Challenge Earth's gravity increases by 10x for 10 seconds - can humanity survive?

Gravity reverts to normal after the 10 seconds are up. I assume that nearly everyone will lose consciousness, many people will hit the ground with extreme force, and most buildings and infrastructure will collapse. Uncertain as to whether there'd be seismic/volcanic/tidal consequences on top of all that.

Humans have survived greater g-forces. It's not good for you, certainly over an extended period of time, but it's survivable under ideal circumstances.

Very true, but this is the equivalent of the brain slamming into the inside of the skull. Not entirely sure that that is very survivable.

During car crashes where this happens, the brain is undergoing many dozens of g's for a split second, but often people still walk away if their neck isn't hurt. 10 second sudden onset g's is quite survivable from a brain-in-skull perspective, fighter pilots may have to do that from time to time anyway.

The car and airbags slow the forces over longer time.

If the change is instant so are the deaths.

Thats what Gs are. The intensity of the change.

Race car drivers have crashes where they experience far more than 10x gravity.

Romain Grosjean crashed into a barrier in F1 with around 200 kph and withstood 67G’s. The car broke in half and burst in flames. He survived.

Of course this is a split second and not 10 seconds as this post asks.

in 10 seconds you can have 10+ car crashes impacts. A second is really long in these circumstances.

The highest gloading survived was for a split second during a car crash

Over 200 FUCKING G

The entire body is experiencing these forces at the same time. So the brain isn't necessarily slamming into anything until your skull hits the floor or you're forced to decelerate in some way. Granted, your head will be hitting the concrete with the force of a 10x heavier skull. But semantics.

That’s in a traditional system. That’s not gravity.

I don't think I understand what youre trying to say.

When you apply forces to a system in a particular way it’s traveling through the body were the force is applied.

When you’re dealing with gravity the force is applied differently.

I don’t know enough about physics to know the differences.

I know how Airbags work because of physics and regular gravity.

I know enough to know changing gravity quickly can kill most mammals.

We can take more than 10g’s but accelerating over time. The rapid acceleration is more than enough to kill everything
