please help?easy qestion.?

Question

first i know light have no mass or weight.and i read that when a light goes in black hole it dont come for gravity so i knewed that a light ray have no mass or weight and if something dont have mass or weight it dont have any effect in gravity so light dont have a gravity effect because it is a power so my question is why all the other says when the light goes in black hole it gets sucked or traped by its gravity power.but why.it shouldent be happening am i right?
and what is a blackhole and a wormhole?(please say it in easy english cause iam only 14)
and do u think that if a planet have oxyzen and water can there be a life?
what is more faster than light?
well we know oxyzen is needed for fire to be burn do u think there is oxyzen in sun if no how can it be burning?
if you like my questions you can give me a star.
and take care.

Answer 1

ask your sir

Answer 2

Light has energy, and energy has mass, and anything with mass has weight when near another massive object and especially near a black hole.

A black hole is exactly what you say; a mass so very concentrated that light cannot escape from its gravitational pull. According to some the theories, wormholes connect distant regions of space and time, but no one has proved that wormholes really exist.

No one knows how easy it is for life to get going. So no one knows if other planets with water would have life on them. But all the oxygen gas on earth has been made by living things (the action of plants) and if we could detect lots of oxygen on another planet we could be very sure that it was evidence of life.

The Sun is not burning chemically. Its energy comes from nuclear fusion which is turning hydrogen into helium.

Nothing can travel faster than the speed that light travels in empty space.

Excellent questions. I was very surprised to read that you are only 14. Keep up the good work of thinking about all these things, but next time please run a spell check before you post.
