## How big are we compared to the universe?

It is home to about 10-billion superclusters (like the Virgo Supercluster). It has an estimated 350-billion large galaxies (like the Milky way). It houses about 30-billion-trillion stars; that is 30,000,000,000,000,000,000,000 stars! The Earth is about 3.5 million times larger than a human.

How big are humans compared to the galaxy?

The size of an average human is 176.5 cm or 1.76 m while the diameter of the solar system alone is 287.46×1011m. Therefore, the solar system is about 163.33×1011 times greater than a human then the universe must be infinite times greater than a human.

How big is the universe we live in?

If inflation occurred at a constant rate through the life of the universe, that same spot is 46 billion light-years away today according to Ethan Siegel, writing for Forbes (opens in new tab), making the diameter of the observable universe a sphere around 92 billion light-years.

### How many Earths can fit in the universe?

#### How small is the earth compared to the Milky Way?

Answer: Assuming a diameter for the Milky Way galaxy of about 15 kpc, which is about 4.6×10^(17) km, and a diameter for the Earth of about 12756 km, the ratio of the diameter of the Milky Way galaxy to that of the Earth is about 3.6×10^(13).

How big is the universe compared to a human being?

Conveniently, the human size is about at the middle of the macro to micro levels of the Universe. Now the size of the universe * average human height/diameter of earth is 12,000 light years. So a creature that had the same ratio to the universe that we have to the earth would be 12,000 light years high.

How big is the universe according to Wolfram|Alpha?

According to Wolfram|Alpha, the: average human height/size of the universe [math]= 1.8\imes10^{-27}[/math] Now the size of the universe * average human height/diameter of earth is 12,000 light years. So a creature that had the same ratio to the universe that we have to the earth would be 12,000 light years high.

## What are the similarities between the human brain and the universe?

And the flow of information and energy between nodes is only around 25 percent of the mass and energy content of each system. In addition, there are similarities between the composition of the brain and the composition of the Universe. The brain is around 77 percent water. The Universe is around 72 percent dark energy.

What would the universe look like through human eyes?

If you look through a human’s eyes, the universe should be small/nothing. If you’re looking through the universe’s perspective we would be almost invisible/inexistent because of how small we would be. The problem is that we don’t know the universe we only presume it’s infinite and vast.
