A post qualitatively explaining the main ideas behind the AdS/CFT correspondence. The breakthroughs in theoretical physics due to the theory are outlined along with the consequences for how we view our universe.
A continuation in the series on Black Holes, examining the inner horizon known as the Cauchy Horizon and its implications on space and time.
How quantum fluctuations in the early universe acted as seeds of structure and eventually led to the formation of the galaxies that we see today.
Contains fairly complex ideas and references to previous posts.
An extended piece on the nature of time as a result of the theory of Special Relativity.
Revisiting the theme of time we explain the geometry of spacetime and explore the special quantity known as ‘proper time’. A qualitative post which includes the use of simple graphs.
A post about the Event Horizon Telescope and its recent efforts to capture the first ever image of the Black Hole at the center of our galaxy.
Today we follow on from the first in the series on Black Holes (#1 Falling In) and talk about how black holes aren’t thought to be that black after all with the idea of Hawking Radiation. The post will then cover how, as a result of this radiation black holes are thought to evaporate and as a result shrink!
Today we venture to the dark side in order to bust some myths on the two most mysterious and shady characters in our universe: dark matter and dark energy.
Entropy is the level of disorder – but that definition can lead to some misleading ideas. Sometimes it is easier to think of it as being the tendency for things to wander over time. I hate to use this phrase, but it is a tendency towards randomness.
What really is a coincidence? Is there one unified way in which all of the coincidences in the universe can be understood, or are we left with an uncomfortable illusion of luck?
