Wow. this thread shows how bad reading comprehension really is these days.
The original article says nothing about an impact at soddom and gohmorah, but that the effect of an impact elswhere.
The clay tablet is a 700bc COPY of an earlier work by a sumerian astronomer.
The asteroid was a kilometer long, not a mile long.
Any comparison between the dino killer, and this object as to the size of the effect are not valid, for two reasons IMPACT VELOCITY, and object
The dino killer was travelling at a tremendous speed, closer to that of a comet than a near earth object.
The average comet has an impact velocity of 51 kilometers per second while the impact velocity of an near earth asteroid is only 17 kps.
The energy released can be estimated by the equation E=1/2*mass*velocity^2
To illustrate for a mass of 1 an object traveling 17 meters/sec will have an energy of 289j whereas an object travelling at 51 m/sec will have an
energy of 2601j thats nine times the energy.
Then you have to take density of the object into effect the dino killer was likely very dense metallic rocky object.
While an impact like tunguska was caused by a carbonaceous object, made up of hydorcarbons and dust, a dirt clod basically.
So you could have an object of a lage size and lower velocity that would not be a planet killer.
What is interesting is the time scale of the theroized impact event, it falls in line with the time line for the previously mentioned possible impact
that caused burckle crater and subsequent tsunami deposit chevrons on both sides of the indian ocean basin.
It also falls inline with the sumerian tales of the flood, which state they were caused by devastating useasonal summer rainfall in sumeria.
What is also interesting is that I have read a paper by another astronomer that has placed the possible burckle object into a gropu of objects that
share an orbit, a asteroid swarm so to speak, whose known orbital periods, when back calculated put them into position for possible impacts in the
right time frame for this discussion.
They also are appropriately positioned for the possible impactor on the north american continent 12k years ago.
And there is geolocical evidence for an impact event at kofels.
