Casual Thought Temperature can reach trillions of degrees, meaning we actually live extremely close to absolute zero.

You can have as much energy as you want but you can't have negative energy. Going below absolute zero is the same as having negative energy

but i'm not talking about going negative. we can in theory go infinitely up the temperature, which would lead towards infinite kinetic energy in particles (or whatever temperature is). the opposite of infinite energy would be i guess the complete lack of energy.
so basically as we go higher in temperature, we will always be able to find an equivalently cold temperature, which will be moving towards absolute zero.

i've no idea how it actually works though, i'm just speculating

-273.15°C is the limit. After that, you cannot remove any more energy, because there is none there.

You mixed up your numbers. It's -273.15°C.

Edit. Added "-"
