Due to time dilation one could travel thousands of light years in a human lifespan without exceeding the speed of light. A full 40 year trip at 1 g will appear on Earth to last 58,000 years and cover a distance of 55,000 light years.
If the strange matter hypothesis is correct, it is speculated that a strangelet coming into contact with an ordinary lump of matter could convert the ordinary matter to strange matter. In a disaster scenario, all the nuclei of all the atoms of Earth are converted, and Earth is reduced to a hot, large lump of strange matter.
Chadwick (the discoverer of the neutron) was a student of Rutherford (discoverer of the proton) who was the student of Thomson (the discoverer of the electron).
It takes a photon 170,000 years to travel from the core of the sun to the surface, but only 8 minutes to travel the rest of the way to earth.
A UCSD scientist used physics to get himself out of a $400 traffic ticket. He was issued a traffic ticket for failing to completely stop at a stop sign. Instead of paying the ticket, the physicist fought the citation by writing a four-page paper explaining how the ticket he was given defies physics. The paper explained how what the officer “thought” he saw, he didn’t really see, according to the laws of physics.
Physics Professor Jack H. Hetherington learned he couldn’t be the sole author on a paper. (because he used words like “we” “our”) Rather than rewriting the paper he added his cat as an author.
When you crumple up gift wrapping it makes a shape so complex that it will defeat even the most sophisticated computers.
An electric bell has been running off the same battery for 170 years and no one knows what the battery is made of.
