Whether you are a scientists discovering and inventing something or just an average guy without a university degree, you should know a few things that Stephen Hawking taught us.

The scientist dedicated his whole life to his career and found out plenty of stuff people had had no idea of.

Grand Unified Theory
A Brief History of Time written by Stephen Hawking is a great body of knowledge. Read this piece and you’ll find out what few of us are aware of. Theoretical physics has become different thanks to Hawking and his efforts to understand how subatomic and atomic particles behave. He proved that huge bodies like stars and planets behave in an absolutely different manner and that the same law cannot be applied to these two separate areas.

Some day we will need to leave our planet. Earth is overpopulated. It means that soon the climate change even more. Besides, humans will inevitably experience serious problems related to natural sources. Finding an extraterrestrial habitat seems to be the only way for us to survive in the future.
