Physicists Just Came Up With a Mathematical Model For a Viable Time Machine

Travel in a circle of time, like Quantum Leap - "Oh boy!"

You can't say 100% that time travel doesn't exist...why you might ask. Because even though it hasn't been invented yet, doesn't mean it won't be. Therefore someone can come back from the future with a time machine to our current time, then yes time travel would exist in our time...

Because even though it hasn't been invented yet, doesn't mean it won't be.

Paradox afoot.

Ya if it can be invented then it already has. Time is either a river or a spreadsheet.

Does it really exist, this destroyer, time?

That is a great question. Maybe it isn't an actual thing in the sense that a brick is a thing. Or gravity is a thing. Maybe it is just a useful concept for describing a perception. Kinda like using the word red to describe a color. Red isn't actually anything, it just gives us a reference point for discussing a detail of observation.

And time isn't the destroyer, entropy is.

Time is the same as creation.

You can play and toy with your won understanding of the mechanism. I've started to do it recently. Time is more akin to a vast loop, rather than a straight line.

I've also noticed time repeating itself at several year intervals. Similar things happen in my life that are only divided by years and not context or lesson. Time changes but only with the individual mind. The force behind it remains consistent, malleable and to a degree very personal.

Well according to relativity time isn't a universal constant. Experiments have even proven it.

Time is entropy. ;)

Without space, there is no use for time. Without time, there is no meaningful use for space. Time is the great mover unmoved. If the universe is a rollercoaster, time is the track. Is it actually a measurable thing? Eh. Humans created the idea of measuring time relative to our solar system

Humans created the idea of measuring time relative to our solar system

Agreed.

There'd be serious Government intervention of certain people if they had the technology..

Like a Trillion dollar/year defence spending bill that has nothing but public failures yet continues to produce millions of pages of classified info every year.

Perhaps a Religious Institution which has been involved in education and the majority of scientific discoveries over the last 500 years, also one of the largest land owners with its own banking empire. (RCC).

The only thing that is unlikely is the paradox. A time loop would happen in a paradox situation. Regular travel backwards would create new timelines. Which themselves may be paradoxical in the grand scheme of the universe. Suggesting any interaction with future civilizations denotes the existence of a present time loop.

Now look through history for signs of people or who/whatever coming into an earlier time and messing with the people or politics in it. Keep in mind these people would have god-like powers to the natives.

This would make sense if the future is probabilistic. QM experiments suggest this. If I were forced to make assign a likelihood I'd probably go with this.

The loop and the paradox are the two weakest elements and hard to rectify. Unless there are multiple systems. For instance the beginning and end exist and cannot be changed (loop), but within that only the present exists, allowing for probabilistic progression from the beginning to the end.

Time travel can be real... but you can only go forward in time and never backwards.

Depends if we live in a probability matrix or not. If QM experiments are correct the future doesn't exist. The past would be imprinted into the universe. Meaning travel to the past could happen but the future would always be a probability of what is the current time. The singular point of conscious being in its current state.

"The whole thing goes: The future's not set. There's no fate but what we make for ourselves."

That is true. The future is never set. But the past is set. That is why you need to go back and make a copy of the past if you are going to try to customize it and live in it. It is never the same video game when you "do-over".

If you went back in time to the exact same place you would be in space. Earth moves, the milky way moves, everything moves, there is on place to set the reference coordinates. Only if this a simulation can time travel (system reset) take place imo.

But when you play a YouTube video clip over and over, you always find yourself in the same place at the same time, every time. A recorded video preserves time. A time traveler travels to preserved time. As long as you have an image or an object that existed during that time, you can go there. But it isn't the same past. It is a copy of the past.

I am currently traveling through time.

At the speed of regular time!

Time travel won't be practical w/o a vehicle capable of interstellar travel.

Assuming "time travel" is Point A to Point A through time, the planet and solar system itself will have moved hundreds of thousands of miles away.

You can't ignore the solar system careening though the void at breakneck speeds.

This assumes we need a "vehicle" I'm not so sure of that any more.

You don't and I will explain why you don't need a 1967 Stingray Corvette.

Take a big cloth. Now make a pocket. The lip of the hole is very light and the bottom of the pocket is very heavy. We call this a gravity well and there are something called Gravitons that shower this pocket cloth pulling everything down. Now run your finger from the lip to the bottom of the pocket. Let's call this a ray of time, movement and distance. That's what time is. It is just linear movement as a result of gravity.

Now make another pocket. You now have two pockets chasing each other like two sharks in a whirlpool.

Call pocket 0, World-0-Time-0-2063 Call pocket 1, World-1-Time-1-1999

Now bring the 2 pockets together. Imagine walking from pocket 0 to pocket 1. This is time travel.

Now you probably do need a car because the currents of time are very strong and could tear you apart. If you jump off a bridge from a great height, you are likely to die. But if you're in a car, at least you're a little protected from the impact of surfing the ergo-sphere of the two pockets.

There. I just explained time travel.

You're missing some labels there.

World-A-Point-A to World-A-Point-B suggests that you are folding space, time, distance, movement. That's Warp Propulsion, Teleportation, whatever.

But time travels is World-A-Time-A to World-B-Time-B.

They don't understand the technology yet. To travel in space is to travel in time. Faster than light means that you travel faster than change. It means if you traveled 40 light years away but traveled 73 light years per hour, you would be able to see the effects of the nuclear bomb on Earth as you would be at a point in space earlier than you were created. Faster than light is faster than creation. You could travel to that place but you would get back 146 years in the past.

THis is why faster than light travel is a bit complex because you are warping the space around the vehicle so that the vehicle itself is the only thing aging.

If time travel ever exists, it always has.

Time is an illusion.

No dude, time travel is 4 real. When I go to bed at night, I shut my eyes. When I wake up, it's the next day! You can't make that up!

But time is man-made, is it not? We came up with the concept of time, it wasn't a constant when the universe was apparently created. So, we could very well be going BACK in time, by the Universe's laws. Just because the date today is June 30th 2017, and tomorrow will be July 1st, 2017 that doesn't mean we are moving through time, heading for the 'future'. WE created that.

Honestly? Where is your proof that time travel doesn't exist.

Traveling forward in time is time travel and that absolutely exists.

Furthermore, we just proved that two black holes can orbit each other. So I guess we don't know about nature as much as we think we do.

Travel in a circle of time, like Quantum Leap - "Oh boy!"
