Can entropy be created or destroyed?

Can entropy be created or destroyed?

Entropy is not a conserved quantity. It can be created. In every irreversible cyclic process it gets created. However, entropy cannot be destroyed.

Is it true that matter can neither be created nor destroyed?

The Law of Conservation of Mass The same amount of matter exists before and after the change”none is created or destroyed. This concept is called the Law of Conservation of Mass. In a physical change, a substance’s physical properties may change, but its chemical makeup does not.

Which can neither be created nor be destroyed?

The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. In other words, energy cannot be created or destroyed.

Who said matter can neither be created nor destroyed?

Antoine LavoisierA

Can an atom be destroyed?

All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms cannot be created or destroyed. The atom is the smallest unit of matter that can take part in a chemical reaction.

Can light be destroyed?

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. If you meant destroying energy that photons possess, no you can’t destroy it. In the above example the energy is just converted into heating water.

Can light travel forever?

As long as it doesn’t get absorbed by something, then yes, light will continue to travel indefinitely. However, due to the expansion of the universe that light wave will get stretched out along with the space it travels through, becoming lower in frequency and energy.

Is darkness a form of light?

So, although an object may appear dark, it is likely bright at a frequency that humans cannot perceive.” I like “darkness is the absence of light.” Using that definition, then the answer has to be “no, because dark objects do not emit visible light.”

Why does light travel so fast?

According to Einstein’s general theory of relativity, as an object moves faster, its mass increases, while its length contracts. At the speed of light, such an object has an infinite mass, while its length is 0 ” an impossibility. Thus, no object can reach the speed of light, the theory goes.

Is light faster than darkness?

Most of us already know that darkness is the absence of light, and that light travels at the fastest speed possible for a physical object. In this respect, darkness has the same speed as light.

Are Tachyons real?

Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light ‘quasiparticles’ moving through laser-like media.

Who found Tachyon?

Gerald Feinberg

What if Tachyons were real?

Tachyons might create such a glow in empty space. Tachyons are hypothetical particles that travel faster than the speed of light in a vacuum. If tachyons were electrically charged, they could produce Cherenkov radiation in empty space. Or one might guess that tachyons should be electrically neutral, like neutrinos.

Can a tachyon escape a black hole?

And the answer to your question for this kind of tachyon is that it cannot escape a black hole. Since the disturbance of a localized tachyon cannot spread faster than c, it therefore cannot escape the inside of a black hole’s event horizon.

Could a human survive a black hole?

Even light, the fastest-moving thing in our universe, cannot escape “ hence the term black hole. Thus, the person would pass through the event horizon unaffected, not be stretched into a long, thin noodle, survive and float painlessly past the black hole’s horizon.

Will our Sun become a black hole?

No. Stars like the Sun just aren’t massive enough to become black holes. Instead, in several billion years, the Sun will cast off its outer layers, and its core will form a white dwarf – a dense ball of carbon and oxygen that no longer produces nuclear energy, but that shines because it is very hot.

Can anything escape from a black hole?

No light of any kind, including X-rays, can escape from inside the event horizon of a black hole, the region beyond which there is no return. NASA’s telescopes that study black holes are looking at the surrounding environments of the black holes, where there is material very close to the event horizon.

Where do things go in a black hole?

It is thought that the matter that goes into a black hole gets crushed into a tiny point at the center called a “singularity”. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.

Why can light escape a black hole?

Since all future lies within the event horizon, photons are trapped inside the black hole. Even though photons have no mass, they are still affected by gravity. The escape velocity from within a black hole’s event horizon is faster than the speed of light, hence light cannot go at that speed and thus cannot escape.

What happens if you get stuck in a black hole?

No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you’re done. There’s no getting out. Even if you were still alive, you’d have to travel faster than the speed of light in order to escape.

What is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small ” in fact, zero ” amount of space. The result is a powerful gravitational pull, from which not even light can escape ” and, therefore, we have no information or insight as to what life is like inside.

Do wormholes exist?

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.

Does space have an end?

No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.

Is there any white hole in universe?

Why white holes don’t exist While general relativity describes white holes in theory, no one knows how one might actually form. A black hole cordons off its bit of space when a star collapses into a tiny volume, but playing this video backwards doesn’t make physical sense.

What happens when two black holes collide?

When two black holes spiral around each other and ultimately collide, they send out gravitational waves – ripples in space and time that can be detected with extremely sensitive instruments on Earth. If confirmed, it would be the first known light flare from a pair of colliding black holes.

Are there other universes?

There is not one universe”there is a multiverse. In Scientific American articles and books such as Brian Greene’s The Hidden Reality, leading scientists have spoken of a super-Copernican revolution.

What was before the universe?

It’s possible that before the Big Bang, the universe was an infinite stretch of an ultrahot, dense material, persisting in a steady state until, for some reason, the Big Bang occured. This extra-dense universe may have been governed by quantum mechanics, the physics of the extremely small scale, Carroll said.
