t’s no secret that the universe is an extremely vast place. But can we calculate how many atoms it contains?
According to the big bang theory, the universe started off as an infinitely small point and expanded incredibly quickly in a process called inflation. But why is the Universe still expanding ?
A team of German scientists examining material from the seabed beneath the Pacific Ocean believe that they may have uncovered explosive evidence of an event that altered the evolution of humankind.
How Did Something Come From Nothing? : Questions do not come much deeper than this and until the 1970s only theologians and philosophers felt able to take it on (plus physics students still in the bar at closing time)
Cosmic Questions : How big is the universe? ; How fast is it expanding? ; Where is the force coming from? ; Where is the centre of the universe?
We consider some BIG questions in this article, however beware, not all the questions have what you might consider satisfactory answers.
When we say ‘the Moon’ we don’t mean OUR moon but another in our solar system. Researchers in the U.S. have got a close look at what they’re calling ‘the weirdest moon in the solar system’
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.
