Supernova Explosion May Have Caused Mammoth Extinction

Came across this via Jan's LX90 pages

is that why there are less LX90's now. Theories are good, they are hard to disprove until science gets cleaver enough to do that.

Sorry Houghy science puts up an hypothesis. and if the evidence fits it becomes a theory and if furthur evidence modifies the the theory.then science adjusts the theory accordingly.
One example.
Newtons laws of motion , worked OK, problem with Mercury's orbit?
General Theory of Relativity from Einstein solved that one
Etc

Theories are just that, a basic hypothesis that works so far.Open for rational discussion WITH evidence!

Our research indicates that a 10-kilometer-wide comet, which may have been composed from the remnants of a supernova explosion, could have hit North America 13,000 years ago

Of course we should have realised, the extinction would have started there...

nice find 33 south I also heard the when betelgeuse goes supernova the blast may shear off our atmosphere when it hits.Thank goodness that wont be for a day or two
