Stephen Hawking on “The Ultimate Migration” -Will the Human Species Be Able to Adapt to Life Beyond Earth?

 

Human Exoplanet Migration

 

Before his death in 2018, Stephen Hawking predicted that the world’s mounting population will consume enough energy to render the world a “ball of fire” within 600 years. Speaking via video in 2018 at Beijing’s Tencent WE Summit, Hawking declared that humans must “boldly go where no one has gone before” if they wish to survive another million years.

Our Solar System’s Milky-Way Orbit 19 –Extinction by Dark-Matter Apocalypse?

 

Milky Way Galaxy Infrared

 

At present, our Solar System is in its twentieth orbit of the Milky Way near the inner edge of a spiral feature known as the Orion Arm or, less poetically, the Local Arm. The ghostly arms are not permanent features of a disc galaxy like the Milky Way. Rather, they are concentrations of gas and dust where stars form, produced by disturbances within the Milky Way, or on occasions by a jolt from outside, such as a supernova or the passage of the Solar System through one of the dusty gas clouds that congregate in spiral arms.

The Point of No Return -Scientists Compare Current Climate Change to Geologic Past

 

Antarctica Climate Change

 

“As we put more greenhouse gases into the atmosphere and temperatures rise, we are quickly rewinding the climate clock to climate states not seen in human history,” wrote acclaimed University of Wisconsin paleo-climatologist Jack Williams in an email to The Daily Galaxy. “We can expect that over the next few decades, climates will most resemble those of the warm Pliocene, roughly three million years ago, or perhaps even the hothouse Eocene, 50 million years ago.”

Snowball Earth Era –“Changes in Earth’s Orbit Enabled Emergence of Complex Life”

Snowball Earth

 

In the blink of a geological eye, nearly 600 million years ago, a massive ice age radically altered the planet’s climate, resulting in a “Snowball Earth,” also known as the Cryogenian Period, severely constricting the oxygen supply on the planet. Scientists at the University of Southampton have proposed that changes in Earth’s orbit may have allowed complex life to emerge and thrive during the most hostile climate episode the planet has ever experienced.
