What I Learned Today

Along with the entire scientific community, I learned (as Einstein suspected) that the speed of gravity is the same as the speed of light (i.e., 186,000 miles per second or 299,792,458 meters per second).

So, if the Sun suddenly disappeared, Earth would shoot off into space at precisely the same time the lights went out (about 8.3 minutes after the Sun went kablooey).

    Uhhhhhh I hate to burst your bubble but the sun is over 91 million miles away from earth at it’s closest point, over 94 million miles at it’s furthest.

    Light, and gravity, take around 8 minutes and 20 seconds to reach earth.

    Yeah - typo. My bad. I edited the post to read “minutes” instead of “seconds”.

    It was late…
