I often find it difficult to match my space travel with my daily life. I don’t travel as fast as people living on the equator; they ride the earth’s rotation at 1,000 miles an hour, but I still feel the spin sometimes. We orbit the sun every year at 67,000 miles an hour, covering 92,960,000 miles. Our Solar System is part of the Milky Way galaxy, a 100-billion-star city that rotates with other galaxies. Astronomers thought we traveled with 3,000 other galaxies in the Virgo Supercluster, but now they think Virgo is only an appendage of the Laniakea Supercluster.
Laniakea is a Hawaii...
