The current scientific understanding suggests that the stars in the universe are not infinite in number, but the exact number is unknown. The universe is vast, containing billions of galaxies, and each galaxy can host billions or even trillions of stars. With such a tremendous number of galaxies and stars, it is challenging to determine an exact count.
However, based on observations and models, astronomers estimate that there are roughly 100 billion to 200 billion galaxies in the observable universe. Each of these galaxies can contain varying numbers of stars. The Milky Way, for example, is estimated to have around 100 billion to 400 billion stars.
It's important to note that our understanding of the universe is limited by our ability to observe it. The observable universe refers to the portion of the universe that we can see and study, which is limited by the distance light has had time to travel since the Big Bang. Beyond the observable universe, there may be regions that are currently beyond our detection.
Considering the vastness of the universe and the staggering number of galaxies and stars observed so far, it is highly unlikely that the stars in the universe are infinite. However, due to the limitations of our knowledge and technology, we cannot definitively determine the exact size or quantity of the universe's stellar population.
