The inescapable sounds of gravity. Rhythm songs of the 4-D space-time continuum. Anything round and rolling, especially metal coins and platters, glass and/or stone, that's allowed to spin, slow down, fall over, and settle, audibly rocking, oscillating, rolling and rotating downwardly, audibly accelerating ever-faster toward a quick stop on a hard surface.

THE EVERYDAY SOUND and SIGHT of 4-D ACCELERATION

(Is The Audio-Visual music & rhythm of Gravity)

A tabled or floored coin, dinner plate or serving tray on an axially spinnning roll, slowing down to a coil of orbitally circling around its own accelerating drum roll, finally and abruptly settling down to a quick-stop, in the making of a gravitationally resounding, perfectly spiral shaped nest. Physically rolling and sounding out a shrinking spiral while roundly resonating the rhythmically accelerating part. (What?) The same harmonious polka may be harkened in a characteristically accelerating rocking motion, from any number of utensils, tools or spherical objects, rocking (to & fro) on solid hard kitchen sink or floored surfaces. The commonplace sight and sound of that which is adamently pontificated as 'immeasurable', 'invisible', 'non-mathematically inaccessible, and 'unimaginable' (What?).

The song of an errant hubcap settling down on the asphalt all by its rolling and rotating self. Disassociated from the crashed Volkswagen it originated from - stuffed entirely beneath the inferno-enveloped 18 wheeler that rests on top of the pan-caked Volks beneath it.
Taking their epicurean places on the menu at THE ROAD KILL CAFE:
Perished thence, while concentrating intensely on not thinking about 4-D pachyderms. The avidly overstuffed People's Waggen ('Seig!), missing a wayward hubcap, musically and metallically wobbling down to a final halt on the crowded, rubbernecking, Marin county roadway ('Don't be afraid of daddy's driving!').
As though the now thickly gathered, conceptually dominant, starry eyed Big Bang gangers, knew and understood it all along.
( The free-way & autoban song of a liberated hubcap ).

Background theme from THE DAY AFTER, still playing on the charred, Geiger counter gagging, V.W. factory-FM radio, tuned to KBAY : In the air! Everywhere! Segueing to YOU DECORATED MY LIFE? Of course in stereo over a Princess phone. Naturally in & out of a NUCLEAR FREE ZONE.
Where (By and by; sooner or later) everything in present tense, continuously and collectively arrives from the past. Squared.

The sound, shape - and measurable sight - of materially manifest gravity. An everyday, globally ubiquitous occurrence. (You dropped something?) The reputedly 'immeasurable, unimaginable' 4-D space-time continuum.
Heat flows downhill; ever smaller.
Whereas, events flow uphill; ever larger.
Entropic universal heat death is not as a conceptual dogma and/or social obsession, meaningfully derived from the 2nd Law Of Thermodynamics. Any more than the 4-D space-time continuum can be excluded as the explanation for a steady state theory and the long withheld improvement over the incumbent, 4th dimension slaying big bang gangers. (Super strings, various hypothetically popular things, tacheyons, gravitons, flavored mesons, parthenons, leprechans, glueons, put-ons and take offs...)
The greatest - most auspicious lexicographers in the history of physical and astronomical science. Sine qua non.


A Disinformational Time Of The Signs:
'Time is a hallucination purveyed by the inventors of space.' - A (popularly deluded) bumpersticker mentality.

Actually: terrestrial time standards are based on astronomical motions of the planet(s) around the sun. A planetary year equals its completion of a 360 degree arc - round trip - about the sun (Which, itself is bound toward Vega). A month of 30 days is 1/12th of a year. A week is 1/4th of that month. A day is 1/7th of that week. An hour is 1/24th of a day. A minute is 1/60th of an hour. A second is 1/60th of a minute.
Therefore, a second of time, for example is also 18 1/2 miles of space: traveled by the earth in its annual orbit around the sun.
Sums up the bumper-stickered inspired hallucination. Its about time.
Non-Absolute Relativistic 4-D space-time. What it is:
Time, furthermore, in 4 dimensions, is shorter and faster in smaller, past (microcosmic) spaces, and slower (dilated) in future (macrocosmic) larger spaces; when compared to present time at any given moment of an observer in the eternal present: exactly between small fast space and large slow space. A square mile is not the same spatial size, when compared with itself; from the present: relative to (smaller, more dense) past or (larger, less dense) future 4-D expanding space.

Neither therefore, is 60 miles per hour (or 186,282 m.p.s.) always the same speed. Or a year, month, week, day, hour - or a second, always the same comparative duration.

Proving that the value of time varies with the value of space it occurs in.

Refer relativistic time dilation. Slow time (Macrocosmic 'weak forces') occurring in relatively larger spaces; fast time (Microcosmically 'strong forces') occurring in relatively smaller and larger (earlier and later) spaces. The relativity of time values. The value of time ostensibly varies with the value of space it occurs in.

Refer: Einstein's 'non-absolute relative space', and 'non-absolute relative time'. For which, until here and now, until further notice, there are not even any failed explanations.

Of course, in a 4-D universe, the value of time and space (4-D space-time) quite inevitably varies, from coordinate system to coordinate system. The speed of light for example, is ever-increasing, while remaining constant, relative to the coordinate system from which it originates and in which it is measured. The value of time being covariant with the smaller and larger - earlier and later - 4-D space-times it occurs and/or is measured in.
