The phrase "to end of time" is often used to refer to something that is permanent and everlasting. However, there are many other ways to express this concept using synonyms such as "forever," "everlasting," "eternal," "endless," and "perpetual." These words convey the idea of something without beginning or end and can be used to describe everything from love to the universe itself. Other synonyms that convey similar meanings include "infinite," "boundless," "timeless," and "unending." All of these terms offer an alternative way to describe something that is beyond the scope of human understanding or comprehension.
