Originally posted by cviper 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 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?

If you think physics is trippy, try reading Plato or Aristotle on the theory of forms.

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 shit like Whitney inventing the cotton gin, or maybe even the Civil War.

Originally posted by BeatFreak 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.

Originally posted by Exodus17 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 [/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.

False, the closest star(alpha centauri or "the dog star") is 2.4 light years away, look it up.

i have gas

that was caused by physics

One more thing...Why does everyone have to associate someone who provokes a perplexing thought and actually uses their head for once as someone who potentially uses drugs?? It seriously is starting to drive me berzerk.

You mean, into a drug-filled rage?

PIcking up on your first theory.....

It would be impossible to see into the past, unless you could travel faster than the speed of light, which is, of course impossible, as this is 'natures speed limit'.

Sorry to spoil the moment, but was an interesting read and I had to think about it a couple of times.

uhm....some of the stars we see in the nightsky are long exploded. We already see into the past...

and scientists have already broken the speed of light multiple times...

heh, so yea maybe some is alittle far fetched and physically impossible.... its more of a "what if" concept

that ones pretty cool

If tomorrow is coming, then where did yesterday go?

when our ears hear a sound they are actually detecting changes in air pressure.

no air in space. no sound.

mind you, it depends what you define as "is"

there really was no yesterday. its only in our minds that yesterday exists. we have made up this concept of time for our practical use in our daily lives. u sleep at night, u are awake during the day. u hunt in the day, u return to camp at night. u have a meeting at noon, you go home at 5 o'clock.

nature does not have time. humans do. we are able to measure our idea on time by the rotation of earth. if everything in the universe were stationary. there would be no time. time is nothing more than a measurement of movement.

Originally posted by Nou According to string theory, there are 10 dimensions. http://www.superstringtheory.com/

i know a lot about that theory. very interesting. the idea that all matter in the universe is made up of strings of energy that have no mass, "Anti-Matter".

but really, when i was talking about dimensions, is there really a 4th dimension? i really meant, does time really exist? which time is 4th dimension, which is why my question of time went right after that statement. as of yet, string theory is far far from being proven. so, im trying to stay in the rhelm of what we know now, and not of what we will know in the future.

www.mkaku.org This guy is the co-founder of string theory and to me the most brilliant physicist of today.

Originally posted by Nou Or im talking out of my ass...

Yes.

But that doesn't mean everyone else isn't either.

As ::TranceVanDyk:: said, there is no time, there is only movement. We gauge things that we observe moving - we (somewhat arbitrarily) place a standardized scale on this movement we observe in accordance to the periodic vibration of a Cesium atom. That's it.

As such, don't deify time, because it is a construct of man. It's awfully bold to say something just doesn't exist, completely disregarding the credence that thought gives it (see Plato on this one), but just realize that time was not here before man was, and it will not exist afterwards.

Maybe.

Time is not the fourth dimention. Time is an aspect of the third dimention, or more accuratly put it is a reference-based point of view from within the third dimension.

The existence of time makes it much easier to quantify the movements from our point of view (in the third dimension). It's existence is defined by the speed of light, and doesn't exist when the speed of light is breeched.

Regarding the first thought posted in this thread (the one about looking at stars in the sky is like looking backwards in time), I actually thought of it quite a few times. I never took it quite as deep, but then again I wasn't stoned out of my tree either. I told it to my sister once, and she almost smacked me.

That's awesome, maybe I should get me some shrooms.
