So, say the Fine Structure Constant is not a Constant

In summary, the Big Bang theory is still very strong despite some unanswered questions. The redshift could be explained without expansion, and the other major achievements of the theory are still supported by observations. The cosmological background comes from the expansion of the universe.

Did we still have a big bang?

Would this be because the unit charge, Planck's constant or the speed of light is not constant or some combination of them would not be constant?

What do you mean by "not a constant" ?

My guess (because your question is far from having only one interpretation) is that you propose that the Big Bang theory could result from erroneous interpretation of data due to the failure to consider the possibility that the EM strength has evolved with time. If my assumption is correct, I understand that you refer to the red-shift, that could thus be explained without expansion.

Let us assume your theory does explain the redshift. What do you do with the other major achievements of the Bigf Bang theory ? How do you explain the relative abundance of elements ? Where does the cosmological background come from ?

Plus the fact that, the farther one looks, the jounger observed structures are. There are several unanswered questions about the Big Bang theory, but it occurs to be very robust an hypothesis.

This is far from being the most exotic or revolutionnary ever. Actually, every month one can contemplate this kind of exotic proposal. Strangely enough, most of them disappear as fast as they poped up :rolleyes: It is very healthy that the community constantly questions the very fundations of our paradigms. Maybe unfortunately for people who like changes, but fortunately for student who aim at learning something worth, those fundations are very well grounded.

The guardian is not a very authoritative scientific reference.

I think yes, we still have big bang.

Assuming the universe looks the same in all directions, and that there is just as much matter here as over there, it is possible to narrow the possible number of universe histories (and futures) to three. And they all predict a big bang.

if the unit charge were larger or smaller by only a small amount then atoms molecules could not form.

if Planck's constant, h, or the speed of light were varied by only a small amount then the conversion of mass to energy in our star the sun would result in the Earth being to cold or hot to support life.

Related to So, say the Fine Structure Constant is not a Constant

1. What is the Fine Structure Constant and why is it considered a constant?

The Fine Structure Constant, also known as α, is a dimensionless number that represents the strength of the electromagnetic force between elementary particles. It is considered a constant because it has been observed to have the same value in different experiments and under different conditions.

2. What would happen if the Fine Structure Constant is not a constant?

If the Fine Structure Constant is not a constant, it would mean that the strength of the electromagnetic force would vary in different situations. This could have significant implications for our understanding of the fundamental laws of physics and the behavior of matter and energy.

3. Is there any evidence to suggest that the Fine Structure Constant is not a constant?

There is currently no strong evidence to suggest that the Fine Structure Constant is not a constant. However, some theories, such as String Theory, propose that the Fine Structure Constant may have varied in the early stages of the universe.

4. What would be the implications if the Fine Structure Constant is found to not be a constant?

If the Fine Structure Constant is found to not be a constant, it could potentially revolutionize our understanding of the laws of physics and the nature of the universe. It could also have practical applications, such as in the development of new technologies.

5. How do scientists study the Fine Structure Constant and its possible variations?

Scientists study the Fine Structure Constant through experiments and observations of physical phenomena, such as the behavior of atoms and particles. They also use mathematical models and theories, such as Quantum Electrodynamics, to understand and predict the behavior of the Fine Structure Constant.
