Mysterious sounds heard all over the world have researchers completely stumped. They’ve been happening for quite some time, with the latest example coming from Pennsylvania, with multiple townships being affected by these mysterious sounds, feeling their vibration and waking them up in the middle of the night. It wasn’t long ago when residents in Alabama were left baffled when a loud boom resounded across much of the state.

Speaking to ABC 3340, Bill Cooke, head of NASA’s Meteoroid Environment Office, said that the Alabama boom could have been caused by a supersonic aircraft, a ground explosion, or a bolide – a large meteor that explodes in the atmosphere. The noise was picked up by the US Geological Survey, where data suggests that the boom wasn’t the result of an earthquake. The boom may have been caused by a military flight of a supersonic jet, although the US Air Force did not confirm it.

The day after the boom in Alabama, a similar noise was heard in Idaho. This year alone, similar noises have been reported 64 times this year, in locations including Michigan, Lapland, St Ives, Swansea and Yorkshire.

When the one in Alabama happened last year, the Birmingham National Weather Service tweeted,

On November 17, 2017 a boom in Lapland was caused by a fireball from a falling meteor. Footage showed a bright light in the sky over Inari in Finland – but the flash was so intense it was also seen in Russia’s Kola Peninsula and in northern Norway. Stargazers reported seeing the sky ‘light up like day’ for a few seconds alongside a loud noise as the space rock plummeted towards Earth.

These are just a few of multiple examples. To see a list of mysterious booms that happened in 2017, you can click here and scroll towards the end of the article. They’ve happened on many occasions and nobody really knows what they are.

Below is some mainstream media coverage of the most recent episode in Pennsylvania from secureteam10a youtube channel that covers this type of strange phenomena.
