Is gravitational acceleration subjective?
Eclectic Eccentirc Khattak No.1
i.e. g=9.8 m/s/s or 32 ft/s/s but cognizance shows that results are
not tantamount if unit of time is expressed/ recorded other than
second e.g. m/half-sec/half-sec or m/hour/hour or m/min/min).
Mammoth difference can be observed in acceleration when change in
velocity occurs
- Per second - g = 9.8 m/s/s
- Per minute - g = 35,280 m/min/min
- Per hour - g =127,008,000 m/hour/ hour
Example: would following two objects A and B hit the ground
simultaneously if dropped at the same time?
Acceleration due to gravity of A = 9.8 m/s/s - [change in velocity
occurs per second]
Now just change the unit of time
Acceleration due to gravity of B = 9.8 x 60 m/s/min or 9.8 x 60 x 60 m/
min/min - [change in velocity occurs per minute]
So does it fix by the nature for the falling velocity of an object to
be constant specifically for the duration of one second and should
increases constantly only after every second?
If change in velocity occur per second then why instantaneous velocity
of falling object v = gt shouldn’t the unit of “g” be m/ instantaneous
unit of time / instantaneous unit of that time
Isn’t falling velocity of object changes/ increases at every fraction
of second?
Is there any known specific interval of time at which velocity
changes?

Is there any known specific interval of time at which velocity changes?

onslaught or any challenge.
An equation of instantaneous velocity of falling object = v = gt. This
means velocity changes/ increases at minuscule interval of falling
object & so acceleration also increases at that minuscule interval. We
know that unit of acceleration is m/sec/sec when velocity changes per
second but in aforementioned case velocity changes at minuscule
interval therefore shouldn't unit of acceleration be; unit of
velocity/ minuscule interval at which change in velocity occur.
I asked this “Is there any known specific interval of time at which
velocity changes?” so that we can put the value of aforementioned
minuscule interval in UNIT of acceleration in order to express it
properly.

but what is the CQM position on planck length, when space iself may or
may not become foamy? (whatever _that_ means!) or is space smooth all
the way down?

Fermi Gamma-ray Space Telescope
A galaxy located billions of light-years away is commanding the
attention of NASA's Fermi Gamma-ray Space Telescope and astronomers
around the globe. Thanks to a series of flares that began September
15, the galaxy is now the brightest source in the gamma-ray sky --
more than ten times brighter than it was in the summer.

"Because Fermi saw no delay in the arrival time of the two photons, it
confirms that space and time is smooth and continuous as Einstein had
predicted. "
NASA Gravity Probe Confirms Two Einstein Theories
A NASA probe orbiting Earth has confirmed two key predictions of Albert Einstein's
general theory of relativity, which describes how gravity causes masses to warp
space-time around them.
The Gravity Probe B (GP-B) mission was launched in 2004 to study two aspects of
Einstein's theory about gravity: the geodetic effect, or the warping of space and
time around a gravitational body, and frame-dragging, which describes the amount
of space and time a spinning objects pulls with it as it rotates.
"Imagine the Earth as if it were immersed in honey," Francis Everitt, GP-B
principal investigator at Stanford University in Palo Alto, Calif., said in a statement.
"As the planet rotates, the honey around it would swirl, and it's the same with space
and time. GP-B confirmed two of the most profound predictions of Einstein's
universe, having far-reaching implications across astrophysics research."
[6 Weird Facts About Gravity]
Gravity Probe B used four ultra-precise gyroscopes to measure the two gravitational
hypotheses. The probe confirmed both effects with unprecedented precision by
pointing its instruments at a single star called IM Pegasi.
If gravity did not affect space and time, GP-B's gyroscopes would always point in
the same direction while the probe was in polar orbit around Earth. However, the
gyroscopes experienced small but measurable changes in the direction of their
spin while Earth's gravity pulled at them, thereby confirming Einstein's theories.

I can post other open questions in physics [could be my ignorance] if
someone is interested in responding.
