No idea is too far fetched
Superheroes are real, The Doctor is real, Everyone has powers and are good. No Pollution, No Crime, Everyone is Immortal. Aliens exist and space is easily navigated and nowhere is to far. Oh and you can eat whatever you want and have no consequences.
Competent governments, huge progress in medical health, extended lifespan (someone at 60 would look 20 !!NOT IMMORTAL!!), increased interest in space travel and exploration worldwide, international high standard of education to all human beings, and a decent amount of interest in this education. No insanity (the bad kind). Increased attention span. Controllable metabolism (might not entirely understand this, pardon me). I don't want to remove free-will, however.
It is a endless space of earth/rock, water, ice, etcetera. It is a place of endless magic. Nothing is too weird or impossible to exist.
We have a land of Teddy bears, a land of fire and brimstone, a city of heroes, a nature filled world similar to the Avatar, a place where thoughts become reality and so much more.
There is space for everyone's fantasy. There is no true evil. It's the perfect place to exist.
The only bad thing in my Paradise is that the inhabitants long for pain, and limits so they decide to return to Earth and start another life again.
It would be a very jumbled mess, but a mess that would be organized within my sights. It would be an outer layer of cool dark colors and many grays in all of the dead and dying architecture. Underneath this world would be various pockets where colors and designs of all different kinds would seem to stretch on forever and ever. At anytime one could fall into the earth to reach one or the other layers, or they could simply lie in a river and be carried to any and all of their destinations.
A shining empire spanning multiple galaxies. Every city and town gleams in the light and shines at night. It's a utopia; no hunger, no war. Individual murders and crimes are quickly taken care of by legions of incorruptible enforcers. People can travel between planets and galaxies instantly, going through space travel only if they want to.
With me as the immortal emperor, of course, in a palace the size of the United States, standing proud in the very center of a planet-wide capital city.
A place where there are unlimited supplies of energy, there is no crime and evil is only in fiction. I have the ability to choose events that happen to others so that they can be full of happy fun sunshine, or when I'm in a bad mood I can cause widespread explosions... then reverse time to happy fun sunshine, and where these reality warping actions have no consequences. Music is all from the golden age of music (whatever you choose is the golden age) and improved medical industry, increasing the life spans. And lots of awesome sauce rainbows and awesomness with lots of nachos... nachos, everywhere, unlimited, where you can't get fat from it, and you can eat as many as I can, because I rarely eat junk food right now because I need my body to be in top condition, but nachos and lots of that would be soooo good... chocolate... chocolate... CHOOOCCCCOOOLLLAAAATTTTTTTE!!!!
Ahh, all of these worlds sound like horrible nightmares!
I like Earth and Mankind just the way it is, the fact we have different cultures, beliefs, races is what makes it all so great! The ability to be good or evil because we choose to be is what makes life worth living. The world needs evil for good to have any purpose or value.
The one on Supernatural, the TV show closely resembled to what I have in mind. People there are omnipotent, in a zone. Angels can take the power away from them, unplug them from their matrix. You can create things by thought, you have still maintain your regular form and your body clock: eat, sleep, drink. Or you can further develop your senses & mutate/evolve your body. People can reset themselves if they feel that they're lost in what they created, but maybe angels would use the reset button as their way of controlling the paradise.
Except if it's up to me, I would take away the angel component.
No, forget what I said. I'm still considering what my paradise would look like.
