Space is a huge sea of unknown. We are simply specks of dust, trying to figure out the behaviors of giants. Thus it is apparent that the specks can not know much. For now. One of the biggest mysteries is the expansion of the universe; in the 1990s, we knew that theoretically, our ever-expanding universe was slowing down due to gravity, and that it would eventually collapse or keep expanding, just slower as time went on. However, thanks to the Hubble Space Telescope, we now know that to be dead wrong. Our universe is, in actuality, speeding up in its rate of expansion! This left scientists puzzled; it went against almost everything they had thought. Since there is matter everywhere, and that matter has gravitational attraction, so why wasn’t
