Why Can’t We Travel Faster than the Speed of Light? – This might be news to some of you but if you’re familiar with Einsteins theory of relativity, and that most famous of equations E=mc2, you’ll understand the limitations imposed by the equation. But exactly why should it be like this ?
One of the most common and baffling science questions is “how does gravity work?”. If you too find yourself confused then rest assured you’re in good company … even Sir Isaac Newton admitted he was baffled by gravity. In this article we look at Einsteins solution to this conundrum.
In a nutshell … tides are caused by the gravitational attraction between the moon and the Earth. In this article we look at how.
In the days of analogue TV you turned into a channel through various UHF frequencies. If you stopped tuning before you found a channel, you’d see a screen full of ‘snow’ – white dots . Some of that ‘snow’ is a sign of the Big Bang , although nobody was aware of its significance until the 1960s.
How and when did the Earth acquire the Moon? Much light has been shed since the Apollo moon landings and more recently when super-computers have enabled more detailed modelling to take place.
An odd question and an even odder answer when we say that it’s because “you can’t unspill milk or unshatter a glass”. In this article we explain what this means.
We know that the Earth’s core is hot, but not how hot. Actually, even geologists don’t know exactly what the temperature is, either, but they know it is almost as hot as the sun. Now that’s hot ! In this article we look at what’s going on down there and why it’s so hot.
So here’s a question you might idly contemplate as you lie back one summers evening gazing into star bright night sky watching as the planets, the moon and the stars idly move on by, “Will the Earth ever stop spinning ?”
Up until the mid 16th century the predominant view was that the Sun revolved around the Earth. It wasn’t until Nicolaus Copernicus (1473-1543) and later Galileo Galilei (1564–1642) came along that a heliocentric model of the Solar System was able to triumph. In this article we look at the seminal moment our understanding of the Universe changed!
Why is there something rather than nothing ? Or to put it another way why do we and for that matter the Universe exist ? These kinds of questions along with their proposed answers form a ‘set’ of philosophical conundrums known as The Cosmological arguments. The Cosmological Arguement Question : Why is there something rather than nothing? Answer : God Such are the beginning and end of the cosmological argument, and there...
The Universe is an amazing place ! Just how amazing is hard to comprehend sometimes. In this article we look at some astounding things happening in the Crab Nebula.
Why is the sky dark at night ? A stupid question, surely ? … not really when you consider how the universe and space are operates.
The pursuit of science is based on the belief that the explanations we seek are comprehensible to the human brain. But supposing they’re not? What if no human brain is well enough equipped to understand the universe. What if we are fooling ourselves?
