“Einstein’s Theory of Relativity says that time travel is perfectly possible — if you’re going forward. Finding a way to travel backwards requires breaking the speed of light, which so far seems impossible. But now, strange-but-true phenomena such as quantum nonlocality, where particles instantly teleport across vast distances, may give us a way to make the dream of traveling back and forth through time a reality.
Step into a time machine and rewrite history, bring loved ones back to life, control our destinies. But if we succeed, what are the consequences of such freedom? Will we get trapped in a plethora of paradoxes and multiple universes that will destroy the fabric of the universe?”

I have a very simple idea why you cannot travel backwards in time. If you could, there would be an infinite amount of time for someone to do it and let us know. Since that hasn’t happened, it can’t be done.
I’m no expert but I think Morgan has a wormhole on his right ear.
Awesome. Although it time travel backwards in time were actually possible, wouldn’t we already know about it?
I do not believe our physical bodies will ever be able to but I think the ingestion of intravenous DMT can allow our consciousness to.
I’m extremely sceptical, I watched a Horizon show with Brian Cox on time (starts here: http://www.youtube.com/watch?v=km89X8zoJH0) and I read too that another way to think of time is as change in entropy, we naturally experience it increasing because “experience” is a result of chemical reactions that are a part of the increase of entropy. Therefore you can’t go back in time, because that would involve reversing entropy on a universal scale. Whilst preserving your own state, mind you. I just don’t think it’s scientifically respectable to blithely suggest you’ve found a way to travel back in time.
Although…I haven’t watched this video
Haven’t got time right now, just wanted to comment on my immediate thoughts.
So time travel may be possible? will mankind play with its timeline like a child with a gun? are we one day going to see goverments trying to get elected based on promises to remove/change certain events from history, “the remove hitler party” or the “medicine for our ancestors campaign” or would time travel to the past be strictly policed.
Perhaps in the future time travel to the past will be possible and we will send our historians into space, then let them travel back to specific periods of time, to observe historical events and gather accurate data passively from orbit.
Could that be an explaination for UFO’s? not alien tech, but simply tech from a future age of the planet.
probably not.
You can’t go back in time. Otherwise we’d have done it already!
Seriously, if you could go back in time, any impact you’d have on the world would just impossible. That didn’t happen a that time, in that place! It’d have to be in some sort of parallel universe (which means you’re not traveling in time, you’re creating another universe).
This seems right, but any thoughts?
If that were so we obviously would change history and stopped all wars and genocide therfore by now if that had occured we would now have a very big world food shortage.horrible things happen. That’s life (and death)
Morgan Freeman could read out the manual for a vacuum cleaner and it would sound interesting.
This show is pretty good, but fairly basic really. Pop science. They always repeat themselves and make…. each… point… very… very…. slowly.
Still, thanks for an interesting link and an entertaining 45 mins.
I am no genius in this subjet, but surely it doesnt all make sense. However, if time travel was at all possible and that we were able to change the past then surely sometime in the time line we would have already achieved this goal. assuming that time travel was successful to tha past then surely our past would have already have been changed and making no difference to the present. There has been no discovery of this in the past, of people travelling back in time to change events. With no time travel in the past then how could you assume there will be in the future. That is if no-one makes up a silly rule of not travel back in time before the machine was built, to insure safety. But as i said am no genius in this subject, just a quick thought.
You have to start with the fact that there is no time, it doesn’t really exist. It is only our perception of linear , physical changes. The closest we could ever come to traveling back in “time” would be the ability to accelerate past the speed of light and catching up to the images in the light waves that are moving away from their points of origin. Fun to think about, but only science fiction IMHO.

I do like Morgan Freeman he is very easy to listen to.
Ok, I get it, I understand the theory. But can someone help me out with this:
Freeman says that in space someone could travel for 10 years, but on earth that would equate to 1000 years. Although time is moving at different speeds, wouldn’t the body still age at the same rate thus the practice of the theory is pointless??
Please help!?!?!
This show just gets on my nerves.
“With no time travel in the past then how could you assume there will be in the future. That is if no-one makes up a silly rule of not travel back in time before the machine was built, to insure safety.”
That may be a law of nature, not a silly rule mankind would make up (there will always be people breaking those rules anyway). If entanglement is the way to go, a time machine wouldn’t be a vehicle but it would be a device that sends and receives information. In order to send information to the past there would need to be a time machine capable of receiving the information, meaning you cannot go back to before the time machine was built.
I’ve always thought that if it is possible to travel back in time, then doing so has to split the time line in two. So, the time traveler doesn’t affect his own time but rather a new time line. This would both explain why we haven’t run into any time travelers yet and prevent the grandfather paradox from occurring.
I just think that, even if it was at all possible, once you start messing about with time etc, you’re asking for trouble.

Waterbottle – that is my reasoning too. Well put.
Scott- DMT has given me many great experiences, including what seemed like time travel, but that is only from my perspective. The brain is a complex organ that creates an illusion of perception. It is not real time travel, at least not IMHO.
I could be wrong.
But I don’t think so.
ps no more psychedelics for me, got to be a responsible adult type person…
Long ago, I read a short sci-fi story which pointed out the catch to time travel: The space- time exchange rate is “c”, so a single second of time travel would equate to three-quarters of the way to the moon, and you would never have the time or energy to get any significant way into the past or future.
Here’s one for the stoners. Maybe the UFO’s that have been reported over the years are actually time machines and the inhabitants are actually us coming back to tell everyone to chill out because, “look at what we’ve evolved into”!!!
I have always believed that some day they could travel in time, according to quantum physics paradox would not exist because it would create another timeline, another parallel universe almost identical. It would be something like a tree with infinite branches. And this would explain why we have never … matched time travelers, and that if there are infinite worlds is infinitely branching difficult match any traveler, but not impossible.
Your amatuers they always knew tim travel was possible
