18. “The marriage of space & time" 👰🏽 When I’ve sat in front of my computer staring at the same piece of code for weeks on end, I like to remember the especially beautiful way that Prof #hawking
described our field, cosmology- “the marriage of space and time”❤️. We study a branch of astrophysics that, instead of dealing with one phenomena that we can observe, considers the entire Universe as a whole, from origin to its fate. There are a wealth of mysteries at every stage! We have a standard model of cosmology and it is governed by a theory of gravity. This in itself is remarkable, that in our blip of existence in cosmic time, technology allows us to observe objects at distances beyond our comprehension and that our measurements even vaguely fit a consistent model. However, while it robustly stands up to most of the observations, there are cracks and things that don’t quite add up! As such, we build bigger telescopes to refine our model, in hope that we may one day have answers to the most fundamental questions of our Universe. ❓It is fascinating and keeps you on your toes, especially as humanity’s understanding of the universe has evolved at a much faster rate than the Universe does! From Copernicous revolutionising the idea of our place in the Universe, to Einstein upgrading Newton’s laws of gravity (post on this imminent!), what new idea will blow our minds next?! 🤯 The image is a computer simulation of the distribution of luminous and dark matter- the large-scale structure- of our Universe, courtesy the Millennium Simulation Project.
