About 70% of the speed of light (186,000 mph).
In other news... what website do I go to and get signed up to be called a 'scientist'? Or is that a certificate I can order from Amazon?
Light travels at 186K miles per SECOND. So divide the 70% by 60, then by 60 again. It's traveling about 0.019% the speed of light, but still faster than my kids when they started driving. LOL
The speed of light in a vacuum is 186,282 miles per SECOND, not per hour.
150,000 mph is nowhere near the speed of light.
No. It is (2/3 of the speed of light)/60.
About a bit more than 1% of the speed of light, about 1/90 the speed of light.
You forgot to carry the 2. :)
1/5,163,600 of a light-year
So (assuming constant velocity) it would have taken approximately 21,887 years for an object traveling at 130,000 mph to reach Earth from Proxima Centauri (closest star at 4.24 light years).
Proxima doesn’t strike many as a likely candidate for life, so it would probably would have had to be sent sometime when the dinosaurs ruled the Earth.
“About 70% of the speed of light (186,000 mph).”
186,000 miles per second, 700 million mph.
The speed of light is 186,000 miles PER SECOND. So divide 70% by 3,600.
“ About 70% of the speed of light (186,000 mph).”
The speed of light is 186,000 miles per SECOND.
