The problem of two photons

The problem of two photons

Nothing else can travel faster than light. And only particles that can reach that speed in the straight universe are photons. So when we are thinking about the case where two photons are going to different ways, we must realize that if we would sit on another photon, we cannot get any observation from a photon that travels away from us.

Because the speed of light is cosmic constant we would not get the observations of the photons that are coming after us either. So as you see there are two ways to say the same thing. And the answer depends on the way how we describe the edge of the universe.

If we want to answer the question: "Does the universe expand faster than light? " We should describe the edge of the universe.

The edge of the universe can describe as:

1) The edge of the most out gas atoms in the universe, when the speed of expanding follows the Hubble law.

2) The point where the first photons that are left from the Big Bang are reached.

So if we are using photons as describing the edge of the universe the speed of expansion is the speed of light. And the speed of photons that are traveling in the opposite direction is 2X the speed of photons because they are traveling in opposite directions. But the photons themselves cannot cross the speed of light.

The answer is yes and no at the same time. If we are thinking that the edge of the universe is at the point that the first photons that are released in the Big Bang are reaching we might think that the escaping speed between those photons is 2X the speed of the light. But the fact is that the photon itself doesn't cross the speed of light. We can answer the question about the speed of the expanding universe in two ways.

We can say that the expanding speed of the universe is the Hubble Constant is now 69.8+(1.9−1.9) (km/s)/Mpc ((m/s)/Megaparsec), what is the speed of the gas. Or the universe can expand with the speed of light in every direction if we are thinking that the edge of the universe is the point, where the first photons from the Big Bang have reach. So the diverge speed of photons that are traveling to opposite directions is 2X speed of photons. But they cannot cross that speed.

When robots are laughing and crying.

When robots are laughing and crying. Does the AI have feelings? Does the AI have feelings? Or can it be emphatic? The fact is this program code that controls the AI determines if it can give empathic reactions. The problem with the human nervous system is that we don't make a difference in the writing of empathic letters or telling empathic stories human or AI. Our nervous system is not adapted to AI yet. And that's why we cannot separate text written by AI from text that made by humans. What does somebody make with AI that can emulate feelings? The fact is that the cyborgs are useful tools for infiltration operations. The human-size robots can have WLAN/6G connections with the central computers. Or they can form a neural network that shares information between all group members. The robots can also act as walking neural network-based supercomputers. That can make complicated solutions. In those networks, each member shares information and their data-handling capacity all o

Earth 2.0 has been caused discussion about the possibility to find another civilization

Earth 2.0 has been caused discussion about the possibility to find another civilization The Earth 2.0 or officially Kepler-452b is locating extreme log distance from Earth(1). A new Earth-type planet has been found near the star, which is similar to our own Sun. The journey to that planet would take 1400 years, even if the spacecraft will reach the speed of the light. The planet has been found in the year 2008, but the confirmation of the existence of that planet has been taken time, but in 2015 the confirmation has been got, and Earth 2.0 has turned true. The mass of that planet is 1,9 times Earth and the temperature is excellent if we are thinking about liquid water, but the journey to that planet will take so long, that we cannot ever go in there by using regular rockets and technology. The thing is that this kind of planets are the most interesting if we are looking for the lifeforms, which are similar to us, and the problem with that kind of things is that the communicatio

Tunguska meteorite and the natural nuclear fission

Image I Tunguska meteorite and the natural nuclear fission 1) Tunguska UFO-theory Tunguska meteorite is the mystery, that has been solved once, but then the case has been open again because Lake Cheko was not suitable for an impact crater. That lake has been introducing as an impact crater of the Tunguska meteorite. But the problem is that the shape of that lake is like a swimming pool. And that means it cannot form by a meteorite. So the mystery remains. Meteorites can launch the natural nuclear fission if they hit the uranium ore, and transfer the impact energy to that ore. And is the thing that the famous "Tunguska" meteorite caused that kind of effect? There is also a theory that some "UFO" explode in that area, but the thing is that it is only theory, but interesting topics for some TV-series. So I will begin this text by handling that theory, which is one of the incredible and outstanding theories in the world. Officially there is no physical evidence of
