I don't think entropy and information are things, they're more like metadata about events that can occur (entropy) or have occurred (information).friend said:By definition nothing can ever leaves or enters the universe as a whole.
Entropy is the only quantity in the physical sciences (apart from certain rare interactions in particle physics; see below) that requires a particular direction for time, sometimes called an arrow of time. As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease.
According to the laws of thermodynamics, information cannot be created nor destroyed. This means that the information of the whole universe cannot be altered or erased, but it can be transformed or redistributed.
It is currently unknown if there is a limit to the amount of information in the universe. However, based on the current understanding of the universe, it is believed that the amount of information is infinite.
Information in the universe is stored through various forms of energy and matter. For example, the arrangement of particles and their movements can represent information. Additionally, information can also be stored in the form of electromagnetic radiation, such as light.
New information can be added to the universe through various processes, such as the creation of new particles or the formation of new structures. However, this new information is not created from nothing, but rather it is a transformation of existing information.
It is currently impossible for us to fully understand the information of the whole universe. This is due to the vastness of the universe and the complexity of its systems. However, through scientific research and advancements, we continue to expand our understanding of the universe's information.
