25 simple questions science still doesn't know the answer

Do you consider yourself a big fan of science? If so, then you probably know that science doesn't offer proof that works. On the contrary, it is concerned with proving that it does not work. This is the scientific method that we use every day.

For example, let's start with a simple question like "Can milk cause illness?" There is only one way to find out. We hypothesize and test it. Are you sick? Then let's check out another type of milk. Scientists are doing this all the time.

However, some questions still remain elusive. Either they cannot be verified in principle, or additional experiments are required. Here are 25 simple questions that science still has no answers.

Can we stop growing old?

Generally speaking ... what is aging? And why is this happening to us? The general consensus is that aging is associated with progressively more damage to molecules, although this is controversial. Regardless of the cause, the big question is - can we stop aging?

Is life and biology universal?

While physics and chemistry appear to be the same for the entire universe, scientists are still not sure if the rules of terrestrial biology apply to life forms on other planets. For example, will these life forms rely on the same molecules as ours? Or can they be based on completely different substances ... for example, silicon?

Is there a purpose and meaning for the existence of the universe?

Throughout most of history, science has wisely left this question to theology and philosophy.

Will humanity be able to ensure its existence on Earth in the next century?

A similar question has come up several times in history, especially before the industrial revolution. Many politicians and scientists believed that it was impossible to ensure the existence of such a large population. Of course, railways, electricity and industry have proven that this is not the case. However, this question continues to haunt us. Can we find another solution?

What is music and why do we listen to it?

Why should we enjoy listening to different combinations of sound vibrations at different frequencies? Why did people develop the ability to make music? And what purpose does it serve? One hypothesis is that, oddly enough, it promotes sexual reproduction, in a way, like the tail of a peacock. However, so far this is only a hypothesis, not a scientific theory.

Is it possible to create artificial fish?

And whether it can help solve the problem of hunger and overfishing. So far, the answer seems promising, but we'll have to wait and see.

Will we ever be able to predict the future of economic and social systems?

In other words, will economists be able to accurately predict financial crises. At the moment, this seems unlikely. However, the media are constantly trying to convince us.

What is more important, nature or nurture?

The age-old debate about what influences us more, the environment or our upbringing, seems to never end.

What is life?

We have several definitions, but how can you tell if something is alive? Admittedly, this is not an easy question? For example, at what point will computers have to be considered "alive"? Are viruses alive? Science still has no answer to these questions.

Will we ever be able to perform a successful brain transplant?

We can replace your limbs, but what about the brain? Another question that science is unlikely to answer in the near future.

Free will?

Do we have it? Were all our actions predetermined since the first atoms began to move? Quantum mechanics has come to several interesting but conflicting conclusions. We can never know how free we are ...

What is art?

Although Leo Tolstoy tried to provide an answer, scientists still doubt why we find "beauty" in patterns, shapes and colors. What purpose does art serve and, in general, why does it exist? Actually, what is beauty in general?

Did people discover mathematics or invent it?

Many of the things mentioned above are mathematics dependent. Chemistry, physics, music and so on. However, what comes first? Is the universe subject to some order? Why did everything fall into place just like that? Simply put, could an alien civilization understand our mathematical concepts?

What is gravity?

We know that objects are attracted to each other, but why? Some scientists have even proposed particles such as gravitons to explain this phenomenon.

Why are we here?

So we know that the Big Bang happened, and so on ... But why did all this happen?

What is Consciousness?

It's amazing how difficult it is to understand what is the difference between consciousness and unconsciousness. From a macroscopic point of view, everything is simple: one is awake and the other is not. But at the microscopic level, scientists are still trying unsuccessfully to understand what the difference is.

Why do we sleep

We used to think that we need to rest and recover. However, our brains actually work just as actively when we sleep, if not even more actively. Plus, we don't need 8 hours of minimal movement to recover from a day's work. In fact, we don't need sleep at all. Our muscles and cells are able to repair themselves when we are awake.

Are we alone in the universe?

Based on statistical modeling, it seems unlikely, not to say impossible, that we are the only ones in the universe. The question is how to find these other life forms, and if we found them ... would we recognize them as life? What if they turned out to be huge interstellar clouds?

Where is all the stuff in the universe?

If we take all the stars and galaxies in the night sky, they make up 5 percent of the mass-energy density of the universe. More than 95 percent is accounted for by dark matter and dark energy. That's right, we can't see it all. How do we know that it exists? We draw this conclusion based on its effect on visible matter.

Will we ever be able to accurately predict the weather?

The weather is known to be difficult to predict. It depends on local geography, humidity, air pressure, etc. A slight increase in humidity over one of the forest areas can completely change today's weather, which will completely change tomorrow's, etc.

What is morality?

What is right and what is wrong? Humans seem to have some kind of innate tendency to classify behavior into ethical categories. But why? What is murder? Is there a justified murder? How about theft? And why is eugenics, the theory of the survival of the fittest, and experiments in this area so disgusting? In fact, what is the essence of disgust? Ironically, although ethics is of great importance to science, it mostly exists in completely isolated.

Where did the language come from?

When people are born, they seem to already have an empty form for language. It's almost as if we expected to know something in advance. Verbs, noun prepositions. Depending on the specific language, they simply fill in pre-existing structures. In fact, this proto-language even has a name - mentalization, or thought code. However, here again a curious and unresolved question arises, why?

Who are we?

Remember the brain transplant? So if we load all the information into your head and make a computer program out of it, will it still be you? Or if we completely reproduce every atom of your body ... will it be you too? Or will it just be a super twin? Like many questions on our list, this question has not received an answer, because scientists have not yet been able to find out the truth empirically.

What is death?

There is clinical death when the heart stops beating. You can still return from it. There is biological death when tissue degeneration begins. But is there a clear line between them? At what point is it too late to return? This question is closely related to the question "what is life?"

What happens after we die?

Perhaps it will come as no surprise that this question is more in the realm of philosophy and religion than science. However, this does not mean that scientists still have questions.
