In his Special theory of Relativity, which we were considering in the previous chapter, Einstein resolved the physical conflict which regarded the speed of light and our intuitive understanding of motion. He showed that our perceptions of motion need be changed when we are talking about objects that are moving extremely fast. However, soon after […]Read more "String Theory – Part 3: General Relativity – The Heart Of Gravity"
In our Multiverse journey we’ve passed down a long road through Friedman’s expanding Universe, inflationary cosmology, quantum mechanics, superstring theory and even thermodynamics. What combines all of these concepts is that they’ve come to our attention through physical laws. Some of the considered theories have been confirmed to an extraordinary level of precision, while others […]Read more "The Simulated Multiverse"
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!"
Right now, in the early evening, it is possible to see the closest planet to the Sun, Mercury. Assuming there are no clouds, in which case you probably don’t live very close to me! Mercury is not only the closest to the Sun, it is also the smallest planet but strangely enough, not the hottest. […]Read more "The Incredible Shrinking Planet"
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"
A few weeks ago I was talking about the concept of Brane Multiverse which gains attention of physicists concerned with the superstring theory (or, equivalently, with the M-theory). Then, I showed how the Cyclic Multiverse model was improved upon the notions of this theory. Today our goal is to have a look on another Multiverse […]Read more "The Landscape Multiverse"
