  we know that the speed of light is maximum in universe but after some research we found that the expanding of universe is maximum than speed of light. Here the concept of wrap drive come this hypothetics was introduced by John w Campbell in 1957 in his novel island of space. Generally it's a hypothetical space ecraft that help us to move faster than the speed of light for that the space craft have the ability to constrat the particles of universe. It will work by generating warp fields to from a subspace bubble that enveloped the starship. It also distort the local space time and travel faster🚀 than speed of light. But this type of space craft could not be made by our today technology. In 1994 speculate papers produced by physicist Miguel alcubrieree proved in mathematical way that we make a space craft with the concept of  warp drive.  if this Will possible then  we will know more about our universe and will able to discover exahusit matter, white hole e

Hii today I  am going to tell u about liar's paradox in this paradox a person who tell always lie told his friend that he is liar but  telling this he says one truth so how he is liar telling the truth if u know  this answer of pardox then u are genius.Thank u

In general theory of realtivity a white hole is a hypothetical region of space time and singularity  which can not be entered from outside although energy-matter light and information can escape from it. In this way It is reverse of a black hole which can be entered only from the outside and from which energy matter and information  can't escape. white hole appear in the theory of external black hole. Physicstis describe a white hole as a black hole which is reversible of black hole. black hole event  horizon is a sphere of no return a white hole event horizon is a boundary of admission-space time most exclusive curve. But sadly no space craft and telescope do no reach white hole and it is in theory only but with advancement of technology we can find white hole like we find black hole.
