So, many probably remember this from 2-3 months ago, someone goes back in time and changes something, and another user tells what happened, then they go back in time. Based off the "Butterfly Effect" Theory, that changing even the smallest thing in the past, can dramatically alter the future. So I'll start:
I go back in time to 1941 and I tell the Japanese are about to invade Pearl Harbor (and they believe me).
Korea has been florishing for the past few decades. They are now the leading power in the world bent on making everyone see as they do; a perfect democracy. I go back in time and create a civil war in Korea so that it separates in half and is no longer as strong.
I go into the future take the transformtion gun that I made, bring it back to 2011 and am about to hand it over to some scientists to get it out faster, but something happened. On my way to the place, I accidentally shoot myself with the bra setting on near a Victoria's Secret. I am blown in there and bought by a hot girl. She wears me for the rest of my life. Wait... that means that I don't make the Transformation Gun... which means..... Paradox?
Your great-great-great-great-grandmother marries someone else, and when people found out it was you that murdered him, you become a worldwide fugitive, similar to Soap and Price from CoD: Modern Warfare 2.
I go back in time and I cancel the Manhattan Project (be more creative than "Japan takes over the US")
Racial segregation is still not an issue in the states...however, the Ku Klux Klan represents MLK as their prime target, and have countless attempts of assassination in the future, one becoming successful shortly before he dies of old age.
I go back in time to the time of the Revolutionary War, I give the patriots several modern-day weapons, including plans and materials for making more, to use against the British.
I come forward from the future back to when this comments were made and stop this butterfy effect from the main source by convincing the TehAlphaGamer to not create this Forums and to stop the time machines I destroy them before made creating an epic paradox hopefully stopping this monstronsity from ever happening
