In summary, the conversation discusses a thought experiment where the age of the brane is compared to the age of the "full" universe and how this could potentially change one's thinking about the origin of the universe. However, the speaker also brings up the idea that the age of the universe may not be as significant as previously thought.

As a thought experiment, imagine this.

Suppose the age of the brane in which we exist is say the age we think that the "traditional" universe has existed.

Then suppose that the age of the "full", "real" universe (in which the brane resides) is such that its ratio to the age above is the same as the ratio of the age above to a nano-second.

Could this change your thinking about the origin of the "universe"?

The secret to where we came from is to realize that the 19 or 20 billion year age of "our" universe is like nothing.

Ah, the old greengrocer's apostrophe.

I don't think this is a thought experiment yet. It's just speculation.

So time is 'brane' dependent? I think that dodges the issue.
 

FAQ: Unveiling the Real Age of the Universe: Could It Change Our Thinking?

What is the current estimate of the age of the universe?

The current estimate of the age of the universe is approximately 13.8 billion years. This is based on data from the Planck satellite and other observations of the cosmic microwave background radiation.

How is the age of the universe determined?

The age of the universe is determined through a variety of methods, including observations of the cosmic microwave background radiation, the expansion rate of the universe, and the ages of the oldest stars and galaxies. These different methods are cross-checked and combined to arrive at a more accurate estimate.

Could the estimated age of the universe change in the future?

Yes, the estimated age of the universe could change in the future as new data and observations become available. Scientists are constantly refining their methods and technologies for measuring the age of the universe, so it is possible that the estimate could be adjusted in the future.

What impact could a change in the estimated age of the universe have on our understanding of the universe?

A change in the estimated age of the universe could have a significant impact on our understanding of the universe. It could potentially challenge existing theories and models, and lead to new discoveries and insights about the origins and evolution of the universe.

Are there any potential limitations or uncertainties in determining the age of the universe?

Yes, there are some limitations and uncertainties in determining the age of the universe. For example, there may be discrepancies between different methods of measurement, and there are still many unknown factors about the early stages of the universe's history. However, scientists are continually working to improve their understanding and reduce these uncertainties.
