Wow, this is fascinating!
Our knowledge of the universe continues to change and grow as we get new information and discover novel ways of looking into our origins. In fact, our estimates of the age of the universe have gotten more precise over the years. But now, that estimate may be changing drastically — to almost double the previous number, if one physicist is right.
By the 1990s, scientists were estimating the universe was between 7 and 20 billion years old, which is a rather wide age range. However, in 1993, the Hubble Telescope was used to determine more precise distances between Earth and pulsating stars called cepheids. This research determined that the age of the universe was actually between 9 and 14 billion years old.However, as research continued on throughout the years, scientists developed another theory that the universe was between 13.7 or 13.
To create his hybrid model, Gupta combined several theories. One theory has already been debunked by many scientists and is called the”tired light” theory. The tired light theory says that red-shifting isn’t evidence a galaxy is moving away; a galaxy’s light only looks red because its light has traveled farther to get to us and has lost energy along the way.
