Fake Astronomical Images

A friend of mine, the active amateur astronomer Colin Henshaw, brought the following photograph to my attention. It appears to show the Moon rising over Mossel Bay in South Africa. Although it was passed off as a genuine image, for reasons which Colin pointed out, it is a fake. If you study the Moon, it… Continue reading Fake Astronomical Images

Our finely-tuned Universe part III – Explanations for fine tuning

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

Our finely-tuned Universe part II – Examples of 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

June 21 2022 – the solstice

This year, the June solstice will fall on 21 June.  As most people know, In the northern hemisphere, it is the day of the year when there is the most daylight and when the Sun is at its highest in the midday sky. The origin of the word solstice is from two Latin words:  sol, which… Continue reading June 21 2022 – the solstice

Our Finely-tuned Universe Part I-Fundamental forces

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
