We all know that in the black hole the gravitational force is very high so that even light can't reflect the black hole. for the last ten years,, we collected some information about the black hole.

According to Albert Einstein, the black hole is going to small by itself.

But modern scientist believe that it the way of another universe,

Our mind is to work as a central computer and manage every body's activities.

We can find by our mind's scan that 100 billion neuron cells they complexly send and receive an electrical signal. And mind and consciousness aren't the same, Because electrical signal can't explain how the brain works as a consciousness, There are near death experiment, and out of body experiment proves that when brain stopped to work but consciousness still active.

And What is Consciousness? Where its come from? We don't know.

There are too many videos, and photos are available for proves the existence of the ghost.

But Scientist didn't get any strong evidence for proves that existence of the ghosts.

Scientist and ghost hunter trying to collect evidence using electromagnetic field detector and thermal imaging technology. But their evidence isn't able to the existence of ghosts.

According to the scientist, There is a brain disease, ocular vibration and in brain cause of electric signal. Its theory neither can be proved nor be disproved. Ghosts are still becoming mysterious for us.









7. How does the placebo effect Work?





The fake treatment where the patient believes that he/she will be fine soon.

Many patients are recovering from this technic.

Humans are thinking about this question many thousand years.

Ancient civilisations believed that by deeds, the soul goes to heaven or hell.

Some religion believed that for re-birth. But now In the nearest time of death, science can know when the person will die. But scientists don't know what happens after death. It's also mysterious.

There are many blood types like A, B, O, AB

And its divide to two positive and negative.we know the antigens in blood didn't allow to work for other blood types. So that we need the same blood types. In modern science know too many information about blood, How its made? , what are works? , how it works?

But we don't know why there are blood types of human.





10. How many species are there on earth?





We are trying to live in Mars, But you would be surprised to know that we do not know about the Earth as much about this universe. Because In the 75% of the earth is only water.

And we can't go to many places on this. So we don't know there any new species are there.

When a scientist goes to any new places, they apparently find any new species.

So There is no answer how many species are on earth.
