Let's annoy everyone with physics

How can this be done if you want to annoy everyone like a real physicist? The easiest way to do this is to insist on correcting the mistakes of others when they make little difference. Then, like the real physicist, they learn some tricks to annoy everyone and make mistakes in some general information.

.. .. .. .. .. ...

۔ The earth revolves around the sun.

no. The earth and the sun revolve around their common center of mass. The only thing is that the location of this center of mass is very close to the center of the sun because the sun has much more mass than the earth. And that's why it feels like the earth revolves around the sun.

(But if we have to be more precise, then this is also not entirely correct. Because Earth is not the only planet in the solar system, it is more complex than that).

...

۔ The speed of light is constant.

no. The speed of light is constant in space. When it travels in a medium, the speed decreases, depending on the properties of the medium. In space this speed is 299,792,458 meters per second, while in air it decreases to 299,705,544 meters per second. 228,849,205 meters per second in water.

And the speed of light in any medium is not independent of the observer as it is in a vacuum. In fact, the relative velocity of the medium also comes here compared to the Observer.

The speed of light in a medium can also depend on the polarization of light and the dispersion of color.

۔ Gravitational waves are waves that form in space-time.

Gravitational waves are periodic oscillations in gas or fluid in which gravity waves are a restoring force. Waves or some kind of cloud are examples of gravitational waves.

Spacetime waves are called gravitational waves, not gravitational waves.

۔ The earth is round

No, the earth is almost round. It is slightly larger in diameter than the poles at the equator. This is because it rotates around its axis and the centrifugal force is stronger in the parts that are farther away from its axis of rotation. Over time, this has resulted in an outward rise in the equator. This is a very small difference and the earth is very precisely round. but still ... This is the difference when it comes to annoying someone. We will insist that the earth is not a sphere but an oblate spheroid.

۔ Quantum mechanics is just a theory of small things.

Quantum mechanics applies to everything, no matter what its size. It's just that the effect on the big things is so small that it is no longer visible.

...

۔ I have lost weight.

Weight is a force that depends on the gravitational force of the planet you are on. And this is a vector. That means it has a direction. What you have reduced is mass.

...

۔ Light is both a particle and a wave.

No, it's not both. Like anything else, light is defined by the wave function in quantum mechanics. A wave function is a mathematical object that can have a very sharp focus (in which it looks like a particle) and can also have a spread (in which it looks like a wave). But it is actually a quantum object in which you can calculate the probability of measuring. And this is our best ever knowledge of "what is light."

...

۔ The sun is eight light minutes away from the earth.

This is only true in a special coordinate system in which the land is rested. If you are moving much faster than the Earth and use a coordinate system that is at rest compared to this high speed movement, then the distance between the Earth and the Sun will be different and this will be due to lorentz contraction. It will take less time for sunlight to reach the earth at a short distance.

۔ The water looks blue because it is a reflection of the sky.

The water is blue. Really If you look at the electromagnetic radiation in the visual spectrum that is absorbed by water, you will notice that it contains a dip of blue color. This means that water absorbs less blue than any other visible color. So this color will reach the eye and the water will look blue. But when you notice the water, it looks mostly transparent. This is because it absorbs very little of the visible light and being light blue is a very weak effect. The second is that this feature is for pure water. Seawater contains other minerals, salt and soil. If the water in the ocean looks blue, then the reflection of the sky over the water's own color is the reason why it is blue.

...

۔ The gravitational force in black holes is very strong.

A black hole with a mass M has the same gravitational force as any other body with the same mass. And that's it. It doesn't matter if it is a black hole or some other object.

If you remember Newton's law of gravity, the dependence of the gravitational force on a body's distance is according to Inverse Square. That is, if the distance is half, the force will be four times greater. The difference between a black hole and a star is that if you fall into a star, you will burn to ashes as you get closer. In the black hole you will keep moving towards its center. It will cross the horizon and the gravitational force will increase. Theoretically, it would reach infinity.

Hopefully, equipped with such information, you will be able to become very popular in your circle of friends by getting others to correct you in common conversation like an expert physicist.
