Time travel is impossible. Here's why:


Moving object from one point in time to another would be problematic.

The atoms in an object have existed since the beginning of time.

You can't create or destroy them so if you move one through time, wouldn't that same atom have to move in every timeframe in eternity? The atom from last year would shift in time the same degree cause it's the same atom and it's connected to itself through time.

That's great for a chunk of gold or something but for a person that presents a huge issue.

You're made up of different atoms now than you were ten years ago. Essentially you'd rip your past and future selves apart on an atomic level.

Wrong, but it is too dangerous.
That is why President Trump banned it in 2019.
Too bad because we could have used it to stop the Zombie Apocolypse in 2024

There are theories on how time travel would be possible, but to go to the past would involve doing things that could never happen.

However, sending light particles into the past has already been accomplished and raises the possiblity of sending messages back in time.

Obviously time travel is impossible as if it ever were there would be millions of people winning lotteries everyday, to the degree that lotteries would never exist to begin with.

I think you misunderstood. The article discusses a scientific observation of a pulse of light emerging from gas before it even entered. To simulate this observation, scientists created a chamber to further analyse/test their findings and discovered that the pulse of light was theoretically moving at 300 times the speed of light. The above user was simply claiming that if these observations where solidified and this field of research progressed further, we could at one point reach a point where we could send simple messages back in time.

To sum up the observation in the article: Einstein's research theorizes that nothing physical in the universe can be faster than the speed of light, and doing so would mean to be traveling back in time. Since this is assuming that light is the upper barrier of speed in this universe, to exceed it would mean you would have to be traveling back in time to do so.

This article is written about low level observations and only speculating upon possibilities. Moreover, the article was written in 2000, so I imagine it has not gained much traction in development since we would of heard more about it. You are correct in that actual time travel does not exist, however the above use was not claiming that it did.

Finally, it is in my belief that if at any point in time we do invent a form of time travel, it won't be to the past based upon Einsteins theories. If there is any potential for time travel, it will be to the future due to research in the theory of relativity and time space being more of a curved surface than a linear line. With the recent discoveries of black holes further providing proof into Einstein's theories, who knows where the future will take us in this field of research!(no pun intended)

Time travel is theoretically possible -- or, at least, not theoretically impossible -- according to General Relativity and Quantum Mechanics as we know them.

Excellent post. I'm glad someone used logic to show that a fictional movie is wrong about time travel. Now can you do the same sound in space for Star Wars?

In my opinion, time travel would be even more problematic if you take global movement into account. If you travel back or forward in time, you wouldn't arrive in the same location. The earth is constantly moving. Any time travel at all and you would arrive at your time destination floating in space. The only way it could work would be if you opened a temporal wormhole.

Interesting to think that there are rules regarding atoms and introducing new ones would some how throw out of balance the atoms at play in the universe.

Time travel is not only possible but has already been mastered. First thing you have to do is disregard any known equations and theories that we have been taught. They're wrong. DARPA has been running Project Pegasus for decades.

Actually "time-travel" is possible, because each of us is doing it right now. We are traveling into the future at approximately the same rates.

It appears that only travel to a future time is possible, and in theory a person could travel to a time 10 or 50 or 100 or more years into the future, but you would have to be traveling at very near the speed of light, or be very near a massive gravity like a black hole. Then for you time would slow to only a fraction of what everyone else back home is experiencing. When you'd return you would be going back to a far future time.

It will likely always remain theoretical because there is no practical way to do either of those, travel near the speed of light or park yourself near a massive black hole. While it is possible that some way could be discovered in the future, it is not likely and certainly not in our lifetimes.

As far as traveling to the past, can't do it. The past is gone forever, remember it if you will but trying to travel back to it will kill you. Unless you have a DeLorean fitted with a flux capacitor and a way to generate 1.21 Gigawatts of electricity!

The Tenth Doctor: "People assume that time is a strict progression of cause to effect, but actually, from a nonlinear, non-subjective viewpoint, it's more like a big ball of wibbly-wobbly, timey-wimey... stuff."
