MIT professor thinks life in the universe might be thermo-dynamically inevitable

Elsewhere in the universe...
Life in the universe may not arise out of sheer luck if Mr. England is correct. As energy naturally dissipates overtime, life becomes unavoidable as organic matter is better at dissipating energy. Whether life happens at this or that exact point in space and time is random. But it has to happen somewhere, probably in tons of places at the same time, given the size of the universe.

"It has often been said that one of the reasons we are yet to find life elsewhere in the universe is that it is rare; most think the development of life on Earth was a fluke.

But one of the most prominent young physicists in the world has claimed otherwise, saying that he thinks life is as inevitable as inorganic matter... The theory has been presented by 31-year-old physicist Dr Jeremy England from the Massachusetts Institute of Technology.
Dr England’s idea is based around entropy; namely, energy spreads out or dissipates over time. For example, a cup of coffee left in a room will eventually reach the same temperature as the room itself.

Energy will always seek the path of least resistance if left to its own devices, which is why things in the universe - including the universe itself - tend to ‘spread out',  also known as an increase in entropy.
the underlying aspect of his theory, is that while all matter - from rocks to plants - absorbs and dissipates energy, life is much better at redistributing it.

This means that, taking the coffee cup example but this time using molecules swimming in an ocean, the atoms will reorganise themselves into life because it is better at dissipating the energy in the water.
If true, the implications of Dr England’s theories are vast. Perhaps most importantly, it may suggest life elsewhere in the universe is not as rare as once thought, but rather is as common as planets and stars themselves.
