How Many Stars Are In The Known Universe?


By Robert Drake (

~~~~~~Exclusive for THE STRANGE~~~~~


Our Galaxy has about 200 billion stars according to Michio Kaku's book "Hyperspace". Some estimate there are as many as 200 billion galaxies in this universe.


Our Galaxy is called the Milky Way Galaxy. Some estimate there are 250 billion stars in our galaxy. The diameter of our galaxy is about 100,000 light years. A light year is equal to 5,878,500,000,000 miles or about 5,900 trillion miles. Thus, the diameter of our galaxy is about 590,000,000 trillion miles.


Galaxies normally form groups or clusters. If we include the 11 Milky Way satellite galaxies as part of the Milky Way Galaxy, our Local Group of galaxies consists of about 20 galaxies. Some believe that our Local Group may some day be "eaten" by the Virgo cluster. This would be something similar but on a larger scale to the Sagittarius Galaxy, which is about 1,000 light years across, that is apparently being pulled apart by the gravitational force of our Milky Way Galaxy.


When we consider that our Local Group only contains 20 galaxies, it is small potatoes compared to the known universe of some 200 billion galaxies.


To add to the complexities, there is what is called Dark Matter. Scientists do not know what Dark Matter consists of, yet over 50% of the matter in this universe is made of Dark Matter.


We really don't know if there are other universes beyond our own universe. We also don't know if there are inter-dimensional universes within our universe.


Life forms do not need to be limited to being made of matter as we know it. For example, there could be plasma and/or dark matter beings. Perhaps there are 100s if not 1,000s of species of intelligent beings. Some of these may bear no resemblance to humans much less reptiles or insects.


The key point is not whether there are intelligent beings outside of those on the planet, but rather is there a means that intelligent beings can travel faster than light in order for inter-stellar travel to be effective? I sense the faster than light barrier will be exceeded by this planet's technology in about 20 years.


Some people consider the possibility of a few ET confederations made of humans, reptilians, greys, etc. here within this Local Group. Based upon the data shown above, I would consider these conclusions rather limited if we consider potential life forms beyond this Local Group of Galaxies. Based upon the vast distances between the Local Groups, space travel would need to nearly reach the speed of infinity for it to be effective between these groups. I sense this barrier could also be breached.


If there are intelligent beings in space and if faster than light travel can be accomplished, I suspect that not even the most technologically advanced ET Confederation understands the total picture. Because there are some 200 billion galaxies in our known universe, with our Local Group only having 20 galaxies, the odds are that the most technologically advanced ET Civilizations would not be included in our Local Group.
