The concept of destroying the entire universe by manipulating time is speculative and currently beyond the realm of our scientific understanding. Our understanding of time and its relationship to the universe is based on the current theories of physics, such as general relativity and quantum mechanics.
In these theories, time is considered a fundamental dimension of the universe, intricately connected with space. While time travel and manipulation of time are subjects of scientific and fictional speculation, there is currently no scientific consensus on whether time travel is possible or how it could be achieved.
The question of whether altering time could lead to the destruction of the universe is highly speculative and hypothetical. The potential consequences of such manipulation, if it were even possible, are unknown and depend on the specific mechanisms involved.
It's important to recognize that our current understanding of the laws of physics and the nature of the universe has limitations. The field of theoretical physics continues to explore and expand our knowledge, but any speculations about destroying the universe through time manipulation remain purely speculative at this point.
