Troll alert. Space and time are elements of spacetime, they are an integrated whole, a fact first pointed out by Einstein's math teacher Minkowski. When Einstein first read what Minkowski had written, he said, “Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore.”

Only later, after learning tensor calculus and beginning work on GR, did Einstein understand what Minkowski was going on about. But in those days people were interested only in getting it right, not posturing as right even when they're wrong.

Troll alert.

Please don't resort to name-calling, regardless of the language used by fellow commenters.

It's not name-calling. This person really is a troll, a term with an unambiguous definition: http://www.urbandictionary.com/define.php?term=troll . He tries so hard to earn the label that it seems unjust to withhold it.

In the days of Usenet, before there was an Internet, this sort of language was regarded as neutral and informative -- it's not abusive when it's accurate. But the Politically Correct movement in social media is seeing a revival, such that even accurate use of these terms is regarded as counterproductive.

In the Usenet era, some individuals would strive to earn the label, and applying it would save people a lot of time trying to engage in constructive conversations with people who were manifestly unable to rise to the occasion.

Bottom line -- it's possible to take PC to a pointless extreme. And I'm hardly the first to make this point.

If they're a troll, don't feed them. That goes back to Usenet as well. There's never a reason on HN to be uncivil.

> There's never a reason on HN to be uncivil.

Fair enough, but this begs the question of what constitutes incivility. If present trends continue, telling someone that they're wrong will be regarded as uncivil behavior. To avoid censure it will only be possible to assert that they've posted "alternative facts."

I happen to agree that incivility represents a real problem in social media, and we've seen many sites abandon their discussion groups because of uncivil posts and people. But I think the argument can be made that definitions have changed as well as behavior.

> That goes back to Usenet as well.

Not really. Having posted there for many years, I can tell you from direct experience that the perceived threshold of incivility has changed completely. One need only review posts from that era to see the point that definitions and standards have changed.

But this is now, and an argument about what was once acceptable doesn't seem particularly persuasive even to me, especially now that we have an embodiment of incivility running the country.

Just to keep score: You called me a troll, because I called someone an a-hole, for calling me a liar. That's what just happened. What a totally PC Snowflake Soap-Opera. Of course that's based on the assumption that the 'Sock Puppet' burner accounts aren't BOTH YOURS to begin with. hahahahaha. omfg that would be hilarious. In case it doesn't even matter, i'm using my REAL identity.

Nice dissertation on 2+2=4. I've known relativity for 30years. The point i was making (as i'm sure you genuinely DO actually know, despite pretending once again to need to correct me), is that even physics professors in the middle of physics lectures will say "space" or "time", depending on context. Learn the fact that English and all languages have syntactical nuances. Oh,and thanks for the warning that you are a Troll, but I don't mind. I'm biting the hook. Nothing thrills me more than debating physics. Thus the 30yrs.

You aren't debating physics.
