A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
- Princeton physicist Hong Qin creates an AI algorithm that can predict planetary orbits.
- The scientist partially based his work on the hypothesis which believes reality is a simulation.
- The algorithm is being adapted to predict behavior of plasma and can be used on other natural phenomena.

A unique star system where exoplanets orbit their star backwards located by researchers.
- Astrophysicists find a very rare system with two exoplanets orbiting their star backwards.
- The star system K2-290 is 897 light years away.
- In our Solar System, all the planets revolve in the same direction as the rotation of the Sun.
A protoplanetary disc was twisted almost 180° before planet formation.

A new study found the possible reason why some dwarf galaxies appear to not have dark matter.
- A new paper presents a possible reason for why some dwarf galaxies appear to be missing dark matter.
- The researchers at the University of California, Riverside ran cosmological simulations to find the answers.
- They discovered some galaxies were stripped of dark matter through extreme tidal loss.

Radar astronomy is nothing new, but a new transmitter may give us unprecedented image resolution.
- A new, high-resolution image of the moon has been produced using radar astronomy.
- Objects as small as five meters wide are clearly visible.
- The image was part of a proof of concept test — a larger transmitter may soon be built.
