The heat death of the universe is coming for us, but we don’t know when. The cosmos is constantly expanding, and the speed of that inflation is measured by a value called the Hubble constant, According to the newscientist.
The Hubble Constant is the unit of measurement used to describe the expansion of the universe. The cosmos has been getting bigger since the Big Bang kick-started the growth about 13.82 billion years ago. The universe, in fact, is getting faster in its acceleration as it gets bigger.
We have two ways to determine this rate, and they have always returned different values, leaving researchers at an impasse. A new study of the stars we use to measure the distance to other galaxies has deepened the divide, Leah Crane wrote in the news. One way we search for the Hubble constant is to start at the beginning. We can look at the cosmic microwave background (CMB) – a relic of the first light to cross the cosmos after the big bang – and see how fast the universe was expanding back then.
