Time travel makes no sense

There is a finite length of time that it takes for the light to hit our optic nerve, fire off a signal to the brain, and have the brain interpret it. So really, everything we see, even up close, is in the past. And upside down actually. The images form on the retina upside down.

Last time I thought hard about that, I nearly fell over.

I read a theory that the universe is a hologram (not as far out as that statement seems) so if that was true you could get replays and jumps and skips in time but we would never be aware of them.

It should be written down and adhered to that if a successful time machine is ever created it must be a DeLorean.

That would be the ultimate life imitating art example. :pac:

That's a paradox right there as you'd need one to get the other.:pac:

I have spent the last 10 mins looking at things confirming I am looking in the present, but the minute I confirm that, its in the past....

Ponder this.

You are chatting to your friend in McDonalds. (Why you are eating there is beyond me). You are sitting across the table from him - but you never see him as he his, but rather as how he was a few nano-seconds before that. That's because of the time it takes for the light to travel to you, and then the time it takes for your brain to process the image. It seems instant to you - but at a detailed level - it's not instant.

But yes - I like the sun analogy, because it is 8 light minutes away from us. If the Sun blew up - we wouldn't know about it until 8 minutes later, shortly after which a shock wave would wipe the planet from existence.

1st off if there is or ever will be such thing im pretty sure people would be with us now from the future

2nd
to believe if i could go back a day thats basically saying that there i would be repeating the whole day or that going back in time has rewound time

It just makes zero sense or at least could someone explain it in a way that it might make sense!!

I don't think it makes any less sense than believing that jesus was the son of god and the whole bible fairytale, in fact, it's no less mentally offensive than religion in general.

I think that time travel could be a possibility at some point, although I doubt it will happen in my lifetime.

Some people here must have already half-mastered time travel and got stuck in 1916.

I knew I shouldn't have click back on this thread. Now, my hurting brains are going through a ringer, and I am freaked out about how the hell you know about my secret agent visits to that place.

your using 1 weird made up thing to say another weird made up thing might be true!

Zombie time travelling might happen I guess

I cant handle this, im going to watch X factor to take my mind off it

I always thought Time Travel was one of the blindest of scientific dreams.

Consider time, it is just a man made label. Days, weeks, years, they are just words we made up to give us context.

Travel in time? You might as well try to travel in weights and measures.

We are all travelling in time at the moment, the issue is the speed or the direction.

Travelling forward in time at a faster pace isn't as great of an issue and is theorically possible

You're not doing it right.

Irish Guitarist · 24-09-2011 08:12PM

It's possible to travel into the future but I'm not sure about the past. Astronauts that return to Earth are very slightly younger than they would have been if they never went to space. When we travel further into space at greater speeds it will be possible to travel further into the future.

I always hated and flunked Temporal physics back at Starfleet Academy:(

If only I could go back and do them again.

Saila · 24-09-2011 08:14PM

neither does this

Green Mile · 24-09-2011 08:18PM

It is in fact possible to time travel. There is a theory that does co-incide with physics.
You can only travel forward in time, and it is about traveling at a high speed very very fast.

Basically, if people could travel fast enough, a guy would go into a Pod or Shuttle and after, say 10 years would open his shuttle to find himself 11 years in the future.
He would be more preserved and time on earth would have moved onward while in the process.

It seems pointless to take so long to time travel but it can happen. There is proof that a clock has time traveled. It was synced with other clocks and when it was tested. There was a difference of 0.000000000000001 of a second. It took a year to do this experiment but it showed it could be done.

we are all travelling at the speed of light, through space-time, the faster we go through space, the slower we go through time

I came back in time and fixed your post. I hope I didn't fuck up the time-space continuum again.:(

4leto · 24-09-2011 08:22PM

It is possible, you would have to open a wormhole, say now in a Lab.

Now on the assumption that that wormhole generating machine was kept open in future generations. Then future generations would be able to send messages back to now as in the point the worm hole was open.

But not further back.

Phew there is smoke coming out of my ears.

My name is Professor Mickling. I'm a time traveler from the year 2476. I came to this time period to give a lecture in Trinity College. Anybody wishing to attend, its in the Walton theatre on campus, last Tuesday at 8pm. Hope I saw you there.

I missed it by five minutes.

OP, never heard of hypotheses to maintain some amount of temporal consistency?

Sheesh.
