Impossible mission to captcha infinitesimal moment

Ever since the advent of civilization
contrivances crafted to measure
days, weeks, months...
analytical “gifted” anonymous minds
wrought ever more sophisticated inventions
to divide existence into manageable units.

Now twenty first century Homo sapiens
technological atomic clock work mechanisms
markedly catapulted by quantum leaps
immense degrees of precision
extremely accurate types of devices
linkedin with state of the art electronics.

At this fleeting instant
(approximately 9:30 PM
August 23rd, 2020
ever so briefly wedged between
what elapsed and future events to arise)
impossible mission to isolate
that illusory present

not only cuz the herein now
flits away at light speed
(or greater - you're right quite dubious),
but also everywhere within
cosmic space/time continuum
infinite microscopic and
macroscopic events occur.

As an amateur thinker
I feel baffled when pondering
that crude convenient schema
whereby greater minds than mine
devised devices to measure passage of time.

Yours truly can barely articulate
his farfetched dumbfoundedness,
me merely a simple brute
(shortish but not so nasty),
whose permanently creased
furrowed brow courtesy
his scrutinizing noggin
encasing fifty plus shades of gray matter,

whereby one percent bonafide Neanderthal
deoxyribonucleic acid explains
atavistic predilection issuing primal grunting,
when foraging for small (lame) game,
cuz feeble minded twenty first century
run of the mill garden variety Homo sapiens
amuses himself (mentally)
toying with Einsteinian paradigm.

Though barely able to fathom
mind bending and boggling concepts
theoretically linkedin if an object
subjected to travel speed of light
(particularly an objet d'art - ha

think The Persistence of Memory
series of clock paintings by Salvador Dali)
mass becomes infinite
as does energy required to move entity.

Obviously the ability to wrap one's head
(or hands for that matter) around,
humongous (super sized) material essence
filling subsequent seconds, minutes, hours...
defies feasibility to grasp,
neither could ways nor means
allow, enable and provide
any semblance to hold (tangibly) as solid
something so abstract
as a singular moment, yes?

The above (ambiguously stated) thought exercise
equally as challenging to locate
beginning and/or ending point
upon Möbius strip.
