The statement is true.
As weird as it may sound, helium was indeed first discovered on the Sun, and after some time on Earth. The first evidence of helium was observed on August 18 1868, as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the Sun's chromosphere. This line has been detected by a French astronomer by the name of Jules Janssen during a total solar eclipse in Gantur, India.
The force that attracts any two pieces of matter in the universe is called the gravitational force.
<h3>What is gravitational force?</h3>
Corresponds to the mutual interaction between two bodies in space, being attractive and not repulsive, allowing the translational movement of the earth and the movement of planets in orbit around the sun.
Therefore, the gravitational force was proposed by Isaac Newton, in an episode in which the physicist observed an apple falling from a tree, identifying the way in which gravity causes objects to be attracted to the center of the earth.
