Just as Dudley was in front of the door, a new Big Bang happened.
It happened inside of him, the gas leaving his digestive tract accelerated his body to Mach speed in a fraction of a microsecond, Vernon and Petunia couldn't have seen it coming.
Dudley's deadly outburst lifted the house out of its foundation and gave it the ability to fly on its own. Alongside the Dursley residence, Harry and Hedwig were also accelerating to near light speed and the entirety of them flew to Hawaii. Through the enormous force that came out of Dudley, the British Isles were pushed into Europe, causing the northern part of France and the Benelux countries to be crushed beneath its mass. Furthermore, a new Mountain chain through Germany and Scandinavia formed, while the highest mountain in the world ascended in the Alps.
Ireland was sent off towards America, causing a massive deluge to be sent off towards South America and it was entirely flooded, save the highest peaks of the Andes. Ireland crashed into the northwestern United States, yet the speed did not stop at impact and it drifted further, emptying the Great Lakes and completely obliterating the Midwest, until it was halted by the Rocky Mountains of Vancouver and Montana. Petunia and Vernon were caught by the flying Dudley and he carried them until the curvature of the earth caught their projectile-like form, but it did not end and the unstoppable force pushed them quickly and easily through the mantle and further into the molten core.
The Planet itself lost the precious, billions of years old and well kept balance and went on a crash curse with Neptune. Nobody survived this event and the only ever found remnant of humanity and the life on earth was a lonely satellite drifting through deep space.
THE END
A/N: This was the first ending I wrote for the story, but decided to go with the other one. Recently found it and decided to throw it out for fun, I hope you enjoy!
I happen to not own Harry Potter, just thought you might want to know.
