 Is time moving faster we've all heard  the cliche phrase but according to  physics time is actually moving slower  100 years ago we believed that time was  the same for everyone and everything we  were all participating in the same ticks  of the clock every interval of time was  the same as the one before and it moved  forward in a linear uniform progression  however in 1919 Albert Einstein  demonstrated that time is relative with  a theory of special relativity he  discovered that time slows down or  speeds up depending on how fast you move  relative to something else we know that  when you travel faster for instance time  moves slower this is something NASA has  had to account for in their satellites  which move around the Earth at 29,000  km/h the clocks onboard each satellite  ticked slower than identical clocks o   the ground by about 38 microseconds per  day each mic...

 Black holes are one of the strangest things in existence.  They don't seem to make any sense at all.  Where do they come from...  ...and what happens if you fall into one?  Stars are incredibly massive collections of mostly hydrogen atoms  that collapsed from enormous gas clouds under their own gravity.  In their core, nuclear fusion crushes hydrogen atoms into helium  releasing a tremendous amount of energy  This energy, in the form of radiation,  pushes against gravity,  maintaining a delicate balance between the two forces.  As long as there is fusion in the core,  a star remains stable enough.  But for stars with way more mass than our own sun,  the heat and pressure at the core allow them to fuse heavier elements  until they reach iron.  Unlike all the elements that went before,  the fusion process that creates iron  doesn't generate any energy.  Iron builds up at the center of the ...

 What is a science that is the question for  today  and the answer to this question is very  interesting  and that is the word science has been  derived  from a Latin word sanction which means  knowledge  this word science with which we are very  familiar  has basically been taken from our Latin  word  Scientia which means knowledge  that means science is a piece of knowledge  but the question is what type of  knowledge  is it let's see its definition according  to one of the definitions  the knowledge gained through  observations and  experimentations is known as  science the knowledge which is based  upon  the observations and experimentations is  taken as science  other pieces of knowledge which don't fall in  this category  cannot be taken as science as  a science deals with nature it is also  called  natural philosophy the basic ...
