Signs Of The Zodiac Series

I admit, last weeks post was slightly shorter than most other posts I’ve ever written. Following on from this I have decided to complete a series on the signs of the zodiac from the point of view of astronomy. The Zodiac are the star groups and systems can observe from Earth depending on the time … Continue reading Signs Of The Zodiac Series

Will The Universe Expand Forever?

Will the Universe expand forever? A frequently asked question in the comments on the website. I touched on this in the past during the cosmology and dark energy topics covered in previous posts but it certainly deserves a post in its own right. Cosmology deals largely with the universe as a whole considering all the … Continue reading Will The Universe Expand Forever?

Dark Flow

At the instant of the Big Bang, the universe began its inflation. Expanding outwards in all directions faster than the speed of light before cooling and forming all the bodies we can observe now. For decades it was assumed that the velocity and distribution of galaxy clusters should be pretty even across the universe with … Continue reading Dark Flow

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

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.
