For real, imagine you’ve built a time machine that can travel through time and at any location on earth! What would you do ?
I would probably go back in time and tell my 8 year old younger self that there’s this pandemic going on, and people are now using Zoom for school and video games are hyper-realistic, but me being be, would just shrug off and go play cricket.
Good ol’ times? elementary school was sure fun
However if I took a copy of The Beatles: Here comes the sun music, and sent it just a few weeks before The Beatles ever came up with the song name, and re-created the “here comes the sun” music – which became a hit, then Who created the song in the first place? That seems to be a boot-strap paradox since it existed before it was thought of… In other words, it would be cool to know what grades you’ve “already” gotten on a tomorrow’s test! Imagine being a sorcerer knowing about the outcome of like PSU vs Rutgers 2023 match! (although PSU would most likely win anyway).
In other cases, time travelling is dangerously volatile as even a single “fix” in the past, could change up everything in the present to future, probably causing another war, or maybe new countries, or no humans on earth… well it depends on how far back in time you would go.. The Jurassic period? Civil war? Last month? Next decade ? the choices here are endless
Well, there could be multiple ways to time travel, starting from the ones everyone is doing right now: living 1 second per second, maybe not in math classes where time stops, and the ones hilariously portrayed in movies, like “Bill & Ted’s Excellent Adventure” , and “Back To The Future” ( where time travelling is achieved when the car travels at a speed of 88mph ) and “Doctor Who” ( where a telephone box can pretty much contain everything and itself, and travel any time anywhere.
Realistically, Time travel is more of a story tale than a physics -reality because if time travelling did exist, then the question wouldn’t exist, Also the laws of thermodynamics, and conservation of mass-matter-energy ..etc rules and math. Nevertheless, I think its cool and very mind bending to think about it, especially after 6 terminator movies and countless youtubers just trying to over-analyse movies. Well, minutephysics’s analysis of time travel in shows is quite informative and Vsauce 3’s Casuality loop will keep repeating itself for.. ever?

The future isn’t written yet.
Very cool blog this week! The messages from your future self at the end was a nice touch. Aside from Doctor Who, all the movies and tv shows I’ve watched and books I’ve read that deal with time travel all end up in a big mess where the characters wish they’d never tried it at all. It’s always the type of thing where “you were too busy asking if you could, you didn’t think to ask if you should.” I think if it were ever possible – though we’d have to break physics for that to happen, lol – I think you can count me out. I always appreciate all the pop culture references you put in your posts! Excited to read next week!
Hi Samarth!
This was a very interesting and mind boggling post. I haven’t particularly thought much about time travel outside of the ice breaker questions like “what would you do if you could time travel”. It was also interesting to hear how time travel has sort of been “debunked” by the scientific community as according to physics, it just would not be possible. It still is fun to think about what would happen if we could time travel though! Great post!
Another week and another thought-provoking topic! Whenever I think of time travel, my mind always goes to Stephen Hawking’s time travel party, where he invited everyone to it the day after it happens as a way to say time travel is not possible. But if I had the ability to time travel I probably wouldn’t go to his party, or if I was hosting the party and someone showed up I wouldn’t tell anyone. What will next week’s topic be?
