At this point I'm actually curious about the mass of the lorry.

I wonder if we could estimate the mass of a lorry, 2.5 meters wide, 20 m long, 46 billion light years tall. Let's assume it's filled with jars of peanut butter.

At that size, it could well be the most massive object in the universe.

Now that I think about it, it could also be too tall, possibly a tipping hazard around turns.

That truck tipping over could wipe out every lifeform on the planet with nut allergies.

The sheer mass of Skippy would become a fully functional ecological system of its own before cleanup was finished.

I mean, it has the potential to wipe out all life even without nut allergies. I for one have an allergy to things falling from the sky at c fractional speeds.

Take a Claritin, you'll get over it
