1.Are we alone?
There is a lot of stars in the sky. Some of them are similar to our sun. In numbers, it is possible that we are not alone. But are we alone nobody can answer. We can’t say that we are alone and we can’t say that we are not. We even can’t say that universe is infinity.

2.What happens after death?
Our conscious can’t imagine what we had never experienced. We can’t image the situation in which we do not exist. We can imagine that our body dies and conscious stays alive. But we still don’t know anything about this simple process. Science can’t prove that afterlife exists or not.

3.Where is our conscious?
We all think that human’s conscious is in his brains. We can explore our brains: we can scam them, we can detect thoughts, we can trace neuron chains but our conscious stays in a very big enigma. Some people think that conscious is given by the bigger force(God). Science believes that they will find the answer by exploring more simple animals by understanding how do they recognize them self.

4. Can we cure cancer?
Searching on the internet you can find a lot of information how science made a progression of finding the cure. It looks like soon we will find a cure, but in reality, we still don’t how we get cancer. A disease caused by an uncontrolled division of abnormal cells in a part of the body. But why it is happening? DNR violations the main cause of cancer and the main research target. Now we have a better way to cure cancer than 50 years ago but still, this is a very slow process. Probably we need to wait another 50 years for the better cure.
5.How many different species are living on the Planet earth?
To qualify all planet’s species, require a lot of hard work and time. This job was started 200 years ago, but we are still far away from counting them all. Probably, we know about only 15% of all species living on the planet. But even we will try our best we are not able to count them all. The biggest problem is with smallest animals. But even with big ones, we have a lot of problems. Sometimes different species found to be from the same family. Let’s take dog’s, we have a big variety, but they are all from the same species. We breed dog’s and we know that is that same species, but when we see a different animal we think that is from a different species. It may be, that we will never be able to count them all.
