    Inside neutron stars we can find the weirdest and most dangerous substance in the universe: Strange matter. What is strange matter, how dangerous is it and what can it tell us about the origin of the universe?

                    If strange matter could convert any other matter into itself, wouldn't it convert completely the neutron star that contains it first? And we should have found many strange stars already, considering strangelets could convert many other stars as well.

                      So why can't we just follow the splatter of nutron star collisions so see if there is any statistical increase in nutron stars there?

                                Before watching the video, I thought that it being called Strange Matter had to do with quarks (Strange and Charm quarks, to be precise) Im only 2 minutes in, so I'm just gonna.. uhh.. keep watching.

                                      When you said that it takes you 1200 hours to make a video. I did the math and if you work without sleeping it would take you 50 days. But with sleep it would take you 100 days if you work 12 hours a day. So I think you lied. No offense.

It requires at least two full passes: one to take in the wealth of new knowledge, and one to take in the absolutely adorable animations. Personally, I recommend spending two passes for each of the two.
