¿Cómo puede ser que el Universo sea infinito?<end_of_turn>
<start_of_turn>model
The question of whether the universe is infinite or finite is a complex and still debated topic within cosmology. To the best of my knowledge, based on information available as of September 2021, no definitive conclusion has been reached regarding the true nature of the size of the universe. There are different theories and approaches at play. Here are some perspectives:

1. Universe finite but without perceptible limits: Some cosmological models suggest that the universe could be finite in terms of its volume, but that it lacks perceptible limits. This would mean that we could travel in a straight line in any direction and eventually return to the starting point, as we would on the surface of a sphere, but without encountering tangible edges.

2. Infinite expanding universe: Another possibility is that the universe is infinite in terms of its size and is constantly expanding. This would imply that there are no boundaries in space and that galaxies and cosmic structures are distributed similarly in all directions.

3. Multiverse and parallel universes: Some speculative theories, such as string theory and the theory of parallel universes (multiverse), suggest that there could be multiple universes, some of which could be finite and others infinite. These universes could have different physical properties and dimensions.

4. Cosmological observations: So far, cosmological observations provide evidence that the observable universe is extremely large, but we have not yet reached a definitive conclusion about whether it is infinite or not.

Importantly, cosmology is a constantly evolving field, and scientists continue to research and refine our understandings of the structure and nature of the universe. The final answer to whether the universe is infinite or finite may be beyond our current technological and conceptual reach.<end_of_turn><eos>
