at the toparticle said:time travel is impossible.
OK. But I don't see anything within the article relevant to that statement. Time travel is just as impossible as it's always been--nothing new has been revealed. It's just confirming what we've understood all along.flyingpig said:because it says at the top
hubewa said:Well, technically, by the definition of the phrase, we are all "time travellers".
However, it is possible to travel into the future. If you speed up so that you approach the speed of light, the theory of relativity states that your time slows down relative to people on Earth. That means that, when you return to Earth, you will be in the "future".
However, this is irreversable. Once you have traveled to the future, you cannot travel back, as this article concludes.
If you read a little bit further into the article, you may have realized that it was referring to traveling back to time, so the statement "time travel is impossible" is a bit misleading.
Loren Booda said:The universe beyond our event horizon moves general relativistically (by "inflation") faster than the speed of light. Could there be related, local effects (like the potential for time travel) of the inflationary Higgs mechanism?
Currently, there is no scientific evidence or technology that suggests time travel is possible.
According to the theories of relativity, time travel may have been possible in the past, but current advancements in science and technology have shown that it is not feasible.
While it is currently not possible with our current understanding and technology, it is always a possibility that future advancements may make time travel a reality.
There are many theoretical consequences of time travel, including the possibility of changing the course of history, creating paradoxes, and altering the fabric of time itself.
There have been numerous studies and experiments conducted to explore the concept of time travel, but so far, none have provided conclusive evidence that it is possible.
