Astronomers have discovered what is now the smallest known star in the galaxy, in a system roughly 600 light-years from Earth. Part of a trinary star system, the smaller of the pair, EBLM J0555-57Ab, is estimated to only be 8 percent of the mass of our own Sun, in a compact package no bigger than Saturn.

This itty-bitty sun may represent the smallest size that a star can be: to sustain the hydrogen fusion process that provides a star’s energy, the gases within must be brought to a high pressure and temperature, meaning that there needs to be enough mass present in the star to provide these conditions.

A growing number of scientists are starting to seriously consider the possibility that we are living in a Matrix-like computer simulation, including influential physicists such as Dr. Michio Kaku. And some are actively looking for scientific clues as to whether or not this is a constructed reality, as a team of researchers from the University of Bonn in Germany are doing, looking for patterns in simulations of the mechanics of the universe, and seeing if those patterns also hold true to "real life".
