Newton's Laws are known as the "slow speed" approximation of physical laws (they are also the "large scale" approximation- we talk about this when we are discussing how they contradict Quantum Mechanics). What is important to remember, it isn't that Newton's Laws are "wrong" and Einstein's Laws are "right." Both sets of laws are mathematical models of what actually happens, and Einstein's Laws cover a wider variety of cases than Newton's Laws, but they are still a model, which does not perfectly predict all situations. Now, as for the differences, Newton's Laws explain what happens when large things move slowly (large being relative, even a tiny ball bearing follow Newton's Laws almost perfectly- here large means "more than a few million atoms"). What Einstein predicted, and has been backed up by many experiments, is that light moves the same speed in any reference frame, and that nothing can go faste...

In general relativity, a black hole is defined as a region of spacetime in which the gravitational field is so strong that no particle or radiation can escape. In the currently accepted models of stellar evolution, black holes are thought to arise when massive stars undergo  gravitational collapse , and many  galaxies  are thought to contain  supermassive black holes  at their centers. Black holes are also important for theoretical reasons, as they present profound challenges for theorists attempting to understand the quantum aspects of gravity. String theory has proved to be an important tool for investigating the theoretical properties of black holes because it provides a framework in which theorists can study their  thermodynamics . How Big Are Black Holes? Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amo...

Walking around on the planet's surface, it  looks  and  feels  flat, so they deem all evidence to the contrary, such as satellite photos of Earth as a sphere, to be fabrications of a "round Earth conspiracy" orchestrated by NASA and other government agencies. The belief that the Earth is flat has been described as the ultimate conspiracy theory.  Here is Gleason's flat earth map from 1892 The actual image of flat earth drawn.  There are so many conspiracy based on this,  the air routes of plane,  why antartica is protected by uno.....  How many of you have carefully looked at and studied the U.N. flag? It is quite an interesting flag indeed. In fact, what you probably didn't know is that it uses the flat earth map as its depiction of earth.  Ever notice what is missing in the U.N. flag? Antarctica is missing. In Gleason's map above, notice that there is a white barrier surrounding the earth on the outer edge. This...
