I apologize if this comes off as a dumb question, but does anyone know if gravity is ABSOLUTELY simply dependent on density alone, regardless of the type of material itself, or does the type material also factor into it's gravity?
So does this mean that light will always reach us, and that light always moves at the same speed, but it just gets down graded in frequency from the "visible spectrum" to one undetectable by known sensors?
And to pony off that question, since it has been one I have always wondered about...
@ juvenal; I don't mean to troll this thread on too long with questions, but I had a bit of a misconception also and I thought the bowling ball analogy was a pretty good one. So just to be clear with what I have read so far- considering a single photon to be the bowling ball- is the frequency of...
Agreed, you can't simplify this one to just a basic formula. The variables mostly come from the variable that is the horses themselves. Being that each one is different, each one performs differently. They have a different "gait"- for lack of a better word- angle of contact with the ground...
In his theory, Stephen Hawking suggests that a black hole will give off thermal radiation. Radiation is light, so how can light escape the gravity of a black hole, especially originating from one? The only way I could see this was that if radiation were traveling beyond the speed of light, but...
I understand that an electron can gain and lose energy, but before this, the electron is spinning around the nucleus of an atom. Since motion requires energy, what is the energy that keeps the electron spinning.
Further- since there is loss in every system- if no energy is applied or taken...
