>>10003700No, he's right. Light travels fast enough to circle the earth about 7.5 times a second. Don't straw man the dude, that's /pol/tier posting. And that was a clear and apparent straw man. As far as the other portion goes, our data is limited by the machine's ability to receive the information, process the information and then that information in to data. That delay is why he thinks the speed of light is unverified as there are machine variables that could alter it. He would be correct, if we were doing the expirament 2 feet away from each other. For our purposes, light would be instant of the distance is only 2 feet. As the time it took for light to travel to feet is magnitudes shorter than the amount of time it takes for our eyes to read that information, pick up the data, send it to our brain and then have our brain interpret the results. Same concept. Except he's stupid, we do have mirrors on the moon, and have ran these tests from those mirrors. Seeing how it takes roughly 2.6 seconds for light to reach the moon, then make it's way back. We can reasonably assume that the machine taking these readings is not taking 2.6 seconds to interpret the results.
