The vast universe always seems so mysterious. Since ancient times, people have been exploring the mysteries of the universe, but there are still many mysteries that have not been solved. Let's take a look at the five unsolved mysteries of the universe.

1. Phantom in Eagle Nebula

One of the strangest pictures in space is the Eagle Nebula. The photo itself shows the birth of a star from a gas cloud. This space contains a lot of gas and dust, showing the scene of star formation. After the researchers processed these pictures, they found that there seems to be a huge human figure inside. What's interesting is that we can see similar phenomena in many cosmic images.

2. Where do galaxies come from?

What we know now is that galaxies have not been wrongly divided into the universe, but have gathered together, enjoying the reputation of "super cluster". Scientists have two theoretical bases for galaxy formation. First, the gas released by the big bang gathered together to form galaxies; Second, the gas released by the big bang formed stars and planets. These gases were affected by gravity to form galaxies. However, these two theories have not been generally accepted.

3. Are there any other earth like planets suitable for life in space?

Since 2000, astronomers have discovered hundreds of exoplanets that orbit distant stars. These are some earth-like planets such as Gliese 581d. Scientists have observed that there is liquid water on their surface. Is it possible that there is life? With the continuous progress of science and technology, I hope we can know the answer as soon as possible. Even so, it is still one of the biggest mysteries in the universe.

4. Is there another universe?

This issue is quite controversial. It has been proved that the universe is multidimensional. As far as the universe is concerned. Most people now believe that the membrane universe theory means that the universe we live in is like a layer of cosmic membrane, which exists in another higher dimensional universe. Another view is that there are infinite universes in the world, and each universe has its own operating law; Others believe that there is no evidence that the universe exists. This puzzle may not be solved until we go to another universe, but when the universe expands, mankind will never find the answer.

5. Dark Matter

Perhaps Einstein's "e=mc squared" formula is the most famous one. However, when applied to space problems, some abnormal phenomena will occur. For example, when we use it to determine the mass of the universe, we can only get 4% of the matter in the universe. Where will other substances go? Scientists believe they exist in the form of dark matter. What is dark matter? If you can't see, dark matter exists. This thing is very strange. Not only does it not emit light, but also light does not come in, so people can't see it. The most amazing thing is that although it cannot be touched, it has weight and gravity. Scientists have no conclusive evidence to prove the existence of dark matter, which is called the "mystery of the century". Dark matter exists wherever you can't see.
