What is energy?

[isawit]

nowadays everything energy, everything quantum.

do you really know what is energy? not even einstein. he said he knows not what are light quanta.

what is ENERGY?

coal? fuel? oxygen? wind? sunlight? any matters?

NO. the matter is not energy. the matter is the carrier/source/container of energy.

a rock at rest only has its thermal energy.

if you threw it away, your hand put a force on the rock pushing it moving at a speed v, the moving rock will have 1/2mvv energy added on it. we call it kinetic energy.

if the flying rock hits a wall, that energy becomes the impact force that hits the wall, makes atoms on the wall vibrate faster/hotter, atoms thermal energy.

so, energy is nothing but vibrating force/moving force.

energy is always vibrating/moving, within and between matters. the matter is always moving/vibrating due to the existence of energy.

nothing is ever at rest, keep moving, changing, involving, reforming, transforming.

somehow, LIFE woke up?

"do you really know what is energy?"

It is the difference.what is indifferent:
space-time.all the rest is difference

"nothing is ever at rest"

Time-space is at rest.how old is reality

[profitis]

"nothing is ever at rest"

Space-time is at rest.how big is reality

[isawit]

time space is a mistake

what is time? the reading on the clock?

is time has mass? charge? volume? how gravity affects time?

einstein farted, people love the smell. that's the deal.
