"Research into gravitational lensing, where light bends around massive objects, aligns with Einstein’s predictions from billions of years ago. However, newer findings suggest some deviations, indicating potential variations in gravitational behavior over large distances, sparking further investigation into the validity of Einstein’s theories.

Einstein's paradox, called the "Train paradox" is that an object can move very fast even if it's not moving at all. When we stand in a train that moves 200 km/h we can say that we don't move at all. But if somebody stands outside the train, that person can say, that we travel 200 km/h. In that case the space moves.  So the movement is energy. When we stand or sit in a moving train that means we don't use energy. The moving t

Cuillandre (CEA Paris-Saclay), G. Anselmi" (Unige, Einstein’s equations collide with the mysteries of the Universe) There is not very much research where the Theory of General Relativity is tested in extremely low gravity and energy levels. Those theories are well-tested around black holes. But there is not very much data about things like how gravity waves or some other waves or particles interact in conditions. Where energy travels out from them very fast.  The edge of the Universe is a mysterious place. There the energy and material face lower than exists our Universe. Or otherwise saying the energy in our Universe faces a cosmic void. Energy travels from space filled with quantum fields and wave movement to the cosmic void or into cosmic nothing. That space is not possible in the Universe. There are n

Srinivasa Ramanujan (1887-1920). (Quanta Magazine, Math Is Still Catching Up to the Mysterious Genius of Srinivasa Ramanujan) The number theory is thankful to Srinivasa Ramanujan (1887-1920). The thing that makes this person, who was born into a poor Indian family in colonial India was a self-educated person, who made a lot of things in mathematics. Those theories are still handy tools for many types of advanced calculations. There are many interesting details in the life of that young person, who passed away in 1920. Many people say that Srinivasa Ramanujan died too early. If that person could live a longer life, he might stand in the place of Albert Einstein.  There were many interesting things in Ramanujan's early life. The thing is that Ramanujan failed twice in college. Because of his passion for mathematics. And that's why he flees from home. Maybe he was afraid that his parents were angry. Finally, he went to Trinity College Cambridge where he started to work with Hardy
