This seems reasonable to me in our 4.5 billion year old system. That novas come and go and affect us greatly. Was there accomplished life before? There is no way to know unless they survived to tell the tale.

So this LT starbit has an eccentric orbit that briefly touches the Oort cloud shedding anti matter. Our system every 5,000 y experiences heliospheric compressions down to Sol. All planetary bodies are heated via compressed gases. The energy field radially compresses, the planets experience increasing compression, then the Majorana transform of suspension, then the back of the energy field that is antimatter in which the planet releases the core heat via crustal fragmentation. The remains of this are what we identify as plate tectonics.

When the energy field releases compression the heliosphere returns to what we consider normal and the ferocious weather is due to the released heated gases.

As the field has since 25,000 y been decreasing in energy, first Venus, then Earth, then Mars has failed to experience the Majorana transform and the back of the energy field. The planet experiences the greatest possible compression, no Majorana transform, or expansion. The compression is held until the energy releases. The planet then experiences violent heated gas release. This has happened on Venus which watchers from Earth described as a new star. Venus has never been a comet but has been brightly visible as the heated gases lit the surface. Earth has also experience this event of maximum compression and the subsequent blowout of compressed gases.

The current compression event will not compare with past releases but compressed earth gases will release. Our lack of knowledge is due primarily to the fact that invisible, ordorless, colorless gases are not considered fatal except in long term low dose such as radon daughter products.

Our own span is about 5 my. Since about the time of the world dryness due to the initial onset of energy from the Centauri nova. I suggest we are comparable to the wolves of Chernobyl. They survive because the radiative stress is offset by their being in their own kind of Eden. We noticably have survived because compared to our beginnings, we experience less stress. This may change due to population pressures increasing stress.

A more comprehensive view would indicate that cycles of creation and destruction are the order of the day for the universe at large.
