The heat death of universe | Entropy | Science Phenomena

Hi STEEMIANS,
As we know, we can't create energy. We can just convert one type of energy to another. But the problem occurs when it comes to thermodynamics. We can't easily convert heat energy to other energy. But we can easily convert all other energy to heat energy. So, if we convert all the energies to heat energy, what will happen ? At that time, we can't get any kinda' energy. Cause that time entropy is in highest. That is the heat death of universe. Wikipedia says," The heat death of the universe is a plausible ultimate fate of the universe in which the universe has diminished to a state of no thermodynamic free energy and therefore can no longer sustain processes that increase entropy."
A joke:
Mom: Son, why you sleep all day long. Can't you work?
Son: No, mom. I can't. Cause my entropy is in highest. :D
Thank you.
