership. - boombye, on 07/06/2008, -0/+5Not to be confused with Xenu.
- inactive, on 07/06/2008, -0/+5Good series. It deals with the string theory, the basics of it at least and adds fantasy elements.
- juniorb, on 07/06/2008, -2/+7I stopped at OMG.
- NewSc2, on 07/06/2008, -2/+7"Can you give me a simple explanation of entropy?
One way of explaining entropy is to say it's the number of ways you can rearrange the constituents of a system so that you don't notice the change macroscopically.
If you mix milk into a cup of coffee, the more mixing that occurs, the more disordered the milk molecules become and the more entropy builds. If all the milk was somehow separated from the coffee, that would be low entropy."
That's gotta be one of the worst explanations of entropy I've ever heard of. He could have used the perfume in a jar example. And number of ways you can rearrange constituents without changing a system's macroscopic properties? I get it, but, still... - RAGEdemon, on 07/06/2008, -4/+9Wow... I wish Bush could be this articulate.
Hopefully a few centuries down the line, thanks to people like Darwin, Newton, and this guy, people will look back and laugh at how people used to believe in magical beings in the sky... Even the president of the united states who made all his decisions based on such beliefs.
Much like how today we laugh at people who used to burn poor old grannies as so called "witches" in times past.
"Thou shalt not suffer a witch to live".
WTF? Witches exist? Oh the bible says they do? Then it MUST be true! :D - nemojonze, on 07/06/2008, -3/+8our universe is a fart from the ass of the multiverse.
Dugg for the dodge and burn halo around Dr. Carroll's dome. - DuffyDirect, on 07/06/2008, -0/+5he combined pokemon with the jet li movie 'the one'
