Last week Elon Musk said in one of his 100-plus daily tweets that “This is just a very basic first step. Earth and Mars will ...

Here’s how it works. The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant ...

The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length ...

In special relativity, the speed of light is the ultimate speed limit to the universe. Every single moving object in the universe is constrained by that fundamental limit. This isn’t something like ...

A series of new animations by a NASA scientist show just how zippy - and also torturously slow - the speed of light can be. Light-speed is the fastest that any material object can travel through ...

In Newtonian physics, gravity was thought to be instantaneous. But in Albert Einstein’s general theory of relativity, the speed of light, c, is the fastest possible speed for any interaction that ...

"We speed up the velocity of electrons to 80% the speed of light," Wang said. That's an acceleration of zero to more than 500 million miles per hour—over the span of just two inches inside the ...

The transcript below has been edited for brevity and clarity. FTAV: In Trading at the Speed of Light you describe high-frequency trading (HFT) as both Einsteinian and mundane. What do you mean?

Y Combinator backed Codebuff allows developers to code with AI directly from their command line interface (CLI).
