The nature of light.
A photon has energy and momentum (weight) but no mass . It is obvious that light is vibrations of some medium (ether). This environment cannot but have resistance, damping or absorbing light vibrations with time and distance. I will describe the essence in simple words so as not to complicate and not drag out the explanation.
1) Water waves. They spread longer (in time) than sound, but at a shorter distance (at a lower speed). Distribution medium: water.
2) Sound waves. The lifetime of sound waves is shorter than that of water waves, but the speed (and distance) is greater. Distribution medium: atmosphere (gas).
3) Light waves. By analogy, the lifetime of light waves should be much shorter than the lifetime of sound waves, but since the speed of light is about 300,000 km / s, the propagation distance is greater. Distribution medium: ether.
(a schematic representation of a photon - a conventional unit of oscillation (wave) of the ether) Image text translation: The movement of one light wave (photon) from the source to complete attenuation and / or absorption by the medium (ether).
At the beginning of the 20th century, scientists rejected the completely plausible hypothesis of the Tired Light, began to carry out fortune-telling by redshifts of the spectrum (like on coffee grounds, only by the emission spectra), and billions of light years, black holes, dark energies, and distant, distant galaxies rushed.
A photon cannot exist not only for years, but even for minutes. Example. Standing in the lake. You throw a stone. First you hear the sound, later the waves come. Waves on water, sound waves in a gaseous medium and light waves in ether are phenomena of the same nature, but of different orders due to the environment. If waves on water “live” for minutes, and sound waves in a gaseous medium “live” for seconds, then light waves in their medium (ether) “live” for a fraction of a second. All this depends on the power of the source of wave oscillations, so it can be assumed that light waves from the Sun can exist for several seconds, but not more (not minutes, and even less years).
Even if in the space environment (vacuum) there is no resistance, there is no heat exchange, then the distance is overcome (volume expansion with distance), which cannot occur absolutely without energy consumption. In addition, the space of the cosmic vacuum cannot be absolutely empty. There cannot but be certain, albeit minimal, resistance and heat transfer. Light years and 8 light minutes from Sun to Earth are physically impossible.
Again. Attentively. This is very important to understand. Overcoming distance in any environment, that is, regardless of the environment, cannot occur without energy consumption (or with zero energy consumption). Since a photon has a very low energy charge, and a very high speed of movement, and no medium (including space) can have absolutely zero resistance, then, accordingly, the lifetime (life) of one photon (wave oscillation of the medium - ether) is very short, not exceeding at least one minute.
Definition. The lifetime of a unit of wave oscillations (one wave) is inversely proportional to the speed of their propagation (or directly proportional to the inertia of the medium) and is directly proportional to the power of their source.
Since the ether is not scientifically recognized, it turns out that a photon is a conventional unit of wave oscillations of an incomprehensible medium? A photon has weight (energy and momentum), but no mass - it is obvious that this is an oscillation (wave) of some medium (ether).
If the distance from the Earth to the Sun were 150,000,000 km, that is, 8 light minutes, then the STEREO Ahead and STEREO Behind spacecraft would simply be impossible to control, and it would be impossible to receive any data from them. For example. STEREO A (itself being in constant motion in orbit) sends a signal to the Earth that flies in space for 8 minutes, and during this time the Earth moves in orbit for 8 minutes. * 60 sec. * 30 km / s. = 14 400 km. Not to mention the enormous degree of radio signal scattering over distances of tens of millions of kilometers or several light minutes.
(animation of the movement of STEREO spacecrafts around the Sun)
There is a photo animation on the web that shows a solar flare in the direction of one of these satellites. The STEREO Ahead spacecraft supposedly moves along the Earth's orbit, that is, at the same distance from the Sun as the Earth. This is an animation of STEREO A photos from July 23, 2012.
The solar flare flew exactly in the direction of STEREO A. It began at almost exactly 03:00 (UTC), and the first visible particles of coronal matter (white ripples in the animation) flew to STEREO A at about 07:00 (UTC). If the distance from the Sun to the Earth's orbit (on which the STEREO spacecraft are located) were 150,000,000 km, as is officially believed, then the speed of coronal material particles would be 150,000,000 km. / 4 hours / 60 minutes / 60 seconds = about 10,000 km / s. - this is 3% of the speed of light, which is hardly physically possible.
The solar wind is a stream of ionized particles (mainly helium-hydrogen plasma) flowing out from the solar corona at a speed of 300-1200 km / s into the surrounding space.
In addition, it is generally known that the flow of coronal matter from a solar flare reaches the Earth's orbit (in which the STEREO spacecraft are supposedly located) in an average of 150,000,000 km. / 750 km / s / 60 sec. / 60 min. / 24 hours = ~ 2.5 - 3 days. But in fact, the animation of the photos turns out to be 07:00 (UTC) - 03:00 (UTC) = 4 hours. And it turns out this way because spacecraft are orbiting Venus in the Solar System (Universe) with approximately the same parameters as in the schematic image below.
(ProtoEarth, Sun, Moon, Mercury, Venus, Mars; common center of mass between Earth and Sun; distance to the Moon is about 100 000 km., distance to the Sun is about 300 000 km.; Oort Cloud is the border of the Universe where all the "stars" and "galaxies" located; the diameter of the Universe does not exceed one light minute)
The rotation of the Earth and the Sun, as two commensurate objects, around a common center of mass, is difficult to describe in words and to draw schematically - therefore, I end the article with a corresponding animation, in which the size ratios are close to reality (the Earth is larger, the Sun is smaller).
