Does anyone else notice that there have been more meteors hitting the earth lately. I remember there was another one that just hit last week
too. Wondering if this is just a start of something bigger.
This is quite a common misconception, and there is no evidence for it as I said
here.
Also further discussion
here.
Could very well be. The interplanetary defensive shield is down, and there are some strange things occurring throughout the entire Solar
System, which is even affecting the Earth, and seems to be happening because something massive is causing this, and whatever it is, it is affecting,
more and more the Solar System, so it must be getting closer, or the Solar System is getting closer to it.
Rubbish. What has the magnetosphere to do with incoming meteoroids? It protects us from charged particles, not rocks! If it did then why did we see
all the usual meteor showers (including outbursts and storms), as well as asteroids in the past decade, and previous to that?
Well, that day I visited my parents and while I was driving home at night I saw a real bright one which must have been fairly low in altitude
and I thought to myself - that's very cool.
Now, yesterday I'm riding my bike at 21:00 going home from work and as I enter the parking lot in front of the apartment building I see another one
over the building, again low altitude, bright light.
I mean what are the odds? Nothing for 3 decades and now 2 in three weeks.
We have a saying here... you wait hours for one bus, and then three come along all at once!
Bright meteors are actually quite common, especially at this time of year which is known for it's relatively high meteor activity rates. All you need
is a little luck to see some. Even if you are not specifically looking, it's usually just a matter of time till you see one one day when you happen
to be out.
I'd say the odds are pretty good
As for the apparent altitude, this can easily catch people out...
Meteors are only luminous at high altitude (except in the case of some extremely rare and large events), but they can also be seen from extremely long
distances due to their altitude and brightness. If you see a meteor close to the horizon in the sky, because Earth is curved, it looks lower than it
is.
Meteors can fool the unwary!
Here is a diagram I made to explain the concept:
Basically, our brains are hard-wired for estimating the distance, size, and speed of objects that are on the ground, where things are familiar, and we
have lots of visual cues in most cases.
However, when we see a bright light in the sky, there are few visual cues, and our brain misinterprets the few cues there are. Typically, a bright
light is interpreted by the brain as being closer to the observer than a dim light, so a bright meteor can fool us into thinking it is much closer
than it actually is. This works in much the same way as the
Moon illusion.
