how fast is the speed of light in kilometers per second?
How fast does light travel per second in meters?
The speed of light is sometimes referred to as the “cosmic speed limit”. Light travels in a vacuum at 186,282.4 miles per second or 299,792,458 meters/second. For simplicity, it is often said that these numbers are 186,000 miles per second, and 3.00 x 10^8 meters per second. Nov 2, 2009

How fast is the speed of light in seconds?
Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the continental U.S. once in 4 hours.

What is the second fastest thing after light?
The second and third fastest things in the universe are matter going at 99% of the speed of light, or like 99.9 or 99.99 and on, percent of the speed of light. However the number one fastest thing in the universe belongs to 2 things, photons, which carry light, and gravitons, which carry gravity.

Why is Lightspeed the limit?
Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

Why is the speed of light 300000 km s?
Light moves at the universal constant through three dimensional space because it doesn't move through time (the fourth dimension) at all. All particles move through the four dimensions of spacetime at the same velocity which is why it's called the universal constant velocity. Feb 13, 2016
