Earth's force field is real, and it's saving you.
The sun ejects 1.5 million tons of matter into space at an astonishing rate every second.
Earth's magnetic field blocks most of that matter, so we don't get microwaved to death.
Some space junk sneaks into Earth, crashing into the poles and creating the northern lights.
Without this barrier, we'd end up like Mars... a dead rock of trust.
