Gravity, what is it? What is the force in the material Universe called Gravity?

So what causes the forces in all the material universe called gravity?

Srila Prabhupada says he does not believe in gravity, what does he mean? Einstein also did not believe in the idea of ''Newton's laws of gravity'' in his time.

Therefore, not only Prabhupada, but Einstein also did not agree with Newton's law of gravity. The meaning of the word ''gravity'' is a word trying to explain a universal force, this was not explained correctly by Newton's that Prabhupada also rejected.

Einstein's explanation of ''the universal force through all the material universe (gravity) is simple, it is objects bending spacetime. So curved space is gravity according to Einstein.

This concept was still new in the 1960s and 70s and Prabhupada never commented on this. His explanation was even more simple than Einstein space curvature and mass

**Srila Prabhupada** - ''Ultimately Krishna's laws hold the universes together, Lord Ramacandra was able to make a bridge by causing the big stones to float n the water, so counteracting the law of gravitation is the law of the Supreme''.

**Srila Prabhupada** - ''Gravitation is caused by the Supreme Lord, so He is also able to remove that law or do anything and everything at His will''.

Other than those comments, Prabhupada never really understood gravity also included the the mass of an object. This is why a stick of wood will float and a piece of steel the same size will sink in water. This ''mass of an object'' Prabhupada never understood as found in the following letter.

**He tried to explain in a letter to Rupanuga - Tokyo 3 May, 1972**

**Srila Prabhupada** - ''Another revelation about so called gravity is that the needle, when put into the water, it goes down quickly to the bottom. But a big, big log, weighing one ton, does not go down. Who has made this law? If the law of gravity is there, why does it not apply to the big log? If you know something like swimming, then the law of gravitation will not work'' Tokyo 3 May, 1972

Today in 2019 because young people are well educated, even a 6th grader will point out Prabhupada's misunderstanding above in using the word gravity.

But Prabhupada's main point is who knows better than Lord Krishna how to do everything, so Krishna can change anything, therefore we worship Him as the greatest Scientist.

Not only Prabhupada but Einstein also did not agree with Newton's law of gravity.

It became apparent during the latter part of the nineteenth century that there is a conflict between Newtonian mechanics and classical electrodynamics. Einstein, and a few others before him addressed this conflict in a variety of ways.

Einstein’s way was to find a new mechanics, which is consistent with electrodynamics, but reduces, in approximation, to Newtonian mechanics for objects moving at speeds that are small compared to the speed of light in vacuum.

Experiments with subatomic particles (particularly muons in secondary cosmic rays created high in the atmosphere) moving at nearly the speed of light have shown that Einstein’s theory of special relativity explains the behavior of these particles, but Newton’s mechanics does not.

More recently, with satellites used by GPS, it has been necessary to use Einstein’s special and general relativity to keep the calculated positions of objects on Earth accurate.

Both the special theory and the general theory of relativity have passed every experimental and observational test we have been able to devise, but Newton’s theory does not agree with experience at the level of accuracy we can now achieve.

What role does the atmosphere or ''air'' play on gravity?

Srila Prabhupada explains that planets floating in outer space is due to the manipulation of the air.

This is true for birds and 747s, even water cannot exist as a liquid without the presence of air, water in a vacuum without air immediately turns to ice.

However, the so called presence of ''air'' does not make sense outside earth's atmosphere where there is no air. This is a fact, there is no manipulation of the air that we know on our globe, in outer space.

Outer space is almost a vacuum as seen from our dimension of space-time

Even on earth the higher you go the thinner the air; so this following statement must be maturely decoded and understood because the word ''air'' must mean something else as the air we breath does NOT exist in outer space, this is no theory it is a proven fact.

This is Srila Prabhupada's comment on why planets float but needs a proper interpretation that simply does not exist in these early pioneering years where some devotees foolishly clam this planet is flat and satellites are a hoax.-

**Srila Prabhupada** - ''All these planets are moving only by the air. So the heavy land, heavy cloud is carried by the air. It is a question of adjustment of air, not the law of gravity. Now the whole universal planetary system are floating and rotating round the polestar. Is that law of gravity, rotating?

It is the arrangement of the air. By the air it is up. Just like there is dust storm, so many are floating in the air. There is no question of law of gravity; it is the air. And the..., who is controlling the air?''

Srila Prabhupada says he does not believe in gravity, what does he mean? Einstein also did not believe in the idea of gravity in his time.

Einstein's general theory of relativity tells us that gravity does not exist in the way Newton's science believed which is -

''Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull.

The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.

We tend to think of gravity as a force that affects objects, but Einstein showed it was something else.

You jump up, and gravity brings you back down to Earth. You reach the brow of a hill and gravity accelerates you down the other side. People used to think gravity behaves in the way Newton thought of it, as a force that affects and changes the motion of something else.

That was how it seemed until Einstein came along. His general theory of relativity tells us that gravity is not quite that simple and does not exist in the way Newton's science believed.

General relativity provides a framework under which the laws of physics look the same for everyone at every moment, regardless of how they are moving. Einstein achieved this by making gravity a property of the universe, rather than of individual bodies.

General relativity describes gravity as geometry. The fabric of the universe – the four dimensions of space and time – is full of lumps and bumps created by the presence of mass and energy.

This warping is unavoidable; whenever anything – be it you, me, a piece of space dust or a photon of light – tries to travel through the universe in a straight line, it actually follows a trajectory that is curved by any mass and energy in the vicinity.

The result of this curvature is what we think of as gravity. To look at it a slightly different way, gravity is not what one body does directly to another, but what a body’s mass does to the surrounding universe.

All the other forces in nature have opposites. In the case of the electromagnetic force, for example, it can attract or repel, depending on the charges of the bodies involved. So what makes gravity different?

The answer seems to lie with quantum field theory. The particles that transmit the strong, weak and electromagnetic forces have various types of charge, such as electric or colour charge.

“Those charges can be either positive or negative, leading to different possibilities for the sign of the force,” says Frank Wilczek of the Massachusetts Institute of Technology.

This is not the case with gravitons, the hypothetical particles that quantum field theory says should transmit gravity. “Gravitons respond to energy density, which is always positive,” says Wilczek.

Or are we assuming too much here? “We don’t know that gravity is strictly an attractive force,” cautions Paul Wesson of the University of Waterloo in Ontario, Canada.

He points to the “dark energy” that seems to be accelerating the expansion of the universe, and suggests it may indicate that gravity can work both ways.

Some physicists speculate that dark energy could be a repulsive gravitational force that only acts over large scales.

“There is precedent for such behaviour in a fundamental force,”

Wesson says. “The strong nuclear force is attractive at some distances and repulsive at others.”

Either way, the apparent difference between gravity and the other fundamental forces poses a problem for physicists wanting to create a “theory of everything” that provides a single explanation for them all.

Einstein was among the first scientists to try to marry gravity with other theories of physics, yet we may be no closer now than he was when he began his search.

The most popular quantum gravity theories today seem to have fundamental problems that no one knows how to solve.

The Conclusion -

Srila Prabhupada - ''Ultimately Krishna's laws hold the universes together, Lord Ramacandra was able to make a bridge by causing the big stones to float n the water, so counteracting the law of gravitation is the law of the Supreme, gravitation is caused by the Supreme Lord, so He is also able to remove that law or do anything and everything at His will''. (Tokyo 3 May, 1972)

"When bulls are yoked together and tied to a central post to thresh rice, they tread around that pivot without deviating from their proper positions—one bull being closest to the post, another in the middle, and a third on the outside.

Similarly, all the planets and all the hundreds and thousands of stars revolve around the polestar, the planet of Mahārāja Dhruva, in their respective orbits, some higher and some lower.

Fastened by the Supreme Personality of Godhead to the machine of material nature according to the results of their fruitive acts, they are driven around the polestar by the wind and will continue to be so until the end of creation.

These planets float in the air within the vast sky, just as clouds with hundreds of tons of water float in the air or as the great śyena eagles, due to the results of past activities, fly high in the sky and have no chance of falling to the ground. (Srimad Bhagavatam Canto 5 Chapter 23 Text 3)

PURPORT

According to the description of this verse, the hundreds and thousands of stars and the great planets such as the sun, the moon, Venus, Mercury, Mars and Jupiter are not clustered together because of the law of gravity or any similar idea of the modern scientists.

These planets and stars are all servants of the Supreme Personality of Godhead, Govinda or Kṛṣṇa, and according to His order they sit in their chariots and travel in their respective orbits.

The orbits in which they move are compared to machines given by material nature to the operating deities of the stars and planets, who carry out the orders of the Supreme Personality of Godhead by revolving around Dhruvaloka, which is occupied by the great devotee Mahārāja Dhruva.

This is confirmed in the Brahma-saṁhitā (5.52) as follows:

yac-cakṣur eṣa savitā sakala-grahāṇāṁ
rājā samasta-sura-mūrtir aśeṣa-tejāḥ
yasyājñayā bhramati sambhṛta-kāla-cakro
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi

“I worship Govinda, the primeval Lord, the Supreme Personality of Godhead, under whose control even the sun, which is considered to be the eye of the Lord, rotates within the fixed orbit of eternal time.

The sun is the king of all planetary systems and has unlimited potency in heat and light.”

This verse from Brahma-saṁhitā confirms that even the largest and most powerful planet, the sun, rotates within a fixed orbit, or kāla-cakra, in obedience to the order of the Supreme Personality of Godhead.

This has nothing to do with gravity or any other imaginary laws created by the material scientists.

Material scientists want to avoid the ruling government of the Supreme Personality of Godhead, and therefore they imagine different conditions under which they suppose the planets move.

The only condition, however, is the order of the Supreme Personality of Godhead.

All the various predominating deities of the planets are persons, and the Supreme Personality of Godhead is also a person.

The Supreme Personality orders the subordinate persons, the demigods of various names, to carry out His supreme will. This fact is also confirmed in Bhagavad-gītā (9.10), wherein Kṛṣṇa says:

mayādhyakṣeṇa prakṛtiḥ
sūyate sa-carācaram
hetunānena kaunteya
jagad viparivartate

“This material nature is working under My direction, O son of Kuntī, and it is producing all moving and unmoving beings.

By its rule this manifestation is created and annihilated again and again.”

The orbits of the planets resemble the bodies in which all living entities are seated because they are both machines controlled by the Supreme Personality of Godhead.

 ? As Kṛṣṇa says in Bhagavad-gītā (18.61):

īśvaraḥ sarva-bhūtānāṁ
hṛd-deśe ’rjuna tiṣṭhati
bhrāmayan sarva-bhūtāni
yantrārūḍhāni māyayā

“The Supreme Lord is situated in everyone’s heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy.”

The machine given by material nature—whether the machine of the body or the machine of the orbit, or kāla-cakra—works according to the orders given by the Supreme Personality of Godhead.

The Supreme Personality of Godhead and material nature work together to maintain this great universe, and not only this universe but also the millions of other universes beyond this one.

The question of how the planets and stars are floating is also answered in this verse. It is not because of the laws of gravity. Rather, the planets and stars are enabled to float by manipulations of the air.

It is due to such manipulations that big, heavy clouds float and big eagles fly in the sky.

Modern airplanes like the 747 jet aircraft work in a similar way: by controlling the air, they float high in the sky, resisting the tendency to fall to earth.

Such adjustments of the air are all made possible by the cooperation of the principles of puruṣa (male) and prakṛti (female).

By the cooperation of material nature, which is considered to be prakṛti, and the Supreme Personality of Godhead, who is considered the puruṣa, all the affairs of the universe are going on nicely in their proper order. prakṛti, material nature, is also described in the Brahma-saṁhitā (5.44) as follows:

sṛṣṭi-sthiti-pralaya-sādhana-śaktir ekā
chāyeva yasya bhuvanāni bibharti durgā
icchānurūpam api yasya ca ceṣṭate sā
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi

“The external potency, māyā, who is of the nature of the shadow of the cit [spiritual] potency, is worshiped by all people as Durgā, the creating, preserving and destroying agency of this mundane world.

I adore the primeval Lord Govinda, in accordance with whose will Durgā conducts herself.”

Material nature, the external energy of the Supreme Lord, is also known as Durgā, or the female energy that protects the great fort of this universe.

The word Durgā also means fort. This universe is just like a great fort in which all the conditioned souls are kept, and they cannot leave it unless they are liberated by the mercy of the Supreme Personality of Godhead. The Lord Himself declares in Bhagavad-gītā (4.9):

janma karma ca me divyam
evaṁ yo vetti tattvataḥ
tyaktvā dehaṁ punar janma
naiti mām eti so ’rjuna

“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.”

Thus simply by Kṛṣṇa consciousness, by the mercy of the Supreme Personality of Godhead, one can be liberated, or, in other words, one can be released from the great fort of this universe and go outside it to the spiritual world.

It is also significant that the predominating deities of even the greatest planets have been offered their exalted posts because of the very valuable pious activities they performed in previous births. This is indicated herein by the words karma-nirmita-gatayaḥ.

For example, as we have previously discussed, the moon is called jīva, which means that he is a living entity like us, but because of his pious activities he has been appointed to his post as the moon-god.

Similarly, all the demigods are living entities who have been appointed to their various posts as the masters of the moon, the earth, Venus and so on because of their great service and pious acts.

Only the predominating deity of the sun, Sūrya Nārāyaṇa, is an incarnation of the Supreme Personality of Godhead.

Mahārāja Dhruva, the predominating deity of Dhruvaloka, is also a living entity. Thus there are two kinds of entities—the supreme entity, the Supreme Personality of Godhead, and the ordinary living entity, the jīva (nityo nityānāṁ cetanaś cetanānām).

All the demigods are engaged in the service of the Lord, and only by such an arrangement are the affairs of the universe going on.

Regarding the great eagles mentioned in this verse, it is understood that there are eagles so big that they can prey on big elephants.

They fly so high that they can travel from one planet to another. They start flying in one planet and land in another, and while in flight they lay eggs that hatch into other birds while falling through the air.

In Sanskrit such eagles are called śyena. Under the present circumstances, of course, we cannot see such huge birds, but at least we know of eagles that can capture monkeys and then throw them down to kill and eat them.

Similarly, it is understood that there are gigantic birds that can carry off elephants, kill them and eat them.

The two examples of the eagle and the cloud are sufficient to prove that flying and floating can be made possible through adjustments of the air.

The planets, in a similar way, are floating because material nature adjusts the air according to the orders of the Supreme Lord.

It could be said that these adjustments constitute the law of gravity, but in any case, one must accept that these laws are made by the Supreme Personality of Godhead.

The so-called scientists have no control over them.

The scientists can falsely, improperly declare that there is no God, but this is not a fact.
