It's a miracle that such an idea has made its way to the MSM...
The idea of a large gas giant, or other massive object out lingering in the very extreme distances (as in the vicinity of the Oort Cloud...and the
other feature out there, the "Kuiper Belt"....closer in, around, and outside the orbits of Neptune and Pluto. About 30-50 AU) is not new.
Problem has been two-fold: The theory cannot be confirmed, until there is observational evidence. Either a "sighting", which is extremely
unlikely, due to the vast distances. (Difficult also, because planets have no inherent "light" of their own, we only see them because they
reflect)....in other words, it's not a "star", undergoing nuclear fusion, and thus shining. Because, well....THEN would be much easier to see,
Second aspect of the distance is the physics of gravity, and its effects....the Inverse Square Law of gravitational attraction. Double the distance,
and the amount of gravity influence goes down by a factor of FOUR. Double that again, and it drops by a factor of EIGHT. Etc.....
Take our Earth, for example....and ocean tides. By comparison, the Sun is EXTREMELY more massive than our Moon, yes? But, which one is closest?
Yup! So, the Moon affects our tides, whereas the Sun? Well.....any effect it could possibly exert? Minuscule! Yes, it's far, far more massive,
but its distance diminishes its influence.
NOW...any celestial body lurking out in the Oort Cloud area....well, that is about 30,000 to 50,000 AU
out there!! That is nearly one Light
Year! AN [AU]...is an "Astronomical Unit". ONE "AU" is the distance from Earth to the Sun, on average. About 93,000,000 miles, or about
Some sources postulate that remnants of the Oort Cloud extend as far as THREE Light Years! Heck, the closest star, Alpha Centauri, is about 4.3 Light
Years! So, really, our Sun, and Centauri, are quite close, astronomically speaking....and we share a "backyard" full of garbage! (In a sense....)
Of course, the Oort Cloud is spherical....."Kuiper" a bit more aligned with the orbital plane of our planets, more or less. We think.
SO, let's make at least ONE thing clear, before it gets out of hand: This object? NOT the so-called "nibiru". In fact there IS NO SUCH THING as
"nibiru"! (Except in fiction and legend).
There seems to be a serious lack, in modern general population, of astronomy understanding, and teaching, it seems. The sizes are vast, and difficult
to comprehend, which is one part of the problem......
Some learning websites:
There is a thread on ATS, unfortunately the title uses the term "Planet X" (which too many people associate with the fictional "nibiru". Most
scientists and astronomers who may use the "X" think of that as the Roman Numeral for TEN (10). AS IN, it would be the tenth "planet"....Pluto
being formerly the ninth "planet", now a "dwarf planet, or planetoid". ..still, very distant objects are being discovered.....Pluto is now (as of
about 2006) considered "tenth"....so,t he "X" can mean "unknown"....or "unnamed", if you prefer.....
Other people ("nibiru" believers, mostly) see the "X" and think of the TV show "X-Files", apparently....sad.....
