The faster the Earth spins, the shorter our days would become. With a 1 mph speed increase, the day would only get about a minute and a half shorter andour internal body clocks, which stick to a pretty strict 24-hour schedule, probably wouldn’t notice. ...
nothing in the universe can travel faster than light. The theory states that as matter approaches the speed of light, the matter's mass becomes infinite. That means the speed of light functions as a speed limit for the wholeuniverse.

Potter's feat might remind you of tightrope walking, but there are some important differences. Tightrope walkers usually carry a long pole to help maintain their balance and perform on a heavy steel cable pulled tight so that it doesn't move very much. Highliners, on the other hand, balanc...

(which is what they're called while in space) moves at 133,200 mph (214,365 kph) when it hitsEarth's atmosphere(and then it is called a meteor). Most of the Perseids are tiny, about the size of a sand grain. Almost none of the fragments hit the ground, but if one does, it'...

The distance from the sun to the earth is 1.496×108 km. How long does it take light to travel from the sun to the earth? Speed of Light: The speed of light is the universal speed limit. Nothing can move faster than this and no...
Rockets move upward by firing hot exhaust gas downward, rather like jet planes—or blown-up balloons from which you let the (cold) air escape. This is an example of what's often called "action and reaction" (another name for Newton's third law of motion): the hot exhaust gas firing ...
Photo: Many people's ideas of electric cars are still based on vehicles like the famous experimental GM Sunraycer, which looks amazingly futuristic—but is now over 30 years old. The whole of the back section (everything to the right of the white cockpit) is covered in thousands of ...
