What if the Earth’s Gravity Increases Twofold?

NASA researchers have finally discovered that Earth’s gravity… keeps changing. And scientists can’t guarantee that there won’t be any unexpected leaps in the near future! Even if gravity changes by only one percent, the consequences will be catastrophic.

So, you better hold on tight!

You’ll find out: can whales drown? Could Newton have been wrong in assuming what would happen if gravity disappeared? And most importantly, why do we even need gravity?
