Are we alone in the universe?

Time travel is not possible in the sense of being able to change history.

 

 

How do you KNOW that for sure ? ... You don't.

another thing i think is funny, is how we assume, that if there is other life out there, that it has developed hundreds if not thousands of years ahead of us. Even if there was other life, they still cant deny physics. they cant go faster then light, they cannot travel through black holes, etc. so there is no way that another alien space ship would have reached earth because they would have to have left thousands+ years ago and travel at the speed of light.

 

im not saying that going FTL or traveling through black holes is impossible, who knows whats possible, but to think that every other alien race out there besides us has figured it out, is a little extreme. most likely, even another advanced civilization is still only as advanced as we are. give or take, and still cant perform feats of science fiction such as what ive mentioned and more.

That's what I tried to explain previously. People's mentality goes as follows : "Theres ten thousand billion planets out there, therefore we are the dumbest least developped species ever [/ragequit]". People assume that if there's another civilisation, it's necessarily older and so ahead of us that they'd completely obliterate us at anything. Sounds like superstition to me. It's just like 2000 years ago when anything people couldn't control (the sea, mountains, wind, etc) was necessarily a God. Today it's the same thing, but with aliens. Oh, the space is so big, there's obviously monstruously powerful beings out there manipulating all of this. They got bases on Earth, a pit stop, a fast food and a theme park in Antarctica but we don't know because they're just so awesome.

 

It took the Earth 4.5 billion years (1/3 of the Universe's current lifespan) to finally get "lucky" enough to come up with a sentient life form, and we've had millions over millions of different species walking around before us with much more physical capacity than ourselves. It's out of pure luck that some random monkeys were forced to evolve into smarter beings. The chances of there being life outside the Earth are ridiculously high, yes. But what tells you that everytime there's life, there will be sentient life as well? What tells you that every other sentient life form out there has more brain capacity than us? That it developped capacities to teleport and launch kamehamehas and other exagerated Chuck Norris joke abilities that we don't have? Have you ever thought, that when we begin space travelling we might come across medieval civilisations, instead of insane War of the Worlds / Men in Black / Star Wars civilisations? The chances are low but we might even come across a civilisation that is equal in terms of technology to ours.

FTL travel might be possible right now. Eisenstein could of been wrong, because a lot of people at LGNS are claiming they made a particle go faster then light.

 

Also even if FTL travel is impossible, warp holes are still technically possible.

 

no. FTL isnt possible RIGHT NOW. sending an atom faster then light is one thing. (im not disagreeing, that if it happened, how revolutionary it might be) but an atom vs a spaceship is quite different. even IF it turns out something can go faster then light, its not like we will be sending things FTL over night. could take tens if not hundreds or more years before we are capeable of sending anything over the size of one particle FTL.

 

and technically is the wrong word. theoretically is more like it. warp holes are theoretically possible....maybe.

exactly. as i said, chances are, any life we find will be protozoic or at best, dinosaur like...think of it this way. the dinosaurs were around for how many millions of years? chances are, if we come across another life bearing planet with multicellular life, even if it was one day going to sustain human-like life, we would prolly catch the planet in its "dinosaur" stage anyways. its not like life just evolves into humans. there were many stages of life before ours. would there be as many stages every time? who knows. there is no way to tell, but im guessing that there would be just as many steps from single celled organism to human, no matter the planet.

 

if another alien race has mastered space travel and came to visit our planet, assuming it was still bound by the laws of physics as we knew them, meaning the fastest it could go was ~6 trillion miles per year (rounded up), then they most likely came and found our planet when it had dinosaurs, since the window of time that they lived was sooo much greater then the window of time (civilized) humans have been on earth, and then left because there was nothing worth while here (meaning another advanced civilization).

It is theoretically possible to travel forwards in time by going at light-speed due to time dilation, what is thought to be impossible right now is backwards time travel.

And yes, travelling faster than light may be possible due to the information from CERN.

again. something GOING faster then light MAY be possible. us TRAVELING faster then light is another story.

 

hell we cant even travel faster then like Mach 5. we cant even go anywhere near the speed of light, never mind the fractions of a fraction of a fraction of a second we thing we recorded a particle going faster then light.

Time travel is not possible in the sense of being able to change history.

 

 

How do you KNOW that for sure ? ... You don't.

Time is relative, time does not actually exist. Time is just a perception animals have. Going back in time is impossible, you can not travel on something that does not physically exist.

 

@hoofhearted4

 

If you can move any matter faster then the speed of light you can move a spaceship faster then the speed of light. Obviously it won't happen instantly, but it would still be possible.

 

Other civilizations have had the same amount of time to advance, and possibly more time. Other civilizations also might not of gone through a bunch of the things humanity did before advancing. Reptiles may not of formed and ruled the earth for as long as they did on other planets. There might of been weaker predators where a intelligence species evolved. That or reptiles themselves could of evolved to be more intelligent. Earth does have mass extinction events, what if another planet had a environment where mass extinction events did not happen?

 

If the multiverse theory is correct, then we are not alone in anyway. If it is correct, then there would have been universes that existed before ours did.

 

Warp holes are possible if you can bend space.

Time is relative, time does not actually exist. Time is just a perception animals have. Going back in time is impossible, you can not travel on something that does not physically exist.

 

Time does so exist, its just the measurement of time that is relative. you could easily say there are only 12 hours in a day if you decided to only count every 2 seconds. and as such, since you couldnt measure time in an accurate way, you couldnt travel time. traveling time would require you to state how much time you need to skip (forwards or backwards) but since the measurement of time is a man made thing, skipping 3 days for example, wouldnt mean anything since 3 days is relative.

 

basically im agreeing with you, just changing how you said it.

Well time exists in that sense yes.

[StormTemplar]

You are on a ship and you get past light speed. Why would the Universe be recreated the way it was x time ago for you alone, just because you reached such a speed? Are there save files for previous states of the Universe? Why would the Universe go back in time but not you, doesn't it mean you and your ship would also go back to the part where it passed light speed? Therefore, wouldn't it mean you can't get past light speed, because you just constantly get thrown back into lightspeed when you get past it?

 

Hope that made sense for someone out there :°

[Nintii]

@ Marharth ... The way that I look at time is like this ... Time exists in a capsule, it has a beginning and an ending ... and if you could somehow free yourself from this time encapsulated existance then you would be able to travel both backwards and forwards along it's length.

And it is within this plane of time/existance that all of the known universe exists ... furthermore, it is not narrow but is infinitely broad in it's form and therefore can be approached - (should you be able to free yourself from it's "grasp") - from a vast number of entry points.

 

You need a spacesuit to exist in space, you need a diving suit with tanks to live under water, you need a body to exist on this world and you need time/space to exist at all ... the problem is to pass from this "plane of existance" into what I would call the "... void" (don't ask).

Even if you believe in the afterlife - (please let's not make this a religious discussion) - you would still exist in this time/space plane of existance.

 

You are welcome to argue with my viewpoint, but THIS IS what I FIRMLY BELIEVE so your arguement serves only to entrench your belief and will not change mine.

 

Ok, lastly, within this "realm of existance/awareness/of being" there could very well be other life forms but I haven't met any from another galaxy ... except you of course ... hah, now comes the question ... are you an alien ? ...

And it also answers your Q - Are we alone in the universe ? ... no of course not ... you're here and so are you, and you and you and you etc., etc.

 

And you know I'm right don't you !!!
