• If you assume the universe has a "beginning" and therefore there is no such thing as "infinity ago", are there any sneaky consequences that emerge from that that can confirm/refute current models? I can only say: smells like a thing.
• What if you pretended that "cold" was a property that some particle had? So you can have a concentrated mass of "cold" particles and when they come in contact with other particles, they transmit a small amount of their "cold".

"No such thing" is no excuse.
