29. New Testing Methods
In 2015, a new and more advanced method was tested. This method looked at the gravitational waves, which are also known as the “ripples” in spacetime.
These ripples were studied by the amount of time they were taking to reach earth, and how fast they went through the cosmos.
Unfortunately, there is still a bit of a gap between these findings and the well-known Hubble’s Law findings, so working towards filling this gap will be necessary.
