I don't need to say anymore.
That's for sure, see that you don't...
I am sure your grandkids will love you as you direct them towards the
'sidereal time' reference which is meant to contain the 3 basic
planetary facts and from the looks of the new and modified
explanation,it appears the trekkie-like individual got to explain to
the world the shape,rotation and length of rotation for the entire
planet.There you go,all the achievements of humanity in space
flight,timekeeping systems and structural astronomy and the
explanation is from somebody who probably has argued the merits of
Spock or alien cartoons 5 minutes previously and the first thing that
appears on the world's most used search engine and one the world's
most utilized reference site.
Just in case,it disappears,here is the full trekkie explanation for
the motions of the Earth and its timekeeping system that all the
inquiring minds in the world will look at.The point being that this
dominant hoax where the 23 hours 56 minute 04 second value contains no
information about planetary shape and planetary rotation because it is
a fraud.You couldn't care less for your grandkids,that is the only
conclusion you have to consider,as what you believe exists only in the
imagination of Flamsteed in the late 17th century,a basic mistake that
has really bad consequences.
"Astronomers use sidereal time as a way to keep track of the direction
in which their telescopes need to be pointed to view any given star in
the night sky. Just as the Sun appears to rise in the East and set in
the West once a day, the Moon also rises and sets in this fashion, and
so do the stars.
Because the Moon revolves around the Earth about once a month, the
time between successive moonrises differs significantly from 24 hours,
the length of a day.
In turn, because the Earth revolves around the Sun once a year, and
thus the direction from the Earth to the Sun changes, while the
directions from the Earth to the distant stars do not change, the
cycle of the apparent motion of the stars around the Earth also has a
period which is not quite the same as the 24 hour average length of
the solar day.
Time deals with when an event happens, or how long something takes.
The time of day, however, can be viewed as a concept that relates to
angles in space, rather than to time as such. If the time of day is
noon in London, that means the Sun is overhead in London; at the same
instant of time, the Sun would be rising in Chicago, and the time
there might be 6 AM. (The actual time difference is likely to be one
hour greater, because Britain has changed the time zone it uses to
facilitate communications with continental Europe.) Thus, 12 noon UTC
and 6 AM CST refer to the same time, but to different times of day in
their respective locales of applicability.
Maps of the stars in the night sky usually make use of declination and
right ascension as coordinates. These correspond to latitude and
longitude respectively. While declination is measured in degrees,
right ascension is measured in units of hours and minutes, because it
was most natural to name locations in the sky in connection with the
time when they crossed overhead.
In the sky, the meridian is an imaginary line going from north to
south that goes through the point directly overhead, or the zenith.
The right ascension of the part of the sky currently crossing the
meridian is the current local sidereal time, excluding that part of
the sky north of the north celestial pole or south of the south
celestial pole that is crossing the meridian the other way.
Because the Earth orbits the Sun once a year, the sidereal time at any
one place at midnight will be about four minutes later each night,
until, after a year has passed, one additional sidereal day has
transpired compared to the number of solar days that have gone by."
