Hmmm is it a good book i might get it?
I believe Time travel could be real actually this is more what i believe
Reality could be ****ed with. Scientist will probably screw around with reality and matter and all that good shit sometime in the future.
I do believe if you were to go into the future or tear through reality or something weird like that it'd have to involve moving very fast.
Time travel is possible. Sit there and you are moving into the future second by second. 😛
The speed of light is the fastest you can go before moving backwards in time. The only particle that scientists believe can do this is the Quark, which even then, is a theoretical particle. To jump forward in time, you'd have to create a rift in the 4th dimension...which isn't going to happen. Ever. Humans will be extinct by the time we figure that out.
Or, you could just take a plane to a different time zone on earth. Thinking about the time difference freaks me out sometimes. I can watch a cartoon set a specific time here on the east coast(US) and then I'm talking to someone 3 hours later who is on the west coast, and they are watching the same cartoon I saw 3 hours ago...wierd. It's cool though.
I don't think anyone can say for certain, it's a paradox. If I were to go back in time and kill my Grandfather, how could I have existed to kill him to begin with? Heh, just watch Futurama. Anyway I don't think it's something that I will have to worry about in my lifetime.
And just on the aliens topic. Has anyone ever thought that human beings may be the most intelligent or technologically advanced species in the universe? Heh, I certainly hope not but it is a possibility. 😛

But if you 'zoom' out of h.s., where would your knowledge come from? Would the knowledge you wold have learned in those years be there when you zipped back into reality: billions of tiny neurons spontaneously create themselves in the branches of your brain, and all the memories you had during this time just become inserted into your mind? How would this work? If you time travelled into the future to skip h.s., how were you there to acquire this knowledge all through h.s. to get your diploma if you existed out of the realm of time? Food for thought, eh?
Ok I have two theories first of all I believe travelling back in time is possible but going into the future is not.
I am first going to start with travelling back in time. Most people think that by travelling back in time you can go to any year or day in the past. I believe that to be impossible the reason for this is because we have not yet invented a time machine
Ok let’s say today I make some sort of time machine and I turn it on today. What if next week if I used it I would only be able to travel back to the time I switched it on!!!
So I think in 50 years time someone will invent the first time machine but they will be only able to travel back to the point they switched it on.
Ok Travelling into the future I mean what does it mean I mean how can we travel into the future if has not been invented yet I mean travel back in time is ok because its already happened!! They only way to travel into the future would be if my body was frozen and in twenty years time I was awaken to me it would seem like I had travelled into the future.

the problem with this train of thought ash is that time is not linear...that is concept we (man) invented in order to allocate certain moments of the day...a way to use as a point of reference for a moment that has happened beyond the point of now, our present which we've labelled the past...time travel IS impossible because it goes against the concept of physics even at the quantum level...and einstein's theory though i'm somewhat vague on that is the faster we travel from point A to point B, the idea of time slows...and the closer we get to the speed of light it slows even further...
so if you do build a time machine...it would be a machine that travels from point A to B and not B to A...AND it must therefore travel faster than the speed of light...the results would be that time for the occupants would slow to considerable degree while outside the machine time would continue as usual and normal...everything would age quicker other than you...time travel to the future is possible if we can build a shipt that can surpass the speed of light...but then we'd have to overcome the possibility of not regaining our solidity...anything going that fast becomes energy matter...
but what if you could travel back in time...would it really be that?
because from your perspective you're still moving forward in time but now in the past...so the past becomes your future
time around you could be theoretically altered but your timeline frame could not...it will always move forward even if you could travel back to a point in time in the past...therefore you're always moving forward in time...
today it's 2004, you want to travel back to 2000...an hour later you've accomplish it, you're in 2000 but an hour ago you were in 2004
so your future has become the past and your past the future...a conundrum...
i even confuse myself
Time travel?
Sorry to piss on the bonfire a bit here, but there is no way that backwards time travel is possible.
Ever.
Aside from the "Grandfather Paradox" and all the rest of it, there still remains the very basic fact that if, at any point during the entire history of creation, anyone, no-matter who, invented a time machine, all time and all history would instantly be combined into one big lump, right at the first millisecond of the universes existence. People would come and go, flitting between times, and the start of the universe would be just as technologically advanced as the end or, indeed, the middle. Don't think that it "will happen one day" because, believe me, if it was you'd know all about it.
Some might say "oh but governments and people will cover the time machine up and there would be very strict rules". You must remember that we're dealing with the whole of time here: right from the first to the last seconds of the whole universe - several billion years. No government could possibly keep it hushed up for that long, and, if it were possible, it would get rediscovered more than once anyhow.
Forget "people coming back to see you", if time travel was ever going to happen it would have already done so.
Now forward time travel is different. We are doing this all the time just by being objects, and ones "journey through time" is supposed to be that much faster when travelling at great speeds. This is so much in evidence that even satellites orbiting the Earth at God-knows how many miles per hour gain a few microseconds each week. Their internal clocks are moving so much faster than clocks on Earth that they need to be updated regularly so that the damn things don't get lost.
So my opinion is this: time travel backwards? Never. Time travel forwards? Possibly, but only dishearteningly slowly.
But I may be wrong.
I have always thought about time travel and preventing and changing choices and decisions would be kind of scary in some ways because the slightest decision could change several peoples lives.
Example: You know how sometimes you think about something like if you go to the grocery store and you get home and think danm I forgot to get some milk I should bought some. Now lets say that for whatever reason you want to go back in time for something small like this just so you can do something you think you should have done before. Now what if you went back in time to the grocery store and decide to get the milk you forgot to get except by doing so you made your stay at the grocery store five minutes longer and when you finally get out of the store there is a shooting in the parking lot outside and you are caught in the crossfire and die. Then lets say you were a father who supported your family with everything they had so in result of your death your family become homeless and now have to live in the streets.
The reason all of this happened was because you decided to change something small you thought would make no difference in changing.
time is an imaginary function. The past does not exist except for inside the human brain. The past is a part of the human imagination, same goes for the future. You can never be in the past, and you can never be in the future. You are always in the now. The present. Most people spend their lives worrying about time that does not exist in any real sense, only the immaginary. Most people spend so much time worrying about the past and present they never appreciate the present and what you are experiencing at this exact moment in time. Dont worry about time travel machines, worry about who and what you are right now.

I was just hypothetically speaking.
It's not imaginary, it's the 4th demension. There are 8 other demensions that we can't even percieve. Would you call those imaginary? Just because We can't see it, or hold it in our hands does not make it imaginary. You are physically passing through time as you sit there in your chair reading this. If time did not exist, neither would we.
Arachnoidfreak> Ahem. (Your local physicist clear throat). We know today of four dimensions. Three spatial (back-fort, left-right, up-down) and then time. String-theorist speculate, that there are another 7 tiny, curled up spatial dimensions. But no one knows for sure – String-theory hasn’t been tested or validated.
But time is indeed NOT an illusion. It’s just another dimension with special properties. The past does indeed exist. If we look at the sun, we see it as it looked 8 minutes ago. When we look at Alpha Centauri we look 4,3 years into the past. And with the Andromeda galaxy it’s 2 million years into the past.
So saying time is an illusion is nonsense.
Time is required when change takes place in the three spatial dimensions. It’s the one dimension we move through constantly, although Einstein proved that we can move through it with different velocities depending on speed in the three spatial dimensions.
Time-travel? It’s possible to travel into the future faster than anyone else. That’s Einsteins time-dilation. “Just” move close to the speed of light and you’ll arrive tomorrow faster than the rest of humanity.
But into the past? What about the famous grand-father paradox?
There are two solutions to that. One is the Alternative History hypothesis. It states, that if we travel into the past and have free will, every single choice will create an alternate reality (like Back to the Future II). But where should the energy for these creations come from?
Then there’s Novikovs Consistent History approach. It says you loose free will, if you travel back in time. History happened, and you can’t change it – even if you try.
Personally I think Stephen Hawking is right :”The fact that we’re not knee-deep in tourists from the future is empirical evidence that time-travel is not possible.”
