One of the great ironies of science is that, in the search of truth, we spend all of our efforts trying to prove ourselves wrong. We design a model, assume it’s true, and test it against the data. When the data doesn’t fit, we toss it. And to be considered serious scientists, we need to try our hardest to prove ourselves wrong.
But what qualifies as “wrong?” Just how inconsistent does our data need to be before we toss the model? Part of the answer to this question comes from statistics, and a number called the P-value.
Welcome back! This is the last part of the series on relativity. Today we’ll talk about how gravity effects time and space. You might want to look at last week’s post before you read this one. It explains the basics of gravity in General Relativity. Go back to the Theory of Relativity for Kids if you want to start at the very beginning.
Welcome to part 3 of my series on the theory of relativity for kids. Start here if you missed the intro. Up until now, we’ve been talking about something called special relativity. Today, we’ll start talking about general relativity, a theory that explains the bizarre ways that gravity works.

Last week I wrote an intro to the theory of relativity for kids (and curious adults). I’ll be continuing this over the next several weeks. Click the link above to see the intro, or read ahead to learn more.

So you want to understand the theory of relativity, and you’re a kid? No problem. Let’s get started.
(If you’re a parent looking for some activities to help teach your kid, consider ordering Albert Einstein and Relativity for Kids: His Life and Ideas with 21 Activities and Thought Experiments. And if you’re an adult who just wants to understand relativity, there’s no shame in reading on.)

I relayed the scientific consensus on global warming as presented by the IPCC in an effort to introduce some much…
Despite dispute in the media, the scientific consensus is almost unanimous: the world is getting warmer as a result of human activity. But the scientific consensus is so clouded by politics that it’s very difficult for the average person to figure out what’s going on. I’m sick and tired of this, so what follows is a (hopefully) refreshing taste of dryness on the subject. No opinions, just the scientific consensus.
