Is the Universe Ordered?

Order is a slippery concept, it can mean several different things depending on what you're talking about. Because its meaning can be subtle, the term is often misused. I hope in this article to shed a bit of light on how we can understand what order is in physics, and whether it can be applied coherently to the universe as a whole.

Is Time a Part of the Universe? A Clarification

This is why I say that the universe must contain time. The universe is best thought of as a static 4-dimensional shape of which slices are all we can perceive. What really bites is that we all perceive different slices of this 4-dimensional shape, and how would that be possible if the universe were only 3D?

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.

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?
