Firstly, it's important to clarify that atheism is simply the lack of belief in any deities or gods. It does not entail a specific belief about the origins or workings of the universe. Atheists can hold a variety of viewpoints on scientific theories, including the nature of gravity or the potential consequences of its strength.
The statement that if gravity were slightly more powerful, the universe would collapse into a ball is an oversimplified representation of the concept. Gravity is a fundamental force that plays a crucial role in the structure and behavior of the universe. Scientists have extensively studied the properties of gravity and its effects on cosmic structures.
While it is true that the strength of gravity influences the expansion or contraction of the universe, the actual behavior is more complex and dependent on several other factors, such as the distribution of matter and energy. The current understanding, based on cosmological observations and mathematical models, suggests that the universe is expanding and will continue to do so. The specific fate of the universe is still an active area of research.
It's important to note that scientific explanations seek to understand natural phenomena through empirical evidence, observation, and rigorous testing. Scientific theories do not rely on the existence of a god or supernatural entities as explanations. Atheists, as proponents of a naturalistic worldview, generally attribute the workings of the universe to natural processes rather than invoking the concept of a god.
Overall, the idea that a slight change in the strength of gravity implies the existence of a god is not a universally accepted argument among atheists or within the scientific community. Atheists may have different perspectives on cosmology and the nature of the universe, but their atheism itself does not hinge on specific scientific explanations or concepts.
