Physics is kinda cool - mind trip/stoner thought

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

Heres another from my GF....

When you hold your hand close to a candle you feel the heat emitted, as you move farther away the heat becomes less intense, the bigger the flame, the farther away the heat will reach... now think of the sun and the heat it emitts, our planet is just the right distance from the sun that its not too hot or too cold to sustain life... they recently discovered evidence of life on mars, those little single celled microscopic thingymabobs... what if that ring of heat from the sun is expanding through space, impossibly slowly mind you, but so much that the conditions needed for things to live are slowly becoming more apparent on mars... "it'd prove the theory of evolution" - my gf

another more simple thought by me - if you ever lay down and stare at the stars( and youve either chiefed it up or are in the process of chiefing it up ) look at the stars and you kindof realise that there really is no solid barrier between you and each of the thousands of little dots you're looking at... and if you had a long enough object you could reeeeeeach out and touch one and if you're on a high enough elevation, you can see the world around you... and how strange everything is and how it all came to be....and...

[/stoner thoughts]

you should read: Schroeder's cat - very interesting and loads of stuff to make your mind wonder....

all 3 were pretty damn cool, but that first one blew my mind!!!!!

i wonder

u got me thinkin

very cool man

give this man a gold star. if i was fucked up they would of given me SOOO MUCH to think about. but sober. its kindda cool! A+

stop SMOKING! :P just kidding pretty interesting thoughts. if you take ur gf's idea that the light is the hottest at its central source imagine how hot it must be in the middle of the sun :P and what is so powerful to emit such heat/power/light

hehe yea the first one is from a guy who was shrooming and laying down on the grass out in our friends backyard and said - "whoa! im like laying on a huge chunk of matter floating through space"...and how do i know that when i look up im actually looking up?... for all i know i could actually be looking out and to the side, which way really IS up anyways?



heya pink did you pick the little PR flag from the site or did you add that on your own... i need one send me a PM boricua!

number 1 could never happen because we could never get to another planet or whatever fast enough so that the light from WW2 or whatever would reach us. I've never been able to explain this well.

Since we cannot travel faster than light, we ca never be far enough away to see light from the past travel toward us.... is that light came from the same place as us....

answer to the first one is basically yesh - providing you could see the detail.

the one that fux my 'ed up is "where does the universe end" ?

if it does, what's after it? and the toher side in the opposite direction...?

if it doesn't....what shape is it?

ow :\

u nerds are fucking up the stoner thread!

yep what you mean is that, if, right now, within 1 second, we could be 5 light years away, we could see what's going on in the year 2000.

but we can't be 5 light years away in 1 second

That first one is pretty cool.


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.


You also have to think that there is stuff out there and explanations for the universe that are even beyond human intelligence. Humans are only so smart and we may never know what is actually going on.

Hm, first one wouldn't quite work, I don't think. For you to discern any sort of detail, you would have to get close enough to actually SEE what's going on (through the use of this "super telescope"). By the way that light works, the closer you got, the more relative towards the specific inertial reference frame you would come, so if you actually had a vision which was able to see Earth as it is, the light you would be collecting through your eye (that's how you see things, is reflection) would register in that specific point on the time-space continuum. Therefore, you could not see back in time, and look at all the little details of what happened. But it is true that the light you see from stars is millions of years old - but that's only relative to your location on Earth in accordance to the specific inertial reference frame as defined by your exact position along the space-time continuum. If a bigger fish would like to tell me I'm a dumbass, feel free to do so - I'd rather learn more about this more than anything else.

Scientists do believe however, that a distant star in the Milky Way Galaxy went Supernova a few hunderd thousand years ago. So about any time between now and 2100, we could get a VERY bright show in the sky that could last a few weeks. They predict that it will be brighter than the moon at night.

However, this sort of chaotic randomness creates its problems for us. Though we believe that there are not any stars close enough to Earth that are in danger of going Supernova (therefore destroying this planet), there is always the danger of two black holes merging. Because of the nature of these things, and the relatively low budget NASA gets (some people would rather spend money in Iraq ) We can't look at everything we would like to. This arises the possibility of two black holes merging, which, although it creates a wormhole (theoretically), it also emits what is called a Gamma Ray Burst. That would kill every living thing on Earth in under 12 seconds if it hit us at all.

Just goes to show - we're not shit.

It naturally depends on how far the star/planet is. In order to see WWII, the planet would need to be 62 light-years away (is this the proper name?). In order to see the dinassaurs, it would have to be far, far, more than far away.

(You'd need an incredibly precise telescope to see a simple house, for that matter).

i love you.

can i use that in my sig?

Black holes are seriously awesome

thit thread rules
even if its not scientifically correct, that first thought was the coolest thing i've heard in a while

http://www.rednova.com/news/space/1...hing/index.html

First potential solid evidence of String Theory discovered

Yeah quit smokin' for real

stop thinking and start drinking it doesnt matter you wont get there in the end :P

haha, i didn't really think I knew too much about physics and stuff, but from reading these replies, I think I do. of course if you were hypothetically on a place that is light years away and you had a hypothetical devise to view the earth, you would see the past. that is only because we define time through relative experiences.


if you wanna know another 'mind blower' (this one shut a stoner up one night so I could sleep, he kept trying to talk..judas)....when you look at stars, that is not really where they are. As the light from each star travels through space it is pulled and pushed by the gravity of stars it is passing by. so it refracts the light making it appear in a different location.




and ther is no sound in teh space...z0mgz0rz

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.

drugs are cool, they make you hungry and like music

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
