You only nee... |

Interestingly, some animals only have half of their brain sleep at any given time, so that... |
My six year old daughter just asked what's beyond the edge of outer-space. I have no idea how to answer. Help? | A common misconception is that the universe is like a bubble or a balloon, this is due to the somewhat related analogies such as "The universe is expanding!" and so we think to ourselves, "Well, it must be expanding into something!" Or that we live in the world, which is in space, so "Space must be inside something!" I... |

What is the process they use to teach deafblind individuals, like Helen Keller, to read and write? | Well, first they have to learn how to communicate in some nontrivial way .

How come all these amazing breakthroughs I see in articals such as cancer treatments and battery advancements just seem to disappear and never to be heard from again | Because by adding the phrase 'amazing breakthrough' to an article, they've made you more likely to read it.

If California is running out of water, why do we continue to allow industrial agriculture to continue creating more and more water sucking farms to turn a profit and ship goods out of state? | It's not obvious to me that there is actually a trend of new farms sprouting up. The place to look would be [USDA statistics]. We don't have the numbers since the drought, ie the difference between 2014 and 2015 yet. If this is really going on, it doesn't look to me like part of a long-term trend: there were 77 900 far... |
How did racism begin if no one is born/inherently racist? | Humans are immensely tribal in nature. We are comfortable in our own groups and hostile to people from outside our groups, because we don't know if they can be trusted.
