I think these phenomena follow the scientific facts defined in the classical mechanics, but not theories or definitions in Einstein's mechanics.
If you think that, you’re wrong. Instead of making proclamations, it would be better to actually study Newtonian mechanics, first of all, to learn that the trajectories of objects in an 1/r potential are conics; circles are conics, but not all conics are circles. Then study relativistic mechanics to find what changes.
Stam Nicolis. Thanks for your answer.
Study and reading only can not give the solutions. Difference focus/perspective and discussion from different researchers only can give solutions to the scientific problems and to meet challenges. If you don't know to give the right information to the technical questions. be silient and watch others views and information to the questions. Hope you can understand.
Stam Nicolis: See your and others' answers to a scientific question on the web-link: https://www.researchgate.net/post/Is_there_any_relation_between_gravity_and_centripetal_centrifugal_force?_tatpl%5Bac%5D%5B0%5D%5Bactor%5D=AC%3A38236483&_tatpl%5Bac%5D%5B0%5D%5Bid%5D=1651658211849277440&_tatpl%5Bac%5D%5B0%5D%5Bobject%5D=PT%3A649ecf52681bc7103905a99a&_tatpl%5Bac%5D%5B0%5D%5Bts%5D=1688227203&_tatpl%5Bac%5D%5B0%5D%5Bverb%5D=recommend&_tatpl%5Bs%5D=b5536c70152cd4a6d29c82e6462c1ebb40ae3685
Science isn’t subject to popular vote, but to study. That the trajectory of an object in an 1/r potential is a conic (whether it's a circle, a parabola or a hyperbola depends on the initial conditions) isn’t the result of a group discussion, but of a calculation, that anyone can learn to do, that is a standard exercise in any textbook on Newtonian mechanics, see for instance, here: https://web.physics.ucsb.edu/~fratus/phys103/LN/TBP.pdf.
How to calculate the trajectory of a relativistic particle, in a general spacetime is in any textbook of general relativity. A summary may be found here: http://www.astro.sunysb.edu/lattimer/AST390/gr_orbit.pdf
Stam Nicolis: Thanks again for your answer.
Do you know that several past and present Great scientists did not accept the Einstein's mass-energy equivalence. There are several publications regarding this. Kindly go through and understand them. Regarding the relativity of Einstein's theory and Observation of moving objects (from different frames) including the transformation/conversion of mass and energy, there are lots of disputes. Science refers to facts, definitions, concepts, ideas, mathematical derivations, formulae given/proved by Scientists like you. But wrong information giving by others can not be accepted and also that is not a science.
Stam Nicolis. We are living in electrical, electronics, and digital world.
Because Newton(atom), J. J. Thomson (Electron), Niels Bohr (motion of electron in outer orbits of atom), Rutherford (nuclear physics), ..., etc. These are the development/growth of science/physics.
Please don't escape by saying these are history of physics.
Stam Nicolis: You said: "Science isn’t subject to popular vote ....... summary may be found here: .... sunysb.edu/lattimer/AST390/gr_orbit.pdf"
This is about the trajectory of a projectile and its calculation.
My question is: Why?
Answers: A stellar system is a small number of stars that orbit each other, bound by gravitational attraction. A large group of stars is bound by gravitational attraction that's why, in the Universe, all the objects (except running in vacuum) are orbiting other object(s)or moving in a circular path.
Dear Chinnaraji Annamalai
If you are interested in what direction fundamental physics would have gone into, instead of choosing kinematic SR mechanics instead of electromagnetic mechanics, that was totally left aside 120 years ago, you may find this article of interest.
