The more I learn about the vastness of the universe, the deeper is my belief that we simply cannot be alone in the universe. Watch this animated flight through the universe made by Miguel Aragon of Johns Hopkins University with Mark Subbarao of the Adler Planetarium and Alex Szalay of Johns Hopkins. There are close to 400,000 galaxies in the animation, with images of the actual galaxies. The images and data came from the Sloan Digital Sky Survey (SDSS).
When you figure that our Milky Way galaxy contains an estimated 200-400 billion stars our own home galaxy is incredibly likely to harbor life. Astronomer Carl Sagan‘s once said, “The universe is a pretty big place. If it’s just us, it sure seems like an awful waste of space“
Sagan also continually described the universe’s potential for life being due to the “billions and billions” of planets out there. Though I’ve been watching the Mars Curiosity landing and the first pictures that have returned from that barren planet like this amazing 360 degree panorama, I do so with the knowing (and a tinge of sadness) that it’s highly unlikely I’ll ever leave this planet and explore another world.
Don’t even bother to do the math on 200 billion+ stars times 400,000 galaxies and the planets and the possibilities and…
…just watch the video. It’s cool:
