Coldest – Boom­erang Nebula 1K The coldest place outside of a labor­atory is the Boom­erang Nebula at 1K or minus 272.15°C, which is even colder than the Universe’s back­ground tem­per­ature of 2.7K. Hottest – Col­liding particles in Large Hadron Collider 1000000000000000000K … Continue reading →

Slowest  –  Con­tin­ental Drift 0.0000000003m/s The average relative speed of con­tin­ental drift is about 10mm per year. At one time all the current con­tin­ents were joined together in one super­con­tinent called Pangaea but over Earth’s 4.5 billion year history this was broken apart … Continue reading →

Lightest  –  The Electron Neutrino 0.0000000000000000000000000000000000036kg The electron neutrino is so light that it’s very dif­fi­cult to detect; any detector needs to be buried deep under­ground where other particles can’t reach it and it needs to be very, very big. The Super Kami­okande … Continue reading →
