WIRED draws some interesting conclusions from the Independence Day: Resurgence Spaceship trailer.
I’m not sure what’s happening in this trailer for Independence Day: Resurgence, but here’s what I think: The aliens are back and not at all happy about losing the battle on Earth. As part of their plan for revenge, they deploy a large ship near the planet’s surface. The ship is so massive that it gravitationally pulls objects (like buildings) toward it. Again, this is just my speculation from the video.
What kind of mass would a spacecraft need to pull things off Earth? Let’s take a look at gravity and then make an estimate.
