We see the exact time of sunrise and sunset every morning. Based on that, we decide the time of worship, but the sun is not really there when we see the sunrise or sunset. The views of the sun we see are from the past. The sun’s current has not yet reached us.
Are sunrise and sunset real or just our illusion?
Today the time of sunrise was 6-39 am. Many devotees performed Surya Pooja by seeing the Sun at a certain time, but the Sun we saw during Surya Pooja was the past form of 8 minutes, 20 seconds ago. At that time, the Sun had reached a distance of 2,08,32,500 km from there. The rays of that current have not reached us. Even now, if you look at the sun, the country you will see will be 8 minutes, 20 seconds ago. The sun must have reached 2,08,32,500 kilometers away from that place. The reason for this is the law of every atom in the universe to be constantly moving and changing. When science was in its infancy, people believed that the sun was stationary and the earth revolved around the sun. The moon revolved around the earth. Today, science has discovered that the sun is also not stationary. It revolves around the center and takes 2.5 million years to complete one orbit.
If the earth is seen from above the sun, it is a view of the instant present right?
If we look at the earth from the sun, even though the earth is visible from the sun at that moment. Actually it is the past of the earth. We see the sun 8 minutes, 20 seconds late. If you look at the earth from above the sun, it will look like 16 minutes, 40 seconds ago, because the light of the sun is produced by the sun itself. The earth does not produce light, it reflects the sun’s light. So it takes 8 minutes, 20 seconds for the sun’s light to reach the earth and 8 minutes, 20 seconds for it to reach the earth and return to the sun. Meanwhile, the earth has reached a distance of 29,722 kilometers in its orbit.
Sun’s constant moving speed is billions of kilometers.
The speed of Sun’s rotation around the center of Dudhganga is about 8.28,000 km per hour. Speed roughly says that there is likely to be a slight variation in the measurement of the Sun’s speed depending on the Earth, Moon and other planets. If the speed of sun is 8,28,000 km per hour, then the speed of every minute is 13,800 km and the speed of every second is 230 km. Sun is on average 14.9 crore kilometers from earth and the speed of light is 1.8 crore kilometers per minute. That is three lakh kilometers every second. Despite the speed of Mercury, the light from Sun takes 8 minutes, 20 seconds to reach the Earth. So we cannot see the sun’s current. When does light appear?: We see when light reaches our eyes. When the light of the sun that was emitted from the sun 8 minutes, 20 seconds before reaches our eyes, we see the place where the sun was going at that time. Even though the sun was not in that place at that time, it continued to move towards the west and reached a distance of 2,08,32,500 km. It will appear there only after 8 minutes, 20 seconds.
If every body of the universe, every particle is in motion!
Now think: not only our Sun, Earth, other planets and the moons of every planet, but also all the stars, the solar systems of all the stars and the Milky Way are constantly rotating in their own orbits. On the other hand, all star constellations are hundreds, thousands, millions of light years away from Earth.
Light travels through space at a speed of 108 million kilometers in an hour.
The number of kilometers it travels in one year is called the distance of one light year. Suppose if a star is 100 light years away from Earth, the view we see at this moment is 100 years ago. In a hundred years, that star must have reached billions of kilometers away. We see it billions of kilometers ago. So is that view true or illusion? Is it called current?
Even the sight of the moon appears to us after a second and a half,
The Moon orbiting the Earth is on an average 3,84,400 km away from the Earth. The speed of light is three hundred thousand kilometers per second. The Sun’s light also reaches the Moon 8 minutes, 24 seconds late on average. It takes 1.28 seconds to hit there and come back to earth. That is, the visible form of the moon is one and a half seconds ago. The moon revolves around the earth at a speed of 3,680 kilometers per hour. So when we see it, it has reached 1.31 km away from its place.
One more thing needs to be considered here.
We need to consider the latest discoveries of science. We have seen that if the sun is moving at a speed of 8,28,000 kilometers per hour, then the earth has to move at the same speed to revolve around it and the moon also has to move at the same speed with the earth. Keeping this fact in mind, let’s think of an example to visualize the Garba of the Earth, put Mataji’s Garba in the rickshaw and keep driving the rickshaw and then you keep going around Mataji’s Garba, what shape will your Garba be? If you do it yourself, you will understand how the Earth and other planets revolve around the Sun and how the moons of the planets like Earth, Mars, Saturn etc. revolve around their respective planets. All the bodies move around in mobile orbits. All move forward in a circular motion in the shape of a stretched spring.
