Is there different types of light/particles of light? because all of these lights are different how it works, laser light, light from flash light, sun light. Why does flash light only illuminate only less area/more area depending on how much volts the battery is and a sun illuminates a whole...

I understand that rockets propel something because of, "Isaac Newton's third law of motion: Every action produces an equal and opposite reaction." (Kind of away from the original question, just curious) But, how does that action produce equal and opposite reaction. What is happening? or what is...

Imagine an apple and it's skin (The skin of the apple is the edge of Earth to space that i mean). For Earth what is the skin like an apple's skin? Is Earth's skin the Exosphere, thermosphere, mesopause, and/or stratosphere. How much gravity is on these layers of atmosphere of earth, Does the...

So at the edge of Earth to space, it's less gravity? And also, Space shuttle needs approx. 11 km/sec velocity at edge of Earth to space? If it doesn't have the approx. 11 km/sec velocity, would the space shuttle just stall and fall back to Earth or what happens?

Thank you all for the feed back :)

My understanding is that for space shuttle to escape Earth it needs to travel at a certain high velocity. So, what happens to the space shuttle if it doesn't reach the escape velocity at edge of Earth's atmosphere to space? The question I'm asking and the answer I'm seeking is something like...

I get questions and i hope you have the concise answers.
