Yes, there have been many that have collided over the thousands of years. As a matter of fact, it is predicted that our own galaxy will collide with our neighbor galaxy in the future.
Yes, some galaxies clide into each other because of the black holes that are in the middle of every galaxy.There has been a prediction that our galaxy will collide into another galaxy very close to us in about 3 million years.When the galaxies do collide into each other, they create a super nova.A super nova is a HUGE explosion of fire and flames.After the super nova, the 2 black holes in the middle of the galaxies will combine with each other and create an even BIGGER black hole.It's very interesting.Hope this helps.
Not Human explorers.
No, even though their orbits appear to cross, they will not crash into each other. This is because Neptune and Pluto are basically synchronized, with Neptune controlling Pluto's orbit.
Yes. Galaxies do sometimes collide.
Hubble's Law applies from everywhere in the Universe. In the broad sense, where ever you are other galaxies are moving away from the galaxy you are in proportionally to its distance from you. This is not an exact science because galaxies are gravitationally influenced by other galaxies and clusters but on average it is true.
Probably yes, even though no one has ever found any.
Each star moves around the center of the galaxy it belongs to, in circular motion. But since all galaxies in the the universe are moving away from each other that will unravel the repeated circles of rotation of the star around its galaxy center into helical path on an imaginary cylinder surface ever increasing in height in one direction outward and away from all other galaxies.
Who ever said Earth was the only one, what about other unexplored galaxies.
They barley saw each other
No, it is a statement, but there is a hypothesis that there is life in other galaxies, or even outside the solar system but in our own galaxy, but it can't really be described as scientific because no evidence has ever been found.
Probably not. The people who drive them have to be professionally trained to do drive it. There are only 2 zamboni machines, so they probably wouldn't crash into each other.
People have never been known to have ever visited other galaxies. With recent technological advantages, going to another galaxy may be possible in the future. As people have never manned a space trip to any space body besides the moon, the probability of traveling to another galaxy remains low, though not impossible. Also, as time goes by some galaxies are moving closer to the Milky-way galaxy, so traveling to foreign galaxies may become a higher probability. So... it is possible in the future. You never know... if people in those other galaxies exist, they may visit us first!
they played each other in 2004
No, gas particles can touch each other when they collide.
of course they did
Of course they do!
They have played each other 11 times to date.
Space and the galaxies. It is the main science ever discovered.
Yes, my galaxy is the Milky Way and it is going to collide with Andromeda. Cannot answer for people living in other galaxies.
