  • How can energy be created and destroyed?

  • As we know through thermodynamics, energy cannot be created nor destroyed. It simply changes states. The total amount of energy in an isolated system does not, cannot, change. And thanks to Einstein, we also know that matter and energy are two rungs on the same ladder. The universe as a whole is closed.

  • Is it possible to destroy light?

  • YES, light can be destroyed , but its energy cannot be destroyed . when the energy in the light changes to another form (like heat)..you can say that light is destroyed. 鈥?If you meant destroying energy that photons possess, no you can鈥檛 destroy it. In the above example the energy is just converted into heating water. Is energy ever lost?

  • Can anything be created or destroyed in the universe?

  • Can anything be created or destroyed? There is a scientific law called the Law of Conservation of Mass, discovered by Antoine Lavoisier in 1785. In its most compact form, it states: matter is neither created nor destroyed. 鈥?the total amount of mass and energy in the universe is constant. Are humans just energy?

  • What happens to energy when we die?

  • We can gain energy (again, through chemical processes), and we can lose it (by expelling waste or emitting heat). In death, the collection of atoms of which you are composed (a universe within the universe) are repurposed. Those atoms and that energy, which originated during the Big Bang, will always be around.
