teraseconds
Teraseconds are a unit of time equal to one trillion (10^12) seconds. The prefix "tera" signifies a factor of 10^12. A terasecond is an incredibly long duration, far exceeding human lifespans or even geological timescales. To put it into perspective, a terasecond is approximately 31.7 years. This means that events or processes lasting a terasecond are exceptionally slow or occur over vast cosmic distances and times.
The concept of a terasecond is primarily used in theoretical physics, cosmology, and astronomy when discussing
