Is Buying a House One of Life's Most Stressful Events?
Anyone who has purchased a house, especially one which required you to move from your former residence, knows that few things feel more stressful.
What's the Latest?
Anyone who has purchased a house, especially one which required you to move from your former residence, knows that few things feel more stressful. But surprisingly, moving house doesn't fall on the list of life's forty most stressful events, at least according to the Social Readjustment Rating Scale, a sociological tool developed in the 1960s to measure the stress caused by different life events. On that scale, places one, two, and three went to the death of a loved one, divorce, and marital separation. Though having a large mortgage did come in at number 20, a change in living conditions at 28, and having a small mortgage placed as the 37th most stressful life event.
What's the Big Idea?
When it comes to our health, daily hassles and their subsequent stresses burden us more than catastrophic events because of their ability to wear us down over time. And on the list of daily American hassles, solving problems related to "property, investment, and taxes" comes in at number eight. The distinction between daily hassles and major life events is interesting to social scientists because of how we relate to them later in life. The daily hassles remain ever-present while our memories of life events change over time, often shifting to exclude those which we felt intensely but for a short period of time--such as moving house.

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.
