Exploring the Big Bang Theory: Evidence, History, and Controversy

  • Thread starter Sundance
  • Start date
In summary, some members of a forum are discussing the theory behind the Big Bang and the lack of understanding among some people. The conversation includes links supporting the Big Bang theory and a request for links about the "Big Bounce." The BBT is no longer debated in mainstream science, but there is a thread for discussing mainstream cosmology.

Hello All

Reading many posts I find people not understanding the theory behind the Big Bang.

I do not agree with the BBT, but! that does not make me right. I'm not emotionally attached to any theory.

Here are some links in support of the Big Bang, later I will post against. For now maybe discuss the supporting issues.

Tango at your speed.

If anybody has links that can support the Big Bang, please post them.

Space-time inflated then matter came later and fell together. And by this then radiated. This way of creating matter with finite density allows the Big Bang to get over its limiting infinite gravity.

Space first then matter then radiation to go Bang!

What do you have about the Big Bounce? Lately I don't hear so much talk about big "bang" and "singularity". Instead i hear about the proposed cosmological bounce.

This proposal goes back in time a little before where the old singularity was supposed to be.

Do you have any links about the Bounce? do you have some explanation or support links?
Please add them to your list!

Related to Exploring the Big Bang Theory: Evidence, History, and Controversy

What is the Big Bang Theory?

The Big Bang Theory is a scientific explanation for the origin and evolution of the universe. It proposes that the universe began as a singularity, a point of infinite density and temperature, and has been expanding and cooling over the course of approximately 13.8 billion years.

What evidence supports the Big Bang Theory?

There are several pieces of evidence that support the Big Bang Theory, including the observed expansion of the universe, the abundance of light elements such as hydrogen and helium, and the cosmic microwave background radiation. Additionally, the predictions made by the theory have been confirmed by observations and experiments, further strengthening its validity.

What is the history of the Big Bang Theory?

The idea of a universe that began with a big explosion was first proposed by Belgian astronomer Georges Lemaitre in 1927. The term "Big Bang" was coined by astronomer Fred Hoyle in 1949, and the theory gained significant support in the 1960s with the discovery of the cosmic microwave background radiation. Over time, advancements in technology and scientific understanding have refined and expanded upon the Big Bang Theory.

What are some controversies surrounding the Big Bang Theory?

One controversy surrounding the Big Bang Theory is the question of what caused the initial singularity and set the universe in motion. Another is the concept of inflation, a period of rapid expansion in the early universe, which is supported by some evidence but remains unproven. Additionally, some scientists have proposed alternative theories, such as the steady state theory, to explain the origin of the universe.

How does the Big Bang Theory relate to other areas of science?

The Big Bang Theory has implications for many areas of science, including physics, astronomy, and cosmology. It has helped to explain the formation of galaxies, the distribution of matter in the universe, and the origins of elements. It also plays a role in our understanding of the fundamental laws of nature and the nature of space and time.
