Of course you can
Distance is only a distance you can measure
In UK they use inches , elsewhere foots, who knows some maybe use bigfoots and others meters, - etc............
I know some use small meters and other big meters
Did that make the point clear for you.,
While you did not appear to have a point in your response, it did remind me of the article,
List of humorous units of measurement, specifically of the
Smoot.
The smoot /ˈsmuːt/ is a nonstandard, humorous unit of length created as part of an MIT fraternity prank. It is named after Oliver R. Smoot, a fraternity pledge to Lambda Chi Alpha, who in October 1958 lay down repeatedly on the Harvard Bridge (between Boston and Cambridge, Massachusetts) so that his fraternity brothers could use his height to measure the length of the bridge.[1]
Now, here is one of the issues you're having trouble understanding. Using Oliver R. Smoot as a ruler, we can measure objects in Smoots. For the sake of discussion, let's say Oliver R. Smoot is traveling horizontally, parallel to the ground. He is hurtling towards the back seat of your car. Now your car being a high efficiency electric vehicle with a top speed of 30 kilometers per hour, does not have a back seat capable of accommodating a horizontal Oliver Smoot. Fortunately, he is traveling at relativistic speeds, so he is experiencing
Lorentz length contraction. As a result, Oliver Smoot, the living ruler, has contracted enough to fit inside the back seat of your car.
Now here's where things get weird.
Because the speed of light remains constant to all observers, your mother*, who is riding on Oliver Smoot during his high speed race to your car's back seat,
perceives the CAR as being in motion and sees the CAR contracting, making it even LESS likely Smoot and his rider will fit inside.
This creates a paradox.
You, believing in an absolute frame of reference, have no way of resolving this paradox. Since you've already conceded to the accuracy of the Lorentz equations, you also lack a way of AVOIDING this paradox. You have no means of safely stowing your mother and Oliver Smoot in the back seat of your car.
Fortunately,
Einstein has strapped on his math cape and is rushing to the rescue with additional frames of reference. Smoot will only fit inside the back seat of the car if both his head and feet are close enough together. In relativity, this distance is relative to each observer. The idea that the Smoot, both as a man, and a ruler, has a "real" or "absolute" length that will "really" come into play when he passes through the back seat is a fallacy. Smoot will perceive he's fit inside the car, but your mother will perceive that he scoots trough the comically small clown car back seat without his head and feet being inside at the same time.
Regardless,
I hope you drive a convertible. If not, your mother is getting knocked off Oliver Smoot at relativistic speeds, and while that'll be bad for both the car and your mother, I suspect your mother will fare worse.
*She's using him as a surf board. This is NOT a yo'mamma joke. Get your mind out of the gutter.
Extra Credit:
Use the
Lorentz transformations to tell how much of Smoot's body will extend outside the car from the viewpoint of Bjarne's mother. By the way, this is the EXACT sort of math Bjarne need to be doing if he wants to back up his claims about overthrowing special relativity.
Sadistic extra credit:
Do the calculation in Smoots, taking into account relativistic Smoot contraction for each frame of reference.
