The phrases "what is that in old money?" or "what's that in mph?" can often be heard up and down the country but to be honest mostly in retirement homes nowadays. It is true that some of those who grew up using Imperial measurements don't like these newfangled meters and kilograms but the clincher in... Continue Reading →
The Age of the Universe
This is quite a long read but that is both appropriate and relative because the Universe's lifespan is also long, I mean LOOOOONG. Never has the phrase "as old as time" been quite so appropriate as it is when talking about the age of Universe. It would be fair to say the Universe is long... Continue Reading →
The Extraordinary Story of Women in Science (part 2)
The top 5 female scientists. The story of these women's achievements is remarkable. We have biologists, chemists and physicists. Some recognised, most not. Can you guess the top 5?
The most embarrassing mystery in science.
Matter only makes up 4 percent of the Universe. A further 23% of the Universe is made up of dark matter and the final 73% is dark energy. Would you like to know exactly what dark matter and dark energy are? Yeah, so would scientists. That's right, they make up 96% of the Universe and we don't know what they are, more than a little embarrassing.
How to build a time machine.
There are many possible ways to time travel. Steal a TARDIS, build a flux capacitor or take up too many classes at Hogwarts to receive a time turner. How about something more realistic? Well this video demonstrates how we can use Jupiter to build a time machine: https://www.youtube.com/watch?v=qkQbLEKM3QU&t=34s OK so we are playing fast and... Continue Reading →
How we know there are HUNDREDS of alien civilisations in our galaxy.
In 1961, the first meeting of SETI was called. If you are unfamiliar with SETI, it stands for the 'Search for ExtraTerrestrial Intellegence' and it does what it is says on the tin really, searches for extraterrestrial intelligence or aliens. Now the problem was where to start, the Universe is huge, the galaxy even is... Continue Reading →
With a bang or a whimper? How the Universe will end.
The fate of the Universe ultimately depends on how much stuff is in it, how fast it is expanding at the moment and scientists favourite fudge factor, dark energy (otherwise known as the cosmological constant). Now the nature of dark energy, or similarly dark matter, is unknown. In fact whether they exist at all has... Continue Reading →
Why Venus is the odd kid on the block.
Our solar system formed from a huge cloud of dust and gas, that was probably a remnant of a huge star that decided to opt for bang rather than whimper in leaving this universe. As this maelstrom a star guts began to collapse in on itself under the relentless pull of gravity it started to... Continue Reading →
Easy ways to create artificial gravity on a spaceship
I use the word easy based on the fact that if you have successfully built a spaceship the next steps should be a doddle. If you've never even built an IKEA bookcase then you may need another adjective. First out of the blocks we could simply use another force in place of gravity. Electromagnetism is...

Is the Earth really round…?
Scientists would have us believe that the Earth is round, but is it actually round?
