Early planetary formation thought

AI Thread Summary
The discussion explores the theory that planets may have formed after the Sun, considering the influence of the Sun's gravitational pull and solar emissions on early planetary formation. It raises the possibility that these forces could create Lagrange points that affect the distribution of elements and molecules in the solar nebula. However, there is skepticism about whether the Sun's emissions were strong enough to impact planetary formation or if they merely dispersed matter into the Oort cloud. Participants express interest in the implications of these ideas and invite further opinions on the topic. The conversation highlights ongoing debates in early planetary formation theories.

Greetings !

Some less popular theories, at this time,
suggest that planets formed or at least
began to form before the Sun had formed.
I'm not sure that I agree with that, but
it's worth remembering as another counter
example to the idea I just thought about.

Anyway, the idea I just thought about is:
Suppose that the planets formed after the
Sun(Sol) was formed. Now, is it possible
that the gravitational pull of the Sun on
the one hand and the pressure of the solar
wind and aspecialy solar radiation on the
other hand could've created certain La'grange
points for various types of ellements and
molecules in the early solar nebula that
could've somehow affected planetary formation ?
Or, were such points too far away for the powerful
emmissions of the early Sun which is also
why all the free matter got blown away into
our Oort cloud ?

All opinions are welcome. :smile:

Live long and prosper.

Greetings! Interesting theory! I hadn't heard of this before. It does seem like the gravitational pull of the Sun and the pressure of the solar wind and radiation could possibly create Lagrange points. However, it could also be that the powerful emissions of the early Sun were too far away to affect planetary formation and blew away the free matter into our Oort cloud. It's definitely an interesting question and I'm looking forward to hearing other opinions on this.
 
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?'
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...
