The last asteroid collision with us was about 66 million years ago and that is thought to have killed the dinosaurs, and it will happen again. It is guaranteed by the laws of physics and probability.There are other problems like rising temperature, reduction of polar ice caps,deforestation overpopulation disease war human lack of water and decimation of animal species. If these problems keep growing human life would be unsustainable. The earth is becoming too small for us.

Will we survive on Earth? 

A black hole is a region where gravity is so strong that light cannot escape itself.A black hole has a boundary called the event horizon. It is where gravity is just strong enough to track light back and prevent it from escaping. Because nothing can travel faster than light, everything else will get dragged back also. It is much more likely to emit radiation. A mountain sized black hole would give of X-rays and gamma rays, at about 10 million megawatts, enough for world's electricity supply.

What is inside black hole?

Universe was spontaneously created out of nothing, according to the laws of science. The basic assumption of science is scientific determinism. We need three ingredeints to make universe<ul><li>Matter(stuff that has mass)</li><li>Energy</li><li>Space</li></ul>As we know the equation by remarkeable scientist Albert Einstien i.e. E=mc². Which says mass can be consider same as energy and vice versa.Ultimately we just need energy and space which was spontaneously invented in the event we call Big Bang.

How universe was created?

At the moment of Big Bang, an entire universe came into existence. So where did all this energy and space come from? For some, this is where God comes back into the picture.Postive side of things are energy & mass we see today. The negative side is spread throughout space. If the universe adds up to nothing, then you don't need a God to create it. If you like, you can say the laws are work of God, but that is more a definition of God than a proof of his existence.

Is there a God?

When you are faced with possibility of an early death, it makes you realise that there are lots of things you want to do before your life is over.

Not to leave planet Earth would be like castaways on the desert Island not trying to escape. We need to explore the solar system to find out where you humans could live.It won't solve any of our immediate problems on the planet Earth but it will give us new perspective on them and causes to look out words rather than inwards. The technology is almost within our grasp. It is time to explore other solar systems.Hopefully, it will unite to face the common challenge

Should we colonize space? 

The future will depend more on science & technology than any previous generation's has done. People need to know about science more than any before them because it is a part of their daily lives in an unprecedented way.We have to make sure this generation have not just the opportunity but the wish to engage fully with the study of science at an early level so that they can go on to fulfil their potential and create a better world.

How do we shape the future? 

Stephen Hawking was recognized as one of the greatest minds of our time and a figure of inspiration after defying his ALS diagnosis at age twenty-one. He is known for both his breakthroughs in theoretical physics as well as his ability to make complex concepts accessible for all, and was beloved for his mischievous sense of humor. At the time of his death, Hawking was working on a final project: a book compiling his answers to the "big" questions that he was so often posed--questions that ranged beyond his academic field. Within these pages, he provides his personal views on our biggest challenges as a human race, and where we, as a planet, are heading next. Each section will be introduced by a leading thinker offering his or her own insight into Professor Hawking's contribution to our understanding. The book will also feature a foreword from Academy Award winning actor Eddie Redmayne, who portrayed Hawking in the film The Theory of Everything, and an afterword by Hawking's daughter, Lucy Hawking, as well as personal photographs and additional archival material.

#1 NEW YORK TIMES BESTSELLER • The world-famous cosmologist and author of A Brief History of Time leaves us with his final thoughts on the biggest questions facing humankind. “Hawking’s parting gift to humanity . . . a book every thinking person worried about humanity’s future should read.”—NPR NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Forbes • The Guardian • Wired Stephen Hawking was the most renowned scientist since Einstein, known both for his groundbreaking work in physics and cosmology and for his mischievous sense of humor. He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live. In later life he could communicate only by using a few facial muscles, but he continued to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe’s greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet—including climate change, the threat of nuclear war, and the development of artificial intelligence—he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? ​​These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history. Featuring a foreword by Eddie Redmayne, who won an Oscar playing Stephen Hawking, an introduction by Nobel Laureate Kip Thorne, and an afterword from Hawking’s daughter, Lucy, Brief Answers to the Big Questions is a brilliant last message to the world. Praise for Brief Answers to the Big Questions “[Hawking is] a symbol of the soaring power of the human mind.”—The Washington Post “Hawking’s final message to readers . . . is a hopeful one.”—CNN “Brisk, lucid peeks into the future of science and of humanity.”—The Wall Street Journal “Hawking pulls no punches on subjects like machines taking over, the biggest threat to Earth, and the possibilities of intelligent life in space.”—Quartz “Effortlessly instructive, absorbing, up to the minute and—where it matters—witty.”—The Guardian “This beautiful little book is a fitting last twinkle from a new star in the firmament above.”—The Telegraph
