For the first time, astronomers have captured an image of the supermassive black hole at the center of our galaxy, known as Sagittarius A. Is it necessary to believe in something only after we are able to physically observe it? Scientists like Prof. Stephen Hawking have accepted the fact that black holes exist even though this kind of a physical observation is possible only now. We, as humans cannot see an object which is just a mile away. Science had shown the vastness of observable universe. It will take trillions of years to get to the end of observable universe and we may still not get there as it is expanding at a faster rate.
It is pertinent to ask what Stephen Hawking also finds perplexing: “We find ourselves in a bewildering world. We want to make sense of what we see around us and to ask: What is the nature of the universe? What is our place in it and where did it and we come from? Why is it the way it is?”
