No, you're just failing to read properly.

So, do some readingon the topic, and then you will understand. In the meantime, your lack of understanding doesn't change the fact that they can do this.

No, it's magical thinking to assume that science must be wrong because you know less than science does.

Given the science used, it would probably require magical thinking to hold that such a rock did not come from Mars.

The article says it left Mars 5 million years ago, which I think clears up both of your confusions.

Dibs on the Daryl Hannah bot.

Were they really nice cigarillos?

The problem is it can be unclear what is meant, or if something is being implied, when people start throwing in synonyms for no real reason. We're not all experts in the field, so when a summary throws in two terms - especially one which, in common usage, often implies a deliberate act (a detonation being the initiation of an explosion) - it's not unexpected that some people might find it confusing - even if all it does is raise suspicion that there might be some extra meaning for the differentiation that's escaping the reader.

It's bringing peace! Don't let it get away!

Break its legs!

This, sir, is a pavilion!

Well, maybe, but how would I know?

Oh god. And it's also Roko's Basilisk.

Why is it obvious?

Also, "don't" does not mean "never will."

For a particular definition of "aware" which seems rather circular, perhaps. Is a robot which can hear the name of an object being spoken, identify that object within it's visual field and pick it up with a robot hand aware of its surroundings? It's certainly capable of acting as if it is aware - and taken to an extreme, that's about all I can really say about other people.

I'm pretty sure 16:9 TV came first.

is the constants. If your process doubles in the measured quantity in 20 days then you have something that might be worth worrying about (assuming that it won't hit some other limit, so long as that limit isn't you), but if it doubles in 20 years you have some time to consider and prepare. Whenever I see talk about the singularity it seems like the growth people are talking about either has a very short doubling period (which it probably doesn't) or the growth is actually super-exponential (the doubling period itself is chchanging with time).

In either case, innumeracy will be our downfall before the singularity gets us.

X-Wings fly like planes in an atmosphere (come to think of it, they fly like planes in space too). They don't drop vertically and use the wings to steer. So, what's this got to do with X-Wings?
