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.
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".
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 really wish people would stop planting the laws of thermodynamics in their arguments as if they're an irrefutable line of defence. Thermodynamics is 19th century physics, we've moved on.
It takes a fair few years of a university degree to begin to realise that symmetry is perhaps the most fundamental concept in modern physics. It's no accident that one of the leading candidates for new physics is called "Supersymmetry".
