There's no law of physics that outright forbids interstellar travel. But that doesn't necessarily make it easy, and it certainly doesn't mean we'll achieve it in our lifetimes, let alone this century.

Study: 1960 ramjet design for interstellar travel—a sci-fi staple—is unfeasible "It is very unlikely that even Kardashev civilizations of type II might build magnetic ramjets." ...

Interstellar Space Travel: 7 Futuristic Spacecraft to Explore the Cosmos Paul M. Sutter is an astrophysicist at The Ohio State University , host of Ask a Spaceman and Space Radio , and author of ...

Interstellar travel could be possible, scientists say, but not in the way you might think. For decades, science fiction stories have proposed the idea of traveling outside of our known galaxy.

Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To send a spacecraft, weighing roughly 1,000 kilograms, to a neighboring ...

Here are some potential ways we Earthlings could achieve interstellar travel, ranked from least to most likely. Skip to content Introducing the all-new Astronomy.com Forum!

Until we work out how to warp time and space, interstellar travel is going to be a very slow boat to the future. It might even be better to think of that travel period as the end itself, rather ...

In the 2014 film Interstellar, humanity takes advantage of a wormhole near Saturn to travel to different galaxies in minutes while searching for a new, habitable planet.Similarly, a network of ...

Interstellar travel is one of the most frustrating topics in all of astrophysics. Despite hundreds of articles, movies and TV shows devoted to the subject, in most professional astronomical ...

Interstellar travel isn't actually all that farfetched. At least if you're patient. "It's a little out there, but it's really not as crazy as most people think initially," says Jeff Coughlin, ...
