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
A little bit of housekeeping is in order. Technically speaking I probably should have started with Capricorn but given Aquarius is in January I started with that. Nonetheless, the Sun in our series will have gone through all the signs of the zodiac on its journey around the ecliptic. As we have started housekeeping I … Continue reading Finale – The Constellation Capricorn.
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
Scorpius, more commonly known as Scorpio in astrology, lies between Libra and Sagittarius on the Sun's journey of the ecliptic. Although the constellation is seldom called Scorpius officially, it is the correct name. The sun is only within the bounds of Scorpius for 6 days from November the 23rd until the 28th.Scorpius is Latin for … Continue reading The Constellation Scorpius
