Okay, lemme try this again, I obviously did not explain myself well enough. I got this idea from a discussion elsewhere about rotating a disc so fast that the outer edge exceeds lightspeed. Someone responded that the atoms would break apart at close-to-light speeds, and the experiment would fail. So I came up with this idea which is independent of any object which might break. But I think it will be easier if I talk about light beams instead of shadows.
The radius of Earth’s orbit around the sun is about 150,000,00 km. That makes a circumference of about 950,000,000 km. I am near the sun, and I have a powerful laser with me, shining a powerful light. I rotate this laser at the very lazy speed of one revolution per minute. It will shine on one part of the earth, and then another part of the earth, and another, and then it will shine into various parts of empty space until it completes one revolution along earth’s orbit.
My point is that the shiny dot which it is placing on the earth’s surface will move across that surface at the speed of 950,000,000 km (the circumference of earth’s orbit) per minute (the laser is spinning at 1 rpm, remember?). This is equivalent to 16,000,000 km per second, which is FIFTY TIMES faster than the speed of light (300,000 km/sec).
Example: The moon is about 385,000 km from the earth. Therefore, it will take about 1/40 of a second for this spot of light to get from the earth to the moon, but it takes about 1.3 seconds for light from the earth to go to the moon directly.
No physical laws are broken here. All the photons leave our laser at the same 300,000 kps. The only thing is that it took 1/40 of a second for the laser to rotate from facing the earth, until it was facing the moon. A shadow would do the same thing, if an object would move past the sun at similar speeds.
But I cannot think of any practical usefulness of this idea. Can anyone else?
