If the gravitation has very very tiny deviation from inverse square law！

AI Thread Summary
A tiny deviation from the inverse square law of gravitation would not significantly destabilize the solar system, as perturbations from other planets have a more substantial impact on Earth's orbit. Current observations suggest that any such deviation is minimal and unlikely to be noticed by people on Earth. The discussion references the Pioneer anomaly, which may relate to perceived deviations in gravitational behavior. Participants suggest merging this thread with a related discussion in the General Physics section for further exploration. Overall, the consensus is that while deviations exist, they do not pose a major threat to solar system stability.

If the gravitation has very very tiny deviation from inverse square law！our solar system became unstable? If so ,how long people on the Earth can notice it?

It does have a tiny deviation, and it doesn't make much difference. The planets have a much larger effect on perturbing the Earth's orbit than relativistic corrections.
 
What deviation from GR did you have in mind? I don't see any.
 
Perhaps Phrak is talking about the pioneer anomaly?
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
