A young scientist discovers a time-travel portal in a cave and uses it to alter the past, only to realize the consequences and ultimately learns that the key to shaping the future lies in the present, not the past, with a twist that the portal was created by his future self.
A young scientist who accidentally discovers the portal while conducting research on quantum mechanics and becomes determined to understand its workings and implications for the future.
The young scientist uses the portal to travel back in time to try and prevent a catastrophic event from occurring, only to realize the consequences of altering the past.
The young scientist realizes that altering the past has created unforeseen consequences and decides to use the portal to return to the present and focus on building a better future instead of changing the past. He uses his knowledge from the past to make positive changes in the present and becomes a renowned figure in the field of quantum mechanics. He ultimately learns that the key to shaping the future lies in the present, not the past.
Twist: The young scientist discovers that the portal was actually created by his future self, who was trying to fix the mistakes of the past. He realizes that he must now take responsibility for his own actions and use the portal to shape a better future, rather than trying to change the past.
