AI Thread Summary
The discussion centers on a hypothesis regarding the inequality of gravity in various parts of the universe as an alternative to dark matter and energy. A participant seeks the name of the physicist associated with this hypothesis, suggesting it may relate to Modified Newtonian Dynamics (MOND). Another contributor argues that the term "unequal gravity" is misleading and proposes "variable gravity" as a more accurate description. The conversation highlights ongoing interest in alternative theories to explain gravitational phenomena. The exploration of these concepts reflects a broader inquiry into the nature of gravity in astrophysics.

Lately I've interested into the hypothesis on the unequality of gravity in different part of the universe, as a subsitute to the existence of dark matter and energy. I'd like to investigate... the problem is that I forgot the name of the physicist who presented that hypothesis... Can someone give me a pointer? Thanks.

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 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
