Positive curvature, like that on a sphere, implies a finite universe, while zero curvature, as on a flat plane or negative ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

If the universe has only existed for a finite time, then we couldn’t actually have an infinitely large universe emerging from a finite initial state. However, we don’t know if the initial state of the ...

Infinite computation represents an emerging paradigm that extends classical numerical methods through the incorporation of infinite and infinitesimal quantities. By embracing non‐standard analysis, ...
