>you can't measure the real value of the length of this table, every time you measure it you get a random value that follows a gaussian around the real value, you can treat that number with statistics and calculate the interval where the real value has a 99% chance of being, but you never can measure the real value.
this is the dumbest thing that I learned in my physics major, I just measured my living room's table and every time I measured it I got 134.3cm
How is that not the real value?

Because your measurement is crude. Everyone knows that you're trolling by the way because the measurement problem is already taught in middle school physics.

Because you're discarding the estimate part 134.3(omitted part), for that kind of measures the end result only has systematic errors (humidity, temperature, measuring tape, mistakes).
Now if I ask you to measure that table with a precision of 10 micrometers then you'll see a distribution because any irregularity is large enough to alter your measurement.

So you're saying you have no error in your measurement, and have measured to infinite precision the table has a length of 134.3000000000000000000000000000000

Collapse happens at the level of the quantum waveform. So tenths of centimeters isn't going to cut it unless you get extremely lucky.
Also not sure if this is supposed to be a thought problem only but I'll go ahead and drag it into reality. If you measure a table you are going to change it slightly. So every measurement will be different. Using a tape measure for instance would wear away at the edge the tape it holding against. If you are using visual spectrum light then the photons are slowly chipping away at it as well.
I suppose if you had the table in a perfect vacuum chamber with no light at absolute zero temperature then it would remain the same. But then you couldn't measure it so from a quantum perspective it has an equal chance of existing and not existing

Thinks cm are primative.

This is just a normative statement. Given the odds of life occurring, the chances of measuring the table in any state are trivial. Luck is a meaningless distinction.

you dont need that many zeros anon
