Stars rotating around planets

Surely there must be one or two super-planets out there knocked out of orbit by colliding galaxies... it seems possible. And if it can happen, it probably will?

Nope, if a planet had the mass of a star it would become a star. that is the difference.
If it kept on growing in mass it would eventually collapse as a Black hole.

True

If it kept on growing in mass it would eventually collapse as a Black hole.

Planets do not usually grow to be stars, except in the initial formation of a solar system from the stellar gaseous disk when a binary star solar system forms, and a larger planet than Jupiter acquires enough mass to go nuclear.

When two galaxies collide there needs to be more explanation as to what happens to the black holes, stars and planets. Things do get messy, and the explanation is somewhat involved. First when galaxies collide most stars involved do not collide with other stars, because of the vast distances involved. To discuss this further the base fact that the gravity of the black holes rules the consequences. Nothing gets tossed out into space beyond the galaxies.

The biggest effect is the super quasar formed in the merging of the black holes. The stars caught in the collision path of the black holes will be most effected and toast. The intense quasar electromagnetic radiation will eventually be devastating to life on planets. In the collision of the galaxies the black holes will likely orbit each other and gradually merge, and intelligent life in other galaxies will see a new quasar in the heavens.

all of you useful posts have been dealt with

No they have not, you actually ignored my reference and unethically provided incomplete references.

rogue planets.....do not orbit

From: https://www.google.com/search?sourc...4j0j1....3..0....1..gws-wiz.....0.jBtIZKFIyns

A rogue planet is a planetary-mass object that orbits a galactic center directly. Such objects have been ejected from the planetary system in which they formed or have never been gravitationally bound to any star or brown dwarf. The Milky Way alone may have billions of rogue planets.

I say.....planets orbit stars

you say.....everything orbits the center of the galaxy

you have no line drawn by your definition
I do

No I said, "Rogue planets DO NOT orbit stars, and rogue planets orbit the galaxy center, Repeatedly plain English backed up by references.

It seems to be true. It seems that no object in space is truly 'on it's own' but rather, is subjected to another, larger object.

...But it's been said that space is expanding! So how billions of supermassive black holes seperate from each other, despite their immense gravity, means that there is either some other unidentified force occuring, as every action has an equal or opposite reaction..? Or the outward thrust of the big bang was stronger than every black hole in existance combined.

But the gravity of two black holes in space should be strong enough to draw them to each other, because they're not seperating from each other very quickly. So it seems weird that this is not happening.

But I don't think so.

The universe is expanding, because all the celestial objects we have observed are moving away based on the observations of red sift of the light, but the red shift of their light from different celestial object is moving away at different rates. There are local regional groups of universes called super clusters, and part of their movement is toward the center of these super clusters as the universes are attracted to each other and often collide and merge.

I have reference and posted as such

you made denial and quoted some other reference

so...you believe in the closed universe theory?
the universe is expanding.....but
will fail to continue and fall back into another primordial singularity

and the quote I found is common

if you prefer to lump a large object into the class of lesser items......I don't really care

but planets orbit stars

The quote you used is common, but selectively incomplete and inaccurate, and not from a complete definition that reflects the scientific evidence.. Common definitions do not meet the standard of science. There have never been any rogue planets that have not orbited the galaxy.

You sure are a bitter stubborn losser.

Not all planets orbit stars. Rogue planets orbit galaxy center by the scientific definition:

A rogue planet is a planetary-mass object that orbits a galactic center directly. Such objects have been ejected from the planetary system in which they formed or have never been gravitationally bound to any star or brown dwarf. The Milky Way alone may have billions of rogue planets.
