Impossible Mission To Captcha Infinitesimal Moment

(alternately titled: tick tock runneth amuck) 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 *****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 *****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.
