Event Horizon was a somewhat dodgy sci-fi-horror movie that came out in the late 1990s. As the title suggests, associated with an Event Horizon is "Infinite Space, Infinite Terror". Luckily, the Event Horizon in the film as a black hole Event Horizon, and I'll leave discussing those to another time. Today, we'll try and understand the Cosmological Event Horizons. To explain these, I am shamelessly going to use the (still) excellent cosmological figures produced by Tamara Davis . OK, let's start with this one. To understand what this picture is telling us, we need to remember a few things. Our universe has three spatial dimensions, and any spatial point can be labelled with three numbers. In a Cartesian coordinate system , these are (x,y,z). As we are dealing with relativity, we are dealing with not only space, but space-time, and every point in the universe is labelled by 4 numbers, the three spatial coordinates and the time, t. So, every point is labelled...
Personally, this "big science" idea doesn't appeal to me at all. I'd much rather potter away in a corner on my own things. Which require me to program well.
ReplyDeleteBut you have big science papers - with monitoring of quasars for reverberation mapping!
DeleteTouche. :) They aren't the ones that I identify myself with, but they are some of the most cited.
DeleteAh! So, you outsource your Big Science! :)
