Scientists May Be One Step Closer to Figuring Out How Fast the Universe is Expanding

Scientists have long been aware of the universe's expansion. However, there is much debate among scientists on just how fast the universe is expanding. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist The universe is big, and it continues to get bigger every day. The hotly debated topic of how quickly space itself is expanding is vital to understanding the actual scale, size, and age of our universe and the speed at which the universe is growing is called the Hubble Constant. The Hubble Constant, named after pioneering astronomer and University of Chicago alum Edwin Hubble, underpins everything in the universe—from when the Big Bang happened to how much dark matter exists. It helps scientists sketch out a theory of the history and structure of the universe. Edwin Hubble was the first to observe that objects astronomers once thought were spiral nebulae were actually entire galaxies outside our Milky Way, and that space was much, much bigger than we thought. Because many of these other galaxies had wavelengths that had been so stretched out, the light they emitted was tinted red, and astronomers realized they were heading away from us. Establishing that the universe was expanding was the easy part, but pinning down the rate it’s doing so was a bit tougher.
