The Night the Universe Changed

“I conclude, therefore, that this star is not some kind of comet or a fiery meteor… but that it is a star shining in the firmament itself one that has never previously been seen before our time, in any age since the beginning of the world.” -Tycho Brahe I want to take you back in…

How to find your very own supernova

“Do you see the absurdity of what I am? I can’t even express these things properly because I have to – I have to conceptualize complex ideas in this stupid limiting spoken language! But I know I want to reach out with something other than these prehensile paws! And feel the wind of a supernova…

“I wouldn’t dream of working on something that didn’t make my gut rumble and my heart want to explode.” -Kate Winslet Welcome back for another Messier Monday! At the start of each week, we take a detailed look at one of the 110 deep-sky objects that make up the Messier Catalogue. This week, we’ve got…

Giving thanks for our place in the Universe

“We live in an atmosphere of shame. We are ashamed of everything that is real about us; ashamed of ourselves, of our relatives, of our incomes, of our accents, of our opinions, of our experience, just as we are ashamed of our naked skins.” -George Bernard Shaw All that is real about ourselves is nothing…

The only…

“There is a single light of science, and to brighten it anywhere is to brighten it everywhere.” -Isaac Asimov One of the most spectacular and successful ideas of the 20th Century was Einstein’s General Relativity, or the idea that matter and energy determines the curvature of spacetime, and the curvature of spacetime in turn determines…

“Black holes, which have no memory, are said to contain the earliest memories of the universe, and the most recent, too, while at the same time obliterating all memory by obliterating all its embodiments. Such paradoxes characterize these strange galactic monsters, for whom creation is destruction, death life, chaos order.” -Robert Coover Our Milky Way,…

This is an enhanced version (with some upgraded images and text) of an article I first wrote over two years ago. It is just as valid today as it was back then, only today, I have a special offer to go with it. Next week, a bunch of cosmologists and myself are getting together and…

“Everyone must leave something behind when he dies, my grandfather said. A child or a book or a painting or a house or a wall built or a pair of shoes made. Or a garden planted. Something your hand touched some way so your soul has somewhere to go when you die, and when people…
