Blog 3 Dark Energy by Mark Kingston Levin, PhD
What is Dark Energy?
It is the energy that is causing the Universe to expand at an accelerating rate. If the energy were converted to mass, (using Einstein famous equation E = mc2 that would make up about 70 percent of the Universe). Dark Matter 25 percent and all we can see plus the stars and planets we cannot because they are two far away equals about 5 percent.
How can we learn about the Universe? Astronomers and other scientists like Edward Hubble first pointed out that other galaxies exist in the billions. He also used the red shift to predict most these galaxies were moving away from us, leading to the big bang theory. The further they were from Earth the faster they moved away from Earth. Although that is true most times, there are exceptions. For example, Andromeda is expected to collide with our Milky Way galaxy in about 4 billion years. The answer for human survival is to move to one or more long life nearby solar systems that are longer life and have habitable planets. Long before that happens, the oceans will boiloff and earth will no longer be habitable.
In astronomy, the standard candle refers to a type 1a supernova, which can be about as bright as an entire galaxy but only lasts for a about week. Astronomers and other scientists now have a tool to measure distance with some accuracy because these type 1a supernova are always the same brightness. Is the data from the Humble telescope accurate enough to solve Dark Energy? No explanation has yet, come forward from the data.
Dr. Levin, in his novel 30th Century: Escape through his leading lady, Jennifer puts forth an interesting and original idea. That is that Black Holes create space. If true that idea could expand the universe and explains Dark Energy. It is not quite that simple, we need to no more about black holes and the next two space telescopes planned is James Webb and HDST shown below may give us more answers or more questions.
The space telescopes, James Webb to be launch in 2018 and the HDST maybe launch after 2030 but before 2040. In the scheme of things, it will not be a long wait before we get to look at planets for the signs of Life and its biology. The James Webb will focus on the infrared and will not be a replacement in the visible and near infrared for Hubble. We must wait until 2030s. Stay tune for next blog about what could have caused the BIG BANG?

Dr. Levin was born and grew up in Vermont with many winters spent in Florida as a child. As a teenager he wrote poetry, served as a lifeguard and played football. He currently enjoys sailing, exploring underwater caves, snorkeling, writing science fiction and other pursuits. After working on the Apollo and Mars projects, he returned to school to study under Nobel Laureate Paul Dirac, obtaining his PhD in 2.5 years. Dr. Levin founded two companies and served the science policy apparatus in President Ford’s administration. He has been published over 44 times in scientific literature and was awarded over 32 US patents. The science fiction writer is now emerging with his first work, a trilogy entitled 30th Century. The first award-winning book, 30th Century: Escape, is currently available on Amazon. Book two in the series, 30th Century: Revived, should be released before the end of April 2018.
