💡Did you know this?
✨You may hear stars referred to as “eternal,” but in fact no star can last forever. Since the “business” of stars is making energy, and energy production requires some sort of fuel to be used up, eventually all stars run out of fuel.
✨ This news should not cause you to panic, though, because our Sun still has at least 5 or 6 billion years to go.
✨Ultimately, the Sun and all stars will die, and it is in their death throes that some of the most intriguing and important processes of the universe are revealed. For example, we now know that many of the atoms in our bodies were once inside stars.
✨These stars exploded at the ends of their lives, recycling their material back into the reservoir of the Galaxy. In this sense, all of us are literally made of recycled “star dust.”

A nebula has a density generally from 100 to 10,000 particles per cm³. The Earth's atmosphere, by comparison, contains 2.5×10¹⁹ particles per cm³. Although nebulae are denser than the space surrounding them, most of them are far less dense than any vacuum created on Earth. Just one portion of a nebula the size of Earth would weigh only a few kilograms.

Congratulations !So as your vote from now on for the next three days I will be posting articles on psychokinesis,Invisibility, phasers teleportation,telepathy ,Robots programmed by Artificial intelligence, spaceships,starships,antimatter and anti universes,and finally time travel machine.
Psychokinesis will be the first .Here it is👇
Psychokinesis will be the first .Here it is👇
👉Psychokinesis, also called telekinesis, in parapsychology, the action of mind on matter, in which objects are supposedly caused to move or change as a result of mental concentration upon them. The physical nature of psychokinetic effects contrasts with the cognitive quality of extrasensory perception (ESP), the other major grouping of parapsychological phenomena. Claimed effects of psychokinesis include levitation and metal bending; such displays are common, though fraudulent, in theatrical magic.

✨Exploration of the new scientific discoveries is transforming the world to the great civilization equipped with the advanced technologies ,may be alot of you amazed and consider this as that can't be ever done.
✨A few of you already heard this in some incident and already adapted to it , because you read different books. you may have heard a saying "Today's scientific fictions are tomorrow's scientific facts".
✨Why do you think this is obvious and we see them happening in real ? Marvel movies are mostly science based movies and technologies we see in those movies are scientific hypothesis expected to happen the coming 2 or 3 generations.
✨generation can be described as, "the average period, generally considered to be about 20–30 years, during which children are born and grow up, become adults, and begin to have children. From this we can understood that these technologies can be realized in 90 years or below that .
✨One of these technologies expected to be realistic is invisibility.Read article below👇

What is invisibility ?
⚛Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible (literally, "not visible"). The phenomenon is studied by physics and perceptual psychology.
⚛Since objects can be seen by light in the visible spectrum from a source reflecting off their surfaces and hitting the viewer's eye, the most natural form of invisibility (whether real or fictional) is an object that neither reflects nor absorbs light (that is, it allows light to pass through it).
⚛ This is known as transparency, and is seen in many naturally occurring materials (although no naturally occurring material is 100% transparent).
⚛Invisibility perception depends on several optical and visual factors.
For example, invisibility depends on the eyes of the observer and/or the instruments used. Thus an object can be classified as "invisible to" a person, animal, instrument, etc.
⚛In research onsensorial perception it has been shown that invisibility is perceived in cycles.
⚛Invisibility is often considered to be the supreme form of camouflage, as it does not reveal to the viewer any kind of vital signs, visual effects, or any frequencies of the electromagnetic spectrum detectable to the human eye, instead making use of radio, infrared or ultraviolet
wavelengths.
⚛In illusion optics, invisibility is a special case of illusion effects: the illusion of free space.

Phasers
👌phaser is an electronic sound processor used to filter a signal by creating a series of peaks and troughs in the frequency spectrum.
👌The position of the peaks and troughs of the waveform being affected is typically modulated by an internal low-frequency oscillator so that they vary over time, creating a sweeping effect.
👌Phasers are often used to give a "synthesized" or electronic effect to natural sounds, such as human speech. The voice of C-3PO from Star Wars was created by taking the actor's voice and treating it with a phaser.

⚛Teleportation is the hypothetical transfer of matter or energy from one point to another without traversing the physical space between them.
⚛It is a common subject in science fiction literature and in other popular culture. Teleportation is often paired with time travel, being that the travelling between the two points takes an unknown period of time, sometimes being immediate.
⚛There is no known physical mechanism that would allow for teleportation.
⚛Frequently appearing scientific papers and media articles with the term teleportation typically report on so-called "quantum teleportation", a scheme for information transfer which, due to the no-communication theorem, still would not allow for faster-than-light communication.

✨A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics.

Well guys ,for about a week we have been posting articles of the hypothetical technologies , which are waiting for the theory that unifies the four fundamental forces,and starting from now we will start posting articles by the question from you, our subscribers .we will inform you soon topic to chose on .
⚛Hawking radiation is thermal radiation that is theorized to be released near a black hole's event horizon because of relativistic quantum effects.
⚛It is named after the physicist Stephen Hawking, who developed a theoretical argument for its existence in 1974.
⚛Hawking radiation is a purely kinematic effect that is generic to Lorentzian geometries containing event horizons or local apparent horizons.
⚛Hawking radiation reduces the mass and rotational energy of black holes and is therefore also theorized to cause black hole evaporation.
⚛ Because of this, black holes that do not gain mass through other means are expected to shrink and ultimately vanish. For all except the smallest black holes, this would happen extremely slowly.
⚛ The radiation temperature is inversely proportional to the black hole's mass, so micro black holes are predicted to be larger emitters of radiation than larger black holes and should dissipate faster.

Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe.
👉Its presence is implied in a variety of astrophysical observations, including gravitational effects that cannot be explained by accepted theories of gravity unless more matter is present than can be seen. For this reason, most experts think that dark matter is abundant in the universe and that it has had a strong influence on its structure and evolution.
👉Dark matter is called dark because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect or emit electromagnetic radiation, and is therefore difficult to detect.

Sidereal day
👉The sidereal day is the time it takes for the Earth to complete one rotation about its axis with respect to the ‘fixed’ stars. By fixed, we mean that we treat the stars as if they were attached to an imaginary celestial sphere at a very large distance from the Earth.
👉A measurement of the sidereal day is made by noting the time at which a particular star passes the celestial meridian (i.e. directly overhead) on two sucussive nights. On Earth, a sidereal day lasts for 23 hours 56 minutes 4.091 seconds, which is slightly shorter than the solar day measured from noon to noon.
👉Our usual definition of an Earth day is 24 hours, so the sidereal day is 4 minutes faster. This means that a particular star will rise 4 minutes earlier every night, and is the reason why different constellations are only visible at specific times of the year.
