He took the Copernican model of the universe and took it to absolute extremes. While the Earth … Continue reading Tell Us How the Heavens Flow: the Life and Execution of Giordano Bruno (Blog #3) → Continue reading → Continue reading

The naked eye was enough to understand basic astronomical phenomena in the solar system, but if we wanted understand more, the human eye would need some help. Although they were primitive and only had magnifications of around three … Continue reading Of Light and Glass (Blog #2) → Continue reading → Continue reading

Although not the first to do so, Copernicus devised a new model for the … Continue reading Copernicus in Context → Continue reading → Continue reading
As of the time of writing, Voyager 1 is over 21.1 billion kilometers away from its launch point of Earth. This distance seems long to most, but in the grand scheme of things it is almost nothing at all. This distance represents only 0.2% of that of a lightyear, meaning that a photon released from … Continue reading Speck of Dust and Cosmic Sand (Blog #1) → Continue reading → Continue reading
