You might assume that our universe is a wave complex bounded by a wave shell (a "bubble") that's expanding in a preexisting medium. You might also make assumptions about the properties of your assumed preexisting medium -- and what you would 'see' if you were "able to escape the boundary of the Universe", ie., if you could view things from outside the "bubble", would be based on those assumptions ... imo.Mind Bender said:I'm sure this is a tired question but I'm curious...if I were able to escape the boundary of the Universe, what would I see? The Universe supposedly resembles a "bubble." So...this cosmic bubble would have to exist within a larger medium, right?
The universe is made up of a variety of different elements, including matter, energy, and dark matter. According to current scientific theories, the majority of the universe is made up of dark matter, which is a type of matter that does not interact with light and is therefore difficult to detect.
While there is currently no concrete evidence of life beyond our universe, many scientists believe that it is possible. The vastness of the universe and the discovery of potentially habitable exoplanets have led to the belief that there may be other forms of life in the universe.
The observable universe is limited by the distance that light has been able to travel since the beginning of the universe. Beyond this edge, there may be more galaxies and structures that we cannot see yet due to the limitations of light speed. However, it is also possible that the universe is infinite and there is no edge to the observable universe.
The most widely accepted theory for the beginning of the universe is the Big Bang theory. This theory proposes that the universe began as an infinitely dense and hot point, known as a singularity, and has been expanding and cooling ever since. However, there are still many unanswered questions about the exact origins of the universe.
There are currently several theories about the fate of the universe. Some suggest that the universe will continue to expand indefinitely, while others propose that it will eventually collapse in on itself in a "big crunch." Another theory suggests that the universe will continue to expand but at a slower and slower rate, leading to a state of heat death where all energy is evenly distributed and no new stars can form. However, the true fate of the universe is still unknown and is a topic of ongoing research and debate among scientists.
