Information at Space Time

[Corey White]

Two planets (A & B) are 180,000 miles apart from each other,
and are sent a simultaneous signal from a third planet (C) which
is exactly 93,000 miles apart from both of them. This makes a
triangle.

As it happens half a light second is exactly 93,000 miles. But the
chances that the speed of light ends perfectly in a round number,
(especially in miles) is slim although we can ignore that for now.

The triangle is an isosceles, with two equal sides and two equal
angles.

For this experiment we send two signals to each of the planets
A & B at the same time, both signals being sent from planet C at
time T.

The signal to planet A will say that planet B received a signal at
T + 1/2 a second. And the signal to planet B will say that A received
another signal at T + 1/2 a second.

Now both planets A & B have received information about the other
planet at twice twice the speed of light!

For planet A to communicate with planet B by itself, would take
almost a whole light second (186,000 Mph), and then for planet B
to send a signal back would take another light second. But wait it
gets deeper.

If we assume both planets have clocks that are set to the same
time we can do another experiment.

Planet A sends a signal to planet B containing the time of its
transmission, which we call T1. When planet B receives the signal,
it sends another signal back with the time it received planet A's
message, which is called T2.

Then when planet A receives the signal it notes the time of the
arrival as T3. T3 is the amount of time it takes planet A to calculate
the distance to planet B. However, planet B knows as soon as it
gets the signal exactly how long it takes for the signal to travel to it
from A, because its T1.

In this cases T1 is 180,000 miles or almost 1 light second.
And T3 is exactly 360,000 miles or basically 2 light seconds.

While in or other experiment of simultaneous signals the information
is received to both planets at exactly the same time, and only has to
travel 93,000 Miles or approximately 1/2 of a light second!

Isn't it strange however that a 1 second round trip at the speed of light happens to be almost 360,000 miles (A perfect circle)?

Another strange coincidence:

Pi * 2 Miles = 10.1118 Kilometers,
Almost a perfectly rounded decimal that may as well be a unit of
measurement.

As for 180,000 miles being near 1 light second and also the half the
circumference of a circle. A triangle's angles always add up to
180 degrees as well. But to be fair science rounds up not down, so
the speed of light rounded up is better said to be 186,282 miles per
second.
