My theory about the strange sounds are due to changes in the earths magnetic field above those areas. If someone where to record the temperature in those areas at the time the sound is being made I wouldn't be surprised if there were noticeable changes in temperature and or wind. Can someone look further into this? I don't really have too much of an idea where to start.

That is a logical theory OP. however it has been suggested many times in the other 'sky sound' threads.

I love how everyone has an explanation of these sounds. There should be just one thread where all you experts can propose your theories, instead of creating a whole new thread.

/end rant

Although the sounds sounded in some videos like from inside a spaceship (and hell I have dreams of things or place that I see for real in the future and I had dream of green lights and ship in the air), those videos that had them could be fake ones. The ones that were probably true, I also considered to have been caused by Earth,.

Which is NOT good for those who don't want it. I personally am for a massive change of the continents and such drastic changes on this planet because people seem to have forgotten thinking about this planet, and need a good reminder.

All scientists of the Mayan calendar say that its previous periods ended at times of big changes. I hope such change finally comes in the upcoming years.

There is a constant 'sound' in the air where I live, its called urban/industrial murmur, or background rumble/hum. It never ceases, its always there, when local traffic slows in the middle of the night its more noticeable. This comes from air, rail, and highway traffic, 24-hour industry, sewer system, even transformers on telephone poles and street light switches, and basic home infrastructure.
