I am not a physics student and have only a non-math, science channel understanding of physics but I do have curiosity.
Does light have gravity?
When stars convert matter to energy what happens to the gravity?
What approx. percentage of original big bang stuff {in the current standard model} is now matter and what part energy?
Do dark matter and dark energy question/theory take in to account the gravity of energy, if it exists?

Explain why the following statement is wrong:
‘The moon does not fall down as it moves around the earth because the centrifugal
force balances the force of gravitation and hence there is no net force to make it fall.’

I am travelling in a space vehicle at 0.999xC. I carry a missle that also flies at 0.999xC. As I fly past a space station with a velocity of zero relative to my frame, I fire the missile. What will I see the missile doing? What will an observer in the space station see the missile and my ship doing? Thank you very much.
