Time Gravity Dip

Something to think about...

Note that the end speed seems not to change, therefore the second law / conservation of energy is not violated - but somewhere along the way, the effect of gravity shortens the overall time, thus increasing the overall speed (though the actual distance of travel also increased as well), so that the sphere with the longest way to travel paradoxically hits the target first.

This works even in repetition:

Now imagine the opposite - a cannon ball shot (or a rock hurled) straight up into the air, to fall down exactly where it was: the distance is zero (or, if you miss, very short), but time did pass - and the speed of the projectile was much higher than can be inferred from that resulting 'distance'; in fact, the higher its velocity, the more time passes until it's return, and the slower or lower the resulting overall speed (remember that the trajectory of any missile on earth is always longer than the actual distance to the target - but not in zero gravity conditions).

Or, more simply, imagine the dips in the two rail constructions not as dips, but as (somewhat slighter) humps. Why slighter? Because the universe is not symmetric.

These phenomena can be observed only near centers off gravity; and though they can be simulated to a certain extent (for instance, by fastening a projectile to a slingshot in space), the overall message is that gravity disturbs trajectories and so seems to bend time as well (you may imagine the second rail construction in an endless loop or as a closed circle).

360 Degrees - Division in Time and Space

360 Degrees The partitioning of time and space into 360 steps Partitioning a whole into 360 degrees / 60 minutes with a compass and a ruler as universal instruments for the division of space and time The partitioning of a full circle as a representative of the whole into 360 degrees goes back to Babylonian times of farming and simple technology - 5000 years ago, around 3000 BC to 300 BC. Our current decimal number system is based on the number 10; their numerical system was based on the number 60 . In those days, the emphasis was not , as it is today, on arbitrarily precise mathematics, but on those principally so; it was not about calculations ( these were then neither possible nor needed ), but about division and construction of artifacts with available aids . Within simple life, symmetry, dividing evenly, and fair and correct sharing, are of big, if not existential importance. Since reality itself is but an approxim...

German humor

😀 Rough and politically wrong. In a fake TV documentary many years ago, some faked 'Citizens of Poland' in very loud clothes 'claimed' that their deceased uncle had authored every pop song of the last century, and proceeded to prove this by playing them with tubas and other very loud instruments - making every one sound like a polka. The whole extended family joins in, ' Seductive Sis ' sings while her pay-by-call phone number is displayed on the screen, and so on. "Having stolen their electricity" (another bad cliche, if anything, we're stealing theirs), they are 'forced' to turn the volume down to a whisper from their side so as not to attract too much attention, thereby forcing everyone watching the show to turn up their own TV sets to *full volume* so as to even hear anything - knowing full well they would suddenly turn it up again at the other end, but not WHEN... After lulling the audience by drawing it into the nati...

Economics, Science, and Religion 2

[2] previous / next slide In 1859 , Charles Darwin published his observations on the origin of species , which introduced the concept of evolution into the social discussion: not only in the field of biology , but, as a side effect, in geology as well; the world was no longer static , a completed creation, but a dynamic one, constantly evolving; or at least it had been in the past . However, Creation itself was still in some way considered to be complete and static , at least as far as it was projected into the future ; meaning that evolution may have been the way things had developed up to the present , but no further ; the question why this should be so was carefully avoided. This is just one of the many unsolved paradoxes and mysteries resulting from the incomplete implementation of the discoveries made during the era of industrialization: If the world and its human inhabitants are the result of an evolutionary process, then that ...
