Well,everyone was having a big deep thought.Serina asked the scientist,"Well at first we need to know how we can enter the inter dimension".Scientist replied,"Well its not that easy.To enter inter dimension we need to enter a worm hole,,,,a specific type of worm holes that are rarely found in the universe.Those Worm holes are supremely unsteady and unstable.It changes itself over certain moments.Sometimes it becomes a portal from one place to another,and sometimes it opens the gate towards the inter dimension.And then we will out of the sight of existence of this dimension and we will have the ability to manipulate this dimensions.If we enter,we need to do it at a perfect moment or otherwise we will face big problems.And also,we need to enter the Worm hole after travelling to the past,that means that you need to go to the past timeline and enter and you know thats impossible due to time paradox.And you cant travel through time in the inter dimension due to different physics law the inter dimension has.So its now impossible to save your planet".
This words saddened both Nolan and serina.Bunch of problems were continuously standing in their way.Also finding solution was hard too.Nolan suddenly asked,"Well suppose we travelled through time,can we get out of the time portal exactly at the place that we want?".Scientist replied,"Well,the place from where you will travel,you will come out at the different timeline from the same place".Nolan again asked,"Will we have time before vanishing?".Scientist replied,"You will have like 10 seconds before vanishing".Nolan got an idea.Perhaps the idea which will enhance the last hope of saving the earth.Nolan said,"Can you at first find where the nearest worm hole near us from here?".Scientist did a intensive search and after couple of minutes he found a Worm hole in a galaxy close to andromeda galaxy.And the nearest thing to it is a big massive star and its size was 8-10 times bigger than Sun's mass.That worm hole was damn big in size as well.So Nolans plan was that they will go to that galaxy at first.Then they will select a place near the worm hole. Then they will travel through time at that place close to the Worm hole.Well getting that close to the worm hole was impossible and maintaining a big distance was necessary considering the safety of the space ship as many asteroids roams in near the worm hole.Scientist asked,"We cant use the speed of light immediately after time travelling,it will take atleast a minute to get recharged.And getting vanished wont even take a minute".Nolan said him to listen to the whole plan.He stated that they will use the time machine at a spot not so close or far from the star.Then after returning to the same spot at the past,we will use the normal speed of sound to reach near the region of gravitational time dilation where the time gets totally slow and considering the mass of that star and also I am sure you know that the gravitational force bends the space time, sothe time will definitely get damn slow.5 seconds will look like 50 minutes..And we will use less than a second time to complete recharge.After recharge we will use the speed of light to take us to the worm hole straightly.And then we will have our goal accomplished without getting vanished.Cool huh!
Well,this made the scientist kind of ashmed.The idea was applicable and the chances of success of this plan is 90%.So everyone was set to start the "Mission Back". "We have a planet to bring back at any cost".
