Today, cryptography has moved beyond the realm of dilettantes and soldiers to become a sophisticated scientific art—combining mathematics, physics, computer science, and electrical engineering. It not only protects messages, but it also safeguards our privacy. From email to banking transactions, modern cryptography is used everywhere.
Without dark matter and dark energy, the equations of physics don’t match what we observe in the cosmos. But what if it’s not the universe that needs extra ingredients—but the …
