Space exploration beyond Mars is one of the greatest challenges humanity faces, and the key to success lies in solving the time-distance problem that holds us back from exploring the outer reaches of ...

The Alcubierre Warp Drive is one of the most fascinating theoretical concepts in modern physics, proposing a method to achieve faster-than-light travel without violating Einstein’s relativity. This ...

From Christopher Nolan's Interstellar to the iconic Back to the Future series, here are the best time travel movies.

With those enormous distances in mind, consider Cristina’s question: How can light travel across the universe and not slowly lose energy? Actually, some light does lose energy. This happens when it ...

Even with the highest speeds we have been able to achieve so far, interstellar travel would be extremely time-consuming, which makes this type of travel a great technical and logistical challenge. To ...

New propulsion method could achieve interstellar travel within a lifeti Relativistic electron beams could reach 10% of light speed Cost-effective alternative to laser-powered sails for space travel ...

That’s when you encounter your first problem ... a consultant on the science of Interstellar, quantum mechanics could hypothetically explain a way to time travel via wormhole.

It could be that our future descendants discover an alternative way to stabilize wormholes and allow for interstellar travel ... but that is an engineering problem, not a physics one.

As Larrouturou told Universe Today via email: “Interstellar travel is primarily a problem of propulsion and – even more acute – power. The power required to send a Voyager-class probe to ...
