Time Travel in Einsteins Universe: The Physical Possibilities of Travel Through Time by J. Richard Gott III

In this fascinating book, the renowned astrophysicist J. Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

Einstein's Theory of General Relativity

We all travel forwards through time. But what does it actually mean? Has your Maps app ever saved you from getting hopelessly lost? Yep- us too! This technology works by allowing your phone to communicate with satellites that orbit 20, km above Earth and plot your current location. In his theory of general relativity, Einstein says that if an object has a large enough mass it can physically bend space and time.

In many universes, typically those on TV shows or in movies, time travel is not much more difficult than driving downtown in any major city during rush hour. Sure, the traffic can get gnarly, but no law of physics prevents you from reaching your destination eventually. Yet time travel does not necessarily violate the laws of physics. Such paths are known as closed timelike curves. Headlines and summaries of the latest Science News articles, delivered Tuesdays and Thursdays. Besides, even if such pathways did exist, building a ship to traverse them would cost more than all the DeLoreans and all other transportation vehicles ever made.

November 9, He was right. But he was also right that asking whether time travel is possible is a "very serious question" that can still be approached scientifically. Arguing that our current understanding cannot rule it out, Hawking, it seems, was cautiously optimistic. So where does this leave us? We cannot build a time machine today, but could we in the future? Let's start with our everyday experience.

What happens when extreme gravity pierces the fabric of space-time? The big unsolved problem of modern physics is reconciling its two pillars: general relativity and quantum mechanics. Quantum gravity would unite them. Yet years on, it still raises many questions — and physicists continue to look for something better.

In , Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time. Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity. Two objects exert a force of attraction on one another known as "gravity.

Part of the Einstein exhibition. In , at age 21, Einstein had his university diploma and was eager to begin his career as a physicist. He struggled to find work, however. After two years of searching, Einstein took a relatively low-level job at the patent office in Bern, Switzerland. Glad for the income and steady work reviewing patent applications--and still able to think about physics after hours—Einstein settled into a comfortable routine. Each day he walked to work through the streets of Bern, a city famous for its medieval architecture and beautiful clock towers.
