A couple of years ago I noticed pits on my glass slides after laser tattoo treatments.

How long does it take a new photon to reach us from its creation in the sun?
All of the sun’s photons are generated through nuclear reactions within it. If a photon is generated at the centre of the sun it can take anywhere between 2 days and 200,000 years to escape the body of the sun. That’s because the path of the photon is purely probabilisitic. At the centre of the… Continue reading How long does it take a new photon to reach us from its creation in the sun?
How fast is the Earth moving through space?
Ever wondered just how fast we are moving through space? Well, the Earth revolves around the Sun at around 30 km/sec, in its annual path, which takes a year to complete. The Solar System revolves around the Milky Way centre at around 230 km/sec. It takes around 225 million years to complete… Continue reading How fast is the Earth moving through space?
