This is an introduction to CCC theory, a theory by physicist Roger Penrose that suggests that the universe had no beginning.
My prediction comes true
Over three years ago, I made a video, predicting CCC theory would become mainstream cosmology, now three years later all space news outlets are reporting this theory, making it mainstream. It did take them some time, journalists these days.
This strange theory is by physicist Sir Roger Penrose and entails that the universe has gone through many big bangs, not just one, from the infinite past.
The three key things of Conformal Cyclic Cosmology are
Hawking Points are evidence of a previous universe located in the Cosmic Microwave Background, which could be remnant signals from Supermassive Black holes from a previous aeon.
Hawking Radiation is the radiation from those supermassive black holes that evaporated.
Conformal Geometry ...well, is strange.
According to Penrose, as the universe increases in size, the universe forgets its size, it changes to this conformal phase and essentially big and small have no meaning anymore. So, the radiation from the black holes that evaporated from the previous aeon, can now interact and that forms quantum fluctuations, so we're back at the "beginning" and a big bang arises. This is the same universe and according to Roger, this will also happen again in the future for infinity and has happened infinity in the past.
So, let's recap.
The Universe goes through cycles of Big Bangs.
Radiation from Supermassive Black Holes is used as evidence of a previous aeon, so-called Hawking Points.
The Universe forgets its size - changes to conformal geometry.
Due to the conformal phase, the Hawking Radiation is able to interact as essentially the Universe is very small in this unique phase, so will not die of heat death.
And that's a simple explanation of this very strange and fascinating theory.
