The Breakthrough Starshot project plans to send small spacecraft to Proxima Centauri, and it could use the light of Alpha Centauri it get there.
If you’re the captain of a starship exploring the galaxy, how do you find your way home?
The Death Star appears huge in a new poster for Rogue One. Could a death star actually appear so large in real life?
When it comes to time travel, everyone kills Hitler on their first trip.
As far as time travel is concerned, making the journey from 1985 to 2015 is easy.
In The Martian, journeys to Mars are made possible through a large spacecraft known as the Hermes. While the Hermes is a work of fiction, it’s based in well established science.
For Interstellar, scientists created an accurate view of a black hole. How much the science reached the screen?
A cosmic string is a very long (possibly as long as the diameter of the visible universe), very thin (less than the width of a proton) high-density object formed during the early moments of the big bang. You can see a rendering of such a string in the image above. There is a reason why it appears next to the starship Enterprise. Both of them are science fiction.
One of the big questions about the universe is whether there is intelligent life “out there”. We know that life evolved here on Earth, so it seems possible that similar life could evolve on other worlds. Whether they would survive and evolve what we would consider intelligence is another matter. There have been some estimates made on just how likely this might be, such as through the Drake equation. There is a lot about these estimations that are purely speculative, but we do know that Earth-like planets (at least in terms of size and temperature) are likely very common. We also know the type of chemical elements life on Earth relies upon are common, and that life appeared on Earth relativity early in its history.
