The speed of light is as frustrating as it is fascinating. The speed of light in a vacuum is the fastest thing we can measure at 300,000km per second, although in a vast and ever expanding universe, it is painfully slow. The universe currently measures 45 billion light years in all directions of observation. So … Continue reading The Speed of Light – So Agonisingly Slow.
Using Radio Waves and Other Means To Make Contact.
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.
Extraterrestrial Contact Series Part 1 – The Wow! Signal.
All over social media, there are articles discussing radio signals from other galaxies and stellar systems. The number one rule in astrophysics and cosmology is - IT IS NEVER ALIENS. A lot of radio signals can be interpreted and can have natural sources; rapidly rotating neutron stars, supermassive black holes and so on. So how … Continue reading Extraterrestrial Contact Series Part 1 – The Wow! Signal.
Cosmic Water Series Part 3 – Water in The Early Universe.
By Jude Morrow My latest two blog posts regarding surface water on Mars and Titan seem to have generated an influx of questions. When researching material for blog series’, the questions and comments seem to give inspiration for future posts. One such comment mentioned a large reservoir of water located at a proper distance of … Continue reading Cosmic Water Series Part 3 – Water in The Early Universe.
Cosmic Water Series Part 2 – Saturn’s Moon Titan.
Of all the bodies in our own solar system, Titan is definitely my favourite. The reason being, it is one of the most likely candidates for life. I'm sure plenty of subscribers are rolling their eyes thinking; here he goes about Titan again. For this series it is quite relevant as Titan almost certainly contains … Continue reading Cosmic Water Series Part 2 – Saturn’s Moon Titan.
The Andromeda Collision
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 Using Wormholes.
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.
Wormholes Series : Intro
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
The Spacetime Interval.
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
