The core heart of darkness, no appreciable air to scatter light, vast vacuum to transit our voices nowhere, the community of inert planets, stars, galaxies, and clusters – these are the words to define outer space. [1] But we can scatter our view; we can transit our volition and go through the core knowledge and broad mystery that the immense outer space possesses. In reality, the profound understanding of the world we live in helps us survive in it and develop our lives. [2] And, this understanding is vested in the knowledge of ancient histories, present facts, and future possibilities, all of which are derived from space.
In 1929, Edwin Hubble showed that nearly all galaxies he observed are moving away from each other which he described as a redshift phenomenon, and tied it to the theory of expanding universe. [3] Additionally, in 1965, Arno Penzias and Robert Wilson accidentally found the CMB (Cosmic Microwave Background) radiation which represents the heat leftover from the Big Bang. And these both phenomena are the step forwarding evidence of our origin. [4] And these utter the Big Bang theory which gives us the knowledge of how time and space started their journey for the very first time.
Present observation endures the mysteries and often comes up with incredible facts and possibilities that humans have been anticipating for decades. As an example, Newton’s three laws of motion, which astronomers used to understand the fundamental concepts of the universe. [5] Over time, thinking about space deeply lead Einstein to develop first the revolutionary special theory of relativity and then the general theory of relativity along with the space-time, space-curve concept, and the breakthrough equation E= mc^2. [6] These provided us with insight knowledge of quantum mechanics, global positioning systems, electromagnets, power generation, and so on. [7] Even so, by observing and learning the innate facts of the universe, we are on the verge of displacing the moon and Mars as our second home. Thus, we are learning the facts our universe possesses, and the laws universe hid.
Furthermore, observing space literally brought the chance to predict future possibilities and dangers coming towards earth. A prediction shows that a potentially dangerous asteroid called Bennu has a 1 in 1,750 chance of hitting Earth between now and the year 2300. [8] We are even getting weather and climate-changing news through the satellites beyond our atmosphere. By observing space, scientists are also gathering knowledge to predict future scientific events or possibilities. Such as Douglas Finkbeiner (professor of astronomy and physics at Harvard University) predicted about black holes and said, “I think the standard story is that they lead to the end of time,”. [9]
To summarize, space is a potential of millions of facts, laws, and mysteries. By observing space, we can learn about our history, our origin, and how everything began; we can learn about how our current universe works and how to deal with it in order to survive and develop; and finally, we can learn enough to predict the future possibilities. After all, it’s all about the thirst for knowledge and a vast source of knowledge
