Why the Speed of Light is Actually Horribly Slow

slash real-life floor lights is about the fastest thing that you can possibly imagine think about how fast it seems when you turn on a light switch in your room and you see it instantly fill up with lights or when you shine a flashlight on something and the light immediately appears on whatever you’re shining it acts it feels instant because of our scale light moves so quickly that it might as well be but when you move out beyond our scale light get slower and slower to the point where it quickly seems to more resemble a snail rather than you know light speed here’s what I mean light on earth seems really really fast because earth is small light travels at a speed of 299,792,458 meters per second when in a vacuum which is fast enough to completely orbit the entire earth more than seven times in a single seconds which looks like this while it’s happening when you flip on a light inside of your room the light probably moves fast enough to reach across the entire room in just one 500 thousandth of a second which tamir human eyes basically feels instant this is why instant communication on the internet between any two people on the earth’s surface is possible because earth is a small enough place to where light speed basically does mean the same thing as instants but that all changes drastically when we zoom out just a little far away from the earth and get out into the rest of the universe far from being instantaneous it takes light 1.25 five seconds to cover the distance between Earth in the moon which has all kinds of weird implications when the Apollo astronauts were there there was a lag in communication between them and Mission Control back on earth because a message from Mission Control would take 1.25 five seconds to arrive and then the astronauts message will take 1.25 five more seconds to come back for a total
