Stephen Hawking is one of the most well-known scientists in this day and age. 

The British astrophysicist was recently featured in a movie a few years back which was highly acclaimed and allowed his name to appear and raise awareness about his theories among the general population, and not just the scientific community.

The movie features highlights of his life, especially highlighting the part where he was diagnosed with amyotrophic lateral sclerosis, an extremely rare degenerative neural disease that causes one to lose control of their own body. 

The 72-year-old scientist now moves around in a wheelchair and speaks to others through a keyboard and voice synthesizer. 

His extraordinary feat of achieving success even with this disease hindering him has inspired many around the world. 

However, Stephen Hawking's personal trials and tribulations are not the only things that got people to notice him. 

He is famed in the scientific community for his theory on black holes, and "Brief History of Time", his bestseller book that has caused him to be famous worldwide. 

Recently, Dr. Hawking was featured on Channel 4's "Live from Space: Lap of the Planet", a documentary and live series that shows real-time broadcasts from astronauts living on the International Space Station (ISS). 

On the live broadcast, Dr. Hawking claimed that in order to prevent the extinction of the human species, humankind has to colonize other planets. 

This is because Mother Earth is an "old world" with a finite number of resources that is being depleted too quickly because of overpopulation. 

He suggests humankind venture out into the never-ending cosmos, being the true generation that carries the name of "Space Age". 

He further added that this would be achieved when humankind will be able to live on the Moon, and then moving on to colonize Mars in the next 50 years.

This really sounds like something from a sci-fi movie, but what Dr. Hawking claims about our Earth not being able to sustain us is true. 

Fossil fuels are running out, our forests are being destroyed more and more, and our ozone layer is being depleted. 

Perhaps his solution is the one that will truly save us all at the very end, and is sustainable for thousands of years, ensuring the survival of our kind.
