Venus had liquid CO2 oceans?

venus liquid Carbon Dioxide oceansEarly Venus may have had oceans of CO2 (liquid Carbon Dioxide) according to a new theory as to why its physical features look similar to Earth and other planets, even including Titan.

At the moment Venus is hot and dry but has those puzzling Earth, Moon, Mars like geology features. So it had to have a massive liquid presence in the past, similar to Mars.

"This in turn makes it plausible that geological features on Venus like rift valleys, riverlike beds, and plains are the fingerprints of near-surface activity of liquidlike supercritical carbon dioxide,"

To see what the effects of supercritical carbon dioxide on Venus might be, Bolmatov and his colleagues investigated the unusual properties of supercritical matter. A great deal remains uncertain about such substances, he said.

If Venus was not formed or shaped as science thinks, then an ocean might not be needed? And supercritical carbon dioxide may not be needed.

This latest planet Venus theory shows what a mystery the geology of it is.
