Question

Is it possible that in 13,000 years it will be summer in December in the northern hemisphere? Or do we artificially change the definition of the length of the year to ensure this never happens?

Answer 1

DELAY EVERY NEW YEAR by `20 min 14 sec` to keep off Nature's time precession

Explanation:

The Great Year of about 26000 years is the period for this

retrograde time motion that is attributed to the precession motion of

the Earth's tilt ( polar ) axis. In half of this period, we go back in time,

from solstice to summer and vice versa.

To neutralize this effect for our future generations,

we can DELAY EVERY NEW YEAR# by

`1/26000` year

`=1/26000 xx 365.26=0.01405` day/year

`=0.3372` hour/year

`=20,23` min / year#

#20 min 14 sec /year.
