Do you think a time machine will ever, realistically be built?

StormWarrior

I would give my life savings to go back and live in the 80's.

Junco Partner

eventually i'd say but probably be a few hundred years

FearDark

No, one wont be invented until 2021, dont ask how I know this.

But if it's going to be invented, wouldn't people from the future already have come back here? They wouldn't be able to keep it secret for long if they did.

Quackles

Not in our lifetime, anyway.. So make sure you tell your kids and grandkids to come back, pick you up, and head off to the 80s.

What I'm holding out for is transporters like in Star Trek. Oh, to be able to teleport...

.22 Lover

No.

Time travel is possible if you can travel faster than light. But since that contradicts all know physics, i dont think it will happen, no.

Yes, that was a serious answer in AH. Shoot me!

Why?

Dartz

Depends on what direction you want to go.

If you want to go forwards, just go very ****ing fast relative to the inertial frame of reference you want to go forward in time relative to.

If you want to go backwards...

Go fast in reverse or something.

RVD420

No, because as said already, time travelling would already be happening....

GLaDOS

I know how to travel through time... at the speed of regular time

Superbus

Go at 88 mph in a Delorean, but of course that's impossible, it'll break long before that.

Overheal

Well let me ask you this OP: Is there a 2-Dimensional device which transports it along 3D space to another 2D plane?

Creed Bratton

Stephen Hawings Universe is on the Discovery Channel in 5 minutes and its about time travel today if you want to find out if it is possible.

ddef

God Dammit! Why did Doc Brown have to be fictional

latenia

It's impossible because time is a physical property within objects rather than an external force. Going back is impossible because it no longer exists and the future doesn't exist yet.

Corkfeen

I built a time machine but it only travels forward, bids start at a fiver....:D

Im time travelling right here right now

at a speed of 1 second per second

send me a cheque and I'll tell you what the weather will be like this evening

Exactly, as the late Daniel Faraday said "Whatever Happened, Happened". You can't go back, and the future hasn't happened so you can't go forward.

They say yes. I say no. Who are you going to believe huh?

Drving a car is like a time machine, look out the windscreen and you're looking at the future
Look out the back window and you're looking at the past

Now, I'm no theoretical physicist (gasp!) but I was of the opinion that time travel was possible in theory, but that the amounts of energy required to send a small payload through time was so vast that it would equal the entire energy output of earth for 2000 years to achieve it? Therefore, although possible in theory, it just couldn't work in practice - it's failure to work in practice being limited by logistics and not necessarily by scientific impossibility.

Don't mind the stupid photo, but this was an ad in some paper in the states years ago.

The day after it's built, some religious whackjob will go back in time, and kill the inventor.

antodeco

I think its a case of when it is invented, it will only be that point that can be travelled back to.

Pherekydes

I have already built a time machine, but I don't know how realistic it is.

Any volunteers? (I've run out of pet mice and goldfish. You'll have to sign a disclaimer)

Capt'n Midnight

I have a time machine. It only goes forward though, very slowly.

watch12

i actually figured this sh#t out before, cant quite recall the details though... it was something along the lines of time being consistent with the outward expansion of the universe, time being a matter of space and distance and all that, however i recall theorising that when the universe begins to retract that time will go backwards...... then the universe will expand again and time will return to a forward motion..... ad infinitum......hmmmm

Stephen Hawking: Time Travel Possible

Astrophysicist Stephen Hawking says that time travel is possible and may hold the key to humanity´s future. His theory is supported by theoretical work by Albert Einstein and more recently by experimental data from the Large Hadron Collider.

Hawking says that over six years a ship carrying humans could accelerate to 98 percent of the speed of light. At that speed a year would pass on earth for each day on the ship. Humans could return to repopulate earth many years later.

Hawking by his own admission is obsessed with time travel and says we can only travel forward in time. In the past he has steered clear of the topic in public lest he be considered a crank but now he is less worried about that possibility.

lets say for second time-travel were possible
1.why would people come back here and now, why not during some interesting period such as dawn of civilisation, or the height of the roman empire, to see if the story of jesus were true , or the 23rd century (time travel might not be invented till say the year 50,000)

2.if someone did travel back in time to 2010 and told everyone he was from the future, how many would believe him

I don't know about anyone else but they didn't believe me, the first time I told them!

What Hawkings is saying was proved long ago through the use of atomic clocks on jet aircraft; I don't see why they have to bring the hadron collider into it. It's still not time travel as most people think of the term-it's more the equivalent of the 'caveman in a block of ice' movie plot.

Why? It was shíte. No internet, no electronics, 6 tv channels, women were less liberal. Ireland living in a sort of shadow of violence, repression and forced perception of inferiority.

I don't think you want to go back to the 80's. I think you just want to be a kid again and you can do that already if you want. Just hit yourself on the head with a brick a few times.

Darksaga87

Go to Cavan, for every second we move forward, they move one second back, So its like 2010 BC over there. The Amish are more advanced than them.

its just like slowing down your experience of time and its effects on you, its technically still time travel but only insofar as we're all time travelling right now

Degsy

I remeber hearing that its possible to go a thousand years into the past but not one nanosecond into the future.

But for something much smaller, the energy requirements would be much less.
Perhaps there are electrons flitting in from the future(s)...
