• Does normal force depend on the densities of the objects(example: wooden block is on a table, densities of block and table)?
  
• Does light use any route to travel like we drive a car on road?
  
• Is there any formula to find the third side of a triangle with any angle between the sides,Pythagoras theorm works only for right angled triangles.If yes what is it?
  
• What does E=mc^2 state?
  
• Does light have mass?
  
• According to theory of general relativity,the light from a distant star in its path bent due to gravity of sun.Why it was not trapped in sun's orbit (to revolve around the sun)?
  
• Why times runs slowy when gravity is high?
  
• Why time runs slow where gravity is high?

• Why Einstein is said to be the greatest scientist?
  
• What is calculus?
  
• Can ever a beam of light be trapped in an orbit of a star?why?
  
• Does light uses space fabric to travel?
  
• What is the difference between force and energy?
  
• Energy is neither created nor destroyed,can only be changed from one form to another. Then which form of energy is converted into gravitational energy?Gravity is a form of energy, right?
  
• If a heavy stone and a cotton ball are dropped from a height,which falls with more speed? Who proved this in his experiments from the Tower of Pisa?
  
• When 2.5kg weight of hero's hand hits the villain of 80kg,in a movie,the villain moves with 12.5ms-1 and hits a transformer near by.what will be the speed of hero's hand compared to bullet fired from a gun(here speed of bullet is 370ms-1)?
  
• Where can I submit my new theory in Physics?
  
• Energy is neither created nor destroyed but can be changed from one form to another.Then light energy is transformed to which form?
  
• The faster we move the slower the time.WHY?
  
• Why the speed of light is always constant to every observer?
  
• Imagine a place where gravity is slower than on earth,there 1 second is equal to 10 seconds on earth.There, will light cover more distance than that on earth in 1 second? How will you measure its speed?
  
• How can I write my biography in Socratic?
  
• Why a day has only 24 hours?Why shouldn't we make it 48 hours by decreasing number of minutes per hour to 30?What made them choose 60 seconds per minute, 60 minutes per hour,24 hours per day?What is the reason behind choosing this UNIQUE NUMBER?
  
• What is the difference between Astronomy and Astrophysics?
  
• What is dark energy?
  
• Why the distance between mars and Jupiter is changing?
  
• Why do we get body pains after doing vigorous exercise?
  
• Why do magnets attract only iron objects and other magnets?
  
• How far can a beam of light travel if there is no obstruction in its path?
  
• Which books are good to get good knowledge in astrophysics?
  
• A person walked 100 meters towards north and then took a turn of 40° to his left and walked another 100 meters,what is his total displacement?
  
• Is light a wave? Proof?
  
• Is there any phenomenon in astrophysics which doesn't have an explanation?
  
• "Energy is neither created nor destroyed but can be changed from one form to another."An object at rest in space now our earth goes near to it.we know it will be attracted by earth i.e it gets kinetic energy from where does it get this energy?
  
• "Even light cannot escape from blank holes" then how can hawking radiation come out from them?
  
• A free falling object having some kinetic energy hits the ground and comes to rest,now where its kinetic energy has gone?
  
• Why our earth,sun,other stars are in spherical shape?
  
• Can light bend the space fabric?
  
• What is thermodynamics?
  
• How can a boomerang return?
  
• Is there any difference between gravitational force and gravitational energy? What is it?
  
• If any object enters the gravitational field the potential energy of the object in order is transformed into kinetic energy therefore it reaches the ground.what form of energy is converted into potential energy?
  
• "Energy is neither created nor destroyed but can be changed from one form to another"Now,imagine an object at 10m height from ground, so it has potential energy, if earth disappears suddenly what will happen to its energy?
  
• Why does plastic decompose in soil?Is it possible to make an artificial microorganism that feed on plastic?
  
• Imagine,a pond with 100m depth,from the bottom an iron ball is projected.It reached 80m up and when it's about to come down all the water vanished suddenly. Will its final velocity(while coming down)be more than its initial velocity(while going up)?
  
• What is the difference between momentum(m×v) and kinetic energy (#1/2mv^2#)of an object?
  
• Imagine an object that can float it's on a table,take a beaker filled with water.Bring it onto the object and make it upside down,keep it on the object(most of the water should remain in),object floats i.e gets kinetic energy, from where has energy come?
  
• What is the proof for existence of black holes?
  
• What will happen when photons moving in opposite directions collide?
  
• How is light formed?
  
• Is light a particle or wave? Why?
  
• An iron piece get heated faster than water even though same amount of heat energy is applied in both.why?
  
• If we burn a piece of paper using a small flame of match stick, the flame, that is heat and light released from the reaction increases.where do these heat and light energies come from?(energy can be created)
  
• What is there inside metals which is absent in non metals?
  
• What is electricity?
  
• How can electrons in an atom be moving around the nucleus forever?
