The animation above does a great job showing both how fast and slow light speed really is. The speed of light is theoretically the fastest speed you can travel in the universe. At 299,792,458 m/s (186,282 miles per second) it is really, really fast. However, given how vast space is, it’s also really, really slow.
The 4 examples in the video show this really well:
- Light can orbit the earth 7.5 times per second – (Really, really fast)
- Light can reach the surface of the moon from the earth (or vice versa) in just 1.255 seconds – (Still pretty fast)
- Light takes at least 3 minutes and 2 seconds to go from the Earth to Mars (or vice versa) at the closest approach (54.6 million KM; 33.9 million miles) – (Not so fast)
- Light from the Sun takes 8 minutes and 17 seconds to reach Earth (1.0 AU: 149.6 million KM; 93 million miles) – (Sort of slow)
To put that even more perspective, the closest start systems to us is Alpha Centauri which is 4.37 light-years away. This means at the time of writing they still haven’t heard the news about Brexit or Trump.
