If Thanos were to actually wipe out half of all life in the universe, the immediate result would be a catastrophic mass extinction across all planets, with devastating ecological impacts due to the sudden disruption of food chains and vital ecosystem balances, potentially leading to the collapse of entire ecosystems and the extinction of numerous species, including humans, even if some populations managed to survive initially; the long-term effects would depend on which species were disproportionately affected and the planet’s ability to recover, with some ecosystems potentially taking millions of years to re-stabilize.

Key points to consider:
Immediate chaos:
The sudden disappearance of half of all life would cause widespread disruption in all ecosystems, with many species losing their food sources or vital symbiotic relationships, leading to immediate population crashes.
Impact on food chains:
The loss of key predator or prey species could cascade through food chains, causing significant imbalances and potential collapses.
Human impact:
Even if humans were not completely wiped out, the loss of vital food sources and pollinators could lead to widespread famine and ecological collapse.
Microbiome disruption:
Even microscopic life like bacteria in the human gut could be affected, impacting human health and survival.
Long-term consequences:
The surviving populations would face a drastically altered environment, with new challenges like increased competition for resources and potential evolutionary pressures.
Varied effects across planets:
The impact on different planets would vary depending on the existing biodiversity and ecological fragility.
