Is Time Travel Possible?
In Summary: Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
Is Time Travel Possible?
Time traveling to the near future is easy: you're doing it right now at a rate of one second per second, and physicists say that rate can change. According to Einstein's special theory of ...
Can we time travel? A theoretical physicist provides some answers
The simplest answer is that time travel cannot be possible because if it was, we would already be doing it. One can argue that it is forbidden by the laws of physics, like the second law of ...
Will time travel ever be possible? Science behind curving space-time
According to NASA, time travel is possible, just not in the way you might expect. Albert Einstein's theory of relativity says time and motion are relative to each other, and nothing can go ...
Paradox-Free Time Travel Is Theoretically Possible, Researchers Say
Time Travel Theoretically Possible Without Leading To Paradoxes, ... in part because according to Einstein's theory of general relativity, "closed timelike curves" are possible, theoretically ...
Time travel
The theory, which suggests that wormholes could work as viable space-time shortcuts, was described by physicist Pascal Koiran. ... Time travel is possible in the Star Trek universe. (Image credit ...
Is time travel even possible? An astrophysicist explains the science
Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.
Time Travel and Modern Physics
The simplest possible example is the Newtonian theory of perfectly elastic collisions among equally massive particles in one spatial dimension. The space-time is two-dimensional, so we can represent it initially as the Euclidean plane, and the dynamics is completely specified by two conditions. ... Similarly, even if all of our consistency ...
Can time travel survive a theory of everything?
Yet time travel does not necessarily violate the laws of physics. In Einstein's theory of gravity — general relativity — space and time are merged as spacetime, which allows for the ...
Is time travel even possible? An astrophysicist explains the science
Time isn't the same everywhere. Some scientists are exploring other ideas that could theoretically allow time travel. One concept involves wormholes, or hypothetical tunnels in space that could create shortcuts for journeys across the universe.If someone could build a wormhole and then figure out a way to move one end at close to the speed of light - like the hypothetical spaceship ...
Is Time Travel Possible?
Whether time travel is possible is among the most intriguing questions in all of science. Neil deGrasse Tyson explains how time travel into the future is pos...
Is time travel possible? Here's what science has to say about it
Does Einstein's theory tell us that time travel is possible? This question has been studied intensively since the 1990s, with early work by Igor Novikov, Kip Thorne and others highlighting the ...
According to current physical theory, is it possible for a human being
Much work has been done by theoretical physicists in the past decade to try to determine whether, in a universe that is initially without time travel, one can build a time machine--in other words ...
Time Travel
To enter the region where time travel might be possible, one would have to cross the Cauchy horizon, the hourglass-shaped (for two crossing cosmic strings) boundary of the singularity in which the laws of physics are unknown. ... Certain aspects of quantum theory are relevant to time travel, in particular the field of quantum gravity. The ...

Time Travel. First published Thu Nov 14, 2013; substantive revision Fri Mar 22, 2024. There is an extensive literature on time travel in both philosophy and physics. Part of the great interest of the topic stems from the fact that reasons have been given both for thinking that time travel is physically possible—and for thinking that it is ...
Time travel could be possible, but only with parallel timelines
Of course, even if we manage to find such a theory, this would not be sufficient to prove that time travel is possible, but it would at least mean that time travel is not ruled out by consistency ...

How a rotating universe makes time travel possible
Gödel was curious as to whether relativity could allow time travel into the past. Einstein's theory purported to be an ultimate framework for the nature of space and time, and as far as we know ...
The Scientific Possibilities of Time Travel
Time and Relativity . Though referenced in H.G. Wells' The Time Machine (1895), the actual science of time travel didn't come into being until well into the twentieth century, as a side-effect of Albert Einstein's theory of general relativity (developed in 1915). Relativity describes the physical fabric of the universe in terms of a 4-dimensional spacetime, which includes three spatial ...
