1. Construct a physical explanation for why the sound of thunder from a lightning strike appears after the actual bolt is seen.
2. Execute a strategy that would allow you to determine the distance to a lightning strike, given a five-second time difference between seeing the lightning and hearing the thunder.

Name a time that the universe had no matter in it. you should refuse to use that dirty BB word. A true vacuum void is impossible the container would never be strong enough to stop matter entering into the void, then how do you have right next to this impossible void all the matter in the universe coldly crammed into the size of a pea or a tardis, (Dr who fans need not reply)

"By now you should be seeing that the two cannot exist along side each other"

a pea under the extreme pressure of containing all the mass of the universe and a impossible vacuum, it is impossible because the observer contaminates the observed and it would take more than the all the energy in the universe to create and maintain.
This is all happening before energy exists? This does not take into account the energy needed to cram all the mass of the universe into our pea size tardis, where did all this energy come from before energy existed. i wish someone would pull the STRING on the BB theory.

I understand that only the male crickets chirp and that they do so to either call out their territory or to attract females. I have also read that the cricket chirps vary by species and actually speed up or slow down in relationship to the temperature. My question is "Why is the chirping constant and not more sporadic?"

The Earth's atmosphere mimics its shape. If the Earth was flat would we just have a dome-like atmosphere on the top habitable side or would there still be the circular atmosphere, as if the Earth was a thin disc suspended in the middle of a circle.
Agh, headache! I know what I mean!

A mess of questions to indicate my mess of understanding.

Why is the speed of light a constant?

Does this exact figure correspond to mass requiring an infinite amount of energy at that given point, can't it actuall happen ever so slightly before or after this speed?


Is the speed of light an arbitrary marker used by physicists?

Is there an inhibiting factor to non-rest particles beyond this speed? Why this particular speed? It just seems so arbitrary.

I just div'nae understand.
