Scientist building timemachines?

In people's imagination.... you can travel in space but you cannot travel measurements (meters, kilometers) and time is just a measurement of change.Originally posted by AugoeideS:I didn't imply that we humans can withstand the G force but in theory, this is the only way we can travel into the future. -
How can you get crushed when people on the shuttle in space dont feel any resistance when traveling so quickly?
-
G forces is related to acceleration or change in trajectory...... the ppl on shuttle will feel as if they are pressed into their seats... there is no resistance in space cos the shuttle is travelling at constant speed... no acceleration or retardation of speed so no g force resistance if that is wat u are askingOriginally posted by dark_snowboy:How can you get crushed when people on the shuttle in space dont feel any resistance when traveling so quickly?

In relation to the sun, the earth changes position (around its own axis and revolving around the sun), leading to day and night, and the four seasons.
One complete circular change of the position of the earth in relation to the sun on its own axis is a 'day'.
One complete circular change in the position of the earth around the sun is a 'year'.
One circular rotation of the earth on its own axis in relation to the sun, people conveniently call is a day and the concept of time comes into the minds of humans.
What is 'one circular rotation of the earth on its own axis in relation to the sun'?
It is the [b]change in the position of the earth in relation to the sun.
Space is both a concept in people's head as well as existing outside of people's heads.
That is why people can travel in space.
Time exists only as a concept in people's head but it does not exist outside of people's minds. You can only do time travel in your head (in your own imagination).
When you apply Einstein's theory to 'time' it is not time travel but a slowing or speed up of time. It is not time travel.
For example, if you go into outer space at the speed of light, and it takes you 10 light years to come back to earth, you might find that you have aged one year instead of 10 years wheres everyone on earth has aged 10 years.
When you say that time slows down, what you mean is that the changes has, for you slowed down.
If you imagine that everything slows down and one day takes what previously takes one month, you think you have 'more' time? You think you have now one month instead of one day?
No you haven't! That is because, now, you take 30 times longer to type a post in the computer and you take thirty times longer to get to school. It is back to square one!
To 'increase time, what you do is to increase 'change' in relation to a day. If you do in half a day what takes you previously one whole day to do, you have compared to everyone else, two days in twenty four hours!
Another interesting thought for you to consider, 'If space is empty, a vacuum, nothing... how can 'nothing' exists?' hahahahahahahahaha[/b]
Even if you go faster than light, you are just changing your relative position in space and not in time.
Perhaps, maybe just perhaps, it is possible to see the actual happenings/events of the past, but it will be just like what you see on cameras, video cameras etc. ; can't create a disturbance in it.. -
Actually, time slows down to 0 as you reach speed of light. Since speed of light is never achievable, time always moves forward.Originally posted by AndrewPKYap:You don't go back in time, time (change) slows down that is all....
The hypothesis is...if something travels FASTER than the speed of light, does time wrap around itself and go into the negative? -
One of the more popular suggestions for time travel is through wormholes/blackholes.Originally posted by AugoeideS:I didn't imply that we humans can withstand the G force but in theory, this is the only way we can travel into the future.
Since physics as we know it break down past the point of singularity, anything seems possible. -
Try the piano that xiang lun used to find xiao yu.
-
looking at current technology, this wun be possible at least for the next 200 years.
In theory, anything and everything can happen. this is not theory, this is reality. -
yea heard of it but its nano level. something like atoms or something.
-
Wasn't there an article on Yahoo News back some time ago which says it's impossible?
-
hey i really like xiao yu. she so cute sia. last time i saw a piano teacher she look abit like xiao yu...

Yes yes! Blackholes are plausible...I have a book by Michio Kaku that explains the blackholes in great layperson details but can't really remember (cosmic physics are complex but amazing read).Originally posted by deathbait:One of the more popular suggestions for time travel is through wormholes/blackholes.
Since physics as we know it break down past the point of singularity, anything seems possible.
And now the general trend is accepting the Multi-verse theory as depicted by the M theory...so parallel worlds are probable.
Ever heard of this thought experiment on a guy who have a revolver that have two outcome: it either fire and the guy dies, or it doesn't and the guy lives. So everytime he hit the trigger, the world split into two parallel outcome, in one world he dies, in the other world he lives. Eventually that person is in a state of perpetuality because he is always existing in that particular world where he will survive.
There's so much more perculiarity in quantum mechanics that i find it one of the most interesting subject to study now. -
u know to survive a travel in the blackhole.. u'll need nuthing less than a speed of light becuz anything less.. you'll end up getting torn to shreds by the blackhole's mass gravitational force...Originally posted by deathbait:One of the more popular suggestions for time travel is through wormholes/blackholes.

its not a joke.. a small blackhole is enuff to breakdown and gobble the sun... sounds scary huh... and there are virtually lots of them out there in space floating around...
and oh.. how do we know you might not end up in another dimension altogether? Ever watch "Event Horizon" ? -
u need him -

In a multiverse, where would our conscious be? If I were to shoot myself in the head, would my conscious switch to another "me" in another universe or does our consciousness exist simultaneously in every universe? If so, why aren't we aware of it?
-
Space folds and you pierce a fold to enter another time...etc etc .....too chim for me.
But the best way to talk to the past is call your friend in USA from Australia /SE Asia on the telephone. -
Nothing Is Impossible

this dude will do the job too

Just a question: I thought G force would only exists when you travel through spatial dimensions? If you're travelling through time, shouldn't your spatial location remain the same?Originally posted by AugoeideS:I didn't imply that we humans can withstand the G force but in theory, this is the only way we can travel into the future. -
