NASA can’t figure out how to make a rocket go faster than a measly 0.03% of the speed of light. This is a real problem for international space travel. So, here’s my plan.
Step 1: Establish a Mars colony.
Step 2: Have the colonists order a pizza with the “30 minutes or it’s free” deal.
Light takes 20 minutes to travel from Earth to Mars. If the pizza place doesn’t want to lose business, it will create a rocket that can travel at 2/3 the speed of light in order to make it on time. Also, the pizza place will get even more business by being the first restaurant to give pizza to Mars.
TL:DR NASA sucks, let the market create a faster rocket.
