The Biggest Limitation on Human Thought: Certainty
I think that human beings are most limited in their tendency to pursue certainty and to think that answers are somehow absolute or even beneficial.
Jonathon Keats is a San Francisco-based experimental philosopher who has, over the years, sold real estate in the extra dimensions of space-time proposed by string theory (he sold a hundred and seventy-two extra-dimensional lots in the Bay Area in a single day); made an attempt to genetically engineer God (God turns out to be related to the cyanobacterium); and copyrighted his own mind (in order to get a seventy-year post-life extension.
Keats's bold experiments raise serious questions and put into practice his conviction that the world needs more "curious amateurs," willing to explore publicly whatever intrigues them, in defiance of a culture that increasingly forecloses on wonder and siloes knowledge into narrowly defined areas of expertise.
I think that human beings are most limited in their tendency to pursue certainty and to think that answers are somehow absolute or even beneficial. The degree to which we can go about the process of living as humans in increasingly interesting ways, in increasingly productive ways, is one in which we need to make our society operate, but once we get things working this can enslave us at a certain level. This can entrap us.
This can make us work according to other peoples' terms and they can put us on the track of trying to improve them in terms of finding better and better answers at the level of making things work more and more efficiently.
What we need is to step outside of that. We need to instead think about what those mechanisms are, what those technologies are, in which we can pursue questions that are bigger than those technologies, bigger than those routines, and therefore, lead to a more fulfilling life in which other opportunities for thinking and other opportunities for engaging our world come about every day.
Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
From time-traveling billiard balls to information-destroying black holes, the world's got plenty of puzzles that are hard to wrap your head around.
- While it's one of the best on Earth, the human brain has a lot of trouble accounting for certain problems.
- We've evolved to think of reality in a very specific way, but there are plenty of paradoxes out there to suggest that reality doesn't work quite the way we think it does.
- Considering these paradoxes is a great way to come to grips with how incomplete our understanding of the universe really is.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
