Amount of kinetic energy in universe

AI Thread Summary
The discussion centers on the sources and calculations of kinetic energy in the universe. It highlights two significant examples: the Milky Way's kinetic energy of 4 e59 ergs due to its movement toward the Virgo cluster and the kinetic energy of electrons around a nucleus, totaling e68 ergs when multiplied by the number of electrons. The complexity of calculating total kinetic energy in the universe is emphasized, as it continuously changes with other forms of energy like gravitational and thermal. The source of kinetic energy remains elusive, likened to the question of the origin of gravity. Overall, the conversation reflects on the challenges of quantifying kinetic energy in a dynamic universe.

What is the source of kinetic energy? Take two calculation that result in a lot of energy. First, if the Milky Way is moving toward the Virgo cluster at 600km/ sec, it has a kinetic energy of 4 e59 ergs. Second, take an electron "rotating" around a nucleus with a ionization energy of 15eV and then multiply by the number of electrons ,e79, for e68 ergs. There are many objects moving and spinning all with significant energy. Here does it come from?

God knows.
 
It would be very hard to calculate all the Kinetic energy in the universe due to the fact it always changing with other energies (gravitational, thermal etc). What is the source of kinetic energy? = Complex question, like saying what is the source of Gravity. Dunno its just kinda there :rolleyes: :eek: :confused: :zzz:
 
What frame do you want to calculate this in?
 
What does "frame" mean?
I think most of the kinetic energy in the universe was caused by gravity acting on matter that was unevenly distributed.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
