Don't start investing in flux capacitors just yet, though.
- The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time.
- Scientists used a quantum computer to show that time travel is theoretically possible by reverting a simulated particle from an entropic to a more orderly state.
- While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature.
Transport yourself to other worlds and states of mind.
- The early 20th century saw explosive growth for the science fiction genre.
- A wide range of these books would go on to become classics.

Proxima Centauri, our closest star, is more than 4 light years away. Reaching it under 10,000 years will be challenging; reaching it with living humans will be even harder.
- Eventually, humanity will want to travel to a new solar system to propagate the human race, explore, and maybe find signs of alien life.
- But our closest neighbor, Proxima Centauri, is so far away that current methods could take tens of thousands of years.
- How will we surmount this incredible distance and the other challenges associated with interstellar travel?
Some of them were surprisingly astute.
- In 1983, the Toronto Star asked science fiction writer Isaac Asimov to predict what the world would be like in 2019.
- His predictions about computerization were mostly accurate, though some of his forecasts about education and space utilization were overly optimistic.
- Asimov's predictions highlight just how difficult it is to predict the future of technology.
