I don’t expect anyone to believe this, but I’m not from here. I was supposed to go back from 2088 to 1926, but something went wrong with the jump. I’ve been stuck in 2026 for a few days now. Everything here feels so strange… it’s like living in a history book that’s falling apart. I just need to find a way back to the stream.

Well I guess I can move something also 
Thanks, 
! Sorry I am still making extra work… again! 
You!
hi, how are you travel in time

Welcome to the board irene2020!
I really do hope your stay here, is a fun & informative one!
Even if you don’t get all the answers you hoped asking questions, It really can be Fun, when/if you read & can find a bit of time to catch up!
Just remember, some questions can’t be answered… Becasue we are talking about time travel, However this may not be one of them. But, also rememeber, not everyone is really one/ aTimetraveler.
I am not saying unknown-P isn’t one, but… if you poke around sometimes under the same person… you might find the questions you seek answers for/from, have been answered sometimes the best they could.
Peek at profiles, skip for unknown-P’s profile pic/letter. If you need any help, I will do my best, when available, trying my hand at being a better overall person… I mean, I always have, but sometimes, a kind word, or nudge by the right person in the right moment… can help another person struggling, find just the path they were looking for all along.
“nudge” What happens when you go back in time?

I want to go back in time…

Many do, we all have reasons that are valid in our eyes. & please take this will all the love I can muster when saying this, rhetorical questions
Is it for the right reasons? i.e. I need quick bucks/turn a little into a lot. Or… cheaper gas, to fill your tank up. I would totally understand this last one the most!" ~QS

In standard quantum mechanics (specifically the Copenhagen interpretation and von Neumann’s mathematical formulation), physical reality operates in precisely two distinct modes:
-
Smooth Evolution (The Continuum): As long as a system is not measured, its state is governed by the Schrödinger equation. This deterministic equation describes the smooth, continuous, and unitary evolution of the wavefunction across continuous space and time.
-
Instantaneous Reduction (The Discrete Event): Upon measurement or interaction, the continuous wavefunction “collapses” into a single observable eigenvalue. This process is non-unitary, non-local, and intrinsically discrete.
How Alternative Frameworks View This Dual Nature
-
Relational & Information-Based Models: These views argue that the continuum represents potentiality (a field of continuous relational possibilities), while the collapse is an event—a localized update of physical information that establishes a concrete record.
-
Objective Collapse Theories (GRW / Penrose): Models like Ghirardi–Rimini–Weber (GRW) or Roger Penrose’s gravity-induced collapse suggest that wavefunctions do not require a conscious observer to collapse. Instead, collapses are actual physical events that occur randomly or when spacetime curvature differences reach a critical threshold, effectively digitizing reality out of an underlying continuous state.
-
De Broglie–Bohm (Pilot Wave): In pilot wave theory, the wave remains a continuous, uncollapsing entity through space and time, while the particles themselves have definite continuous trajectories—avoiding discrete “collapse” events entirely.
A human being is composed of discrete events happening at a high frequency and in order to time travel into the past via quantum theory, that human must be dissolved into the continuum soup and reconstituted in a past era. The no cloning theorem prevents that from happening though…
The No-Cloning Theorem and the unitary nature of quantum mechanics dictate that information cannot be created or destroyed. “Dissolving” a macroscopic system into pure quantum fields scrambles the exact phase, spin, and positional information across endless degrees of freedom. Reconstituting that exact same state would require knowing and reconstructing every quantum state down to the subatomic level without violating thermodynamic entropy.
How General Relativity Approaches Time Travel
In modern physics, time travel scenarios [such as closed timelike curves(CTCs) or traversable wormholes] do not require breaking down the macroscopic object. Instead, General Relativity attempts to bend the underlying smooth spacetime geometry so that a continuous path through spacetime loops back on its own past, allowing the traveler’s bound particles and discrete interactions to remain intact throughout the journey.
Negative energy is required for warping space into a CTC; it violates the null energy condition.
While quantum mechanics theoretically permits the negative energy required by the null energy condition, the governing field equations tightly restrict its scale and duration to subatomic regimes.
If time is a stream then directing part of the stream onto a loop that connects back to itself upstream AKA in the past, might be figured out with topology…
Where the “Stream” Analogy Breaks Down
When you treat time as a physical fluid or stream flowing into a loop, quantum mechanics and thermodynamics introduce fundamental disruptions:
-
Constructive Resonance and Energy Divergence: If field fluctuations (or light rays) loop back to re-enter their own past, they constructively interfere with themselves on every iteration. Topologically, the path exists, but quantum field theory shows that the stress-energy tensor along the Cauchy horizon—the boundary where the CTC forms—diverges to infinity, effectively creating a feedback loop that destroys the geometry.
-
The Entropy Constraint: A thermodynamic system carries entropy. Redirecting a high-entropy “downstream” state into a low-entropy “upstream” past forces a region where the Second Law of Thermodynamics fails locally, creating an unstable boundary where macro-structures decohere.
-
Causal Consistency (Novikov Self-Consistency): Topological solutions to Einstein’s field equations require global self-consistency. Events along a closed loop must be fixed points; the stream cannot “change” the past, as the past already includes the arrival of the looped stream.
Topology allows the theoretical drawing of closed timelines on a global manifold, but local quantum field dynamics act to disrupt or pinch off those loops before macroscopic matter can traverse them.
