TIME TRAVEL : Will it really be possible one day?

2015-05-13T18:05:35-04:00

How likely is it that we would actually figure out how to successfully perform time travel? But would we want to? Are there simply things that do not to be tampered with? And what is harder: going back or forth in time to correct things, or living courageously in the present and correct things?

I can't think of an ethical use for time-travel. I'm betting there isn't one, and even if time can be manipulated, it probably shouldn't be.

\\\\\correction\\\\

Scratch that. @ I jumped the gun.

I've thought of 2 that only MIGHT be ethical:

1) 'Freezing' someone with an as yet incurable illness to be cured later.
2) Assuming you are travelling thourgh space, you could modulate your own time so that you could arrive at only moments after you left, as opposed to the great amounts of time that are likely to have passed.

So, I guess to summarize my views, Time-travel shouldn't be used to really travel through time. It should be used to make living in our time easier, and not used to actually alter time or events that have already occurred itself.

Unless you're preventing human extinction, then I guess all bets are off. Okay, I'm a hypocrite. Sue me.

I love these conversations. Time to switch from coffee to vodka and see how this thread plays out. :)

The issue with time travel is that it's either possible and it doesn't break causality (one thing must follow another), or it's not possible.

Work under the assumption that Time Travel is possible, since the other is a moot point. If so, then where are the time travelers? Are they regulated? Is there an investment in energy so high that it just doesn't make sense (likely)?

Remember that the Earth is spinning. The sun is spinning. The solar system is spinning. The galaxy is spinning. If you were to travel back in time even 1 minute... you would be nowhere near Earth. We're moving that fast. Maybe those time travelers forgot to account for the spin of the universe and are Popsicles in some distant part of space?

Either it has always existed or never will.

This is likely our first foray into this lifetime as nobody has come to the past (our present) to warn us of things. So we can't be 100% positive time travel will become a reality. not to mention the plethora of possible paradoxes.

What do we want? Time Travel
When do we want it? Irrelevant.

We would have to create a vehicle capable of containing a live human and traveling close to the speed of light to effectively time travel forward (past is gone folks, sorry), so technology has a long way to go before this will be possible. Maybe someday though...

Mathematically of course it is possible, but at the current state we're in, we would need an exotic object, same with faster-than-light travel.

I believe that time travel is possible, but that it may never be practical.

Consider that the thing you wish to move in time is also located in space. The spatial coordinates, from moment to moment, change. The continent drifts. The planet spins, and our wobbles for a little extra complexity. The planit also orbits. The solar system is moving, the globular cluster is moving. The galaxy is moving. There may be other movments that we know nothing of right now.

And, even if you could nail down all the movements, what is the constant reference point you would use to measure universal spatial coordinates against?

So you send it backward or forward in time. But, I posit, that while it may successfully move in time, there is no reason to assume that it will also move in space. Whatever you shipped, may arrive inside an object, untennably high in the atmosphere or under the water or ground, or out in deep space.

It's happening all the time .. albeit in one direction and one speed .. but its a start!

It is already possible. Some one went back and started changing America back to the stone age.

Just a thought.

I don't think so, Sir. I've included a link concerning the Fermi Paradox.
This issues segues into the reason that "time travel" is entirely impossible for the status of our current civilization.

My daughter is a quantum physics major at MIT and she tells me it may someday possible to move forward but never back. Then she starts talking about Einstien and mathematical equations my simple mind can't understand, I hope that helps

If it is possible one day, it is possible everyday.

I am going to give you the same answer I gave you in the future (the first time I answered this for you), no, it is not possible and anyone who says otherwise is being investigated...

CH (MAJ) William Beaver Time travel into the future is already possible, as proven the Einstein: simply approach the speed of light. Going backwards, however, is another story.

Could be someone's figured this out - only instead of going back linearly, time travel creates a fork in the time stream that's almost, but not quite the same...
