SALT LAKE CITY — “Avengers: Endgame” is in theaters right now, giving fans a chance to see how the world would change after Thanos (Josh Brolin) snapped his fingers and wiped out half of the universe’s population in “Infinity War.”

Well, scientists recently explained what would REALLY happen to the Earth if there was ever a Thanos-like event.

Justin Christensen, a scientist in the department of physics at UCLA, told Fandom that the loss of close to 3 billion people would bring the world back to a population size akin to the 1970s. But the planet would quickly rebound to 2019 population numbers.

But Christensen said there would be many more deaths from the events following the Snap rather than the Snap itself. He said that there are probably 20,000 airplanes in the sky at any time, so about 25 percent of all planes would have their pilots disappear.

That means about an additional 500,000 people would die after the Snap from plane crashes alone.

And then there are car crashes to consider, too.

“There are approximately 1 billion vehicles (cars, trucks, buses, etc.) in the world, and about 10% of them are in use at any given time. If you assume just 1% of the surviving drivers still on the road following the Snap are killed in crashes with suddenly driverless cars, that’s an additional half-million fatalities,” according to Fandom.

And then, on top of that, the world’s infrastructure would slowly fall apart. Bridges, roads and buildings would slowly crumble and lead to possibly more injuries and deaths, too, according to Fandom.

“So, if you were one of those people who actually thought that Thanos’ plan was a good one, then you didn’t give this enough thought,” according to ScreenGeek. “It would destroy our planet as a whole, not save it. The Mad Titan lived up to his name, not giving enough thought to what he was doing, but rather simply being the villain that he truly is.”
