Questioning the Expansion theory

In summary, the current evidence suggests that galaxies at a certain distance from Earth tend to recede at a corresponding speed, providing evidence for the expanding Universe. However, due to the limit of the speed of light, the light we see from distant galaxies is not current and therefore, the expansion of the Universe may not be accurately reflected in these observations. This is taken into account in Hubble's Law, which calculates the recession velocity of galaxies. The misconception that light from distant galaxies being older was overlooked by astrophysicists is addressed by Chronos' response.

Current evidence shows that (in general) any galaxy a certain distance (D) from Earth will tend to recede from the Earth at speed (S). Also, galaxies at distance 2D tend to recede at speed 2S while those at distance 3D tend to recede at speed 3S. This is cited as evidence that the Universe is expanding ever faster. I take the opposite view.

Let’s take a galaxy and set D at 1X〖10〗^6 Light years (Ly). It will recede at speed S
Then a galaxy at 2X〖10〗^6Ly will recede at 2S.
And a galaxy at 3X〖10〗^6Ly will recede at 3S

However, due to the limit of the speed of light, we are not seeing current speeds or positions the light we see is not current.

So, since galaxy 3’s light is from 3X〖10〗^6 years ago, and since most galaxies that distance are receding at 3S from us, we can say that 3,000,000 years ago the Universe was expanding at rate 3S.

And, since galaxy 2’s light is from 2X〖10〗^6 years ago, and since most galaxies that distance are receding at 3S from us, we can say that 2,000,000 years ago the Universe was expanding at rate 2S.

And, since galaxy 1’s light is from 1X〖10〗^6 years ago, and since most galaxies that distance are receding at 3S from us, we can say that 1,000,000 years ago the Universe was expanding at rate S.

∴ The expansion of the Universe is slowing down.

Chronos' response suitably addresses the misconception in this thread. Given that this is a borderline 'personal theory', I will close this thread here.
 

FAQ: Questioning the Expansion theory

What is the Expansion theory?

The Expansion theory, also known as the Big Bang theory, proposes that the universe began as a singularity and has been expanding ever since, creating the vast expanse of space we see today.

How do we know that the Expansion theory is true?

Scientists have gathered evidence from various fields of study, such as astronomy, physics, and cosmology, to support the Expansion theory. This includes observations of the cosmic microwave background radiation, the redshift of galaxies, and the abundance of light elements in the universe.

What caused the expansion of the universe?

The exact cause of the expansion of the universe is still unknown, but the leading theory is that it was triggered by a rapid and powerful event known as the Big Bang. This event is thought to have released a tremendous amount of energy, causing the expansion of space.

Does the Expansion theory explain the origin of the universe?

The Expansion theory does not explain the origin of the universe, as it is limited to explaining the expansion of the universe after the Big Bang. The theory does not address what may have existed before the Big Bang or what caused it to occur.

Are there any alternative theories to the Expansion theory?

Yes, there are alternative theories to the Expansion theory, such as the Steady State theory and the Oscillating universe theory. However, these theories have not been supported by as much evidence as the Expansion theory and are not widely accepted by the scientific community.
