I have tried to research this through search engines but have come up with very little answers. This question is why I've registered with this forum. I am curious about the behavior of low level infrared and laser beams similar to laser pointer pens and remote controls. Specifically what happens when these low level beams intersect one another at exact or similar wavelengths. Do they ricochet do they pass through do they alter one another? etc. etc. And whatever the differentials may be in their intersection is there a property change when one of the intersecting beams is turned off? Can that be seen as a variable difference in the patterns entirety? Any thoughts or ideas are appreciated and welcomed. Thank you for your time and interest.

After reading the replies to this thread I came up with one distinct reaction. "Position in space relative to what?" I think there is more to be found about astrophysics as well as the concept and theory of time to really compact it into a state of physical or theoretical measurement. Perhaps as we move in time we are always in the same space in the now. So would not any method of time travel factor in the movement and transition of photo sensitivity to that now we travel towards and thus move us into that space respectively of the chain of events that brought us from that point in time?
