What more exciting possibility does physics raise than time travel? We all dreamed of an opportunity to visit the Triassic or repeat an exam in “ the DeLorean .” Of all the paradoxes that our interpretation of physical phenomena brings us, probably…
A recently discovered galaxy resembles a tomato that has been squished or perhaps the top of a cherry-flavored Ring Pop. Just a red blob, so hazy and without edges that I had to double-check that my contacts were in before I even looked. I say thes…
Is time travel possible? Well, we might find the answer in this amazing video. Professor Brian Cox, a Doctor Who admirer, makes a stunning experiment to prove the Physics and possibility of time travel. His conclusion: Time travel is possible, b…
The ability to travel through time, whether it is to fix a mistake in the past or gain insight into the future, has long been embraced by science fiction and debated by theoretical physicists. While the debate continues over whether travelling into…
Almost a century ago, Edwin Hubble’s discovery of red-shifting of light from galaxies in all directions from our own suggested that space itself was getting bigger. Combined with insights from a handful of proposed non-Euclidean geometries, Hubble’…
Science fiction requires its fans to suspend their disbelief, and there’s no greater ask in that department than when trying to enjoy a time travel story. Writers twist their plots into Gordian knots to explain how time travel could logically work …
The laws of Physics say that energy in a closed system is always conserved. Such as in our own Universe energy is conserved. It may be converted, concentrated and dissipated, but it’s never lost. James Prescott Joule built an apparatus wh…
Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains what we know about time travel so far. Following is a transcript of the video.
It turns out that black holes could, in fact, be a sort of tool for time travel. Some astronomers have suggested that space-time curves are found near the center of a black hole, but these do not break and rather continue in a region in the futu…
Time travel is nothing special. You’re time traveling right now into the future. Relativity theory shows higher gravity and higher speed can slow time down enough to allow you to potentially travel far into the future. But can you travel back in ti…

Alright Dr. Who, move over now. Scientists have built what could loosely be described, by all known scientific concepts, like a time machine. A new scientific experiment, whose results have been published in the journal Scientific Reports , …
