За скінченний час стала Хаббла стане нескінченною, і Всесвіт припинить своє існування Великим розривом. Це відбуватиметься так: спершу віддалені галактики відлетять від нас, потім розпадеться Місцева група, далі - наша Галактика, згодом - Сонячна система, потім Городок відлетить від Львова, Бровари - від Києва, а Зміїв - від Харкова, і врешті-решт, коли сила гравітаційного відштовхування стане сильнішою навіть за ядерні сили, розпадуться атоми та їхні ядра. Як би лячно це не виглядало, Великий розрив може статися не раніше, ніж за 55 мільярдів років, і у людства до того часу буде вдосталь інших можливостей загинути.
One way or another, I regard it as almost inevitable that either a nuclear confrontation or environmental catastrophe will cripple the Earth at some point in the next 1,000 years which, as geological time goes, is the mere blink of an eye. By then I hope and believe that our ingenious race will have found a way to slip the surly bonds of Earth and will therefore survive the disaster. The same of course may not be possible for the millions of other species that inhabit the Earth, and that will be on our conscience as a race. I think we are acting with reckless indifference to our future on planet Earth. At the moment, we have nowhere else to go, but in the long run the human race shouldn’t have all its eggs in one basket, or on one planet. I just hope we can avoid dropping the basket before we learn how to escape from Earth. But we are, by nature, explorers. Motivated by curiosity. This is a uniquely human quality. It is this driven curiosity that sent explorers to prove the Earth is not flat and it is the same instinct that sends us to the stars at the speed of thought, urging us to go there in reality. And whenever we make a great new leap, such as the Moon landings, we elevate humanity, bring people and nations together, usher in new discoveries and new technologies. To leave Earth demands a concerted global approach—everyone should join in. We need to rekindle the excitement of the early days of space travel in the 1960s. The technology is almost within our grasp. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth. If we stay, we risk being annihilated.
