ya know, I've seen this kind of theory before and it always baffles me. Pretty sure even with today's tech getting peeps to Mars is super tough. The 60s? haha, nope. Plus, the moon's pretty unique with its grey ground and lack of atmosphere. The red planet is, well, red.

I'm not a scientist, but this makes me think... Stars give off a mind-blowing amount of light, so if light had mass, wouldn't that potentially cause stars to lose mass super quickly? Almost like a constant mass ejection. That'd change the whole stellar lifecycle.
