There were quite a lot of Multiverse concepts that we have covered so far. Some of them are really involved, but I hope that my explanations provided a way to conceptually grasp these concepts. There remain only a couple of models which we are not familiar with. Today we shall be talking about a model […]Read more "The Universe as a Hologram"
Now let’s look at what happens when a star reaches the end of its life. Thing is, what happens depends on how big the star is so we’ll look a two stars, an average star like our Sun, and a giant star with several times the mass of the Sun. A star about the size […]Read more "The End is Nigh!"
After I wrote the last piece about resonant orbits I thought I would write a bit about orbits in general and what they are. The fact is that for a long time, a few thousand years at least, we have known that some of the things we can see in the sky go round some […]Read more "The Magic Roundabout"
There is a power in our solar system. A hidden, unseen power that has shaped our Solar System and I don’t mean the Free Masons or the Illuminati! This force has helped make life on Earth possible, and lies at the very foundation of our stellar neighbourhood. The power I am talking about is not […]Read more "The secret power of resonances"
There was once, according to the story, a little girl who fell down a rabbit hole and discovered a strange world where the normal physical rules of how our world works no longer applied. Today we are going to look at what might happen to her great, great granddaughter if she got bored with the […]Read more "Alice’s Adventures in Black Hole Land"
Wow, what a film! Well at least I enjoyed it, I don’t know about you guys. There’s been a lot of talk about the science behind the film and a lot of discussions about how accurate it all was. I make no claims to be qualified to make a judgement on how true any of […]Read more "Interstellar, a look at some of the scientific principles"
About a year ago I read the article in New Scientist considering the question of black hole seeds. It was saying that some of the detected supermassive black holes have the redshift corresponding to the time when the Universe was less than a billion years old. But what’s more important in 2000 Nasa’s Chandra X-ray […]Read more "Primordial Black Holes. Could they have existed? Do they still exist?"
