I love reading about different peoples experiences with this unexplainable stuff.
I've skimmed through this thread, and there is
nothing posted in it that is not explainable,
unless you don't bother looking for an
explanation.
Some of the descriptions posted are consistent with aircraft in the distance (eg TheCuriousOne's description above my post), whilst others could
easily be satellites, and even possibly meteors in some cases.
Someone mentioned "speeding up and slowing down", and "zigzagging" motion was mentioned a few times, but it's actually
not uncommon for an
object to
appear to do these things even if it's not, which is due to the way our brains interpret what we are seeing - under certain
circumstances information from our eyes can be
misinterpreted. The result is an optical illusion.
The main problem is that when we look up at an object/light in the sky, there are usually very few visual cues, and without visual cues the
likely-hood of an optical illusion being experienced increases dramatically.
For example, when a bright satellite (or it could be
any light/object - the effect is the same) is seen in a reasonably light polluted sky (ie
the vast majority of stars are not visible), because there are few (if any) reference stars (visual cues) visible close to the satellite, an observers
brain will struggle to accurately judge the speed of the satellite, which can result in the satellite appearing to speed up or slow down.
This same set of circumstances is also responsible for the apparent "zigzagging" motion that
many people (including myself) sometimes observe
with satellites (and other lights in the sky), and the resulting illusion is known as the "autokinetic effect".
The only way to tell
for sure if an object in the sky is moving erratically, is to capture footage of it or photograph it, and then analyze the
footage/photograph to determine if there is any erratic motion.
See the thread I recently posted which covers most of the descriptions mentioned here:
Flashes and Star-like objects that move strangely in the sky explained
To sum up, yes people see things that look strange in the sky, but there is much more evidence that this is due to people making bad witnesses (due to
our flawed perception) rather than it being due to "unexplainable" phenomena.
To put it bluntly - get some proof (footage) before claiming that something unexplainable is going on rather than just your eyes playing tricks on
you, which is the most likely explanation in cases where erratic motion is observed. Otherwise it's just contaminating a forum that is supposed to be
reserved for truly inexplicable phenomena.
