Do Black Holes Exist in Our Sub-Atomic World?

Black holes are spheres in space, and not the funnel shaped objects so often depicted in science fiction. They are defined by the speed of particles traveling towards their core. But they are controlled by the rate of change in that speed. The force of gravity can be expressed in kilometers per second per second. The creation and destruction of black holes can be understood in terms of a pendulum. When the inward force of a black hole is at its maximum, the pendulum is in mid-swing going in one direction. As a visible object approaches the mid-point, it reaches a speed that exceeds the speed of light and becomes a black hole. As it moves past that mid-point, it begins slowing down again. When its speed drops below that of the speed of light it becomes visible again and is no longer a black hole.  Do black holes exist in our sub-atomic world and, if so, how do we detect them?

3D printing might save your life one day. It's transforming medicine and health care.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.

  • Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
  • Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
  • Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.

Lama Rod Owens – the price of the ticket to freedom

An ordained Lama in a Tibetan Buddhist lineage, Lama Rod grew up a queer, black male within the black Christian church in the American south. Navigating all of these intersecting, evolving identities has led him to a life's work based on compassion for self and others.

For most of history, humans got smarter. That's now reversing.

We were gaining three IQ points per decade for many, many years. Now, that's going backward. Could this explain some of our choices lately?

There's a new study out of Norway that indicates our—well, technically, their—IQs are shrinking, to the tune of about seven IQ points per generation.

Lateral thinking: The reason you’ve heard of Nintendo and Marvel

Here's why generalists triumph over specialists in the new era of innovation.

Videos
  • Since the explosion of the knowledge economy in the 1990s, generalist inventors have been making larger and more important contributions than specialists.
  • One theory is that the rise of rapid communication technologies allowed the information created by specialists to be rapidly disseminated, meaning generalists can combine information across disciplines to invent something new.
  • Here, David Epstein explains how Nintendo's Game Boy was a case of "lateral thinking with withered technology." He also relays the findings of a fascinating study that found the common factor of success among comic book authors.
