As discussed in my previous two posts our Universe appears to be very finely tuned and is governed by four fundamental interactions. A relatively small increase or decrease in the strength of one of these interactions, such as making the force of gravity weaker or stronger, would make the emergence of life impossible. The four… Continue reading Our finely-tuned Universe part III – Explanations for fine tuning
In a previous post I talked about the four forces which govern the way the Universe works. I’m now going to give some examples of fine tuning. How different our Universe would be if these four forces had very different relative strengths. But before I do this, it is worth giving a quick summary from… Continue reading Our finely-tuned Universe part II – Examples of fine tuning
This is first of a series of three posts in which I'll talk about the idea that the fundamental forces which govern our Universe and fundamental constants such as: the strength of gravity, the electric charge of the electron and the amounts of matter, dark matter and dark energy in the Universe have been in… Continue reading Our Finely-tuned Universe Part I-Fundamental forces
In his 1988 book 'A Brief History of Time' the British theoretical physicist Stephen Hawkins (1942-2018) stated: 'The laws of science, as we know them at present, contain many fundamental numbers, like the size of the electric charge of the electron and the ratio of the masses of the proton and the electron. ... The… Continue reading The anthropic principle.
