Good. Now that you realize the distance. Think about how fast any of our spacecraft travel in relation to the speed of light.Umm yeah i do. 1 Light year is how far light travels in one year, and light speed is approx. 186,000 miles per second. do the math and light travels approx.
5,865,696,000,000 miles in one year soooo in 20 years it is....
117,313,920,000,000 miles. *whew* so yeah it's a lot. i'm saying we could possibly make contact with radio waves or somthing since it goes speed of light (right?)
