In our Universe there are at least billions of galaxies, each of them having billions of stars. But our Universe can be much bigger than what humanity has been able to see with telescopes. It could be millions of times bigger, and even without considering the theories regarding the existence of other universes (aka the Multiverse).
But what can you understand when distant galaxies are synchronizing with each other due to a mysterious structure? This is the conclusion of a recent study published in The Astrophysical Journal, which says that hundreds of galaxies are rotating in exactly the same way.
The galaxies are millions of light-years apart
The weirdest part is that the galaxies behaving in the same way are millions of light-years apart from each other. The only explanation is that they are connected by an unseen network of intergalactic structures, which are forcing them to synchronize in ways that astrophysics cannot explain for the moment.
Korea Astronomy and Space Science Institute astronomer Hyeop Lee said:
The observed coherence must have some relationship with large-scale structures, because it is impossible that the galaxies separated by six megaparsecs [roughly 20 million light years] directly interact with each other,
Scientists are acknowledging the fact that they need further data before being able to conclude anything.The discovery somehow points to the so-called “large-scale structures” which is, perhaps, the biggest known objects in the universe. These enormous structures are containing mostly hydrogen gas. They are making up a network called the cosmic web, by taking the form of filaments, sheets, and knots.
The discovery could rewrite cosmological textbooks, and it’s fascinating how many new things we are discovering about the Universe. About only a century ago, we thought that our galaxy is all that exists, but an American astronomer named Edwin Hubble changed all that. He discovered that there are countless other galaxies, and that they are moving away from us. Only a few years ago, we couldn’t be absolutely sure about the existence of exoplanets (planets outside of our solar system), but now we have found thousands of them, and the number keeps rising. What’s next?
