| also due to a thing called spacial elasticity the farther away every gets from eachother the faster it travels. In time, no stars will be visible from earth! and before they were so close we couldnt see past the light blur....were in a good time, woot! plus we are in a good spot in out spiral arms so we can see past the arms and are far enough away from center of galaxy to get away from dust and light...so lucky :D |

Sorry for being sceptical to that, but
a) gamma ray bursts are quite common. Although a single burst is extremly powerful we won't notice much due to the distances involved (a huge burst measured on 27. december emited more energy than the sun does in 150'000 years, see here ). And where do those 12 seconds come from :conf:
b) AFAIK it's not quite incommon for black holes to collide (at least if you move towards the center of the galaxy). On the other hand, I'm quite sure that, what people think are stars "colliding" with black holes, have been observed. |
I only know what I've been told. Thanks. ;) |

can anybody tell me where space came from? this vacuum which we occupy. the endless vacuum of space. where did this come from? how was "space" created. and then, how was "matter" created? how was matter with "Mass" created? mind how the universe was created. How in the world was the vacuum of space created? are there really 4 Dimensions? or three? or 5 maybe? does time really exist?
with many of these questions, you enter from known natural laws into the rhelm of quantum science and philosophy. is everything relative, or is there one absolute? |

Great thread, I love talking about this kinda stuff... but I am seriously wasted myself and cant be bothered typing...
But I like that bit about no sound in space, which reminds me of:

| if space expands so quickly, that would mean time expands with it. think, if you were ever able to see the "edge" of the universe, youd be looking into a time before time existed... |

Blackholes only suck in things inside of the event horizon. That is to say, if our sun collapsed into a blackhole right now it would have the same mass as before and its graviational field would still be at same point. If you took a neutron star (our sun, just the size of a good sized city like seattle) and put it in our skies, the entire planet would wrap around it and be compressed to 1/4 inch hehe.
I drop of a neutron star would go straight through the eart about 8000 times before settling in the dead center!
btw terms: white dwarf: compressed to the point where atoms cant get any closer. Novas happen when in a binary pair, they siphon hydrogen off a red dwarf until Hydrogen gets so compressed the entire surface of the star explodes! Its mainly iron at this point. If you look at table of elements a big star collides hydrogen so hard it turns to helium, it collides that so hard it turns to bla bal eventually reaching iron which cant explode or divice any more. Counting back from plutonium which is created and destroyed also middles in iron.
Neutron star: when the mass of the star is 5x or greater than our own. The gravity is so intense it breaks past the electron repulsion and the NEUTRONS are touching!!!
Pulsar: Neutron stars typically spin so fast and produce so much energy that a HUGE beam of gamma radiation is shot out like lasers from the poles. Sometimes we get something that is rotating towards us and we get a blink every 15 seconds or so from the entire planet spinning around and hitting us with that. First thought to be message from aliens!
Black hole;;;;;when even neutrons can not hold up against the pull of gravity OoooOOOOoo |

The closest star to our own is approx. 200 light years away, so if there is intelligent life on a planet orbiting this star (personally, I believe there is much within our milky way) and they were observing earth with powerful telescopes, the light from earth would have taken 200 years to get there, so what they would be watching is like Whitney inventing the cotton gin, or maybe even the Civil War. |

But what about this one? You know how people say they see UFO's and little aliens with big heads and eyes and small bodies?
What if those aren't UFO's but they are actually humans from the way distant future who have evolved into that traveling back in time to see us? Huh? huh? well? That'd be crazy.

ok so i just got out of physics and we're on the chapter for light/soundwaves, heat/temp, and all that fun stuff and this guy i used to smoke with - who has some crazy stoner moments/talk might i add - presents this idea to me
When you look at a distant star or planet, you are looking back in time, according to the whole speed of light theory thing, it takes light a longass time to travel through space even at it's uber speeds... so the light emitted from a lit up star or planet takes forever to reach your eye - my friend then asks: imagine if you were on a faraway planet and you had like super telescopes and you were looking at earth... because of the whole light/time thing you would be looking back into earths past while in reality, here on earth we'd actually be years and years ahead of what you see from the distant planet.... so his question was.... if we were on a distant planet right now, do you think we'd be able to look at earth and see WWII, or maybe even farther back into the days of the Roman Empire, or the Egyptians... or even see the dinosaurs?....
crazy idea i thought id share:crazy:
[/stoner thoughts] |
I was first introduced to this thought in my astronomy class last year, and it still has me thinking about it today. There isnt any known explanation or statement about it anywhere. Astronomers and scientists alike are still dumbfounded by this possibility. |
