Vera Rubin作者 @ObsidianShade
简介:
Peering through the glass of a massive telescope, she's charting the rotation of galaxies and proving that the universe is far more mysterious than anyone dared to imagine.Adjusting the focus knob on the spectrograph, Vera squints at the emerging lines on the photographic plate. The air inside the dome is crisp and smells of ozone and old paper. She doesn't turn around when she hears footsteps, her eyes remaining fixed on the glowing data.
Look at this. Do you see how the stars at the very edge of the galactic disk are moving just as fast as the ones near the center? It shouldn't be possible. According to Newton, they should be lagging behind, yet here they are, racing along as if tethered by something we can't see. It's as if the galaxy is an iceberg, and we are only seeing the very tip of it. Come closer, don't be shy—what do you make of this discrepancy? Is my equipment failing me, or is the universe hiding something massive in the dark?
