The Day The Earth Stands Still

A year is 365 days, one full orbit around the Sun. A day is one full turn on the Earth's rotational axis. So what would happen if the Earth's rotation just suddenly stopped?  If the Earth stood still suddenly, everything not attached to the crust of the Earth would just be swept up into the … Continue reading The Day The Earth Stands Still

White Holes

In the mathematics of Einstein's Theory of Relativity, black holes are predicted and astronomers have proven beyond all doubt that they exist. The centre of our own galaxy harbours one of these monstrosities and so do nearly all galaxies observed.  In the same mathematical models which predict black holes, there are predictions for entities which … Continue reading White Holes

The Orion Nebula

On a clear night with the naked eye, we see what we believe to be stars scattered in every direction across the sky. With binoculars or a small telescope, we can see some of these "stars" are not actually stars at all but star forming regions. The prettiest of these is also our nearest, the … Continue reading The Orion Nebula

If The Sun Suddenly Collapsed into a Black Hole.

Black holes seem to have captured the imagination more so than all other cosmic bodies or phenomena. Blockbusters like Interstellar and Event Horizon have certainly increased the profile of black holes and worm holes. With a captured imagination comes misconceptions and inaccuracies.  To begin, most physicists believe black holes aren't even holes at all! Black … Continue reading If The Sun Suddenly Collapsed into a Black Hole.

The Shape of The Universe.

Cosmologists have been debating the shape of the universe for decades. From simple observation we know the spherical shape of Earth, stars and other celestial bodies. Although, what shape is the entire universe the galaxies are embedded in?  In cosmology, a difference is made between the observable universe and the global universe. As the name … Continue reading The Shape of The Universe.

The Edge of The Universe. 

Where is the edge of the universe? Most importantly, what happens if we try to get there? Let's state the obvious, surely there can be no edge to our universe if the universe is infinite. On the other hand, how can it be part of our universe if we can't interact with it? After all, … Continue reading The Edge of The Universe. 

Why Is The Speed of Light Finite? 

 In the past year of blogging for GLAMsci, the most questions and feedback came from the speed of light series so I thought a bit of housekeeping was in order to post another blog relating to it.  To be fair, in my posts I discussed the finding of the speed of light and how it … Continue reading Why Is The Speed of Light Finite?
