comment “How the Universe Works”: is it scientifically accurate?
What concept specifically are you concerned about? I don't think you can declare an entire series of material covering hundreds of topics broadly either scientifically sound or bunk. There's no useful information to be had from that. What are you asking about specifically?

comment What is the minimum mass required so that objects become spherical due to its own gravity?
You would have to define "objects." Icy bodies start to become round under their own gravity at a certain mass. Rocky planets will take more. Liquids would form a sphere with miniscule mass as I assume gas proto-planets would be round as soon as they have enough gravity to be considered an "object."

comment What is that void that the universe is growing into?
If someone is up to speed on the current state of "we really don't know" -ness, please feel free to add that as an answer.

comment If NASA is going to capture an asteroid with a spacecraft, wouldn't a UFO be able to manuever a celestial body?
This question appears to be off-topic because it it not about the subject of astronomy as defined in the Help Center

comment Class presentation on the Sun, ideas?
@Sawarnik chat.stackexchange.com/rooms/815/the-observatory. It's a bit quiet because this is still a new site.

revised Why is the speed of light 299,792,458 meters/sec?
Clarified much more interesting question than at first apparent.

comment Class presentation on the Sun, ideas?
Another way to say this is that this site is designed to create a work of reference to answer questions about the field of astronomy. We'd love to help, but a more appropriate place for your discussion is perhaps in our chat room, or even better, a threaded discussion forum that supports more generalized discussion. And, yes... good luck!
