Are anti-particles particles with a negative time value and that is why they are "destroyed" when they interact with normal matter with a positive time value?
I am not a physicist, but a physician. I heard one of my patients say this and thought it was too interesting a concept not to get further opinions on it, so better to ask reddit.

how can i be watching a movie from the 1970's in blu-ray?
I was watching Alien [1979] the other day on Blu-ray when I realized, how can this be better than HD quality? Wasn't it filmed before 1979 when HD cameras didn't exist? It still looked good, but is it worth buying over a DVD version? I feel like there had to be a quality cap at the time of filming.

why are 3d printed gun such a big deal?
3D printed guns have been all over the news in the last year or so, but I don't really get it. I understand that now anyone can print their own gun at home, but just molding a gun and its parts can't be a lot harder, right?

In mid-1863, Vicksburg fell, and the Confederacy was officially split by the Union controlled Mississippi. How did this change the levels of support, and perception of the effort, within the regions of the Trans-Mississippi still under Confederate control?
To be sure, I figure that Vicksburg falling was more symbolic than *literal* as it wouldn't be impossible to slip through, but I would expect that that symbolic loss, with the Union now able to patrol the entire river unmolested by shore batteries or enemy ships, would be a pretty devastating blow not just to morale ge...
