Assuming the concept of a "KLEINBOTTLE" applied to a four-dimensional universe where n+1 is >= 4

Considering the concept of a "Klein bottle" applied to a four-dimensional universe or higher, where N+1 is at least four(greater than or equal to four), is an important step in examining why our universe continues to expand. In fact, many scientists are trying to understand why the universe expands; some say it is caused by the Big Bang (Big Bang theory), but apparently, none of them can provide clear and satisfying answers. Since a Big Bang is just a once-and-for-all action, which may not persistently provide energy that causes the universe to persistently expand. In this research paper, we aim to interpret the gravitational wave of a conceptual idea, developed from the collision of two neutron stars assumption, which involves two black holes. This creates a wave similar to a micro Big Bang wave, which spreads throughout the universe (at the edge), causing a rippleeffect that pushes the universe forward to expand. We believed that these gravitational waves may become and accumulate to form a force, which we believe is part of dark energy.
