This paper presents the effect of gravity on the atomic level. Various research has been considered to find any variations in the effect of gravity at the atomic level and macroscopic level. The effect of gravity has been calculated for various planets. Consequently, suggestions have been made for the space equipment manufacturers to consider the variation in current density due to gravity for the planets.

Anything that has mass has gravity too. Objects with greater mass have greater gravity. With distance also, gravity gets weaker. Therefore, the smaller the bodies are, the greater their gravitational force is [1-5]. The gravity of Earth originates from all of its mass. All its mass makes the whole mass in the body a combined gravitational pull on. If we are on a planet with less mass than Earth, we’d be weighing less than here. Gravity is a fundamental force of Nature, one we Earthlings prefer to take for granted. And you can’t blame us. Having evolved in Earth’s climate throughout billions of years, we are used to living with the tug of a steady 1g (or 9.8m/s2). Yet gravity is a very tenuous and precious thing for those who have gone into space or set foot on the Moon [6]. Isaac Newton and Albert Einstein’s works dominate the development of the theory of gravity. Also, today, Newton’s classic gravitational force principle is adequate for even the most detailed applications. Einstein’s general relativity theory only forecasts minute quantitative deviations from the Newtonian principle except in a few special cases. The key importance of Einstein’s theory is his revolutionary philosophical break from classical thought and its consequences for the further development of physical thinking [7].
The launch of space vehicles and their scientific advances have resulted in major changes in gravity measurements around Earth, other planets, and the Moon and studies on the existence of gravity [8]. Newton believed that there is an irresistible force between all the huge bodies, one that does not involve interaction with the body and works at a distance. By referencing his law of inertia (bodies not exerted by force traveling at a constant speed in a straight line), Newton proposed that a force exerted by Earth on the Moon is required to hold it in a circular motion around Earth, rather than a straight-line shift. He discovered that, at long range, this force might be the same as the force in which Earth forces objects downward on its surface. Because once Newton revealed that perhaps the Moon’s acceleration seems to be 1/3,600 lower than that of the Earth’s surface, he directly linked the total 3,600 to just the square of the Earth’s radius [7,8]. In Newton’s laws, every slightest particle of matter gravitationally continues to attract almost every particle. On another grounds, he demonstrates that the allure of a finite body to spherical symmetry is the same as those of’s entire mass at the body’s center. Quite specifically, any body’s attraction at a reasonably high distance is identical to those from the entire mass at the center of the object [7,8]. In our interpretation of relativity, the German-American mathematician Albert Einstein gave the next development. His theory of general relativity demonstrated that gravity derives again from space-time curvature, implying that even rays of light that must obey this curvature are curved by extraordinarily large objects [9]. Einstein’s ideas have been used to argue on the Nature of black holes dark bodies of so much mass that even light cannot penetrate their surfaces. Newton’s universal gravitation law no longer correctly explains how objects travel around in the vicinity of a black hole, but instead, Einstein’s tensor field equations take precedence. According to Minute Physics, the application of Newton’s gravitational law to incredibly light objects, such as humans, cells, and atoms, remains something of an unstudied field.
Scientists believe that these bodies attract each other using the same gravitable laws as planets and stars, but it’s pretty hard to tell because gravity is so weak. Atoms could gravitationally pull each other at a rate of just one cubed over the distance rather than squared our intuitive tools have no reason to approach. Different secret facets of science could be accessible if we could only calculate the minute gravitational forces [9]. Other effects of Einstein’s relativity have since been identified by physicists over the past few years gravitational waves that exist as huge objects like neutron stars and black hole spin together. Since 2017 the LIGO opened a new world window with a very faint signal from the Laser Interferometer Gravitational-Wave Observatory [9-11]. Scientists today know about four forces objects which attract (or repel) one object to (or from) another. High force and low force work only within the atom centers.
The electromagnetic force governs hyper-charged objects (such as ions, protons, and shoes shuffling through a foggy carpet), and gravity regulates objects of mass [11]. The weakest of the universal forces is gravity. A bar magnet can electromagnetically pull up a paper clip around the piece of office furniture, resisting the tidal power of the entire Planet. Physicists have determined that gravity is 10^40 times slower than electromagnetism (that’s the number 1 accompanied by 40 zeros), according to PBS’ Nova [12]. This paper is structured in the following manner. The background and introduction have been described in sections 1. Section 2 discusses the gravity of other planets. Current density has been explained in sections 3. Section 4 describes the effect of gravity at the atomic level. Section 5 discusses the variations in current density at planets. Finally, section 6 concludes the paper.

Gravity on other Planets

Practically, gravity is reliant on mass, in which all objects are drawn to one another from stars, planets, and universes to photons and subatomic particles. This same gravitational force imposes changes according to the size, mass, and concentrations of the object. But then when it happens to come to today’s Solar System’s planets, which vary in size as well as mass, the force of gravity on about their surfaces varies significantly [1-4,12]. For instance, Earth’s gravity, as effectively noted, is equal to 9.80665m/ s² (or 32.174ft/s²). It means that an object should quicken towards the surface at a pace of around 9.8 meters per second if it is held over the ground and let go. This is the norm for estimating gravity on different planets, which is likewise communicated as a single g [12]. In light of their sizes and masses, the gravity on another planet is frequently communicated as far as g units, just as regarding the pace of free-fall increasing speed [12-14]. So, it will be seen precisely about the planets of our Solar System stack up regarding their gravity contrasted with Earth.

Effect of Gravity on Planet Mercury

Mercury has a mean span of around 2,440km and a mass of 3.30×1023kg. Mercury is roughly 0.383 occasions the size of Earth and just 0.055 as enormous. It makes Mercury the littlest and least Earth in the Solar System. Nonetheless, on account of its high thickness a strong 5.427g/cm3, which is simply marginally lower than Earth’s 5.514g/cm3. Mercury has a surface gravity of 3.7m/s², which is what could be compared to 0.38g [12].

Effect of gravity on the planet venus

In several ways Venus is identical to Mars, which is why it is sometimes referred to as “The Sister of Mars.” With an average radius of 4,6023108km2, a weight of 4,8675 about 1024kg, and even a permeability of 5,243g/cm3, Venus is comparable in size to 0,9499 Earths, 0,815 times as vast, and about 0,95 times porous. Therefore, it’s no wonder that Venus’ gravity is very close to that of Earth’s 8.87 m/s2, or 0.904g [12-15].

Effect of gravity on planet moon

This is one vast body where individuals have had the option to try out the effects of reduced gravity face to face. Computations dependent on its mean sweep (1737km), mass (7.3477x10²²kg), and thickness (3.3464g/cm³), and the missions directed by the Apollo space travelers, the surface gravity on the Moon has been estimated to be 1.62m/s2, or 0.1654g [1,12,15].

Effect of gravity on planet mars

In certain main ways, Mars is close to Earth too. But Mars is relatively small when it comes to dimensions, mass and density. Besides, its mean radius of 3,389km is equal to approximately 0.53 Earths, while its mass (6,4171 almost 1023kg) is just 0.107 Earths. In the meanwhile, the mass is around 0.71 Earths, coming in at a fairly respectable 3.93g/cm3. Of this cause, Mars has 0.38 times the Earth’s mass, which amounts to 3.711m/s2 [4,12,14].

Effect of gravity on planet Jupiter

Jupiter is the biggest and most Earth in the Solar System. Its mean span, at 69,911±6 km, makes it 10.97 the occasions the extent of Earth, whilst its mass (1.8986×1027kg) is what could be compared to 317.8 Earths. Be that as it may, being a gas goliath, Jupiter is normally less thick than Earth and other earthbound planets, with a mean thickness of 1.326 g/cm3. Also, being a gas mammoth, Jupiter doesn’t have a genuine surface. If one somehow happened to remain on it, they would just sink until they, in the long run, showed up at its (estimated) strong center. Therefore, Jupiter’s surface gravity (which is characterized as the power of gravity) is 24.79m/s, or 2.528g [6,12].

Effect of gravity on planet Saturn

Unlike Jupiter, Saturn is a massive gas giant that is far heavier and heavier than Mars, but much less dense. In brief, its mean radius is 58232±6km (9.13 Earths), its mass is 5.6846×1026kg (95.15 times the moon), and its density is 0.687g/cm3. As a result, the surface gravity is significantly greater than that of the Planet, which is 10.44m/s2 (or 1.065g)[12-15].

Effect of gravity on planet Uranus

At an estimated radius of 25,360km and a mass of 8,68×1025 kilograms, Uranus is almost four times the size of the Sun and 14,536 times the size of the Moon. Nevertheless, mostly as a gas giant, its density (1.27 g/cm3) is markedly smaller than that of the Earth. Therefore, the surface gravity (as estimated from its cloud tops) is slightly lower than that of Earth -8.69m/s2 or 0.886g [1-4], [12-15].

Gravity on Neptune

With a mean span of 24,622±19km and a mass of 1.0243×1026kg, Neptune is the fourth biggest Planet in the Solar System. Everything considered it is 3.86 occasions the size of Earth and multiple times as monstrous. However, being a gas monster, it has a low thickness of 1.638 g/cm3. The entirety of this works out to a surface gravity of 11.15m/s2 (or 1.14g), which again is estimated at Neptune’s cloud tops. Gravity runs the array here in the Solar System, extending from 0.38g on Mercury and Mars to an incredible 2.528 g on Jupiter’s mists. What’s more, on the Moon, were space explorers have wandered, it is a gentle 0.1654 g, which permitted from some pleasant investigations in near weightlessness! Understanding the impact of zero-gravity on the human body has been fundamental to space travel, particularly where long-length missions in the circle and to the International Space Station have been concerned. In the coming decades, realizing how to reproduce it will prove to be useful when we begin sending space travelers on profound space missions. What’s more, realizing exactly how solid it is on different planets will be fundamental to keep an eye on missions (and maybe even settlement) there. Given that humankind advanced in a 1g condition, knowing how we will get admission on planets that have just a small amount of the gravity could mean the contrast among life and passing [1-4,12-15].

Electric Current and Current Density

Current is generally considered as a progression of electrons. At the point when two closures of a battery are associated with one another by utilizing metal wire, electrons stream out of one finish of the battery, through the wire, and into the opposite finish of the battery. Current is typically consistent if its extent is steady, and its heading will consistently be the equivalent [16]. Current density is a lot of identified with electromagnetism. It is characterized as the measure of electric current moving through a unit estimation of the cross-sectional zone. Suppose there should be an incident of a consistent current that is coursing through a conductor, similar current moves through all the cross-segments of the conductor. This stream is the equivalent even though the crosssegments may vary in the zone. Electric flow is a naturally visible substance. We accept the electric current through a transmitter and not about electric current at a point. A relating infinitesimal, in the power field, its current density. Current density, in a conductor, can be characterized as the pace of stream of charge over any cross-segment of the conductor [16-19]. Current density alludes to the density of the current stream in some conductor. In the field of electromagnetism, Current Density and its estimation are significant. It is the proportion of the progression of electric charge in amperes per unit region of cross-segment, for example, m². This is a vector amount because of greatness. It is having the heading of the stream. An electrical current that moves through and has units of charge per unit time per unit zone. It is likewise estimated toward the path which is opposite to the progression of bearing [16-19].

Effect of Gravity at the Atomic Level

Research work has been performed that specifically compared the effect of gravity acting on individual atoms to the effect it exerts on an object like a baseball containing billions of atoms. It has been concluded that the force of gravity is nearly equal at both the atomic and the regular “macrosocopic” stages. In order to make this analogy, the researchers used a new method called atom interferometry to produce the most precise calculation of the force of gravity on individual atoms. They estimate their measurements to be accurate to 3 parts per billion. By directly comparing this result with the measurement of the acceleration of gravity made with the state-of-the-art gravimeter, they were able to demonstrate that the gravitational force acting on atoms subject to the rules of quantum mechanics is a little like which behaving on common objects regulated by the contemporary laws of physics via an unpredictability with just 7 parts for every billion [18-20].
Though the discovery is not surprising to scientists, it varies markedly from the findings of a set of research operated by scientists at the University of Missouri-Columbia and elsewhere. They have repeatedly tried to evaluate the force of gravity expected to act on subatomic particles named neutrons. While using a methodology named neutron interferometry, a few percent difference was found between the gravitational force acting on neutrons and those acting on larger objects. New results reinforce the likelihood that neutron measurements will be incorrect. “Because the fundamental principles of physics being used neutron interferometry, as well as atom interferometry, are of the same, the studies showed that there would be some element of neutron interferometry that is not fully understood. As significant as the finding itself is the fact that this experiment represents the coming era of atom interferometry, an innovative new tool for producing incredibly precise measurements. “It reveals that this type of atom interferometer can be used to make absolute measurements equal to the most sensitive measurement instruments in physics,” the scientists write in Nature. Previously, atom interferometers have demonstrated a high degree of precision, but the best precision reported was the variance of a few parts per thousand. The present study reflects a million improvement in absolute precision over previous atom interferometers [18-21].
Researchers have demonstrated that particle interferometers can go about as amazingly exact spinners and accelerometers. Particle interferometers misuse huge numbers of same fundamental standards from optical interferometers, instruments that have been utilized for over a century to make exact estimations of separations and other physical amounts. An optical interferometer isolates light into at least two pillars that take various ways and afterward reunites them. When united back, the waves include or take away with one another, shaping an example of light and dull groups called impedance borders. The position and dividing of the edges permit researchers to gauge the distinction in the separations of the light ways with extraordinary accuracy. An iota interferometer does a lot of something very similar. However, it utilizes iotas rather than photons. They are utilizing the basic wave/molecule duality that describes quantum mechanical marvels, the instrument parts iotas into two waves isolated in space. At the point when the two sections recombine, they meddle with one another, framing an example resembling visual obstruction borders. A state-of-theart gravimeter owned and managed by the National Oceanic and Atmospheric Administration was configured next to the atom interferometer to evaluate the force of gravity acting on atoms and larger objects.
The gravimeter is indeed an optical interferometer established such that only the light beam towards one arm is bounced from a free-falling glass cube. By calculating the rate over which the interference pattern travels. At the same time, the cube falls, the instrument could estimate the effects of gravity acting mostly on cube within about 2 parts per billion. The other interferometer utilizes lasers to cool a group of cesium iotas to inside a couple of millionths of a degree above supreme zero. At room temperature, molecules zoom about at supersonic velocities. When chilled off, they move at just a centimeter for every second - making it a lot simpler to gauge their position and speed. At that point, the moderate moving molecules are tenderly lobbed into a free-falling circular segment. Laser beats cause them to part separated and afterward recombine. Perusing the obstruction periphery designs that are delivered gives an exact estimation of the iotas’ speed in free fall. So, the wavelength of the particles was very narrower than that of the photons, the atom interferometer does tend to contribute far more accurate results than just its optical counterparts. One or two orders of magnitude can increase a further 3 to 4 orders of magnitude and precision. Therefore, because at the atomic and regular macrosocopic stages, the influence of gravity is nearly equivalent, so atomic level acceleration/deceleration will be attributed to gravity. In turn, this would also impact the current density. This could be the least effective on Earth, but it would affect other planets with greater gravity than on earth [18-21].

Variation in Current Density at Planets

As discussed in the previous section, gravity affects the atoms as it affects in general. Gravity causes acceleration at the atomic level. It may cause variation in current density, which in turn causes variation in current. Now in space science, the equipment is tried to be precise at the microscopic level for any variations to be suited on the Planet. It is going to be used. Table 1 presents the effect of gravity at the atomic level on different planets in comparison to Earth. Based on the observations from Table 1, it can be understood that there will be more acceleration as compared to Earth on Jupiter, Saturn, and Neptune. The deceleration may be observed as compared to Earth on Mercury, Venus, Moon, Mars, and Uranus.

Table 1: Effect of gravity at atomic level on planets vs. earth.


This paper presented the effect of gravity at the atomic level. The acceleration and decelerations may cause a variation in current and current density. In space research, it may affect critical research to be done at various planets. The equipment may behave adversely on the other Planet as compared to their behavior on Earth. An increase in current density may be observed at Jupiter, Saturn, and Neptune, whereas reduced current density may be observed on Mercury, Venus, Moon, Mars, and Uranus. The designing and testing of the equipment can be done in a manner to behave in the desired manner on the Planet it is going to be used.
