Stephen Hawking: "There is no God. No one directs the universe."
Hawking, who died in March, answers questions like "Is there a God?" and "Is time travel possible?" in his final book, which is available today.
- Hawking's final book is geared toward a popular audience.
- Each of the book's 10 chapters is posed as a question, such as "How did it all begin?"
- Hawking claims there is no God, time travel could be possible and intelligent aliens exist.
The final book from Stephen Hawking, the late theoretical physicist and cosmologist, was released Tuesday under the title Brief Answers to the Big Questions.
Hawking, who lived most of his life with the neurodegenerative disorder amyotrophic lateral sclerosis (ALS), was still working on the book when he died in March. The work was completed by his family and publishers, who filled in the gaps by drawing on an "enormous personal archive" of essays, interviews and articles from Hawking's half-century career.
Brief Answers to the Big Questions is divided into 10 chapters, each of which is posed as a question: "What is inside a black hole?", "How did it all begin?" and "Is there a God?" Hawking's answer to the God question is a resounding "no."
"There is no God. No one directs the universe," he writes. "For centuries, it was believed that disabled people like me were living under a curse that was inflicted by God. I prefer to think that everything can be explained another way, by the laws of nature."
This sentiment, by the way, is far clearer than what Hawking famously wrote in his 1988 bestseller A Brief History of Time: "If we discover a complete theory, it would be the ultimate triumph of human reason – for then we should know the mind of God."
Hawking touched upon the existence of alien life.
"There are forms of intelligent life out there," he wrote, adding, "we need to be wary of answering back until we have developed a bit further."
He also argued that traveling back in time can't be ruled out, artificial intelligence might someday outsmart humans and "within the next hundred years we will be able to travel to anywhere in the Solar System."

Hawking's final book probably won't have a big impact in the scientific world. Still, as Matin Durrani writes for Physics World, there's a good chance the book will strike a chord with a popular audience.
"Brief Answers to the Big Questions will appeal to school students, undergraduates and non-scientists with an appetite for the grand challenges in physics. Those who are more familiar with cosmology, relativity and astronomy will not find much that is new, although it is always interesting to see Hawking's take on affairs. In essence, this book – especially the final chapter "How do we shape the future?" – will stand as Hawking's manifesto. Optimistic, upbeat and visionary, it sees science – and scientific understanding – as vital for the future of humanity."
At a book launch event on Monday in London, organizers played some remarks from Hawking lamenting the changing ways in which scientists are received in the culture.
"With Brexit and Trump now exerting new forces in relation to immigration and the development of education, we are witnessing a global revolt against experts, and that includes scientists," Hawking said.

The team caught a glimpse of a process that takes 18,000,000,000,000,000,000,000 years.
- In Italy, a team of scientists is using a highly sophisticated detector to hunt for dark matter.
- The team observed an ultra-rare particle interaction that reveals the half-life of a xenon-124 atom to be 18 sextillion years.
- The half-life of a process is how long it takes for half of the radioactive nuclei present in a sample to decay.
Humans are particularly prone to shiver when a group does or thinks the same thing at the same time.
A few years ago, I proposed that the feeling of cold in one's spine, while for example watching a film or listening to music, corresponds to an event when our vital need for cognition is satisfied.
Certain colors are globally linked to certain feelings, the study reveals.
- Color psychology is often used in marketing to alter your perception of products and services.
- Various studies and experiments across multiple years have given us more insight into the link between personality and color.

Certain colors are globally ties to certain emotions, the study reveals.

They were also asked to specify the intensity with which they associated the color term with the emotion.</p><p><strong>Certain colors are globally linked to certain emotions, the study reveals.</strong></p><p>The results of this study showed a few definite correlations between colors and emotions throughout the globe. Red, for example, is the only color that is strongly associated with both negative (anger) and positive (love) feelings.
