Title text:

Unstoppable force-carrying particles can’t interact with immovable matter by definition.

Transcript:

[An arrow pointing to the right and a trapezoid are labeled as ‘Unstoppable Force’ and ‘Immovable Object’ respectively.]
[The arrow is shown as entering the trapezoid from the left and the part of it in said trapezoid is coloured gray.]
[The arrow is shown as leaving the trapezoid to the right and is coloured black.]
[Caption below the panel:] I don’t see why people find this scenario to be tricky.

        That just moves the problem, what happens if I put a piece of paper between them? Unless they don’t interact with anything they still face the same problem.

          I mean we have these in the universe, one example of an unstoppable force is neutrinos. These tiny particles certainly seem to contain a whole lot of energy, moving close to the speed of light. But just try to stop one.
