What Is Quantum Reality? Does Time Exist? Will Dying Black Holes Explode in Firewalls?
Major scientific discoveries can disrupt the traditional order, leaving scientists adrift in concepts that resist familiar intuitions and beliefs. Of the new ideas that emerge, some will be wrong and some will be right. Honest and open scientific controversy helps disentangle one from the other. Eventually, one side of a debate grows in strength and finds confirmation in experiments, while the other atrophies. But both sides of a controversy contribute to the breakthrough of actual discovery – when the utterly abstract barges into the realm of the concrete. This series celebrates that passionate spirit of scientific debate. For the Pioneer Works series Scientific Controversies, we take a look at profound topics at the frontier of physics that have inspired unresolved debates.
