Paradox-free time travel is 'logically' possible, say physicists

Grandfathers, take heart. You'll survive the paradox that's been gunning for you since the 1930s.

  • For a century, the specter of paradoxes has loomed over physics theories and science fiction scripts.
  • A University of Queensland undergraduate and his supervisor ran the numbers and found paradox-free time travel to be mathematically consistent.
  • But the practical hurdles to time travel vastly out distance the mathematical ones.

    • Alexey Turchin and Maxim Chernyakov, researchers belonging to the transhumanism movement, wrote a paper outlining the main ways technology might someday make resurrection possible.
    • The methods are highly speculative, ranging from cryonics to digital reconstruction of individual personalities.
    • Surveys suggest most people would not choose to live forever if given the option.

    Time: Do the past, present, and future exist all at once?

    Does time exist? Here's what the debate is all about.

    • Everything we do as living organisms is dependent, in some capacity, on time. The concept is so complex that scientists still argue whether it exists or if it is an illusion.
    • In this video, astrophysicist Michelle Thaller, science educator Bill Nye, author James Gleick, and neuroscientist Dean Buonomano discuss how the human brain perceives of the passage of time, the idea in theoretical physics of time as a fourth dimension, and the theory that space and time are interwoven.
    • Thaller illustrates Einstein's theory of relativity, Buonomano outlines eternalism, and all the experts touch on issues of perception, definition, and experience.
