AI Thread Summary
The discussion centers on Roche's limit, which describes the phenomenon where a smaller celestial body will disintegrate if it orbits too closely to a larger body due to gravitational forces. Participants clarify that Roche's limit specifically relates to proximity rather than size alone. The original poster expresses gratitude for the clarification, indicating that the concept had been a source of confusion. The conversation highlights the importance of understanding gravitational interactions in orbital mechanics. Roche's limit is essential for explaining the stability of celestial bodies in close orbits.

Does anyone know the name of the law that says that if 2 bodies of different sizes are orbiting each other, the smaller one will break up if its a certain size to the other one?

You may be thinking of Roche's limit. However, this says that the second body will break up if it orbits too close to the primary, not if "it's a certain size".
 
yes that's it! thank you so much. its been bothering me all day and i couldn't find anything on it. yeah i meant anything along the lines of the smaller body being so affected by the larger one that it breaks up hehe. thanks again
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

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.

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
