Alongside black holes and white holes, wormholes have held a position of wonder in real physics as well as science fiction. A wormhole is a theoretical cosmic object that connects two different points in space and time. As per Einstein, wormholes could theoretically connect two different universes. American physicist John Archibald Wheeler coined the term … Continue reading Wormholes Series : Intro
When going through the questions and comments of the recent Zodiac series, I found a lot of questions regarding the spacetime interval and realised I didn't go into it in any great detail in last years relativity series. Silly me! When I discussed the spacetime interval in the past, I explained it in the mathematical … Continue reading The Spacetime Interval.
On the 11th of February 2016, the Laser Interferometer Gravitational Wave Observatory (LIGO) announced that they had detected the first evidence of the existence of gravitational waves the previous September. At the time this was a massive triumph for the team that observed them and made headlines worldwide. So what are gravitational waves? In 1916, … Continue reading Gravitational Waves
Cancer, also known as "the dark sign", is a medium sized constellation surrounded by Gemini to the West, Leo, Canis Minor and Hydra. The Brightest star in Cancer is Beta Cancri which only has an apparent magnitude of 3.5. So it's brightest star isn't overly bright and neither are the rest of them hence the … Continue reading The Constellation Cancer

Will the Universe expand forever? A frequently asked question in the comments on the website. I touched on this in the past during the cosmology and dark energy topics covered in previous posts but it certainly deserves a post in its own right. Cosmology deals largely with the universe as a whole considering all the … Continue reading Will The Universe Expand Forever?
Winter is here and with that brings what we believe to be freezing cold weather. The freezing point of water and what we interpret to be freezing is 0 degrees. This isn't absolute cold as there are negative temperatures both in the Fahrenheit and degrees selsius scales. To get to absolute cold we need to … Continue reading Absolute Cold
