UNKNOWN UNIVERSE
Dear HIW,
Could there be any possibility of life made out of dark matter or any other matter in the universe? Could there be life in 95 per cent of the universe which is unknown?

As you rightly state, the majority of the universe is unknown, and many speculate that for life to have arisen in the tiny percentage that we know of, it’s likely to have also occurred elsewhere. Dark energy makes up around 68 per cent of the universe, while around 27 per cent is dark matter. This differs immensely from the observable universe, as it does not form in clouds. The majority of this invisible dark matter doesn’t interact with anything, meaning life would be unable to form. However, a small amount might be able to host life. Scientists group all types of dark matter under one name, but that doesn’t mean that all dark matter is the same. There may be a variety of dark matter particles, combining to form dark galaxies and maybe even some form of dark life. But while it remains ‘dark’, any answers remain speculation.
