Do we lose heat back to the universe to keep our heat balance here on earth?

Does the heat get converted into some other form as predicted by Einstein’s equation (i.e. into mass for example)?

If we do not lose heat back to the universe, and if the heat is not converted into some other form, could that probably explain, partially, Global Warming?

If it keeps getting converted to some form like “mass”, could we say that the earth is “growing” i.e. it is becoming bigger and/or heavier (however small this growth rate might be)?

i, personally, think that time has umimagniably small particles. Each second, a particle disappears and another appears right after it. Each particle that dies marks one second. And each time a particle dies, space moves, so that is why we see space and look at it over time. Each second that passes in this space, one particle dies and another one reborns. And each particle is connected to something. So, for example, as I move my fingers around the keyboard to type and time passes, my fingers move to show time because each second that my finger moves, a particle of time dies and another reborns.
so, time particles effect the movement of space, and this way, we see time pass by looking at space move by the efects of the particles.

Five liters (5000 cm3) of oil is spilled onto a smooth lake. If the oil spreads out uniformly until it makes a circular oil slick just one molecule thick, with adjacent molecules just touching, estimate the diameter of the oil slick. Assume the oil molecules have a diameter of 2 10-10 m.

Answer should be in meters. Please explain results.
