00:01
So we know light is traveling three times 10 to the eighth meters per second.
00:05
We are seeing the sun as it was eight minutes ago, and eight minutes is essentially 480 seconds.
00:12
And so we're seeing the distance of 1 .44 times 10 to the 11th meters, which is actually approximately the distance between earth and the sun.
00:58
And this makes sense because it takes about eight minutes for light to travel from the sun.
01:03
Sun to the earth and so this makes sense.
01:06
However, your hand is extremely close to you relative to the speed of light.
01:12
So here we can say that we see our hand as present because light travel.
01:36
So we know light is traveling three times 10 to the eighth meters per second.
01:42
We are seeing the sun as it was eight minutes ago and eight minutes is essentially 480 seconds and so we're seeing the distance of 1 .44 times 10 to the 11th meters which is actually approximately but the distance between earth pulls from our hand to our eye in nanoseconds it's really really small again, if you want it to be technical, yes, you do see your hand in the past.
02:23
However, it's only on the order of nanoseconds, so it is essentially in the present.
02:29
It's, of course, not going to make any difference between and the sun...
