Dark energy is cosmology’s biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is.
This program, Ending the Epidemic: Science Advances on AIDS, brings together leading researchers on the forefront of scientific efforts to understand and attack the virus that causes AIDS. Moderator Richard …
What if we could peer into a brain and see guilt or innocence? Brain scanning technology is trying to break its way into the courtroom, but can we—and should we—determine criminal fate based on high-tech images of the brain?
The nature of time is an age-old conundrum for physicists, philosophers, biologists and theologians. The Newtonian picture of time—a kind of cosmic clock that ticks off time in a manner that applies identically to everyone and everything—tightly aligns with our experience. But with special and general relativity, Einstein showed the fallacy inherent in experience.
Stuff happens. The weather forecast says it’s sunny, but you just got drenched. You got a flu shot—but you’re sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds?
Consciousness is a terrible curse. Or so says a character in screenwriter/director Charlie Kaufman’s Being John Malkovich. Part theater of the absurd and part neuroscience fiction, the Oscar-winning filmmaker’s work captures the splintering between what we perceive and what we feel as our brains grapple with multiple layers of reality.
Mathematical mysteries have challenged humanity’s most powerful thinkers and inspired passionate, lifelong obsessions in search of answers. From the strangeness of prime numbers and the nature of infinity, to the turbulent flow of fluids and the geometry of hyperspace, mathematics is our most potent tool for revealing immutable truths.
The mysteries of dark matter and dark energy may be evidence that we don’t fully understand the force of gravity. But when it comes to a force that has been studied mathematically and probed observationally for hundreds of years, what do we still need to learn?
