Gravity, the force that keeps things from flying off our planet, is also the force that prevents light from leaving a black hole. A black hole is presumed to consist of matter so densely compacted that its gravitational force is sufficient to hold back even the highest energy particles known.
almost none the vast majority of visible light passes through the atmosphere.

The ozone is important for life on this planet because it forms the protective bubble that keeps our atmosphere in and keeps it from escaping into space. It also acts as a sort of shield and blocks harmful rays from the sun.
The layer of Earth's atmosphere which keeps us safe is ozone layer. Stratosphere is where it lies.
The speed of light is constant in a given medium.

Meteor is the term used to describe the streak of light (also called a shooting star) that passes through the atmosphere. The light is caused when a meteroid hits the atmosphere and burns up.
Yes. Light is measured in photons and it is quite evident that the atmosphere is transparent to light.
because that way it keeps us from the sun and light
almost none the vast majority of visible light passes through the atmosphere.
almost none the vast majority of visible light passes through the atmosphere.
As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or gas molecules
Meteor.
Yes
The mass of the Earth provides insufficient gravitational attraction to prevent these very light gases from escaping into space.
