Posted July 27, 2009 Love that picture. Space is interesting, but I'm more interested what's beyond the universe. It got to end somewhere. Share this post Link to post Share on other sites
Posted July 27, 2009 A bit more space porn, A Supernova Blossoms In A Neighboring Galaxy, And The Shockwave Is Aimed At Earth See the blue halo around this supernova? It's blue-shifted because of the Doppler effect, which means it's heading straight for us. And the supernova E0102, in the Small Magellanic Cloud, is only 190,000 light years away. Brace for impact! This new image of E0102, from the Chandra Observatory, is leading scientists to believe the supernova's "ejecta" is actually cylinder-shaped, with different "cylinders" of energy moving at different speeds — and we're just viewing it end-on. http://chandra.harvard.edu/photo/2009/e0102/ It's very purddy!!

Posted July 28, 2009 This totally reminded of that Hadron Collider that everyone was so worried would create black holes and destroy the world/universe. New wallpaper for me. Share this post Link to post Share on other sites

Posted July 28, 2009 I remember hoping that the universe wasn't destroyed by the Hadron Collider. I was walking back home after dropping my sister off at the bus, and knowing that it as few minutes until it was switched on. Share this post Link to post Share on other sites

I was walking back home after dropping my sister off at the bus, and knowing that it as few minutes until it was switched on. The funny thing about that is that, on that day, they were only sending the beam one way (no colliding), and the chances of them opening a black hole if they were colliding would have been no different than that chance of quantum mechanics resulting in one randomly - essentially nothing.

This. Alot of Quantum Physics boils down essentially to statistics; sure, it's possible that every air molecule in the room could end up in the corners for a minute, resulting in suffocation for every living thing in the area. But it's so improbable as to have never happened, in all the trillions of minutes that have elapsed in the billions of rooms around the world. Share this post Link to post Share on other sites

But wouldn't that go against the laws of thermodynamics, specifically the theory of entropy? Or do those not work on quantum level? Share this post Link to post Share on other sites

You don't need to be part of CERN's research team to know that. It didn't take too much to find out that it would be slowly powered over months and I'm pretty sure Paj isn't an idiot. Anyways, off topic. It was just a throw away remark. : peace: Share this post Link to post Share on other sites
Posted July 28, 2009 In what specific way do you mean it goes against the laws of thermodynamics? Well, I'm not at all trying to "quiz the Giz on phys". But I've learned that entropy is the level of "chaos" in a system, and that the entropy will never decrease, only increase. Like, for instance, if you drop an ice cube into a glass of water, the ice cube will eventually melt and become one with the water, thus making the system more chaotic. It will never re-materialise as an ice cube because that would lower the entropy of the system, which is impossible on this scale. But I've also read that on very large scales and very small scales (galactic and quantum scales, that is), drops in entropy are possible. The Big Bang is an example hereof. My question is, then, would quantum physics allow for all air to suddenly manifest in the corner of a room? Or does that go against the law of thermodynamics, as it would lower the entropy of the combined system of the air and the room? (I'm sorry if this is totally noob talk. I researched it myself on the Internet.) Share this post Link to post Share on other sites

The universe isn't expanding into anything as it's space itself expanding. For it to expand into something would imply space outside of space. So basically beyond this universe is....nothing.

So basically beyond this universe is....nothing. Ah, right. I only had physics at C level, and some of these things I only discussed with my teacher on my own. I would like to have physics at a higher level, just like I would like to have math, drama, music, etc. *sigh* You can't have it all, I guess. Share this post Link to post Share on other sites
Posted July 28, 2009 What is 'nothing' though? Exactly, that's the question. What would "nothing" look like? But then, as humans we can't actually imagine that because for us to imagine what nothing would look like, we're turning it into something more than nothing. My head hurts.
