Superluminal (Fast from Light) Movement

Is the speed of light an obstacle for us or can we exceed the speed of light? Or will our technology enable us to reach the speed of light one day? While such questions confuse us, let's define a speed that was introduced in the 1970s and that few people know.
Superluminal movement; are movements at speeds greater than the speed of light. According to the theory of relativity, nothing can move faster than light, but it seems possible for different structures in the universe. So how?

While astronomers were trying to understand the quasars, they discovered a new kind of structure. These objects, called Blazars, had properties similar to a star and quasar.

Blazars are giant elliptical galaxies with active galactic nuclei and have a large redshift spectrum, just like quasars. The blazars, which have a high energy structure, are extremely variable. Radiation power was found to be very variable by looking at the jets coming towards us with radio astronomy observations. While its radiation is 30% in one day, it can change as much as a 100% multiplier in a few months.
The jets in the blazers are a dual source of radio. The weak radio wave emission around the bright active core is indicative of this. This situation is supported by the observations of the movement at speeds greater than the speed of light observed in some quasars, that is, the superluminal movement.
Blazar jets appear very close to the speed of light and at a very small angle against the observer. The visual above shows a simple explanation in movements that are faster than the speed of light. Let the source's view of the Earth be an angle of degree. Let's assume that the source speed is also v. At the first point, the source releases a photon that gives us an angle θ of v speed. Let's say that after its movement for the period of t, it transmits another photon from position 2. The actual distance between the two locations is ∆t * v. The distance between the two photons is v * ∆t * cos θ. So the first photon comes as early as v * ∆t * cos θ. Since the projection of the sky is in other words, its horizontal motion is d, we can theoretically demonstrate that when we take two photons, the period moves at a speed d / v * ∆t * cos θ times the source of light.
Suppose that the speed of the source is 0.8 c, our perspective is 30 degrees. Let's assume that a photon is released from point A and that this photo travels for 5 light days. Let's assume that it emits another photon from point B, the second location of the source. The actual distance traveled by the source between the two locations is: 5 * 0.8 = 4 light days. Therefore, the source moves towards us along the direction of gaze on 3.46 light days. 1st photon is 5-3.46 = 1.54 light days ahead of 2nd photon. If we consider the horizontal movement (projection) as 2 light days, we conclude that the source is moving 2 / 1.54 = 1.3 times faster than the speed of light. This situation can be proved theoretically and geometrically, and evidence has been obtained in the observations made.
Superluminal motion observed in the M87 jet

With the photos provided by the Hubble Space Telescope until 1999, the speed of the eruption in M87 was measured to be five or six times higher than the speed of light. This eruption most likely consists of a substance thrown 5000 light years from the core of the M87 under the influence of a super-massive black hole.
Superluminal motion has been taken as evidence against quasars with cosmological distances. Although several astrophysicists are still assertive in this view, most consider speeds greater than the speed of light to be included in physics incompatible with optical illusions and the special theory of relativity.
