Why is space dark even though there are an infinite number of stars?

According to many astronomers, it is estimated that there are several sextillion stars in the universe that can be observed with current technology.

However, despite the presence of many bright celestial objects,… space The astronomer still suffers from a noticeable absence of illumination.

Many wonder why this happened, as it would be natural to imagine that such elements would illuminate the dark void.

However, this issue is not that simple and has already sparked a lot of discussion among the main authorities in the region. Even today there are some discussions about this topic.

Why can’t stars light up space?

This issue in particular gave rise to a theory called “Olbers’ Paradox”, formulated by the German astronomer Heinrich Wilhelm Matthias Olbers in the nineteenth century.

In short, he claims that Outer Space It remains dark because the universe is not infinite, at least as studied so far.

While observing the sky, the researcher asked the same question with which we began this text.

Man soon began to study the finitude of the universe and concluded that the lack of light would be a sign that space would have an end, contrary to what most scientists believed.

“It turns out that if the universe were infinitely large and old, we would expect the night sky to be bright, because of the light from all those stars. In every direction you look in space, you will be looking at a star.”

But we know from experience that space is dark! This paradox is known as Olbers’ paradox, as described by the US National Aeronautics and Space Administration (NASA) in an official publication.

However, such a discrepancy would be just one explanation. Other academics have already tried to provide solutions to this problem, and their conclusions are very interesting.

For example, some of them believe that a cosmic phenomenon called redshift would shift lights red.

Thus, as some stars get further away, their brightness remains outside the spectrum of light that we humans can see.

Finally, even if being It’s not infinite, it’s still gigantic. For this reason, scientists claim that there was no time for the brightness of all the stars to reach our planet.
