20. Are we alone in the universe?
A conundrum of anyone who’s ever lived and the subject of many a late night discussion is whether or not we’re alone here on Earth. Are there strange alien beings in our solar system or beyond? If there is life on another planet, how alike are they to us? How intelligent are they?
Scientists know that the universe stretches some 93 billion light years across, with 2 trillion galaxies, each with millions of stars and planets. In fact, some say there are 100 quintillion (1 with 20 zeros) of them. Others say more.
So the chances are, we’re not alone, despite no evidence being found, yet, of other life, intelligent or otherwise. Besides, wouldn’t it be rather haughty of us to think that we’re the only ones here? Could anything else be more intelligent than us, and be watching, and laughing at us?
Some scientists say that the universe is teeming with life and that the Big Bang that created Earth and subsequently life on it, is actually a common event within the expanses of the universe, rather than a unique or random one off event.
As space viewing technology comes on in leaps and bounds and we can peer deeper and deeper into the universe. Are we about to find little green beings asking to be taken to our leader? Only time will tell!
