When it comes to time travel, everyone kills Hitler on their first trip.
Back To The Future Is Easy – It’s Back To The Past That’s Hard
As far as time travel is concerned, making the journey from 1985 to 2015 is easy.
The Science Behind ‘The Martian’ Hermes Spacecraft
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.
Could We Ever Build A Time Machine?
When Einstein developed his gravitational theory of general relativity, some physicists began to wonder if time travel might actually be possible.
How to Travel Faster Than Light Without Really Trying
It turns out there are several ways things can travel faster than light, depending on what you mean by a “thing,” “faster-than-light,” and “travel”.
No Makeup Selfie
For Interstellar, scientists created an accurate view of a black hole. How much the science reached the screen?
Wishing Doesn’t Make It So
When our science fiction dreams run into the limitations of science itself, some barriers simply can’t be broken.
Stringing You Along
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.
Alien Glow
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.
