Which object is the centre of the Universe according to the Heliocentric Model theory?

Answer 1

The Sun was assumed to be at the centre until it was discovered in the 19th century that the Sun is only an insignificant star among a billion in our own galaxy.

In modern theory the Sun is at the centre of the Solar System.

Answer 2

As our knowledge of astronomy has expanded over the past two thousand years, our concept of the "universe" has also expanded.

it's obvious to any farmer who stands on the ground and looks up that everything revolves around us; more specifically, it revolves around YOU. We're standing still, not moving, right?

Except we're NOT "standing still"; as our knowledge increased, the Greek philosopher Aristarchus of Rhodes realized 2400 years ago that the Earth was spinning and orbiting the "central fire". His ideas were discounted for a long time, but the observations of Tycho Brahe and the calculations of Copernicus determined that the Earth, and all the other planets, orbit around the Sun.

It was a while LATER that we discovered that all the tiny little stars in the sky are other suns as bright or more so than our own Sun, and only about 100 years ago that we determined that our Sun is way off to the side of the Milky Way galaxy. And it's only been in the last 50 years that we've determined that our own Milky Way galaxy isn't in the center of the universe.

And we now believe that we will never know where "the center" of the universe is, or even if the idea of "the center" has any real meaning.

Answer 3

Helios means "Sun".
