The origin of the milky way

How can you tell the shape of something if you're inside it? In the late s, astronomer Sir William Herschel addressed this question. Herschel reasoned that if the Milky Way was a sphere, we should see numerous stars in all directions.

The origin of the milky way

Origin The Milky Way as seen from a side view: Creationists reject the big bang theory because it contradicts the Biblical account, which has the Earth created first and the stars formed on the 4th day. And God said, "Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years, and let them be lights in the expanse of the sky to give light on the earth.

God made two great lights—the greater light to govern the day and the lesser light to govern the night. He also made the stars. God set them in the expanse of the sky to give light on the earth, to govern the day and the night, and to separate light from darkness. And God saw that it was good.

And there was evening, and there was morning—the fourth day. Some say the universe is close to 10 to 15 Ga a unit of time equal to 1,, years old. The majority of astronomers believe ninety percent of the universe's mass is dark matter ; of the ninety, twenty percent consists of hot dark matter, and cold dark matter makes up the other seventy percent.

Dark matter includes neutrinos, burnt-out stars, tiny chunks of ordinary matter, and clouds of mysterious particles.

Evolutionary astronomers have tried to conduct experiments to determine the role of dark matter in holding galaxies together with its gravitational pull. If galaxies didn't have dark matter to keep them together, their rotation would make them fly apart.

The report accessed the distribution of stars next to the galactic disk in a radius of parsecs a unit of length, equal to about 3.

Analysts could then infer the gravitational mass. The statement concludes that the local dynamical density is "well below all previous determinations leaving no room for any disk shaped component of dark matter".

Her findings revealed that there was no trace of dark matter within the galactic disk. An astronomer uses this symbol to calculate the progression of the universe.

The thought is that if our galaxy is anything like other galaxies in the universe, then that could potentially lead to the implication of a young universe. But rather than abandon earlier theories and hypotheses, researchers say that there must be a deposit of dark matter within the halo of the Milky Way.

Now researchers are trying to find other sources of gravity that hold the galaxies together. Waterfor example, is known as the universal solvent and is not only important to a planet, but necessary. Without its unique properties, life could not survive. The term circumstellar habitable zone CHZ is used to describe a ring-sized shape of the best places for the survival of life in a system.

Often times it depicts an area surrounding a star where water can last for a long time on a planet. But this term can be loosely applied to any system, even an inhospitable one. In that case, the CHZ would not be relevant. It was not untilthat the concept of the galactic habitable zone GHZ was born.

This gives an account for all of the habitable regions within the Milky Way galaxy. The amount of metallicity can neither be too much nor too little because it can pose a threat to life forms.
