Last week I wrote about the WOW! Signal. The most likely candidate for a formal effort of contact from extra-terrestrials due to its irregular and almost artificial qualities. This does pose a thought, are radio waves the best way to establish contact? Although radio signals are received by radio telescopes every day, some are extremely … Continue reading Using Radio Waves and Other Means To Make Contact.
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.
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
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
