Explaining Planet Ejection in Planetary Forming Systems

AI Thread Summary
High-mass planets can indeed eject smaller planets during planetary formation due to gravitational interactions. When a massive planet approaches a smaller one, it can exert a strong gravitational pull, but if the smaller planet has enough velocity, it can be deflected into an escape trajectory rather than colliding. This phenomenon occurs because the smaller planet's speed relative to the massive planet allows it to break free in a new direction. The discussion highlights the complexity of gravitational dynamics in planetary systems. Understanding these interactions is crucial for comprehending planetary formation and evolution.

It is said that high massive planets can eject small planets in planetary forming systems. I don't understand that since gravitation is supposed to attrack things. Do you know of any article that expains that kind of phenomenum?

It attracts it, then the smaller planet, not having collided escapes with the same speed relative to the planet, but a new direction which puts it on an escape trajectory. See the explanations in the thread:

I'll check it out. Thanks.
 

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...

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.
