Desert Merchant 07-22-2005, 08:33 PM Is Time Travel Possible? If you think it is/isnt please explain why. I was watching a show that made me believe in forward travel and they proved its possible with high speed planes. but backward travel is a whole other world. they say its possible with the right gravitational force but if you were to travel back it would create many paradoxes such as the grandfather paradox. some people think it creates a parralel universe if it were to happen. Personally I think backtravel is impossible becasue someone would have came back already if it were possible. Let me hear what you think about this...
Shoden 07-22-2005, 08:37 PM you'd need to travel att he speed of light along with control
the time machine needs to be able to travel at light speed and end up at a destination that is inputted by numbers
controlled time travel i don't think so
time travel MAYBE
Cloud No.9 07-22-2005, 09:07 PM it can be done on a sub atomic level. that's it. anything beyond that is so rife with paradoxes and problems.
if you travel at the speed of light your density becomes infinite. distance would cease to matter so would weight. it breaks all rules of physics and would probably end up in creating a super black hole.
so the laws of physics prevents it. you cannot exceed the speed of light. end of. otherwise you become infinitely dense. and the universe collapses.
Gnostic Yevon 07-22-2005, 11:08 PM I think it's possible. There's a lot about time that doesn't make sense. I've been reading one theory in particular that suggest that all possibilities occur in separate places, and that time is actually not all that linear as people suggest.
MsTiffie 07-22-2005, 11:12 PM I believe that time travel can be done but you cannot alter it.
In my opinion I believe that Time travel can be done through dreams. I've often had dreams of "past-like" things.
I know it may sound strange but I've also had dreams of random events that have never happened before, I remember it for a small while then about a few weeks later they REALLY happen and I get a dejavous feeling.
I've had this since I was little and I don't know what it just really scares me. I'd like wake up one morning and remember in my dream I'd see me doing something in great detail like I remember everything about it. Then when it really happens I get a flash back of what my dream was and I feel dejavous. It's creepy but after all that I believe time travel can be possible. Just it's hard to obtain the skills to do it, or it's hard to notice it.
Cloud No.9 07-22-2005, 11:12 PM i'll explain how this all works to people.
the faster you go the heavier you get. this is expotential. as you approach the speed of light you became vastly vastly heavy. thus requiring even vaster amounts of force to push you. to have something go at the speed of light it would require and infinte force to push the infinite mass that would occour. infinite forces are impossible.
but even if you found away this basic principle you are left with one fact. you now have an infinte mass. mass = gravity. lots of gravity = black hole = lots of sucking. infinite mass = omni-suckitude = end of universe. well done if we do manage it we will last for a few nanoseconds.
omnitarian 07-23-2005, 12:04 AM Time travelling backwards doesn't make much sense to me. It's a pretty hefty violation of causality. Still, there are a bunch of zany scientific phenomena that could potentially offer backwards time travel. Even if it is possible, it'd be extremely impractical.
Time travelling forwards is very possible, thanks to the theory of relativity. Just putz around the universe in a really fast spaceship for a length of time, and then come back to Earth and visit your 50-year older twin brother.
Cloud No.9 07-23-2005, 12:18 AM backwards time travel would cause a single all swallowing black hole which would end the universe as it would be infinitely dense. end of.
now going forward in time is possible. it's just hard to comprehend.
gokufusionss1 07-23-2005, 10:36 AM i'm going foward in time right now, just very slowly.

Meat Puppet 07-23-2005, 11:27 AM I went back in time just the other day.
Want proof? Ask me anything that may have happened in the past, and I'll tell you an answer which is probably right.
However, I do not feel confident sharing my methods with people on the internet. Sorry guys.
Destai 07-23-2005, 11:58 AM I read this thread just to see what meat puppet posted. I was not dissapointed.
tomamar04 07-23-2005, 01:31 PM The simple anwser is no.
Time and space are linked, if you change time, you'll destroy the abric of the universe.
Rusty 07-23-2005, 02:33 PM I don't believe time travel is possible, in my opinion the past dead, it exsists now only in memories, history books and the like. The future is tomorrow, if you want to discover tomorrow, you first have to live in this day.
crono_logical 07-23-2005, 02:34 PM I'm currently travelling forward through time at a rate of 3600 seconds per hour :p

Shoden 07-23-2005, 02:54 PM damn you're right but how many seconds are in a day!?
Super Christ 07-23-2005, 03:00 PM Most current theories of the universe allow for it. That being said, we barely understand anything about time so it's hard to say.
Aphelion 07-23-2005, 03:15 PM I don't think so. Maybe it could be possible to "watch" the past in a certain point of the universe, but not participate and change it...
Moose Knight 07-25-2005, 12:13 AM you'd need to travel att he speed of light along with control
that's impossible. The time dilation equation shows that someone traveling at the speed of light expiriences no time, which is an impossibillity.
By a loose definition, forward "time travel" is possible and has been done. In fact people do it every day when they drive.
Sephex 07-25-2005, 07:54 AM I think it might be possible, but if we ever pull it off, it would be done in the WAYYYYYY FUUUTTTUUURRREEEEE!!!!!!!
nik0tine 07-25-2005, 07:57 AM I don't think it's possible to "travel through" time, but it may be possible to speed up or slow down time.
Old Manus 07-25-2005, 02:24 PM Basic rules of physics tell you that you cannot go back in time further than when the machine is first turned on, which explains why we haven't seen any visitors from the future.
edczxcvbnm 07-25-2005, 02:37 PM HELLS YEAH! Didn't you ever read that calvin and hobbes comic? They were trying to go really fast down the mountain in their wagon to achieve time travel and in the end they crashed but they were two minutes further than when they started and traveled!
In all seriousness...why the fuck not? At the present time we have no clue how to do it but there is still so much that we don't know about the universe and how it works. We know stars die but do black holes also die? What are gravatrons and why do they disappear? Eventually I think we will unlock more and create time travel.
bipper 07-26-2005, 01:34 AM Nope no way no how.
Merely going at the speed of light or faster is an illusion of time travel. Because you go faster than sound does not mean you dont make any. Its only relative to you.
Time is all relative anyways. It is not a substance, more of a measure of a constant. If a space ship went faster than light - the material on the ship would still age. It would act as nothing was happening - much like us - we don't get winded in a car going 40 mph, and if you do see your doctor :)
This is all opinionated but seems to be right to me! lol
