Prof. Brad Skow speaks with WCVB-TV’s Chronicle about the concept of time and the “block universe” theory of time, which states that time does not pass by but is instead part of the larger fabric of the universe. “The future is a place just like Australia,” says Skow. “Australia is far away spatially and the future is also far away temporally.”
Prof. Rosalind Williams reviews James Gleick’s new book about the history of time travel for The Washington Post. Prof. Williams writes that Gleick “gathers an engaging cast of characters who wrote these stories or otherwise explored the possibilities of time travel.”
In a new study, Prof. Alan Guth shows how time might move backwards as well as forwards, reports Joshua Sokol for New Scientist. “We call it the two-headed arrow of time,” Guth says. “Because the laws of physics are invariant, we see exactly the same thing in the other direction.”
In a piece published by The Huffington Post about a new time travel simulation, Lee Billings highlights Professor Seth Lloyd’s work developing a new model for a “closed timelike curve,” or a loop that could be traveled back into time.
