“It turns out that sometimes the measurements and observations are problematic. Sometimes the theory has reached the end of its limits of its range of validity. But in all cases the scientific method is the same.”
From Neptune to Dark Matter
Something about Uranus did not make sense. Planet Mercury’s orbit was off kilter. Spiral blobs were spinning too fast. Most of the matter in the universe had not been detected.
To the rescue: science!
In this eposode of Ikonokast, Ethan Siegel brings us on a journy of scientific discovery through the Universe, from the inner solar system to the farthest reaches of space, and through time, from the very beginning (of time) to the invention of the Tardis.
Put on your headphones, start up the treadmill, and let Ethan convince you that Dark Matter is real, and discusses the narure of science.
