INTER GALACTIC COLLISIONS

INTER GALACTIC COLLISIONS 

There are many things that we gonna miss in this universe. Just watch and enjoy things we could see.

This video from https://m.youtube.com/results?q=what+will+we+miss
really tells use the happens of our galaxy and inter galactic collisions that we will miss as it happens many  million years later.
Milky way galaxy on which we stand is going to collide to another galaxy in the outerspace which results in a super visual effects.

GENERAL RELATIVITY THEORY

General relativity is a theory of gravitation developed by Einstein in the years 1907–1915. The development of general relativity began with theequivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall isinertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and momentum within it.

Some of the consequences of general relativity are:

• Clocks run slower in deeper gravitational wells. This is calledgravitational time dilation.
• Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercuryand in binary pulsars).
• Rays of light bend in the presence of a gravitational field.
• Rotating masses "drag along" thespacetime around them; a phenomenon termed "frame-dragging".
• The universe is expanding, and the far parts of it are moving away from usfaster than the speed of light.

Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations aremetric tensors which define thetopology of the spacetime and how objects move inertially.

HOW IS IT POSSIBLE?

 

The day before yesterday, Chris was 7 years old. Next year, she'll turn 10. How is this possible?

Do you get it?  Please comment 

CAN YOU SOLVE IT??????

Some tricky problems

1. What is the value of x?
 
      x ^x^x^x^..........=10

2. There are 50 horses in a race track.
     Each time only 5 horses can race.
     After each race the first three fast
     horses are obtained. Minimum how
     many races will it take to obtain the
     first  three fast horses among the fifty.

3. What is the value of h???

         h^3+h^2+ h + 1 = 0

4. Find a
 
    2^a=3^a


   
   
  

CRAZY BRAIN

Some interesting facts about brain.
1. Human brain has a unique capacity to calculate time. That is you can roughly tell how much time has passed after a particular incident.
2. Brain controls all your body parts.
    But if we think logically, brain is also a body part. So brain is the only organ of our body which controls itself.
3. Brain has capacity to read future, that's  why we sometimes feel that the occasion in if we are standing has already happened.

     
     

USE ONLY FOUR

Try these logical problems.
1. Get 31 using only 4 fours with some well defined mathematics operations.
2. Get 19 using only 4 fours with some well defined mathematics operations.
