The concept of going "faster than the universe" or going "outside" the universe is not well-defined within our current understanding of physics. The expansion of the universe is not like the motion of objects within space; it refers to the metric expansion of space itself. According to our current understanding, there is no "outside" to the universe that one can travel to.
It's important to note that the expansion of the universe doesn't involve objects moving through space faster than the speed of light. In fact, the theory of general relativity, which is our best description of gravity and the structure of the universe, prohibits objects with mass from reaching or exceeding the speed of light.
The nature of what lies beyond the observable universe is still a topic of speculation and active scientific inquiry. The observable universe represents the portion of the universe that we can currently detect and observe based on the limited time it took for light to reach us since the Big Bang. However, the universe may extend beyond our observable limits, and the properties or structure of that region are still unknown.
Various cosmological models and theories propose different possibilities for what might exist beyond the observable universe, such as the multiverse hypothesis, extra dimensions, or other speculative concepts. However, these ideas are still highly theoretical and not yet supported by empirical evidence.
It's important to approach these concepts with caution, as our understanding of the universe is continually evolving through scientific investigation and observation.
