Mankind has been working indefatigable day in and day out for the development of their species after the creator kick off from Eden Garden brings instantaneously the beginning of consciousness,new inventions,innovative ideas, science and technology.The humanity sojourn begins here.Thanks to our forefathers for not obeying the words of God😊If they did not break the laws, there will be no such thing as this wonderful life💕🌟☀There will be no such thing as heartbroken💔😊This is the positive results of breaking the laws💪💪Even if you don't want them to break the laws we cannot send a time traveler back to the Graden of Eden to ask not to pick the apple from the tree🌲😊 Do not worry in this write-up we're gonna solve how it could be possible on that by using relevant tools and laws.

My question remains do we necessary need to break another laws to travel in TIME🕒We cannot say as of now it will be depending on our situation.Yeah💪....I totally agree on that😁 I just remember we cannot propose every girls in just one formula😂If one's not valid,we'll make sure to apply another formula😂

Coming to our point T.H.White's epic novel The Once and Future King,where a society of ants declares,"Everything not forbidden is compulsory." In other words,if there isn't a basic principle of physics forbidding time travel,then time travel is necessarily a physical possibility.The reason for this is the uncertainty principle.Unless something is forbidden,quantum effects and fluctuations will eventually make it possible if we wait long enough.Thus,unless there is a law forbidding it,it will eventually occur.In response,Stephen Hawking proposed a "Chronology protection hypothesis" that would prevent time travel and hence "make history safe for historians." According to this hypothesis,time travel is not possible because it violates specific physical principles.However,do not worry Einstein's theory allows for the possibility of time travel.

Einstein's theory links space and time into an inseparable unity.As a result,any wormhole that connects two distant points in space might also connect two distant points in time.In Einstein's theory,we have the possible existence of multiple universes,and in the quantum theory,we have the possible means of tunneling between them.And within a new framework called M-theory,we may have the final theory that can settle these questions about parallel universes and time travel,once and for all.The concept of time itself has evolved over the centuries.To Newton,time was like an arrow;once fired,it never changed course and travelled unerringly and uniformly to its target.Einstein then introduced the concept of warped space,so time was more like a river that gently speeded up or slowed down as itt meandered through the universe.But Einstein worried about the possibility that perhaps the river of time can bend back on itself.Perhaps there could be whirlpools or forks in the river of time.

In 1949,Kurt Godel,the great mathematical logician,found an even stranger solution to Einstein's equations.He assumed that the entire universe was rotating.Like the Van Stockum cylinder,one is swept up by the molasses-like nature of space-time.By taking a rocket ship around the Godel universe,you return to your starting point but shift back in time.In Godel's universe,a person can,in principle,travel between any two points in space and time in the universe.Every event,in any time period,can be visited,no matter how distant in the past.Because of gravity,there's a tendency for Godel's universe to collapse on itself.Hence,the centrifugal force rotation must balance this gravitational force.In other words,the universe must spin about a certain speed.The larger the universe,the greater the tendency to collapse,and faster the universe would have to spin to prevent collapse.It is necessary to spin the universe inorder to be possible time travel.

In 1988,with colleagues Michael Morris and Ulvi Yurtsever,Thorne showed that it was possible to build a time machine if one could somehow obtain strange forms of matter and energy,such as "exotic negative matter" and "negative energy."Physicists were at first skeptical of this new solution,since no one had ever seen this exotic before,and negative energy only exists in minute quantities.But it represented a breakthrough in our understanding of time travel.The great advantage of negative matter and negative energy is they make a wormhole transversable,so you can make a two way trip through it without having to worry about event horizons.One problem,however,is that exotic matter(negative matter) is quite extraordinary in its properties.Unlike antimatter(which is know to exist and most likely falls to the ground under Earth's gravitational field),negative matter falls up,so it will float upward in Earth's gravity because it possess antigravity.It is repelled,not attracted,by ordinary matter,and by other negative matter.This means that it is also quite difficult to find in nature,if it exists at all.When earth was first formed 4.5 billion years ago,any negative matter on Earth would have floated away in deep space.So negative matter might possibly be floating in space,far away from any planets.While negative matter has never been seen(and quite possibly does not exist),negative energy is physically possible but extremely rare.In 1933,Henrick Casimir showed that two uncharged parallel metal plates can create negative energy. 

In a Misner space,the entire universe is contained in your bedroom.The opposite walls are all identified with each other,so entering one wall you immediately emerge from the opossite wall.The ceiling is likewise identified with the floor.Misner space is ofetn studied because it has the same topology as a wormhole but is much simpler to handle mathematically.If the wall moves,then time travel might be possible within the Misner universe.

In 1991,J.Richard Gott 111 of Princeton proposed yet another solution to Einstein's equations which allowed for time travel i,e,cosmic strings.Cosmic strings may have a width thinner than an atomic nucleus,but their mass may be stellar and they may extend for millions of light-years in space.If you take two cosmic strings and send them toward each other,then,just before they collide,it is possible to use this as a time machine.First,he found that if you made the round-trip around the colliding cosmic strings,space was contracted,giving it strange properties.We know that if we move around a table,for example,and return to where we started, we have traveled 360 degrees.But when a rocket travels around two cosmic strings as they pass each other,it actually travels through less than 360 degrees,because space has shrunk.(This has the topology of a cone.If we move completely around a cone,we also find that we travel less than 360 degrees.)Thus,by governing around both strings,you could actually exceed the speed of light(as seen by a distant observer) since the total distance was less than expected.This does not violate special relativity,however,because in your own frame of reference your rocket never exceeds light speed.But this also means that if you travel around the colliding cosmic strings,you can take a trip to the past.Gott recalls,"When I found this solution,I was quite excited.The solution was only positive density matter,moving at speeds slower than the speed of light.By contrast,wormhole solutions require more exotic-negative-density material(stuff that weighs less than nothing)."But the energy necessary for a time machine is enormous."To allow time travel to the past,cosmic strings with a mass-per-unit length of about 10 million billion tons per centimeter must each move in opposite direction at speeds of at least 99.999999996 percent of speed light.We have observed high-energy protons in the universe moving at least this fast,so such speeds are possible".

 Nevertheless,physicists dismissed the idea of time travel because of time paradoxes.

1.Grandfather paradox

2.Information paradox

3.Bilker's paradox

4.The sexual paradox

Time,in general relativity,is represented by a smooth,continuous surface and cannot be torn or ripped.It may change topology,but it cannot simply stop.This means that if you kill your parents before you are born,you cannot simply disappear.This would violate the laws of physics.Let's conclude this write-up by Carl Sagan saying,"Somewhere,something incredible is waiting to be known."🌝
