Saving the City: Sans-Spandex

You’ve probably noticed that updates have been a bit sporadic lately.  This is likely to continue for a while.  The combination of new work hours and our busy time of year means that while we’re still going to shoot for Wednesdays, it might wind up being Thursdays sometimes.  On the plus side, we’re going to try to avoid our yearly November break, because we’re crazy people, and we don’t want to pause this very important arc.  We might do a short break once it wraps up.We’ll keep you updated, and thanks for your patience.

It's ok. I don't get it either.

Any questions or arguments should be directed to Laura, as she is the scientist responsible for the physics of superpowers. Now, if you want to discuss the effects of mechanical rules arbitration on the pseudo-medieval society of a typical D&D world, I’ll be right here. Hint: a wizard probably did it. (Hazel would totally get that joke.)

    “Whu…what?” LOL He’ll probably never figure it out.

    And Holy Cow Wall’o’text!

    Would you believe me if I said that understood all that without looking it up? XD

    My point being, don’t underestimate a speedster, and I’m glad to see this comic get it right! Major kudos from a physics amateur!

    • Chaos says:

      That made sense to me the first time I read it as well. For Mr. “Brick Shithouse” there, I suppose the concussion he probably got from that hit made things a bit difficult to sink in.

  3. David Johnston says:

    And…how does that explain how she ran in a straight line through him damaging only his bricks?

    • The Occupant says:

      What says she did?

    • xero says:

      oh thats easy Sword fight rules it only looks like that cause your eyes are to slow that she banked around him at the last second wich also cause him to get hit with her shock wave on top of what ever hit she did (likely a kab because if it was anything harder his head would be missing)

  4. mrtt says:

    So, did she have to learn the physics first before devising such a move or could she just do it due to her powers and the physics are just trivia for her?

  5. PaulW says:

    There’s a wonderful physics book out there by James Kakalios called The Physics of Superheroes and it’s a must-read if you’re into comics. When I saw this comic I immediately thought of that book.

    • The Occupant says:

      For the cheaper, the TV tropes page on Required Secondary powers also is an interesting read, though ‘ware links. The rabbit hole goes really, really to the power of really far down.

    If her feet hit the ground with relativistic velocity, why is the city still there?

    • TheGeek says:

      Just because she is moving a relativistic speeds forwards doesn’t necessarily mean that her feet are moving at that speed downwards when they hit the ground. When running at normal speeds your feet come to a complete stop for a fraction of a second when they hit the ground. That’s why running is a high impact exercise.

      • Stefan says:

        It might be possible to do as you say, but it needs an awful lot of coordination.
        She still needed to push herself of the ground forwards and upwards to accelerate to this velocity within one or two steps because friction allows us to walk around. And she had to decelerate within two steps. Her momentum had to go somewhere.

  7. BrogueTheRogue says:

    Don’t forget that you’re talking about relativistic mass. Yes, she’s moving extremely quickly. Yes, her relative mass is high. But it’s still lower than the *Earth*.

  8. Computant says:

    I find myself wondering how much momentum she can generate relative to the Earth though. Given that momentum is mass times velocity squared. Out-massing a guy wrapped in bricks probably only takes about 1000 lbs, call it X10 mass. This requires a speed of 298289 KM/Sec, (per Momentum is 1000*298289*298289 lbs*KM^2/Sec^2 (getting rid of the stupid english lbs at this step), 4*10^13. Earth’s mass is about 6*10^24 kg, so she changed the rotation of the earth by only sqrt(4/(6*10^11)) Km/s, 2.5mm per second.
    Given how close that speed is to “c,” the limit on further effects is actually how much mass she wants to take on. On the other hand, she is well over the speed of .9c, please refer to:

      University physics student here. I’m sorry to say that this explanation does not actually work.

      First of there is the problem of practicality. In order for any kind of relativistic effects to become relevant she would have to move so fast that the air molecules in front of her would be compressed to into a super dense and hot plasma way past the nuclear fusion threshold. The resulting explosion would completely wipe out the city if not crack apart the earth’s crust.

      However even leaving that aside it still wouldn’t work. In relativistic physics every observer moving at a constant velocity is equally valid. Thus while from the thug’s perspective the approaching Haze would indeed be super heavy and dense, from Haze’s perspective instead the approaching bricks would be super dense.
      Thus while relativistic effects would increase the damage applied to the bricks they would also increase the damage applied to her fist.

      So yeah, don’t try this at home kids.
