But I don't know how he managed what he did...If they were aliens from this universe, and we are comfortable with the concept that in any given universe the law of physics are constant, then no.
In your example, torque is the name we give to rotational force. The units (newton-meters) are chosen because they give an apt way to measure and quantify rotational force in terms we can easily understand. We could assign a completely new unit to rotational force, but it would still be appropriate to use units of (force x extent - [the terminology is important here as it helps distinguish torque from work (force x distance)]). The alien may have a separate unit for torque, but it would still be equally valid to use the alien's terms for extent and force.
Now, if the aliens are from a different universe, all bets are off.
Not sure this is true. The only definitions I can find for universe only a apply to this one. Others may share nothing in common with this one. Not matter, space, energy or time.Hmmm. By definition, there can be at most one universe. Science fiction and science fantasy to the contrary notwithstanding.
You may like to take a look at this, R!f@@:Aliens ?? Ya ..right....Keep dreamin.
There ain't any aliens that we could find. I am not saying they are not out there.
Did you really went to the moon ?
