Shadows change over time as the position of the light source changes, such as the sun moving across the sky or objects blocking the light. Additionally, shadows can also change in length and direction as objects move relative to the light source. Atmospheric conditions can also affect the appearance of shadows over time.
The circle of light you see when you look through a microscope is called the field of view. It represents the area of the specimen that you can see through the microscope's lenses at one time.
The compound light microscope was invented around the late 16th century, with credit often given to the Dutch spectacle maker Zacharias Janssen as one of the early inventors. The exact year of its invention is not definitively known due to the lack of detailed records from that time period.
The sun's energy has increased steadily over time due to nuclear fusion reactions in its core. As the sun burns hydrogen to helium, it releases energy in the form of light and heat. It is estimated that the sun will continue to increase in energy output over the next billion years before entering the red giant phase.
All the stars and the Sun are moving through space in different directions and at different speeds. Over long times (to a person) they change their positions in the sky and the constellations change.
The light microscope was not invented by a single individual, but rather developed over time by multiple scientists. Hans Lippershey is credited with the invention of the compound microscope in the late 16th century, which laid the foundation for the modern light microscope. Later advancements by scientists like Robert Hooke and Antonie van Leeuwenhoek further improved the design.

It should have been a light microscope considering the period of time he lived in.
It was developed, and then you might say improved or modified over time. Zaccharias Janssen and Hans Janssen experimented with lenses that would help make the light microscope, as did Galileo. Anton van Leeuwenhoek also experimented with microscopes and so did Robert Hooke.

this can never change, light travels at a constant speed, a light year is the distance light travels in one year.

That is when the DNA is condensed, at which time it is called chromosome.
Light microscopes are advantageous for observing living specimens in real time due to their lower energy beam, which minimizes damage to samples. They are also more affordable and easier to use compared to electron microscopes, making them accessible to a wider range of researchers.
The discovery of various cells, including plant cells by Robert Hooke and animal cells by Anton van Leeuwenhoek, were achieved using a light microscope. The light microscope enabled scientists to observe and study cells for the first time in the 17th century.
