Could it be that when we go into the solar slip stream of the planet Venus, old Venusian life-forms are ejected from the atmosphere, sending us these
viruses, which are trying to survive?
Long shot here:
At some point in ancient times, the planet we call Venus were in the orbit as we (Earth) are now. Life started at Venus. "Earth" was in the orbit of
Mars. Something hit Venus, killing 90% of all life. Only bacteria/viruses exists in the atmosphere by pure chance.
Some of them are blow off by the solar radiation and again by pure chance hitting earth at these intervals?
At some point in time planets are doomed to get to close to their star? Just like the continuation of the galaxy's super massive black hole?
Several misconceptions here.
Venus was never in Earth's orbit and Earth was never in Mars' orbit. What you might be thinking of is that the habitable zone around the Sun was much
smaller four billion years ago than it is now. That's because the luminosity of the Sun was much lower then. As the luminosity of the Sun steadily
increased over time, the radius of the habitable zone steadily expanded outward. Because Venus is closer to the Sun than Earth, Venus would have
warmed up first, then Earth, then Mars.
In about 4 billion years in the future, or so, the Sun will evolve into a Red Giant, and the habitable zone will probably be out beyond Mars'
orbit.
However, the luminosity of the Sun is not what determined when the planets first actually became habitable. In the early years of the Solar System,
there was a cosmically large swarm of comet and asteroid impacts on the planets of the inner Solar System known as the Late Heavy Bombardment. During
the LHB, the kinetic energy of the impacts brought the surface temperature of the planets up to high enough temperatures that liquid water was not
possible. After the LHB ended 4+ billion years ago, the inner planets cooled, liquid water was present, and life as we know it on Earth could
theoretically have started on either Mars or Venus. That was around 4 billion years ago, plus or minus.
Current models show that Venus probably had liquid water up until maybe 1.5 billion years ago, but by then it lost almost all of its original water,
probably due to being swept away by the Solar Wind. Life as we know it on Earth could have started on Venus before it did on Earth or Mars, but it
has not been able to survive on the surface for at least 1.5 billion years. The surface temperature of Venus is hot enough to melt lead and the
atmosphere is full of Sulfuric Acid mist. Hot Sulfuric acid will dissolve any organic matter--viruses, bacteria, and people.
And that's the basic problem with your theory. Viruses need hosts to replicate themselves, and there are no hosts on Venus.
