If we are looking at hours, that translates to For a little context, if you were traveling at the speed of light, you would be able to whip about the Earth 7. Since the universe is such a vast place, if we measured distances in miles or kilometers, we would be working with some amazingly huge s. As such, we measure cosmic distances according to how fast light can travel in a year. If you are wondering, there are just about 31,, seconds in a year, and if you multiply this by , the distance that light travels each second , you get 5. In short, on Earth, we talk about things in relation to feet or meters, but in the cosmos, we talk about things in relation to light.
For example, the Milky Way galaxy is some , light-years across, and our closest galactic neighbor, Andromeda, is some 2. In other words, it takes light 2. Remember that the next time that you see a Hubble image that shows a host of galaxies dancing across the cosmos—what you are looking at is amazingly far away. The time that it takes us to travel one light-year is unsurprisingly considerably longer than a year. In fact, it takes between six months and a year just to reach Mars, which is only And it took New Horizons nearly a decade to make its way from Earth to Pluto, which is just around the corner, 4.
Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37, years to go one light-year. The worst thing? The closest star, Proxima Centauri, is more than four light-years away. Care about supporting clean energy adoption? Find out how much money and planet! By ing up through this link , Futurism.
