Im board so, lock this if it sucks, SORRY.

SOme people say that you could only travel forward in time, but then the future would be altered due to your absence. If you went back in time, you woluld mess up the future. Heres some sinerios:

~lets say you go back and you accidentally show someone in the past about lets say a phone. Then they would be intriged and the phone might be introduced earlier and invented by a different scientist/scientists altering the future/
OR IT COULD CREATE AN ENTIRELY NEW TIMELINE

i created this thread to discus whateva about time travel

I want to travel back in time and tell myself how beautiful and sexy and perverted I got in the future, oh and buy myself some snacks.

There is technically a way to go back in time.

The human brain HAS the ability to control time dimentional speed TEMPORARILY in a LIFE OR DEATH situation or what you can TRICK your brain into thinking is life or death. It has been proven by science but has also been proven is not controlable and anyone who hears it normally thinks it's bs and doesn't really pass on the word. :/

Anyway, lets go deeper into what is not proven science but theorie science.

Theroretically, there are SEVERAL dimentions. knowing you can cross a shared dimention with time control instinct. It suggest there could be dimentions that are not shared with our current one but are exactly the same as this one. Whats the catch?

This dimention you cross over too has SLOWER time frames then the one we are currently in, therego if you cross into it you are actualy going back in time to the present. You are capable of seeing your past self because they are not yet in the time frame where they cross over yet. However in this situation your body would most likely die from extreme enviorment changes.

It's just a theory backed up by proven science that people think is crazy tho so yeah. It was proven when scientist studied certain firefighters inside of a burning forest.

~~~~~~~~~~~

as for the situations. if you showed someone a phone it wouldn't matter, you actualy still in the present no matter what you think. There is no "past" time will always continue going forward, there will be no new furture, if you kill a dino in the "past" a dino will be dead in the furture and so on. it's just a for of imagery. Your seeing what was but is now.

WOW you sure know alot

While studieing human phycology I picked that up, I then made my own theorys based off of it.

I actualy have my own idea of what a "dimention map" would look like, it has 4 squares all together and a circle in the middle to represent multiple dimentions and a joined part where they all share something.

I'm not into strings theory but that's some interesting stuff...

I've read somewhere that everything that has ever happened should eventually happen again in a similar, not exactly equal, context. Sometime, somewhere in space, there will be another person like me writing this same thing. So I might just fly there on a spaceship and advance in time too. That way I am traveling to the past... sorta.

That is always happening. Think of your username.

Fxie wanted to name her username Fxy, that was already taken, prooving two people can do the same thing somewhere out in the world. It could very well be there is a planet identical to earth, is there? Not likely tbh, earth is about the only planet that supplied life that know of (not saying other planets CAN supplie life) if you don't count mars which has germs on it and in about 90 billion years, will most likely evolve into what would be like us.

Considering how big the universe (not just the known universe) is, isn't it highly probable there is a planet similar to earth. And this is within present time. Now if you extend the scope to thousands and millions of years in the future, it's even more possible that eventually a planet almost identical to earth will exist.

But again, that is theoretical, and I think it's purely mathematical. It has something to do with probability and quantum mechanics, but I don't know much about the latter.

edit: looks like this is the theory I was talking about [url]http://en.wikipedia.org/wiki/Poincaré_recurrence_theorem[/url] in case someone is interested e.e

There was some theory about combining particles in every possible way and the possibility of two or more similar particles co-existing. Meaning, there could be another you in certain parts of the universe..if you traveled there far enough.
Another theory about the existence of multi-verses..if you thought the universe was big enough, there's always something bigger.

All this theory about time travel is bollox. Things move on and is impossible to stop/revert them. Light travels from the sun to earth, we don't send it back to the sun, do we?

The thing about making time feel slower that Chris mentioned, is quite interesting. But I believe it falls more on the fact about the brain being able to process things faster at a life-death situation.

Actually, it's highly improbable that there /isn't/ a planet similar to earth, the universe is infinite, it's always expanding, and we can't even begin to comprehend how big it is.
This pretty much proves that there is life somewhere in the universe, since it never ends, there will eventually be life.
Not saying that life would be intelligent, like you said, it could be cells like on mars.
Well that was off topic.

I agree with Holo on the time travel thing - it's bullshit, you just cannot go back in time
As for going forward in time; go to sleep ;)

There are many theories out there, time travel could be a theaory, or it could in fact, be real, for our brains to unlock later, we use less than a third of our brain so, you never know

What if you went forward in time and shot yourself in the past? Does your existence just reach a stop? What if you shot your dad 2 years before he met your mom? I guess this won't be bad if you were made without a dad.

Can I just say it is very plausible that there are no planets similer to earth. Yes the universe IS infinate, but at the same time whats in it is not. A planet cannot be made, only destroid, and if there was a plent made, were all dead because it's something called the big bang theroy, planets are saposed to be aftermathh of this bang. matter compressed together and destroied creating. So basically, if you ever see this bright light (huge bright light) our universe is about to be recreated. (destroided then rebuilt in the after math.)

So what i'm saying is because I planet cannot be made and theres a certain bondry point where you stop finding planets. It's not likely anything out there is similer to earth. The universe is infinate, but you will not see something for a long time if you go out there and if you go far enough out, you won't even see stars.

My ol' pal Stephen Hawking doesn't think travelling back in time is possible due to the paradoxes it creates. However time travel forward is very possible if travelling fast enough, and also even occurs naturally due to the fluctuation in time that objects with large masses create (black holes being a good example). [http://en.wikipedia.org/wiki/Gravitational_time_dilation]

Also many scientists believe there is a boundary to the universe. Holographic principle relies on there being a boundary in which the coding of the volume of the universe is stored. The universe is however always expanding (for now anyway), if that's what you meant by infinite.

Also there has been equations formulated that estimate the amount of extraterrestrial civilizations in the Milky Way galaxy, and it has been applied to the universe too I believe.

http://en.wikipedia.org/wiki/Drake_equation

It is largely based on conjecture though and I don't really buy into the results.

Life is out there yes no one can denigh it, theres life on the next planet to us (germs/bacteria are considered life imo) it's the fact that we are talking about interligent life. I will not be surprised if we ever find out we are "alone" when it comes to smarts. Or just, very very low on capcity. (means theres like only 1 other thing out ther thats inteligent like us) and in the end it wouldn't probally matter. They will most likely be aliens that did not devolpe OUR vocal cords making them incapable of talking to us in a way we can understand. (well there goes your star trek fantasys) Aliens that are made up of their own stuff, may even consider us a threat and what da ya know "hey whats the in the sky?" "*spaceship* IMA FIRIN MAH LAZ-BLAAAAAAAA" war breaks out. And knowing our earth and how low it is when it comes to materials compared to other planets, we would mostlikely not have plasma weapons, not have lasor weapons, and not win the war (aka human/earth extinction)

Space and time are a very gory sad subject isn't it? :D

That's a very egocentric way to see ourselves in space.
How many stars may be out there? How many possible planets may they have?

Wikipedia a dit :

Stars are not spread uniformly across the universe, but are normally grouped into galaxies along with interstellar gas and dust. A typical galaxy contains hundreds of billions of stars, and there are more than 100 billion (1011) galaxies in the observable universe.[78] A 2010 star count estimate was 300 sextillion (3 × 1023) in the observable universe.[79] While it is often believed that stars only exist within galaxies, intergalactic stars have been discovered

huh, 300 sextillion? I can't even imagine that number physically. And that's just an approximate value, only in the observable universe.

Of course, it IS possible that there's no other planet like earth where intelligent life is viable. But I don't think it's as "likely" as you said.

Even if there's no other planet similar to earth. Life may still be possible and there's no guarantee that we are the most developed species in the whole universe. Again, it's still "possible". But why think that way, as I said I find it quite egocentric to see ourselves as such. Should an encounter with an unknown alien species occur, perhaps we'll be the ones to go -IMMA FIRIN MA LAZOR, and also invade ur planets-, after all; it's politicians who make the decisions, not scientists.

There may even be non carbon-based life somewhere in space. We'll never know... (?)

hi i like to talk about pseudo-science without even knowing how to spell related terms

I'm sorry Mousechris, but a lot of what you say is complete and utter bollocks with no evidence or sources to back it up. Life on Mars? Since when? It would also make your argument more believable if your spelling and grammar were more comprehensible.
There is no evidence to say that travelling through time (forwards or backwards) isn't possible, and travelling forward in time is very much possible as already explained by Kenjit (time dilation).
There are many theories of travelling back in time, even Stephen Hawking suggested that it is quite possible that time travel might only be possible in a region of spacetime that is warped in the correct way, and that if we cannot create such a region until the future, then time travelers would not be able to travel back before that date. Which would explain the lack of time tourism from the future. There is also the Novikov self-consistency principle which theorises a solution to time paradoxes.
A note on the way we perceive "near death experiences"; time does in no way slow down, it is merely our memory of the event that makes us believe that it was. The extra adrenaline produced in this event may also improve our response times adding to the perception that time really has slowed down.

Spelling and grammar have nothing to do with evidence. It's my own theorys if you don't want to accept them then don't but theres no reason for you to yell out their wrong because i have bad spelling and grammar

scientific theories aren't to be accepted unless they've been adequately evinced (btdubs yours haven't)
