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

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

As the name … Continue reading The Shape 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.

 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? 

Forces of Nature Series : Gravity 

Gravity, one of science and nature's biggest mysteries and of all the forces of Nature, the least understood. Out of all the forces Gravity is the weakest and the weakest by far. Gravity, like the other forces of nature, came into existence very soon after the instant of the Big Bang and held its influence … Continue reading Forces of Nature Series : Gravity
