@mcguirefinds: Did you know? Light travels in a vacuum at an incredible speed of about 300,000 kilometers per second. This is also considered the cosmic speed limit. The speed of light is a fundamental constant of nature, the highest speed atwhichan/thing.in spacetime can travel. Even if we could travel at the speed of light, it would still take millions or billions of years to reach some places in the universe. The universe's vast distances are measured in light-years. One light year is the distance that light travels in one year in space, about 9 trillion kilometers. The nearest star to our solar system is 4.3 light-years away #space
