Special Relativity Of Framing

When I saw the link to this article I though, "hmm, sounds link an interesting physics article." Sorry, no. It's a badly framed article about cosmic rays and their aging-like effects.

Was Einstein Wrong about Space Travel? | Science Blog: "Consider a pair of brothers, identical twins. One gets a job as an astronaut and rockets into deep space. The other stays on Earth. When the traveling twin returns home, he discovers he's younger than his brother.

This is Einstein's Twin Paradox, and although it sounds strange, it is absolutely true. The theory of relativity tells us that the faster you travel through space, the slower you travel through time. Rocketing to Alpha Centauri -- warp 9, please -- is a good way to stay young.

Or is it?"

OK, please, if you're going to do popular science writing, get it right. Einstein wasn't wrong. You, article writer person, are. Einstein is talking about the effects of speed. You're talking about the effects of cosmic rays. So, putting on my scifi hat, I simply raise shields, no more cosmic rays, but still special relativity effects when traveling at sub-light, but very fast speeds.

Now, if I'm traveling faster than light (see the article below), then we can also forget about relativity.

These 2 things have nothing to do with one another. The writer thought that they were being clever, but frankly, they're just confusing people that might not understand.
