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 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
Copernicus
In this post I'll talk about Nicolas Copernicus (1473 - 1543) and the heliocentric theory. The move away from the prevailing Earth-centred theory of the Universe to the heliocentric theory represents one of the greatest advances in astronomy ever made. Nicolas Copernicus - Image from Wikimedia Commons Background - the need for a better theory… Continue reading Copernicus
Short post of the month February 2016 – gravitational waves
The subject of February's short post of the month is gravitational waves. These were predicted by Albert Einstein back in 1916, and after decades of searching have finally been detected. In an announcement made on 11 February at a Washington DC press conference David Reitze, the executive director of the LIGO Laboratory, said: “Ladies and gentlemen, we have… Continue reading Short post of the month February 2016 – gravitational waves
The Steady State Theory
This post, the latest in my series about cosmology, talks about the Steady State theory. This is an elegant alternative theory to the Big Bang, which was very popular among astronomers in the 1950s, but is now obsolete. What is the Steady State Theory? The Big Bang theory states that the Universe originated from an… Continue reading The Steady State Theory
