As for micro black holes, I'm more inclined to believe it was an exploding UFO then that, it really looks like it was a small comet or asteroid.

Evidence points to the Tunguska impactor being part of the Beta Taurid meteor stream - fragments of Comet Encke (2P) which underwent a major split several thousand years ago. The Beta Taurids are a daytime stream, peaking on June 30 - we re-encounter the stream later in the year as the Taurids in October/November.
I remember seeing this on TV about a great fear that if it was from this stream, then we would have no idea of seeing it coming whatsoever on the daylit side of earth in late June.

The Americans are convinced it was an asteroid - based on deposits taken from trees. The Russians are convinced it was a comet, and the Italians have a team investigating the lake to see if they can identify possible debris from the progenitor.
Just imagine if it had hit a few hours earlier then St. Petersburg would have been obliterated. :roll:

If the lake was formed by the comet, then exploring the lake bed sediments will surely have tell tale materials in it, it looks like a simple one to resolve.
I've wondered about that also. There is a perfectly circular lake in the Slieve Bloom mountains called Clear Lake. TAS went up on 'expedition' there in 1994 prior to our big sponsored walk. It was purported that a meteor, seen over the mountains in the late 1800's, might have caused the lake. We took samples of the water and sediment, and sent them to UCG and UCD. Nothing conclsive came back, but put the chances of it being an impact crater further down the list.
Maybe something like that was done in Russia, but because of that damned Iron Curtain of theirs...

But IF (as is thought) that the meteor OR comet exploded 5 miles above the earth and the whole event was caused by the shockwave of said meteor or comet, surely there would not be very much if ANY material left to find to prove either theory .
As seems to be the case cuz the arguement for both still continue today.
