So we can get ice-cream together, and listen to music, and travel across galaxies, only to have it end in slammed doors, heartbreak and loneliness?
",,", "It helps cosmologists to work out the rate at which galaxies are evolving.
With a sixteen-inch telescope, such as Evans uses, you begin to count not in stars but in galaxies.
" Zwicky also was the first to recognize that there wasn't nearly enough visible mass in the universe to hold galaxies together ,, and that there must be some other gravitational influence what we now call dark matter.
Nobody knows how many stars there are in the Milky Way estimates range from 100 billion or so to perhaps 400 billion 10004000 and the Milky Way is just one of 140 billion or so other galaxies, 1400, many of them even larger than ours.
Space cannot even properly be said to be expanding because, ,,, as the physicist and Nobel laureate Steven Weinberg notes, 、·: "solar systems and galaxies are not expanding, and space itself is not expanding.
It is enough to know that in a single cracking instant we were endowed with a universe that was vast ,,,--,, at least a hundred billion light-years across, 1000, according to the theory, but possibly any size up to infinite and perfectly arrayed for the creation of stars, galaxies, and other complex systems.
If you think of peering into the depths of the universe as like looking down from the hundredth floor of the Empire State Building 100 (with the hundredth floor representing now and street level representing the moment of the Big Bang), （100,）, at the time of Wilson and Penzias's discovery the most distant galaxies anyone had ever detected were on about the sixtieth floor, ,60, and the most distant things—quasars—were on about the twentieth.
" Normally only phenomena like supernovas -- catastrophic stellar explosions -- or entire galaxies are detectable at such vast distances.
Together, we can inspire galaxies of greatness for generations to come.
An Unexpected Day Since the moment galaxies fused together, The cosmos has been an invisible tempest!
From this reserve, you can see a duo of dwarf galaxies called the Magellanic clouds.
Some show us the explosive outbursts of dying suns, others the swirling masses of stars that make up the galaxies.
" Garth Illingworth, an astronomer at the University of California, Santa Cruz, and a veteran of the search for early galaxies, pointed out, however, that these stars were appearing far later in cosmic history than theory had predicted.
I'm sure there is a very wise and wonderful Being who designed, constructed, and operates this existence as we mortals know it: this universe with its galaxies and spiral nebulae, its stars and moons and planets and beautiful women, its trees and pearls and deep green moss—and its hopes and prayers for peace.
