If interstellar space is full of gas that is curious and possible problematic. Velocity meeting resistance creates (micro)friction. Friction means loss of momentum. Sure we're talking about tiny changes but they would be both cumulative and exponential over time.

And researchers studying those grains say that 4.4 billion years ago, Earth was a barren, mountainless place, and almost everything was under water. Only a handful of islands poked above the surface. Scientists at the Australian National University are behind this study, led by researcher Dr. Antony Burnham. The mineral grains in the study are the oldest rocks ever found. They’re 4.4 billion year old zircon mineral grains from the Jack Hills of Western Australia, where they were preserved in sandstone formations. 5 hours ago, Guard Dog said: Well oceans are teaming with life. Even in the Arctic and Antarctic. So I wouldn’t call it barren. It would definitely suck for us though. Link to comment Share on other sites More sharing options...
