Do all galaxies have the same laws of physics?

Originally Answered: Do different galaxies have different laws of physics? No. The laws of physics would not be laws if they were not Universal.

What does every galaxy have in common?

Each galaxy has its own collection of stars, planets, black holes, neutron stars, moons, nebulae, asteroids, comets, and dark matter. Our galaxy is a barred spiral galaxy and is called the Milky Way. It has large spiral arms with a bulging disk and bar of stars in the center.

What galaxy is earth on?

The Milky Way
The Milky Way: Earth’s home galaxy.

What keeps a galaxy together?

What holds galaxies together? Gravity. All of the stars of a galaxy are all attracted to each other. There is also a large amount of matter that has never been seen (called “dark matter”) that helps keep galaxies together.

What are the 4 main galaxies?

Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.

Does the galaxy have an end?

Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

How many solar systems are there in the Galaxy?

How Many Solar Systems Are in Our Galaxy? The Short Answer: Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. Our solar system is just one specific planetary system—a star with planets orbiting around it.

Why can’t we see all galaxies?

Nonetheless, beginning sky observers might wonder how objects composed of up to a trillion or more individual suns could be so difficult to see. Of course, the answer is distance. Galaxies are so far away that, except for a few, they appear small and faint. Advanced observers regard observing faint galaxies as a challenge.

What are the characteristics of galaxies?

Through telescope observation, each galaxy has a specific size, shape, and structure. The morphology that a galaxy has is the essence of the Hubble galaxy classification. The 3 types of galaxies are: Galaxies are just large accumulation of stars, planets, and other solar remnants.

How do astronomers count galaxies?

Counting galaxies is kind of like playing a cosmic game of Where’s Waldo. Astronomers are tasked with counting every galaxy they can find within that tiny sliver of space and then extrapolate it out across the entire sky.
