And even if
the great multidimensional, string-theory main switch is shut off, it still
seems we only know about 4% of the known universe.
“Astronomers and physicists
are now grappling with evidence that suggests, even with the most powerful
telescopes, we can only observe four percent of the universe. The rest, they
posit, is dark matter and dark energy: " 'Dark,' cosmologists call it, in
what could go down in history as the ultimate semantic surrender. This is not
'dark' as in distant or invisible. This is not "dark" as in black holes
or deep space. This is 'dark' as in unknown for now, and possibly forever: 23
percent something mysterious that they call dark matter, 73 percent something
even more mysterious that they call dark energy. Which leaves only 4 percent
the stuff of us. As one theorist likes to say at public lectures, 'We're just a
bit of pollution.' Get rid of us and of everything else we've ever thought of
as the universe, and very little would change. 'We're completely irrelevant,'
he adds, cheerfully.
"The 'ultimate Copernican revolution,' as [astronomers] often call it, is taking place right now. It's happening in underground mines, where ultrasensitive detectors wait for the ping of a hypothetical particle that might already have arrived or might never come, and it's happening in ivory towers, where coffee-break conversations conjure multiverses out of espresso steam. It's happening at the South Pole, where telescopes monitor the relic radiation from the Big Bang; in Stockholm, where Nobelists have already begun to receive recognition for their encounters with the dark side; on the laptops of postdocs around the world, as they observe the realtime self-annihilations of stars, billions of light-years distant, from the comfort of a living room couch. It's happening in healthy collaborations and, the universe being the intrinsically Darwinian place it is, in career-threatening competitions.
"The astronomers who have found themselves leading this revolution didn't set out to do so. Like Galileo, they had no reason to expect that they would discover new phenomena. They weren't looking for dark matter. They weren't looking for dark energy. And when they found the evidence for dark matter and dark energy, they didn't believe it. But as more and better evidence accumulated, they and their peers reached a consensus that the universe we thought we knew, for as long as civilization had been looking at the night sky, is only a shadow of what's out there.” – Richard Panek: The 4 Percent Universe: Dark Matter, Dark Energy and the Race to Discover the Rest of Reality ( Houghton Mifflin Harcourt)
