Physics students examine superhero science: Could Superman really have reversed time?

  • Yes, i agree.

    Yes superman could have reversed time. Seven years of student-led research into superheroes between 2009-2016 suggests Superman could be the best-equipped superhero of all, with a number of abilities including the ‘Super Flare’ attack and possession of high density muscle tissue
    Wolverine, Thor and Mystique are also in the upper-tier of superheroes, having accelerated regenerative abilities, high energy output and being capable of gene manipulation

  • Apparently he could

    Superman flew backwards around the earth to bring Lois Lane back to life. Physics students have calculated that it's potentially possible for an object to fly backwards around Earth, and they've figured out the speed and mass it would need to actually "reverse" time. Also, they learned that there's a big potential for destruction, so it shouldn't be done.

  • Yes superman could have reversed time

    Seven years of student-led research into superheroes between 2009-2016 suggests Superman could be the best-equipped superhero of all, with a number of abilities including the ‘Super Flare’ attack and possession of high density muscle tissue
    Wolverine, Thor and Mystique are also in the upper-tier of superheroes, having accelerated regenerative abilities, high energy output and being capable of gene manipulation
    Black Bolt is likely the single most destructive superhero based on a high energy output capable of resulting in planetary annihilation
    Student calculations suggest the most ill-equipped superhero could be Batman, who would struggle to survive a landing after gliding due to the velocity of his movement
    Research from the University of Leicester has deemed Batman to be the “most ill-equipped” of the superheroes, claiming that the velocities Gotham City’s finest reaches when gliding through the air would be likely to kill him on landing.

    In a series of papers published over the last seven years in the Journal of Physics Special Topics and Journal of Interdisciplinary Science Topics, students at Leicester have examined the viability of a range of superhero characters. Superman, they have determined, would be “best equipped” to prevail among the contenders they have studied, which include the Flash, Thor and Iron Man.

    Looking at everything from the Man of Steel’s muscle tissue – his skin density “would have to be 296 g/cm3 to stop 50% of standard handgun bullets” – to how he reverses the polarity of the Earth’s spin (he increases his relativistic mass by 13.7m times by travelling close to the speed of light, they write), Superman is the “the number one candidate for ‘most powerful superhero’”.

  • Not possible in the way anyone is saying.

    How does changing motion change time? Moving the earth backward is not only is very dangerous and could have horrific effects on the earth. It wont change time. Time is not dependant on the earths motion, never has been, never will be. This arguement is invalid even if superman could move the earth backward

  • Would form a paradox.

    Any change you make in the past will not be an issue in the future so you never travel back. That may not make much seance so let me give an example.
    You want to stop the holocaust so you travel back in time from 2016 to kill Hitler in his crib in 1890 and succeed. The holocaust never happens so now in 2016, you have no reason to go back and kill Hitler. Seeing that you don't travel back, the holocaust still happens.
    If such a paradox can exist, it would mean two separate timelines. Problem is, the timeline where someone travels back never changes as the motive to travel back can not change or else void the time travel.

  • No Superman could not have reversed time!

    The second law of thermodynamics states that the total entropy of an isolated system always increases over time, or remains constant in ideal cases where the system is in a steady state or undergoing a reversible change. A corollary of this law is that time flows in one direction; its direction is unshakable.
