> Why haven’t I heard about this before? It's probably just part of the "Earth's hum", which is waves. (Don't confuse this with the world wide paranormal hum people claim to hear) You probably should have learned of the hum at school, if you did, you'd have probably forgotten. As a 10 year old you'd either find it amazing and think of it forever or just forget. It would be interesting to rank it on the importance lev…

> (Don't confuse this with the world wide paranormal hum people claim to hear) Taking this sort of random swipe at at people who experience this is kind of rude. Even though it's pretty much confirmed it's not a real audio signal coming from outside of a person's body, there isn't quite enough evidence it isn't a real auditory sensation for these people (instead of psychological or "paranormal" issue).

This is ridiculous. Neither environmental hums nor hallucinations or tinnitus or other psychological sources are paranormal.

I'm fine dismissing out of hand paranormal hums and paranormal phenomena generally. You don't appear to even be in this group and yet you feel personally attacked?

The same effects that cause a tone when blowing across a bottle rim might cause a vibration like this when an ocean current moves over a deep trench.

It's called a Helmholtz Resonator fyi

This is internet; the place where people go to exercise their right to feel offended. Welcome!

I read the quoted part as the whole class of people with this auditory issue being binned as truth-is-out-there nutjobs, and decided to offer a bit of perspective. It was probably an overreaction on my part.

Also thanks for actually using the word seismologist instead of just calling them generic "scientists". Browsing through this website, it looks like Discover Magazine is a little bit more qualitative than the usual pop-science fluff sites. According to Wikipedia it was a 1980 Time Magazine spin-off that featured more in-depth reporting on scientific topics, but still aimed at a general audience and even had a column…

I had a subscription to Discover a number of years ago. I'm sad to see that they've started dumbing things down.

Same. I've not normally been interested in medicine, but I'd always read their Vital Signs section. It was almost always guaranteed to be captivating, even if the rest of the articles for the month weren't all that interesting.

But to be honest, that downward trend has been going on across all major publications for decades.

Why is north "up"?

Because some people hundreds and thousands of years ago drew it like that on maps, and people kept doing it that way for cross-compatibility reasons, and now it's a convention.

And the best part is that it depends on culture. In ancient Hebrew, east was venerated for a variety of reasons and was given the distinction as "up" (although I'm not sure that distinction really maps to our concept of up).

>>" It is very close to 0 degrees latitude, 0 degrees longitude." The 0 latitude could be relevant, but that the 0 longitude is in there is more an historical accident. The shape of the African continent is also interesting there.

I think the 0 longitude most likely is accidental. Yet, here is another thing to think about: Zero longitude is the longitude of Greenwich, i.e. London, a significant city through the ages. Cities and towns, especially ones with old age, aren't positioned randomly but in geographical suitable locations: valleys, rivers, coast, etc. Since the position of London is not random, the 0 longitude isn't totally random as we…

Just saying that software bugs tend to show up here. If the pulse was localized by cross-correlating data from lots of different stations worldwide, it could potentially be some kind of numerical artifact.

Perhaps because the sun comes up in the East (at that latitude at least)

I would imagine so, yes. Hence the cultural implications of "beginning" or "origin" since the sun was no doubt viewed as the locus of life.

One of the interesting implications is how they view the past as east and the future as west (or conversely, the past as in front of you and the future as behind you). I'm not precisely sure I yet understand why this is, but I wonder if it's a matter of visibility? e.g., we can "see" the past but not the future.
