Measuring Distances in the Universe With Fast Radio Bursts


Astronomers still aren't entirely sure what causes fast radio bursts, which can briefly release a galaxy's worth of energy. However, they might have figured out how to use them to measure distances in the Universe. In a new paper, astronomers propose that fast radio bursts could be detected as they're magnified by stellar microlenses. With about 30 microlensing events, they should be able to measure cosmic distances precisely.
