The End of the Dinosaurs

AN: This fic. was inspired by my favourite scene in the film 'The Prince of Tennis – The Two Samurai: The First Game' . For those who don't know it, the relevant scene can easily be found by searching for 'Tezuka dinosaurs'.
I initially had this as a comic strip in my head, but I can't draw.


Sherlock was sitting in his usual chair, slowly rotating his gun in his hands contemplatively. John was watching a documentary which was explaining the various theories for the cause of dinosaur extinction. Normally John would not watch this sort of program in front of Sherlock, because he enjoyed disproving and nit-picking the theories.

When Mrs Hudson brought them their tea and Sherlock did not stop spinning his weapon, even for his usual curt thanks, John thought it would be safe to watch telly like a normal person without interruptions. Of course, he had forgotten that while Sherlock may not have the ability to export several pieces of information, his input had been trained to the point that he had noticed everything happening in the house and memorised it along with the theories being spouted from the TV.

Having processed the 10 cases his gun had given him inspiration to solve, he quickly lost interest in them, not even bothering to inform John, or the relevant parties. He called a belated thanks to his landlady, making John jump guiltily and suddenly switch off the TV.

"You do know that it is obvious why we don't have dinosaurs now, so why listen to this dribble?"

"Er, no, Sherlock, I don't know that it is obvious, please do enlighten me."

To most people the tone of John's voice would have suggested that John was just snapping back in annoyance, but as usual Sherlock took it straight and decided to reply.

"Well…"

It did not take long for him to decide on what to say, and John did not notice the pause, but in that time Sherlock thought through the whole history in order to simplify it for John's level of understanding.

Sometime in the early 21st Century an ace tennis player called Tezuka Kunimitsu, Captain of the Seigaku middle school tennis team, was playing in a match against Jean-Jacques Marseault of the Sakurafubiki tennis team. He was using his legendary move 'Tezuka Zone' which makes all balls hit by the opponent land on the sweet spot of his racket by predicting the opponent's actions, and adding the relevant spin needed.

For this game he had adjusted this move so that each hit increased the power, so when he hit the deciding shot it was so powerful that it seemed like each of those hits was represented by its own ball which converged on his racket. These balls, which were slightly out of synch with reality, were hit so fast that they broke the speed of light and travelled back in time and through space to the edge of our solar system, but got pulled back by the gravity of the sun and caught in the Earth's gravitational field. Moving extremely fast due to how far they had travelled while continually accelerating, they hit the Earth. Hard.

The resulting explosion burned any dinosaurs in the surrounding area, and caused a dust cloud to spread across the Earth. The dust prevented the dinosaurs breathing and stopped the sunlight from reaching Earth, killing the plants and cooling the earth. The giant lizards couldn't survive this new, cold climate nor evolve fast enough. This is how the dinosaurs died.

Sherlock glanced at his friend before speaking, but had to blink to correct his vision because John seemed to be sitting expectantly with a dunce hat on his head. Naturally John was doing neither of these things, so Sherlock decided to shorten his story a bit.

"Climate change…"
