Black hole mystery finds an original solution

“BLACK HOLE MYSTERY” says the cover of a recent Scientific American. “The first supermassive black holes formed earlier than seems possible.” The author is Yale astrophysicist Priyamvada Natarajan. “What are scientists missing?” the cover asks. Maybe the answer is: A grasp of quantum space and the topology of twist. It’s a massive problem in more […]

How does Planck-scale physics work?

Planck-scale physics is more than a hundred years old. Physics is starting to take it seriously. This is great because we can hope for exciting new science and technology to drive a new economy. Planck scale is the incredibly tiny scale at which physics actually happens. It is the scale at which space no longer […]

Until recently our cosmic neighborhood was growing faster than the speed of light. Now it’s run into a roadblock.

“From a physical point of view everything that is outside our neighborhood is pure extrapolation.” – Willem de Sitter (1932) Physics is coming up against two fundamental limits: It can never observe the biggest and the smallest things that it needs to study. Some seem satisfied this is the end of our search for ultimate […]

How Does Teleporting Happen?

Teleporting may be an everyday event throughout the universe. Physicists experimentally demonstrated it some time ago. Recently they set a new distance record: six kilometers. Sounds like progress. Problem is that nobody knows: How does it work? ‘Beam us up, Scotty’ are the magic words that Star Trek fans know make it happen. In Captain […]
