Doesn't that defeat the purpose~?

checked as well, hun

In order to perform interferometry, either light has to be sent through a tunnel, or the phase of the light must be recorded.

When performing interferometry across the world, obviously the tunnel isn't an option.
And recording the phase of the light isn't possible for frequencies in the terahertz, as far as I know.

So, how about reducing the frequency?
Although frequency is a completely unalterable property of waves, it can be modulated with a new frequency by having it interfere with a different frequency.
The produced frequency can be as low as you like, and as long as you know the phase of one wave the phase of the produced wave will tell you the phase of the other wave.
So if you can produce a wave of a known phase, and that wave has a close enough frequency to the observed wave that you can record the phase of the produced wave, you know the phase of the observed wave.

If you can produce a wave of 10^8 Hz while knowing its phase, and it interferes with light of 10^14 Hz, then the resulting variation in amplitude is 10^6 Hz which would certainly be much more plausible to record the amplitude of.

Is there a scientific reason this isn't done?

In one dimension, static equillibrium is defined by one equation: ΣF=0
In two dimensions, there are three: ΣFx=0, ΣFy=0, ΣM=0.
In three dimensions, there are six: ΣF=0, ΣM=0, where each of these is a vector equation 2ith three components.
So
1 => 1
2 => 3
3 => 6

How many equations in four dimensions?

I'm an junior in getting my BS of Mech E, so yeah you pretty much say im a mathematician/scientist.

I want to hear what this means to you, in your own words.

Does anyone here have any seemingly persistent family traits, carried down one or more of their lineages?
According to simple theory, genetic traits should rapidly diffuse, and for a trait to be present at the same (or even a growing) strength in every generation of a family is incredibly unlikely.
However, if one applies the idea of like attracts like, and also takes into account that people with good genetics can be extremely selective about who they reproduce with, the possibility arises of people with uncommon traits always finding people with those same traits to reproduce with.

Evidence of people reproducing based on uncommon traits would be having such traits present on both sides of your family, and scaleable traits failing to get weaker with every generation because people with those the same traits end up attracting someone with similar/complimentary traits underlying.
