Science is expected to give answers to the important and the unimportant phenomena that take place around us, and the truth is that most of the time, it does not disappoint us. But there still remain mysteries that even the greatest scientists do not have an explanation for.

Here are some of the questions science has no answer to:

1. What is consciousness?

Most of us have an idea about what consciousness is, but scientists have not yet defined it or even understood it fully. There are many theories about consciousness, and some of them even refer to quantum mechanics, but none can give a clear explanation.

Scientists hope that in the future, by improving the synthesis of artificial organisms and robots, they will get closer to understanding the phenomenon of consciousness.

2. What happened before the Big Bang?

According to some scientists, before the Big Bang, there was no space or time, so the question is meaningless. Was the universe created out of nothing? Out of chaos? Then where did the chaos come from? Some questions just seem to be impossible to think about because of the restrictions of human perception.

3. What to do about the growing world population?

We constantly hear discussions about renewable energy, recycling, sustainable crops… But the growing population on the planet is an issue that confuses most of us. How can the planet sustain such a population? Especially if, according to recent research, life expectancy might increase up to 120 years in the future

4. How many planets are there in our solar system?

Ever since Pluto was banished from our solar system and is no longer considered a normal planet but only a “dwarf planet”, many have begun to have doubts about how many planets there are and where exactly they are located.

At present, the official science acknowledges “the Sun and the eight planets”, but God knows whether all this will change and whether new planets and worlds will be discovered.

5. Why is ice slippery?

Query equivalent of “why is water wet”, which, despite its seeming simplicity, has not yet got a clear scientific explanation.

6. Is it possible to record one’s thoughts (just like to record a TV program)?

In other words, will we be able to re-experience the situations we experienced in the past? For example, to fall in love with someone once more? Will it become possible to record our dreams and watch them when we are awake? Sounds shocking and unprobable. And it is one of the questions science has no answer to right now.

7. Will humanity ever reach the stars?

In the next 100 years, as scientists say, we will be likely to approach the limits of our solar system and the technological advances will make it possible to send astronauts and robots to the outskirts of it. However, the question is: when will each of us have the possibility to travel to the stars and visit other planets (for example, on vacation)? This question remains open, and more likely than not, space tourism will be only available to extremely wealthy individuals.

8. What is deja vu?

Deja vu means “already seen” and describes the eerie feeling we have when we think we re-experience a situation or an event. Various studies of recent years provide some common sense explanations at times, but the real cause and nature of this phenomenon remain a mystery. It is certainly one of those questions science has no answer to and probably will struggle to find.

9. Do ghosts exist?

Science never gave a clear explanation of what exactly ghosts are or whether they exist or not. Moreover, any attempt to study this phenomenon is not taken seriously, and any idea or theory on this is considered pseudoscientific.

These are just some of the questions science has no answer to. Hopefully, future advances in technology and scientific methods will give us the solutions for these and other puzzling mysteries that occupy the human mind.
