Let's say for example someone was in a car accident or whatever, and the car bursted into flames. Why would this happen? How would this happen? Too much heat? In movies you see cars exploding but I think everyone knows they tend to bend the truth a little in movies to make things more interesting but is this actually possible? If so why would it explode? I would assume it has something to do with the oil, gasoline and/or heat. Can someone who knows cars go into specific detail about the parts of the cars that would actually make these things happen?

We believe in scientific theory that since light have finite speed, the stars that we see are of the past.

Imagine a star that emits light radiation of different frequency every 1 year. There are number of guys, the first one stationed on the star and the others who are at increasing constant intervals of 1 light year with one another.

At any given time, each of these guys will report different color of these stars. esp. For guy1 star may be green, guy2 red, guy3 white, guy4 blue and so on...

Supposing there is a person of almost infinite resource who can simultaneously see what each guys can see at the same time, what exactly (which color of star) is this person seeing.

On bigger scale, a source or power which can see the past, present, future at the same time, what exactly is he seeing. What is there in his consciousness? . Can there be a unified theory to club the events of past, present and future into a single resultant set and to split it back

Why is the quantum world chaotic? Why we cannot describe it with certainty? Why is it uncertain? I agree with Albert Einstein that good does not play dice with the universe. So please explain why is it chaotic… and if you mention something about string theory or the theory of everything in your answers please explain.

Thank you…

Conversely, it's often said there is no Classical analog to Spin. Spin was so named because classically a spinning charged particle would possess a magnetic moment. Isn't this the analog?

Why would Spin have no classical analog, but Orbital Angular Momentum would? Is it because Spin has only 2 states?

It is easy enough to go through and prove there is no paradox in relativity.

Makes sense - it is a mathematical theory derived from established mathematics. People still don't buy it though.

I think the real problem is the conclusion we try to draw from "thought experiments." Creating fictitious situations has a way of masking reality.

Case in point, if you REALLY put a person in a space ship and flew him at half-light speed to a distant star and back, would he really come back that much younger than his earthbound twin?

I'm guessing no, because the simple twin-paradox problem neglects way too many other factors that would actually come into play.

A person jumps from the roof of a house 4.6 m high. When he strikes the ground below, he bends his knees so that his torso decelerates over an approximate distance of 0.70 m. The mass of his torso (excluding legs) is 46 kg. Find the average force exerted on his torso by his legs during deceleration.

The coefficient of static friction is 0.65 between the two blocks. The coefficient of kinetic friction between the lower block and the floor is 0.20. Force causes both blocks to cross a distance of 6.5 m, starting from rest. What is the least amount of time in which this motion can be completed without the top block sliding on the lower block?
