Climate Change (AKA Global Warming)

Any clue as to why bouncing branes appear to produce only energy in all its different forms.
What is all the energy for?
Average temperature of the universe is what?
"It has a temperature of 2.735 K (-270.415°C)."

Could we be living in "god's" fridge?

I don't think thinking of it as a "fridge" is particularly helpful.

If you assume that you start with nothing - no energetic interractions of any kind - then you are at absolute zero. Add a photon, propagating it's merry way through space, and you have added a measure of energy - a temperature to it. Most of the Universe is ass-numbingly cold in our reference frame because very little happens there, as judged from the sum total of our perspective.. (As in, a lot still does happen, but there is generally "more stuff that does stuff" at the point between these *point* two hairs on my forearm than at a similarly-sized point somewhere between the Sun and Betelgeuse)

The energy is not for anything. It exists, and due to its existence, things like matter can arise.

In his lifetime, it has been estimated Sir David has travelled 1.9 million miles – the equivalent of flying around the world 763 times – and has made almost 400 trips to 94 different countries. As at 8 Dec 2020.
