Summary:
- Astronomers have developed a new technique called "fast radio burst" (FRB) that can be used to measure the expansion of the universe. FRBs are brief, intense bursts of radio waves that come from distant galaxies.
- By analyzing the properties of FRBs, scientists can calculate the amount of matter between the source of the burst and the Earth, which provides information about the expansion of the universe over time.
- This new method is more accurate than previous techniques and could help scientists better understand the mysterious dark energy that is driving the accelerating expansion of the universe.
