Current Theory of Expansion of Space: What Do Scientists Think?

In summary, the current theory of expansion of space is known as the Big Bang theory, which states that the universe began as a singularity and has been expanding ever since. This expansion is believed to be caused by dark energy, and is supported by evidence such as the redshift of distant galaxies and the cosmic microwave background radiation. While the expansion of space cannot be directly observed, its effects can be seen through various astronomical observations and mathematical models. Current research in this field focuses on understanding the nature of dark energy and its implications on the structure and future of the universe.

Does anyone know the current theory for the expansion of space?

I was thinking about this the other day. Do scientists think the universe is expanding as in extending in size? Because if it's expanding, won't everything expand with it? Including us.

The latest issue of Scientific American has a discussion of this in laymen's terms which looks really nice (i have just glanced over it at present).
Some of the more knowledgeable members at PF can provide you with more technical info.
 

Related to Current Theory of Expansion of Space: What Do Scientists Think?

1. What is the current theory of expansion of space?

The current theory of expansion of space is known as the Big Bang theory. It states that the universe began as a singularity and has been expanding ever since. This expansion is supported by various observations, such as the redshift of distant galaxies and the cosmic microwave background radiation.

2. How does the expansion of space occur?

The expansion of space is believed to occur due to the presence of dark energy, a mysterious force that is causing the universe to expand at an accelerating rate. This means that the space between objects is increasing at a faster rate over time.

3. What evidence supports the theory of expansion of space?

There is overwhelming evidence that supports the theory of expansion of space. One of the key pieces of evidence is the redshift of distant galaxies, which indicates that they are moving away from us. Additionally, the cosmic microwave background radiation, which is a remnant of the Big Bang, provides further support for this theory.

4. Can the expansion of space be observed?

While the expansion of space cannot be directly observed, its effects can be seen through various astronomical observations. For example, the redshift of distant galaxies is a result of the expansion of space. Scientists also use mathematical models and simulations to study the expansion of space.

5. What are some current areas of research in the theory of expansion of space?

Scientists are currently researching the nature of dark energy, which is believed to be the driving force behind the expansion of space. They are also studying the effects of this expansion on the structure of the universe and its potential implications for the future of our universe.
