And what happens when the atoms will be pulled appart by the expansion, in the Big Rip?

What frame of reference will show the atoms still in their place?

The current accepted theory in cosmology postulates that the rate of expansion of the universe is not low enough to point to a bounce, and not high enough to point to a big crunch, but it points to a 'heat death' of the universe in which (after many cosmological decades) all the matter in the universe will have been taken in and then emitted by black holes. Keep in mind that every theory is subject to discretion, this is just our current 'best guess' as to the future of our universe.

FAQ: Exploring the Science Behind the Big Bang Theory

What is the Big Bang Theory?

The Big Bang Theory is a scientific explanation for the origin of the universe. It suggests that the universe began as a single point of infinite density and exploded, expanding and cooling over billions of years to form the universe we know today.

How was the Big Bang Theory discovered?

The Big Bang Theory was first proposed by Belgian astronomer Georges Lemaître in the 1920s. It was further developed by scientists like Edwin Hubble and George Gamow in the 1940s and 1950s. The discovery of cosmic microwave background radiation in the 1960s provided strong evidence for the theory.

What evidence supports the Big Bang Theory?

There are several pieces of evidence that support the Big Bang Theory. These include the expansion of the universe, the abundance of light elements, and the cosmic microwave background radiation. The theory also accurately predicts the observed distribution of galaxies and the large-scale structure of the universe.

Are there any competing theories to the Big Bang Theory?

While the Big Bang Theory is the most widely accepted explanation for the origin of the universe, there are some alternative theories. These include the Steady State Theory, which suggests that the universe has always existed and is continuously creating new matter, and the Oscillating Universe Theory, which proposes that the universe goes through cycles of expansion and contraction.

Can the Big Bang Theory be proven?

While the Big Bang Theory is supported by a vast amount of evidence, it cannot be proven definitively. Science does not deal in absolute proof, but rather in theories that are supported by evidence and can be tested and refined over time. The Big Bang Theory is constantly being studied and refined by scientists, and new evidence may emerge in the future that could change our understanding of the theory.
