warp drive

We all know that the fastest thing on earth is light but what if we make thing which is 10 times faster than light.....

Albert Einstein - According to  the theory of relativity any object which have mass it cannot go faster than light because it need too much energy but maybe this theory is applicable for the things which is travel in universe but not on the universe....
this universe was formed about 14 billions year ago if the universe would be spread evenly from all four sides after explosion if the universe spread more than the speed of light the it's diameter should be approximately 28 billions light years...
But according to Astronomers it's diameter is approximately 93 billions light years this means that the speed of the spread of space is faster than light it means the principal of theory of relativity not applies on the universe this means that space can spread more than light and can also be shrink....

Warp drive - if we don't make a vehicle running at the speed of light , if we spread the space behind the vehicle with speed of light and interact with the space ahead at the same speed , then our vehicle will actually reach it destination before light without moving... 
if you know about time dilation the you know as we grow at the speed of light , time slow down but nothing like this happens in a warp drive because this vehicle is not moving at the speed of light or faster . It only defeated the speed of light by expanding or narrowing the space . So in this case time will be equal for us 
if we talk about to compress the space the we know that it is possible to do so . According to Einstein the high mass or High amount of energy can compress the space but for the warp drive to work properly we would need to much mass as Jupiter to compress the space.
Actually the problem is how to spread the space . Actually to do this , we need something whose mass is negative it there is such an object , it will behave exactly opposite to the ordinary object ....
For example - if the earth pull an ordinary object on itself , then an object with negative mass will run away from it.

If you kick an ordinary object , it goes away from you , but if you do it with a negative mass object , it will come to you , it is also difficult to imagine such an object ...
Despite this , negative mass also technically possible and at the quantum level we can also get it through the Casimir effect but to make a warp drive a success we need a lot of negative mass ... 
It is possible that in this universe negative mass can simultaneously exist in a considerable amount of exotic matter But it will be very difficult for us to find it because they do not have any effect on the gravitational force ....
That is , such substance will always run away from the celestial bodies , which means that it cannot be around us . This why it is not possible for us to use warp drive....

Even if we assume that somehow we get a large amount of positive and negative mass , then we will have to face lot of difficulties to make the warp drive into reality.

what if we don't have a brain

  The brain is the most complex and important organ in the human body. The brain is made of soft nervous tissues which control all body functions. It is the center of the nervous system in all invertebrates and vertebrates. It is located in the head and functions as the coordinating center of intellectual, sensation and the nervous system. So can we live without a brain? Well, let’s see if it’s possible or not. The brain is divided into two parts: the cerebrum and the cerebellum. The cerebrum controls important functions like our learning ability, emotion, etc. while on the other hand, the cerebellum controls activities such as balance and our muscle movements, etc. But the brain also determines our personality. There are several cases that show that a brain trauma can change someone’s personality. But back to our main question which is “Can we live without a brain?” To understand this, let us look at a case. In 2014, a 24 years old Chinese woman complained in a hospital about her ...

Kardashev scale

  The   Kardashev scale   is a method of measuring a  civilization ' s level of technological  advancement based on the amount of energy  it is able to use. The measure was proposed by   Soviet    astronomer   Nikolai    Kardashev    in 1964. The scale is hypothetical , and regards energy consumption on a cosmic  scale. Various extensions of the scale have since been proposed, including a wider range of power levels (types 0, IV through VI) and the use of metrics other than pure power. Categories  The Kardashev scale has three designated categories, these are: A  Type I civilization , also called a planetary civilization , can use and store all of the energy available on its planet.  A  Type II civilization , also called a stellar    civilization , can use and control energy at the scale of its planetary system. A  Type III ...

What is butterfly effect ?

 In chaos theory, the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state. The term is closely associated with the work of mathematician and meteorologist Edward Lorenz. What is butterfly effect in simple terms ? The  butterfly effect  is an idea that is more commonly used in chaos theory. A small change can make much bigger changes happen; one small incident can have a big impact on the future. The idea started from weather prediction. ... This  term  can be used in areas other than weather. What is butterfly effect theory ? The  butterfly effect  is the idea that small things can have non-linear impacts on a complex system. The concept is imagined with a  butterfly  flapping its wings and causing a typhoon. Of course, a single act like the butterfly flapping its wings cannot cause a typhoon. IS butte...
