One of the most common headlines I see in popular science articles is "Was Einstein Wrong?". While it is certainly true that relativity is going to be replaced by some more advanced theory of physics at some stage, the basis of Einstein's theory is unlikely to change.
So how do we explain the fact that there is more matter than antimatter in the universe? The fact is that currently, we don't know. This is called the "baryon asymmetry problem" of cosmology.
While it's always healthy to be sceptical about things and to re-examine the evidence supporting your science, it seems a worrying number of people are taking this far too far. The bottom line is that there is a wealth of evidence that supports the Big Bang theory which no other known theory can explain.
Here's another video. I'm often asked how there can be no God if the chances of our planet being habitable are so slim. This is the reason why.
Here's a fascinating thing I learned about recently - how simple the origins of electromagnetism are.
In particle physics we have one of the most accurate and successful theories ever - the Standard Model - but there are many things about it that seem "out of place".
Symmetry may be very familiar and intuitive to us, but how can we talk about symmetry mathematically? We know that triangles and spheres both possess kinds of symmetry, but how are they related? The mathematics of symmetry can be described by "Group Theory".
Well, I'm trying my hand at making videos with my trusty whiteboard. Here's a video of me rambling about the nature of light.
It's a phrase you'll often hear if you try and press physicists for answers to the most difficult questions. "What happens at the center of a black hole?", "What happened in the first moments of the Big Bang?" Modern physics is currently not advanced enough to be able to give answers to these questions.
I think that "atheism of the gaps" is a legitimate fallacy, but not one that atheists often make. I think this term has the annoying potential to be thrown incorrectly at atheists if it starts becoming mainstream.
