There has been multiple misinterpretations and wrong translations of Vedic hymns into english and other languages, where they though Earth was flat. But Roundness of Earth, Centrifugal and Centripetal we can find about Forces between Sun and Earth, Moon Light, Rotation and Revolution of Earth, Eclipses in Vedas like Rig Veda and Yajur Veda.
People who do not have proper understanding of Sanskrit have tried to interpret according to their own limited wisdom.
Rotation and Revolution of Earth
ahastÁ yád apádI várdhata kSÁH shácIbhir vedyÁnAm
shúSNam pári pradakSiNíd vishvÁyave ní shishnathaH [Rig Veda 10.22.14]
Translation : This earth is devoid of hands and legs, yet it moves ahead. All the objects over the earth also move with it. It moves around the sun.
Centripetal force between Sun and other planets
savitÁ yantraíH pRthivÍm aramNAd askambhané savitÁ dyÁm adRMhat
áshvam ivAdhukSad dhúnim antárikSam atÚrte baddháM savitÁ samudrám [Rig Veda 10.149.1]
Translation : Sun has tied Earth and other planets through attraction and moves them around itself as if a trainer moves newly trained horses around itself holding their reins.
“O Indra! by putting forth your mighty rays, which possess the qualities of gravitation and attraction-illumination and motion – keep up the entire universe in order through the Power of your attraction.” – Rig Veda 8.12.28
“O God, You have created this Sun. You possess infinite power. You are upholding the sun and other spheres and render them steadfast by your power of attraction.” – Rig Veda 1.6.5, Rig Veda 8.12.30
“The sun moves in its own orbit in space taking along with itself the mortal bodies like earth through force of attraction.” – Yajur Veda 33.43
“The sun moves in its own orbit but holding earth and other heavenly bodies in a manner that they do not collide with each other through force of attraction.” – Rig Veda 1.35.9
“Sun moves in its orbit which itself is moving. Earth and other bodies move around sun due to force of attraction, because sun is heavier than them.” – Rig Veda 1.164.13
“The sun has held the earth and other planets” – Atharva Veda 4.11.1
Source of Moon Light in Vedas
átrÁha gór amanvata nÁma tváSTur apIcyàm
itthÁ candrámaso gRhé [Rig Veda 1.84.15]
Translation : The moving Moon always receives a ray of light from Sun.
sómo vadhUyúr abhavad ashvínAstAm ubhÁ varÁ
sUryÁM yát pátye sháMsantIm mánasA savitÁdadAt [Rig Veda 10.85.9]
Translation : Moon decided to marry. Day and Night attended its wedding. Sun gifted his daughter “Sun ray” to Moon.
Solar Eclipse in Rig Veda
Unlike the (un)popular stories of a demon swallowing Sun, Solar Eclipse has been properly described as Moon blocking Sun light from reaching earth.
yát tvA sUrya svàrbhAnus támasÁvidhyad AsuráH
ákSetravid yáthA mugdhó bhúvanAny adIdhayuH [Rig Veda 5.40.5]
Translation : O Sun! When you are blocked by the one whom you gifted your own light (moon), then earth gets scared by sudden darkness.
Here Tamas and Asura are darkness and blockage.
Telegraphy in Vedas
yuvám pedáve puruvÁram ashvinA spRdhÁM shvetáM tarutÁraM duvasyathaH
sháryair abhídyum pRtanAsu duSTáraM carkRtyam índram iva carSaNIsáham [Rig Veda 1.119.10]
Translation : With the help of bipolar forces (Aswins), you should employ telegraphic apparatus made of good conductor of electricity.
It is necessary for efficient military operations but should be used with caution.
