Gravity is an ubiquitous physical magnitude on the surface of the Earth. There is no material or device capable of eliminating it. The only way to not feel gravity is in free fall. Some airplanes make a maneuver that consists in describing a parabola like the one that would make an arrow shot by an […]
Gravity, a matter of weight
We will travel to Bremen, in Germany, where there is one of the highest drop towers in the world (ZARM), capable of generating microgravity conditions of almost 10 seconds, and which is used by the European Space Agency (ESA) to test space technology. We will measure the differences of gravity between the level of the […]
Searching for life in the Univers
We knew that the Earth is not flat, and that is not in the center of the universe, now it has been discovered that even in the Milky Way there could be 10,000 milion planets similar to ours. We explain how planets are detected outside our solar system and what conditions would have to sustain […]
