Warp drive? Would we be able to go both forward and backward? Future doesn’t exist yet?
if we go back could we change things? if yes, who’s changes would stick or would things change constantly.

what do you see would be the problems if we could time travel?

could we go back to Eden? ahead to the 2nd coming?:eek:

mind boggling stuff.:confused:

do you think it will ever be possible?

It will not be possible.

Time is a result of entropy, which means the world of the past no longer exists. It also means that no one can travel from “the future”.

but if time slows down as you approach light speed, that presents possibilities, no?

why/how is it tied to entropy?
 
I realize that this answer may not satisfy, but we actually experience it right now, during the mass. Heaven is opened to us. As with the shepherds in the fields surrounding Bethlehem, the heavenly host surround us. We are at Calvary, we are in the upper room. And, there is more drama involved than any cinematic event.

Yes. All you have to do to travel into the future is hop into your spaceship and do laps around the solar system at, say, half of light speed. Then land on Earth again, and you’re in the future. See the twin paradox. This won’t work backwards, so you better enjoy living in the future. If you go fast enough, you’d reach the Second Coming in your lifetime. The problem is getting enough energy to build up that kind of speed. Maybe if you use a planet or two for fuel…

I think I read that you can travel back in time if you fly up to a huge black hole. Time will travel backwards after you cross the event horizon, and before you get squished. You wouldn’t be able to do anything useful though, being inside a black hole.
 
dont waste your time with such thinking. it wont ever be done. and i can be certain that god would disalowe it.
 
Time travel is possible. Every day I travel into the future. I am there now, or at least I will be in a moment! 🙂

Linear time, as we experience it, is the result of entropy cooking off inside our heads and bodies. What we perceive as time is entropic change, and all processes – such as moving your body – are powered by entropic change.

The only difference between this world and the world of the past is that entropy has converted that world into this one. Entropy is irreversible, so that world no longer exists.

Time is just an illusion. Neither the past or the future has reality. They are figments of the imagination.

The present doesn’t really exist either, since it is infinitesimally small point (i.e. the ‘now’ moment is a point without temporal extension).

Since time is not possible, neither is time travel.

Also, refer to Parmenides. Nothing which changes exists. Augustine- “Only that which is eternal truly exists.” Therefore, all that exists is actually eternal, insofar as it exists. The only reality is a single, infinitely simple sphere, which does not change. Time is a measurement of change. There is no changein the truly existent. Therefore there is no time.

Therefore, time travel is not possible…

That’s…deep. But we are not at those events. Those events are with us. To clarify, look at it this way. Every time the Sacrifice of the Mass is performed, a spiritual thread (or, perhaps, world-line) reaches from the Crucifixion through spacetime, joining the Sacrifice at the Altar in the present day to the Sacrifice 2000 years ago at Calvary. They are precisely the same event on a spiritual level. Physically speaking, the priest is merely uttering some words over a bunch of wafers and a cup of wine. But spiritually, it is the very same Sacrifice at Golgotha which opened the gates of Heaven to us, the Sacrifice which transcends time and space.

As to physical time-travel, travelling forward has occurred before. In fact, whenever I move, I travel through time faster (forward) than someone at rest. Travelling backwards…well, that’s this thing called the Novikov self-consistency principle. Basically, it postulates that if you travel from point B on timeline T to point A (which is before point B) on T, and do random stuff to diverge T into T’, T = T’. You would have travelled from a universe which you have already changed. So nothing changes when you come back. If this is true, this means that time travel backwards is not impossible, because all the paradoxes would be resolved, but this form of time-travel would be practically useless, except for retrieving information from the past (and, I dunno, trolling Protestants; bring Christ here and show 'em who’s boss. But I’m sure God’ll do something about that. Or maybe that would be the Second Coming. a hardcore Catholic physicist trying to prove a point. But I digress). And also, it’s possible to travel faster than light, using this (real life) thing known as an Alcubierre Drive.

No!!! Not the Alcubierre warp drive (AD)! What a cruddy piece of ‘science.’ It is not at all real life, it is only a mathematical hypothetical. To ‘make’ the AD, one needs to have exotic matter (which does not exist) and force it into a specific geometry that would make the drive. The link you give states rather clearly that it is “speculative” and has the insuperable problems of
The amount of energy required is unobtainably large, there is no method to create a warp bubble in a region that does not already contain one, and there is no method to move from the warp-bubble once having arrived at a supposed destination.

Discounting our own second-by-second progression forwards in time, there is no way to time travel. It just cannot be done.

Time is God’s construct that applies to man - for His purpose. When we seek to master or control it, we are encroaching on God’s power and authority. Since all that occurs in time is pre-ordained by God, our meddling with time imposes our will in opposition to God’s will. And, one of the few things that we do know is that our will is opposed to God’s will. This is perhaps a parallel to Genesis 3, where knowledge of good and evil was God’s possession, and man violated it.

As to the mass, our sacrifice is offered to the Lord in unity with His eternal mass that is offered in heaven for our sakes. We are members of Christ’s Body, and so may offer our sacrifice through Him to the Father. We cannot separate the mass from any portion of Christ’s eternal sacrifice, but we join it at various points in our life. In that sense, it is time travel.
 
Time travel is not possible. What I think may become possible is viewing the past through a device.

Time travel is illogical.

If you travel to the past, would you meet yourself? Then there’d be two of you. But there is nothing in your memory about meeting yourself. This is illiogical.

The same goes for traveling to the future. Would you meet yourself? etc

While time slows down as you approach the speed of light, it is not time travel. It is just a slowing down of your aging. When you returned to normal speed on Earth you would be younger than your kids, but you would be in the same time. That’s not time travel.

( Travel at near light speed is impossible for a human body, presumably in a spaceship.
It’s impossible from physics because of the enormous amount of energy that would be needed. Could a hundred trillion megatons of energy be given to the human body? How would you do that?
It’s impossible practically because if you collide with anything, even a grain of sand, it would be disastrous. To keep things out of your way, you would have to spot them and disintegrate them with a laser beam or something, but you can immediately see that you could not do this unless you were traveling at less then half the speed of light. Actually, it’s believed the fastest spaceship by the most extremely advanced civilization could be no faster than ten percent the speed of light because of this need to get debris out of the way, and a more realistic ultimate speed might only be five percent light speed. )

Somebody, possibly Isaac Asimov, wrote a short science fiction story about that.
A scientist invented a machine to pick up “M-rays” that showed scenes from the past. You could see Ceasar conquering the Gauls etc.
The government kept the device secret. But of course, some idiot got the blueprints and published them to the world.
Then people realized why the government had been keeping the design secret. When does the past end? A nanosecond ago. Now that anybody could get his hands on one of these machines, they could look into what you were doing one second ago, including the most intimate moments. :eek:
Welcome to the goldfish bowl! 😊
 
It is impossible.

Suppose we were to go back in time and go back far enough, enter the Garden of Eden and tie up Adam and Eve so they wouldn’t fall.

I’m sure God would not want that, as that would stop all suffering in the world.
 
Considering no one has ever come “back” from the future, I’d say it’s not possible, or it would have already happened.

😉
