Light itself has temperature. If you let it fall upon a cold black body long enough, the body would warm up to that temperature and emit light of that temperature itself. What's the temperature of sunlight on the earth? About 5000K. It's the temperature that the surface of the sun had about 8 minutes ago. The sun could have extinguished 8 minutes ago, but ...
The temperature 2.73 K is not calculated, it is measured. The cosmic microwave background (CMB) has the properties of a blackbody radiation at the temperature 2.73 K. It is based just on the measurement of CMB, no calculation of dark matter or dark energy is involved. Temperature does not simply depend on mass or gravity. Temperature is a quantity which in ...
Mass in and of itself will not generate heat. Heat comes about when two objects interact with each other i.e. when they change from one state with a given energy to another. More specifically, if an object has more energy after an event than it did before, the net gain in heat would be negative for the surroundings (the environment becomes colder), and vice ...
No. You have just named a series of unanswered questions as if the fact they're unanswered somehow invalidates the Standard Model. This is not in general how science works. For the extensive evidence for the Standard Model, please see http://arxiv.org/abs/hep-ph/9810316 among many other things.
