You Can't Travel Back in Time, Scientists Say

Does coexisting mean existing but separate or together? In other words, is the past as undetermined as the future?

I'm also wondering if the terms "separate" or "together" would even have the same meanings as we generally use them. I mean, technically, if "All is One," then there are connections. But how? What?

They would exist seperately until such time as interaction took place?

Makes me wonder if something was changed in this timeline, would we even know? if that makes any sense?

Lad, if I knew that I'd have a Nobel Prize on my mantle...

It never hurts to ask. 😆

You mean in regards to following the laws of physics? Quantum mechanics? I remember reading something on Quantum theory and quantum interference but then my brain needed a reboot

😂 just make sure theres a © on the end of your answer if you have a revelation.

You know i was watching back to the future parts 1 2 & 3......and it made me wonder.....how did michael j. fox get Parkinsons disease?........Time Travel?

No, all that Plutonium coming out of the Flux Copacitor really f*cked him over.

They didn't go back in time. They just went to a new set. 😬

This is a theory.

We can't know until we can actually obtain that much power. srug

if your mass is imaginary, meaning you are a tachyon, then theoretically you travel faster than light and backwards through time.

Michio Kaku.....Great man, I respect his opinion a ton. Interesting read, is this the general consensus amongst the science field?

we learned about time travel last year in my science class. My teacher said pretty much all of this. Apparently, the first people to land on the moon aged .ooooooooooooooooooooooo(lots of 0's)00001 second less than the people on earth. Pretty cool. You should check wikipedia for the time travel twin theory, or something to that effect.

Physics has all kinds of neat and wonderful little terms for how the universe seems to be all interconnected, eg, nonlocality, the implicate order, the universe-as-holograph, and as I mentioned in a prior post, the quantum-cosmological stance of assigning the universe as a whole a wavefunction. How are the different wavefunction-states of an electron connected? With the universe as a whole, perhaps it's the same sort of deal.

Excellent i'll check it out, i remember a good series in 2000AD called Zenith that dealt with the subject of the multiverse 😮‍💨

time travel into the future actually IS possible

It is, I'm going shortly.

Can you bring me back the new/old Playstation 10 or failing that a T-800 for home security

I can't go back. You're here now anyway so it doesn't matter.

Just leave them behind the wheely bin

That article brings us back to square one...

Some scientists say we can, others say we can't.

One way to exploit the general relativity to travel to the past is the wormhole thing. Wormholes that connect two different times are only possible if negative energy exists.

Negative energy is not something so weird, it appears in relativistic quantum mechanics. The only way to create a relativistic theory for quantum mechanics needs the concept of negative energy to make sense. This happens because there will be a negative square root when you try to calculate the energies for a given problem. So you will always have a positive and a negative value for the energy.

But I don´t know what happens in quantum field theory. I think that those negative energies where eliminated in someway by what I remember, but I´m not sure.

I think travel time to the past is logically possible if we are talking about parallel universes and those temporal paradoxes are not a problem anymore, but we still don´t have a method to switch between universes. I mean the many world interpretation just makes time travel to the past a logical possibility but it doesn´t say what we should do.

I believe that if its is really possible to create wormholes connecting two different time regions then perhaps entering one of them would be a way of switching between these universes.

That's an interesting article. Kind of funny that some scientists believe that they can travel into the future, not really having an understanding of what time or the past is. I mean - for all they know we could be living in the past right now. Or perhaps there really is no past, present, or future, and time is just a limited and controllable quantity like any other that makes up this life.
