As a Ph.D. student in Astrophysics, I appreciate your effort in explaining this extraordinary science topic to the general audience in simple language. Great job !!... You should continue to put more such science videos so that at least people should see the hard work of the scientists and know the cosmos. Most importantly, they should realize that we are the stardust, nothing more. So there is no need to spread bad things; just enjoy the beautiful nature on Earth, the one and only habitable place in the known universe.
