Can the earth be regarded as the red dust in the universe? Or is the whole galaxy so insignificant? Isn't that human being infinitely small? ! ! Too emotional.

The universe is too big, and the stars far away from the earth are hundreds of millions of light years. Think about the speed of light!

And our technology is now difficult to get out of the galaxy. There are hundreds of billions of sun-like stars in the Milky Way.

But at present, mankind has discovered billions of extragalactic galaxies as huge as the Milky Way!

Moreover, the earth is really too small in the universe, and it is quite big for us humans.

Think that the size of the earth is only1300,000 times that of the sun. Don't say the universe, just say the milky way.

Even the Milky Way alone has hundreds of billions of sun-like stars. And the diameter of the Milky Way is100000 light years!

The scale of the universe is unimaginable. This shows how small human beings should be in the universe. .
