The Importance of Uncertainty

It is not difficult to find online forums and blog posts that proclaim facts and arguments as if they were certain. People of all philosophical alignments will do this. Theists will proclaim what they believe to be indisputable facts like: "Something must have caused the Big Bang", and atheists are often guilty of prophetically declaring their favourite origin story for the universe: "Quantum fluctuations produced the universe" or "Many-worlds explains fine-tuning".

Do Space and Time Really Exist?

There is a split in the philosophical community with regards to this issue. By and large, the majority of philosophers of physics claim that space and time are real and important entities, but there is a small faction who maintain that space and time are just useful theoretical constructs that don't have the independent existence we sometimes attribute to them.

Why The Universe Had No Beginning

It is almost certainly the case that time behaved differently at the Big Bang singularity to how it does now, and that it is not possible to define a time "before the Big Bang". Defining a time before the universe would be nonsensical anyway because time is a part of the universe, not external to it.

Universes of Another Kind

There are other kinds of multiverse that physicists discuss, but there's an entirely different kind of multiverse that is discussed by philosophers, not physicists. This is the multiverse of "possible worlds", and was introduced as a semantics that made modal statements much easier to analyse.

Black Hole Fun

If it's possible to have a favourite astronomical object, I'm sure black holes would be fairly high on everyone's list. You can't escape from one, you can't know what's inside one, and they're invisible - what could possibly be more terrifying and exciting to talk about?

Consciousness Has No Place In Quantum Physics

While I will be quick to point out that a theory of quantum mechanics based on consciousness has not been ruled out, it is certainly not the only way to formulate the laws "in a fully consistent way". Pilot wave theory, GRW collapse theory, many-worlds theory, and decoherence theory are all consistent attempts at trying to make sense of quantum mechanics.
