Is there a Path for Galaxies Moving Away?

[ranjanbloom]

We all know that Galaxies are moving away from each other at a great speed, Is there any specific path through which they are moving?

Again we know few things about the Universe like Moons rotate around Planets, Planets around star, stars around the center of galaxy. And it seems all follow a system & that is the Gravitational force.

Earlier astronomers felt like Earth is constant & Sun is moving around it, but gradually they came to know the actual fact. Till now we know about the Stars as they rotate around the center of galaxy i.e. the black hole, So it may happen black holes are also rotating around some massive force along with the Galaxy. If that is true then all Galaxies are having a path & it will reject the concept that Universe is Expanding.

Here One more thing is that the distance between two planets in our Solar system never be same always, sometimes we may see the distance is getting more & sometimes less. This all because of the paths & we know this, as these planets are much close to us as compared to distant galaxies.

I feel we can find out this once we have some more powerful Telescope that we have now.

Whatever the astronomers found till date about the Universe is nothing but an Organized System, every object is well placed with a specific path, whereas the fact that Galaxies are moving away from each other is not matching the whole concept that already proved by astronomers.

Except for ones near enough to each other to be gravitationally bound, they are all moving directly away from each other at a speed roughly proportional to their distance from each other (ie, the further apart, the higher the speed).

Till now we know about the Stars as they rotate around the center of galaxy i.e. the black hole, So it may happen black holes are also rotating around some massive force along with the Galaxy. If that is true then all Galaxies are having a path & it will reject the concept that Universe is Expanding.

Motion of galaxies can be easily measured via red-shift, so astronomers are pretty sure they know the recession velocity of the galaxies reasonably accurately.

Here One more thing is that the distance between two planets in our Solar system never be same always, sometimes we may see the distance is getting more & sometimes less. This all because of the paths & we know this, as these planets are much close to us as compared to distant galaxies.

Again, we can certainly tell whether galaxies are getting closer to us or moving away.

Astronomers will always want more powerful telescopes, but as far as confirming the Big Bang theory goes, the margin for error is already exceedingly small. The Hubble can already see and measure the speed of objects more than 13.2 billion light years away - just a few hundred million years after the Big Bang and not long after galaxies started to form.

Whatever the astronomers found till date about the Universe is nothing but an Organized System, every object is well placed with a specific path, whereas the fact that Galaxies are moving away from each other is not matching the whole concept that already proved by astronomers.

I'm not quite following: there are no big flaws in the BBT. The fact that galaxies are moving away from each other matches with the predictions of the BBT.

Thanks for your great explanation, I have one more question "What is the major factor behind the speed of any object in space?". The speed of a star, planet, moon all varies. E.g. If a planet is close to the star then it will be be having greater speed than the planet that is far away. Similarly Speed of the Galaxies are also vary to each other, What is the factor behind this?

Objects that are close enough to each other to be gravitationally bound are interacting due to gravity. That would be the planets, stars, etc. up through our local group of galaxies. All of this motion one way or another started as gravitational potential energy as the slight granularity of our early ball-of-plasma universe led to coalescing into these forms.

Similarly Speed of the Galaxies are also vary to each other, What is the factor behind this?

Beyond our local group of galaxies, the word "motion" as we normally think about it is not really applicable any more. Objects appear to be moving apart, but the reality is that the space between them is expanding. Though the word is often still used, it isn't the same kind of motion.

I would like to provide a response to this content by saying that the movement of galaxies is a complex and ongoing field of study in astrophysics. While it is true that galaxies are moving away from each other at great speeds, there is no single specific path that they are following. This is because the movement of galaxies is influenced by a variety of factors, such as gravitational forces from neighboring galaxies and dark matter.

The concept of a black hole at the center of a galaxy is based on our current understanding of the movement of stars and gas within the galaxy. However, it is still not fully understood how black holes themselves move within a galaxy, and whether they are also influenced by larger forces.

The idea that the universe is expanding is well-supported by scientific evidence, such as the observation of redshift in distant galaxies. This does not necessarily contradict the concept of an organized system in the universe. In fact, the movement of galaxies away from each other can be seen as a part of this organized system, as it is driven by the expansion of space itself.

As for the varying distances between planets in our solar system, this is due to their orbits around the sun and is not directly related to the movement of galaxies. It is important to note that the movement of galaxies is on a much larger scale and is not affected by the same factors as the movement of objects within our solar system.

In conclusion, while there is currently no clear understanding of a specific path for galaxies moving away from each other, ongoing research and advancements in technology will continue to deepen our understanding of this fascinating phenomenon. The universe is a vast and complex place, and it is through scientific inquiry and observation that we can continue to unravel its mysteries.
