So a simple but complex question came up in english today. Is time travel possible? I say no and heres why: The future does not exist, we can only predict it. We will never know what will happen in the future or even if there is one. The past is a memory, we cannot change what has already happened, it's recorded in time and can never be undone. The only thing that matters is the present, its the only thing effecting us and the only thing we can change, therefore we cannot time travel.
As you said, The past is a memory, we cannot change what has already happened, it's recorded in time and can never be undone. However, as you posted the quoted post, you must've assumed at that respective point that a person would post something below, something your brain has learned will happen from repetition. However, this only goes to disprove your theory, "We will never know what will happen in the future or even if there is one". Furthermore, your theory on predicting the future doesn't stand simply because of the facts in place that say you can change the future. Assuming we are at point X, and the beginning of the Banana Pie paradox is point Y, we can conclude the following story. You have just invented a time machine, at point X, and are eager to see how it works. You bring a banana pie in case (wtf?). You go back to point Y, the first banana tree, is where you decide to rest. You find another man, who almost kills you with a mighty swing of his Infinity Gauntlet. You dodge, and decide to smash the kid in the face with your banana pie like a badass. He trips over, and destroys the banana tree. Upon the destruction of the banana tree, you can successfully gauge that the banana pie would never have been there in order to make the kid trip and destroy the banana tree. As a result, you would be back at the same exact point in which he swung his gauntlet at you. You could choose to make these events unfold indefinitely, which would mean you KNOW what is happening. We can further continue to speak about the theory of the multiverse, which is as follows. The multiverse (or meta-universe) is a hypothetical group of multiple separate universes including the universe in which humans live. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, the physical laws and the constants that describe them. As good old Sir Isaac Newton said, "And since Space is divisible in infinitum, and Matter is not necessarily in all places, it may be also allow'd that God is able to create Particles of Matter of several Sizes and Figures, and in several Proportions to Space, and perhaps of different Densities and Forces, and thereby to vary the Laws of Nature, and make Worlds of several sorts in several Parts of the Universe. At least, I see nothing of Contradiction in all this". However, there is some discussion on the subject. Multiple universes have been hypothesized in cosmology, physics, astronomy, religion, philosophy, transpersonal psychology, and literature, particularly in science fiction and fantasy. In these contexts, parallel universes are also called "alternate universes", "quantum universes", "interpenetrating dimensions", "parallel dimensions", "parallel worlds", "parallel realities", "quantum realities", "alternate realities", "alternate timelines", "alternate dimensions", and "dimensional planes". The physics community continues to debate the multiverse hypotheses. Prominent physicists are divided in opinion about whether any other universes exist. Some physicists say the multiverse is not a legitimate topic of scientific inquiry. Concerns have been raised about whether attempts to exempt the multiverse from experimental verification could erode public confidence in science and ultimately damage the study of fundamental physics. Some have argued that the multiverse is a philosophical rather than a scientific hypothesis because it cannot be falsified. The ability to disprove a theory by means of scientific experiment has always been part of the accepted scientific method. Paul Steinhardt has famously argued that no experiment can rule out a theory if the theory provides for all possible outcomes. Citation- https://en.wikipedia.org/wiki/Multiverse
You theory about the banana pie is wrong, for 1 big reason. We already agree that you cannot travel back in time meaning that it's not possible to smash the banana tree from which the pie was made.
To simplify, for time travel to be possible, you would have to break down the molecular structure of the object into atoms and rejoins them after creating a whole other dimension break reality
Now, if one of you would like to disect an item into atoms and store them then put them back together, its basically impossible.
Breaking down the molecular structure of a person is called chemical decomposition. HE DEAD. Not impossible, but is a nuclear bomb, HE DEAD.
As for time travel to the future I have no opinion, idk if it’s possible. But time travel to the past is theoretically possible. There is already instances where scientists have been able to make something go so fast that it goes a few milliseconds back in time. (You can research this further if you want, I’m not sure what the exact science was behind it) So I guess theoretically if you can make something go so incredibly fast you could send it back in time. But my best guess is that this would fucking break whichever item you were sending back in time or the entire fucking universe.
I did a bit of research on objects being sent a little bit into the past. Apparently, German scientists found out that every time Mix humped someone, they got approximately 14 milliseconds younger.
Yes, by orbiting around the earth really fast you can experience time "slower" however it just means that you age a bit slower, not that you have gone back in time.
I am obsessed with the concept of time travel, and I think where ever you got this from was... Time travel to the past is impossible. End of story. Anyways, time travel into the future is possible and has already been done. In fact, you did it by traveling approximately 10-30 seconds into the future (depending on how long you spent staring at that face ^^) from when you started reading this to now.
1. Your a slow reader. 2. I cant tell if you were being serious or not but no, that's not time travel.
That is staying put in time, to travel in time you either have to be able to physicly change history or the future which is merely a thought/prediction/idea. In other words the future is not tangible and cannot be physicly changed and the past has already happened and we agree we cannot change it.
If you mean time traveling to the future faster then others, then that is possible in theory. But its a one-way trip. According to Einstien's Theories of Special and General Relativity, the faster you travel, the slower time goes for you. This effect is known as "Time Dilation." And this is very real. Satellites in space have to even account for this especially GPS satellites. Basically the closer you travel to the speed of light, the faster you can travel into the future. In fact, if you could travel at the speed of light (which by the way is impossible), you would see the history of the entire universe until it ends all in an instant.
What I was referring to earlier was time dilation, but using that concept you can theoretically make an argument that if something was able to go so incredibly fast it could have a gigantic dialation in time.
Here's the key, light is not tangible therefore you cannot touch it meaning you cannot physically change it. If you were to traver FASTER then the speed of light you would EVENTUALLY see the origin of the universe (depends on what you believe) If you were to travel the speed of light you would merely see a frozen picture, nothing would move. BUT... because light always comes from different angles you would see SOME movement. This is my theory and i kind of thought as i typed, no research went into this, this is 5 second logic.
