You're right not to believe in time as a medium because time is a just a human concept created to represent the interval over which events occur. Time travel doesn't exist because 1. time doesn't actually exist, and 2. the amount of energy to reverse/progress events would be insane and impractical

well, people always claim the energy would be insane and impractical depending on their level of understanding, in one thread a guy claimed it would be way too much to make a guy go up a line up a hill using a motor and battery. so it's a kinda pointless argument when it's the method of doing things we haven't realized.

There are events that occur all of the time at the micro and macro scale. Think about how many events occur during any given interval, say 1 second. The amount of energy you would need to reverse every single event that occurred during that 1 second is unimaginable. Say you want to scale up and go back in time a year. Now you need the energy from 31557600 seconds (a single year). How would you even go about collecting the energy and carrying this out? I understand where you are coming from and usually I would agree. I just don't see any practical way of actual event reversal unless you had an infinite (unknown, incredibly large value) of energy, which may not even be attainable.

nobody is arguing it would work like that, and the energy required to sustain earth for 1 year isn't even that big in the grand scale.
