Oh-My-God particle

 The Oh-My-God particle was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, U.S. At that time it was the highest-energy cosmic ray that had ever been observed.Although higher energy cosmic rays have been detected since then, this particle's energy was unexpected, and called into question theories of that era about the origin and propagation of cosmic rays.


The Oh-My-God particle's energy was estimated as (3.2±0.9)×1020 eV, or 51 J. This is 20 million times more energetic than the highest energy measured in electromagnetic radiation emitted by an extragalactic object.It had 1020(100 quintillion) times the photon energy of visible light, equivalent to a 140 grams (5 oz) baseball travelling at about 26 m/s (94 km/h; 58 mph).


Assuming it was a proton, this particle traveled at 99.99999999999999999999951% of the speed of light, its Lorentz factor was 3.2×1011 and its rapidity was 27.1. At this speed, if a photon were travelling with the particle, it would take over 215,000 years for the photon to gain a 1 cm lead as seen from the Earth's reference frame.

Floaters look like small specks, dots, circles, lines or cobwebs in your field of vision. While they seem to be in front of your eye, they are floating inside. Floaters are tiny clumps of gel or cells inside the vitreous that fills your eye. What you see are the shadows these clumps cast on your retina.  pc: @sourtruth

The Backwards Moon🌒🌒

The Backwards Moon🌒🌒 Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet's rotation. It is the only large moon in the Solar System to do this. ... Some believe that it condensed this way from the original material of the early solar system. 👉 Follow @map_of_science_ for more scientific fact and information.
