Question: Have you heard of the twin earth theory?
Im not talking about life light years away from hear im talking about the exact same earth exept behind the sun orbiting it in the same time we do this may sound silly to some people in this field of science they may think it would effect the orbit of mercury but I believe there is a mirror earth behind the sun so if we went there everything would appear mirrored, it would appear backwards with antartica pointing up but to them it would appear like our world so this is what I think. 99.99% of the world has never heard of this even the secret service people whom ever they are would shrug their shoulders to this. I believe there is a small organization that is linked to NASA that ship some of our stuff like music,video games, books,T shirts. It's all harmless trade for objects and technology. The people of this world appear just like us and had the same series of events in history I theorize that mostly all the same towns and cities exist in both places. The reason its so hard to spot each other is because we orbit the sun in the same order. This is what I believe my theory... what do you believe do you believe this? what do you think? opinions?
We would most definitely be able to detect the gravitational effects of a twin Earth on the opposite side of the sun - we have found no such evidence. The concept isn't as obscure as you think, plenty of literature and movies/TV shows have made use of the idea, it is definitely out there - as science fiction.
We've sent many objects into space at angles that would allow for us to see such a planet. It wouldn't be hard to spot if it were there.
It is a fun idea, and a nice premise for science fiction (if those involved don't get too caught up in accuracy), but it has no scientific merit.
It is not a "theory" because, in science, a theory must be supported by some observations AND it must comply with (at least) the known scientific principles.
No one has ever observed a planet opposite Earth's position around the Sun (and yes, we have plenty of probes that have gone on the other side of the Sun, around the Sun, above the Sun, etc.).
Over 230 years ago, the mathematician Lagrange had already determined that the position exactly opposite Earth, around the Sun, is a region of instability. This would make it impossible to maintain a planet at exactly that position, on a permanent orbit (it might remain there for a while).
Because of the presence of heavier planets on different orbital periods (especially Jupiter and Saturn), that would make it even more impossible for such a planet to always stay exactly in line with the Sun, as seen from Earth. The planet would become visible within less than a century.
What you recite sounds a lot like the plot from old science-fiction novels from fifty years ago. I even remember an old TV series with that idea in mind.
And with the addition of a Goddess (in your additional details) it sounds even more like wishful thinking... but not a theory.
You're delusional. The Twin Earth Thought Experiment (it was never a theory, see below) had absolutely nothing to do with another planet in our solar system. It was just a thought experiment on the 'meaning of meaning'. It was simply pondering what would happen given a different frame of reference. It never implied that there actually was another Earth out there, much less one in our solar system. Even in the thought experiment it was supposed to be around another star like the Sun.... The problem with your "theory" is that we have sent probes all over this solar system. We know for an absolute fact that there are no planets over there on the other side of the Sun. As others have said the "theory" you seem to be talking about is just a sci fi plot, not a scientific theory. Not only would this be an unstable orbit that would not be possible in the real universe, but we've had probes over there and they never saw it..... You might also be confused by the fact that some astronomers consider the Earth a dual planet system. The other "planet" in this "dual planet" system is the Moon, not some twin of the Earth. The Moon is not the largest moon in the solar system, but it is BY FAR the largest moon in relation to its parent planet. Which is the reason why some consider it to be a dual planet system rather than a planet/moon system. Even so, no there are no other mysterious invisible planets in our solar system. There are probably still a lot of undiscovered tiny ice ball dwarf planets out in the region past Pluto. But no, no large planets much less a twin of the Earth in the inner solar system. We would have discovered this millenia ago.
Yup, heard it... there's even a movie about it from the 1960's.
Disproved in the 1990's when Voyager snapped a 'self portrait' of our solar system - where the only planet in our orbit was ours....
No there is not another earth.
