30. Will the Universe Ever Stop Expanding?
If the universe ever obtains the correct amount of matter, dark matter, gravitational attraction, and even dark energy, it might come to a halt. When this happens, the universe will ultimately collapse.
Over time, the galaxies and stars, which are already moving due to previous expansion, will collide with each other. What we are all hoping for is the slowing down of the universe’s expansion, so that scientists are able to keep up with what is happening.
More advanced methods will always be tested in hopes of discovering more about our ever-changing universe.
