AI Thread Summary
Mars is considered almost sterile primarily due to its insufficient gravity, which cannot retain a significant atmosphere or oceans over time. The idea that a solar mass of plasma from a coronal mass ejection (CME) could have stripped Mars of its atmosphere is dismissed, as such an event would leave nothing behind. The discussion also touches on the historical mass of the Sun and its implications for Mars' conditions. Overall, the conversation concludes that the speculation surrounding CME events and their impact on Mars is not productive. The topic is deemed too speculative to warrant further exploration.

During the many millions of years that Mars has existed is it possible a random CME event released a solar mass of plasma that struck Mars and powered off the Martian atmosphere and the Martian ocean(s) and made Mars almost sterile?

Not really no. A solar mass of plasma leaves nothing left where the sun is.
 
Or prior to that, the sun had twice the mass it does today! :-p

Mars doesn't have the gravity required to keep much of an atmosphere or oceans for a long time.

If the Sun had twice the mass maybe Mars did also before getting struck by a blow torch blast of Solar Plasma. There are lots of possibilities over billions of years. We living organisms called humans are an example of what can happen given enough time and opportunity.

Please explain futher. Aren't we Stardust?
 
1-1=0.

This is too speculative to be useful. Closed.

Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
