The Earth will turn into Mars and people will have developed advanced space technology allowing humans to travel far enough in order to find a planet able to sustain human life. Computers will be implemented in people's brain. Schooling will be data downloadable within the mind so instead of going to the university you'll just need to download the knowledge and store it in your brain.
Another human will be born. When he grow up, he will be smarter than Einstein. After some years of being discovered, he will do some experiments inside his Laboratory Room or something like that. Experimenting such as Flying Cars, Hoverboards and removal of Gravity in Earth. New gaming gear will be invented by another human. It will call Nervegear, based on Anime called "Sword Art Online". While this another Einstein experimenting, something came to his mind. He planned to make a spaceship, being bigger than NASA has. Spaceship that big as China's country, make a civilization there and explore the outer space. A doctor has been researching for a cure in Ebola Virus and all-type of Cancer.
I don't think that house size correlates with time.

I always liked the idea of a Matrix-style learning system. But if I think of all the other implications and apply such a system to our world instead of the Matrix universe, I fear the consequences. Something similar (chip in brain) is likely to happen, though, which is worrying. People already rely more and more on their stupid smartphones to do all the thinking; there are literally apps for everything, you don't need to think for yourself anymore.
removal of Gravity in Earth
You cannot 'remove' gravity. You can make anti-gravity chambers, or take a ticket for one of those "experience zero gravity" plane flights.
I think that we will have a flood all over the earth and we will go to a new earth
There is not enough water on Earth for a global flood.
People from the past express their feelings and thoughts through writing, painting, carving to perpetuate the moment.
The people at this time express their feelings and thoughts through social media, photography, video.
So, maybe it's all that our children will see, in our own museum in the future.
Quite tough.Just i'm telling my theories.Our earth will get a severe shortage of fuel and will have a very high temperature,Ultra-violet rays causing skin disease and all that,if scientists won't come up with a solution.On the brighter side,we will have teleportation,large houses,flying cars(for joy rides) and holographic computers and all those futuristic stuff.This won't happen without scientific development.Also the astronauts may find a new planet or aliens(like in raze series) and we get into battle with them.Fun awaits.So the future of the world will rest on the hands of Science.
