Black hole collisions could help estimate how fast the universe is expanding
How fast is our universe expanding? The Hubble constant is one of the most critical numbers in cosmology because it tells us how fast the universe is expanding. There are different methods exist to measure this rate. However, determining this number’s accuracy is essential to understand better fundamental questions like…
