Since the discovery of the big bang, we have considered the universe to be finite in age, it is estimated to be 13.82 billion years old. Since it is finite in age it CAN be infinite in size, but we don't know for sure.

WebThe finite age of the Universe and the finite speed of light combine to limit what we can observe of the Universe in several ways. There is a boundary to our observable Universe called the cosmic horizon. We cannot observe anything beyond that boundary because light from there has not had enough time to reach us—even 13.8 billion years has ...

WebMar 14, 2024 · The horizon of the observable universe arises because of the limited time its light has had to reach us. As time passes, more light from beyond the horizon will finally make it here and the horizon will recede accordingly. ...

The universe must contain a finite energy - sum of all matter and fields - or the mass-equivalent would collapse within its own gravitation. Said mass-energy is fractionally partitioned among elementary particles and their agglomerates. One then strongly expects there are a finite number of particles including extremely low energy photons ...
