In summary, a question was raised after watching a Sam Harris conference regarding determinism and the origins of the universe. The conversation delves into the idea of determinism being compatible with the big bang theory and whether the initial state of the universe being homogeneous would contradict determinism.

After watching a Sam Harris conference a question came to my mind.
Maybe it's been discussed several times, but I couldn't find any of that.

The starting point is that, according to determinism, the state of the universe in instant $t_1$ could be theoretically determined knowing its state at a previous instant $t_0$.
Well, let's take it for granted, which is not by the way.
Let's go back in the past, where every instant is predetermined by the instant before.
We may eventually arrive to a beginning, let's say the big bang.

Question is: what if all the matter at a certain moment (the first moment) was in an homogeneous state ? If all the matter was compressed into a hot dense sphere of homogeneous matter, then how can determinism be true ?

Otherwise, there must always be, in any moment, as much variables, as we find in a successive moment, otherwise it's not possible to determine the causes of the actual state of universe.
Is then determinism compatible with big bang theory ?

Related to Questioning Determinism: Exploring the Compatibility with the Big Bang Theory

1. What is determinism and how does it relate to science?

Determinism is the philosophical concept that all events, including human actions, have a cause and effect. In other words, all events are determined by previous causes and cannot occur randomly. In science, determinism is a fundamental principle that guides the study of cause and effect relationships in the natural world.

2. Can determinism coexist with free will?

This is a highly debated topic in philosophy and science. Some argue that determinism and free will are incompatible, as determinism suggests that our actions are predetermined by prior causes. Others suggest that free will can exist within the framework of determinism, as our choices and actions may still be influenced by our individual beliefs and desires.

3. How does determinism relate to scientific theories and laws?

Determinism is a key concept in scientific theories and laws, as it suggests that all natural phenomena have a cause and effect relationship. This allows scientists to make predictions and understand the underlying mechanisms behind observed phenomena.

4. What is the role of determinism in predicting future events?

Determinism plays a crucial role in predicting future events, as it suggests that every event has a cause and can be traced back to previous causes. By understanding the underlying causes and relationships, scientists can make accurate predictions about future events.

5. Are there any scientific fields that do not follow the principle of determinism?

While determinism is a fundamental principle in most scientific fields, there are certain fields, such as quantum mechanics, that challenge the concept. In these fields, the behavior of particles and events at the microscopic level may appear random and not fully determined by prior causes. However, even in these fields, scientists seek to understand the underlying causes and relationships that govern these seemingly random events.
