First of all, apologies for the lack of posts in recent weeks. I have been looking into the comments and suggestions on the website for several weeks to gain inspiration for new posts. I've done plenty of posts explaining the curvature of space and time, the movement of the heavenly bodies and how the fabric … Continue reading The Andromeda Collision
Time travel has been a key component of science fiction for literally hundreds of years. In our reality, or should I say interpretation of it, is time travel actually possible? Kip Thorne, the most recent Nobel Laureate for physics certainly seems to think so. Thorne theorises that interstellar travel is possible via a wormhole. Thorne … Continue reading Time Travel Using Wormholes.
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
Sagittarius lies at the centre of the galaxy and is represented in mythology as a Centaur pulling back a bow. From the northern hemisphere, the brighter stars are easily recognised from an asterism known as the teapot. The brightest star in Sagittarius is Epsilon, a rapidly spinning binary star. At 143 light years from us, … Continue reading The Constellation Sagittarius
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
Gemini, known as the "Heavenly Twins", is one of the easiest constellations to recognise with over 80 stars visible without a telescope. For astronomy it is one of the most examined constellations due to its diversity. It is rich with various types of stars, galaxies, meteor showers and planetary nebulae. In Greek mythology, Castor was … Continue reading The Constellation Gemini.
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?
