"Then what do you mean?"
Ifasta had already begun calculating. As a collective consciousness, it might even have guessed what information Chie's grandfather had left behind as the Third Divine Abomination.
But supported by reason, she remained silent, merely waiting for Su Wen to finish presenting all the points he wished to make.
Meanwhile,
Su Wen directed the fifth and final key point toward Makuhari Beach, Chiba:
"Chiba is the most crucial location.
Its ecliptic longitude is 140°, corresponding to the Sun's ecliptic longitude of roughly 142° ten years ago. The 2° discrepancy may have been a simplified value used by your grandfather. And the beachfront has an open, unobstructed view. When an antenna is aimed at the zenith, it can cover the entire celestial equatorial plane.
In other words, this was the central node he originally intended to use to transmit signals back to Ifasta.
Look at the three interlocking gears drawn here on the blueprint. The spacing between the teeth is 0.8 mm, which converts to 119.68 kilometers at the scale used. That happens to be the straight-line distance from Makuhari to Tsukishima.
And the angular diameter corresponding to that distance is exactly the same as the Sun's angular diameter as observed from Earth, about 0.5°."
"This isn't a coincidence."
At those words,
Caroline finally stopped listening. Taking advantage of the Tokyo sinking crisis, while no one was monitoring the peripheral data of certain Tokyo districts,
she used electromagnetic wave propagation simulation software and entered the parameters of each location to directly perform a precise comparison of these vital sites around Tokyo:
Hacker Miss followed the blueprints left by Su Wen and Chie's grandfather, simulating an S-band signal transmitted from Makuhari and amplified through Tsukishima, calibrated with Jupiter's orbital parameters, and Daiba, calibrated with Saturn's orbital parameters.
