What else can I help you with?
How do you use collisions in a sentence?
Billions of collisions have occurred in our galaxy.
Is the galaxy very crowded?
no everything in the galaxy is spread out evenly so there aren't any giant collisions that are going to happen hope this helps
Why the fact that the earth and the moon have different densities favors the collision theory of lunar formation?
It seems odd to postulate that the planets/moons in our galaxy were the result of collisions. If that were true, why have we not been witnessing recurring collisions-- with the creation of other new planets/moons?
Are there any individual stars in the space between galaxies?
Yes, there are. These generally come about when they are ejected from their host galaxy by the huge gravitational interaction involved in the collisions of galaxies.
Why are galaxy collisions common in the universe?
Galaxy collisions are common in the universe because of the vast distances between galaxies and the gravitational forces that pull them towards each other. Over time, these gravitational forces can cause galaxies to collide and merge, creating new and larger galaxies.
What term do astronomers use to describe a galaxy that has a jumbled scattering of stars?
Astronomers refer to a galaxy with a jumbled scattering of stars as an "irregular galaxy." These galaxies lack a defined shape or structure, distinguishing them from spiral or elliptical galaxies. Irregular galaxies often contain young stars, gas, and dust, and they can be the result of gravitational interactions or collisions with other galaxies.
Is the Andromeda galaxy going to collide with the Milky Way?
Wait about 2.5 billion years and you'll find out. Such collisions are relatively common - called an Intergalactic collision. The Andromeda Galaxy or M31 [See related link - Andromeda galaxy] is believed to have collided with at least one other galaxy in the past. It is possible, that our Solar System might be ejected from the new galaxy during the collision. Such an event would have no adverse effect on the system and chances of any sort of disturbance to the Sun or planets themselves are remote. [See related link - Milky Way Galaxy] Because of the vast "empty" space between stars, the two galaxies will more than likely merge into an Elliptical Galaxy [See related link - Elliptical galaxy] without any undue effect to the Sun or Earth. [See related link - Galactic collisions]
Can galaxies steal stars from one another?
Not generally, but galaxies do collide sometimes. In fact, the Andromeda Galaxy will probably collide with the Milky Way in about 3 billion years or so. In the collision, stars are often "flung" from one galaxy to the other, or thrown out of the original galaxy entirely. Follow the link below to see what happens when galaxies collide!
What are some examples of super elastic collisions?
Examples of super elastic collisions include collisions between two superballs or collisions between an electron and a positron. In these collisions, kinetic energy is increased after the collision due to the conservation of momentum and conservation of kinetic energy principles.
What describes collisions in which there is no energy loss?
Elastic collisions do not lose energy.
How do collisions affect reaction rate?
The more collisions the faster the rate.
Which types of collisions are the deadliest?
Head-on collisions are usually the most fatal ones.
