Contest alert: Share your general knowledge week 12
Hello my dear Steemians,
Today I wanted to write for this contest that is running by @sahar78 , here is the link if you are also interested:
When I read this question I was a bit surprised because so long we exist on Earth we know that there is no life on Mars. On other hand we had a lot of different stories, science-fiction and also movies when many years ago there was a life on Mars. Also we have seen many movies about future where Martians are more developed species and also who are more aggressive and would like to take over Earth.
Since the science so much developed we know that the condition of Mars was close to Earth one many thousands years ago. That time Mars had a magnetic core like Earth and has its atmosphere, that means there was air and species that could breath and live.
According the scientists about 4,1 billions year ago there was a live on Mars and but approximately so much years ago it extinct. Nobody will know for sure but it is what we know by now.
Enstein's theory of relativity is well known to everyone and that is an explanation of gravity and telling that gravity is curving the space, the bigger object the more force it has and it is reflects in the famous formula.
There are many movies with Sci-Fi background that were triggered by the discovery that was done in the field of Physic, even nowadays many new discoveries are based on that knowledge that was worked out by Enstein.
There are 195 countries on the world map, actually seeing this number it does not sound too many but there are many of countries are large and take majority of some continent. Some of them like Australia is one continent and one country.
Majority of countries belong to United Nations and that is something that we can help to each other.
