Can energy exist without motion?
Most people seem to say that objects at rest are energy, as shown by the mass-energy equivalence principle, so energy can exist without motion.This is a common belief that is unfortunately not true.While [math]E=mc^{2}[/math] does calculate the energy of an object at rest, it's really a calculation of the objects internal energy which is caused by particles in motion.And really, when Einstein defined his famous equation, he said that the energy that radiates from an object decreases its mass by [math]\frac{E}{c^{2}}[/math] or as he wrote it, [math]\frac{L}{c^{2}}[/math]. With a small amount of math that equation is translated to [math]E=mc^{2}[/math].So no, there is no energy without motion. All types of energy, whether it be thermal energy, electrical energy, radiant energy,…etc. are due to kinetic energy. They all have energy because of the motion of particles.
Can energy exist without matter?
Any matter has always some amount of energy with it. For e.g. if we take any system containing gas then it always has some internal energy. Even at absolute zero temperature there is some small energy left what we call as "ZERO POINT ENERGY". So if you have a matter then it always has some energy.But matter is something which occupies space or has some volume or so mass also. If we take the light or any electromagnetic radiation, then it is made of photons which are massless. But of course it has some energy given by E=hf.However both matter and energy are inter-convertible. So pure energy can be converted into matter and matter may be converted into energy.For e.g. 1. Nuclear fusion and fission process shows conversion of mass (matter) into energy.2. The decay of gamma ray (ENERGY) into a pair of electron and positron (MATTER) is a prominent example of conversion of energy into matter.
Does energy exist without matter? Can energy be moved from place to place without matter?
Energy is matter and matter is energy it’s called unsurprisingly matter-energy. Einstein's famous equation e=mc2 expressed this beautifully.So yes energy can exist without matter. In fact current theories hypothesise that due to entropy all matter will eventually revert to a sea of uniform energy. A pretty unexciting end to a very dramatic beginning!And yes, energy can indeed be moved place to place without matter and thank goodness or we wouldn't be here! The sun is constantly emitting vast quantities of radiation and light energy that travels though empty space (no matter). Enough energy to support almost every form of life on earth.
Can there be energy without matter?
This is an interesting question.When an atomic bomb explodes, there is a lot of energy is released. That energy is in the form of potential or kinetic energy of photons and other particles. From that “reality” point of view, energy exists for and from matter.Cosmologists have found that our observable Universe is expanding. This expansion implies some Dark Energy, which is in the form of any matter.Matter exists in the form of some particles. From a quantum field theory perspective, a particle is an excitation of some fields, which is a manifestation of energy. From that point of view, energy exists irrespective of matter, and a matter particle is formed due to a “consolidation” of some energy.
Is there a place in the universe where time doesn't exist?
Yes, we can have no time anywhere we want. But the thing is, we have to travel at the velocity of light. Actually, according to special theory of Relativity by Einstein, space and time are not absolute. They are just relative to the observer. If 2 observers move with different velocities, their observations of time is different from each other. But, suppose, you travel at a speed of light, you feel no time. Your entire journey from one end of the Universe to the other will take place in just a SINGLE instant!! There's no time!!Unfortunately, you can NOT travel at the speed of light. Because, only massless particles travel at that speed. So, let's start dieting to become Zero Mass :pAlso, when you are inside a black hole. The huge gravity created by the black hole slows down the time. Suppose your friend is going to enter a black hole, s/he appears to slow down to you(you are far away from it) as he moves closer to the black hole and the time comes to a stand still once he enters the event horizon(the entrance for the Black Hole).Reference: How is time changed inside a black hole? - Sky & Telescope
How is time an illusion? How does linear time not exist? Many scientists including Einstein are wrong. What happens if you leave a fruit outside for 2 weeks? Will nothing happen then?
Imagine that all the clocks are lifted from the Earth. And then imagine that all the people disappear, too. It’s quiet. The sun rises and the sun sets. The sun rises and the sun sets.Leaving aside the question of whether the Earth exists without humans, we can say that time is an illusion because it’s a construct of the ego, something created by the human mind to make keeping track of stuff easier. Time allows the ego to feel like it’s in control; we’ve organized the chaos, we’ve got this. But what this is is really just a singular experience, where Change is the constant. We interpret the change as growing and aging and the progression of linear time, but those are the meanings that we’ve given to it, they’re not things that actually exist as a thing or occur in fact; they’re just imagined or supposed.(In most cases, the fruit seems to change. In some cases, the fruit doesn’t seem to change.)
