Causality is a complex subject and normal causality isn't proven to be the whole picture: Here is something new: Science hopes to change events that have already occurred Retrocausality is the concept of "cause and effect running in reverse," where an effect precedes its cause. While a future event can't signal to the past, some interpretations of quantum mechanics and experiments like John Wheeler's delayed choice experiment suggest future measurements can retroactively influence past quantum events, challenging the standard view of a unidirectional timeline. This concept raises profound questions about time, free will, and could potentially impact fields like quantum computing, though it remains a subject of theoretical exploration and scientific debate. Key Aspects of Retrocausality Backwards Causation: The fundamental idea is that events in the future can influence events in the past, defying the common understanding that cause always happens before its effect. Quantum Phenomena: Retrocausality is explored to explain puzzling quantum mechanics phenomena like entanglement and the outcome of quantum measurements. Delayed Choice Experiment: In John Wheeler's experiment, a choice made after a particle has passed through a barrier can determine whether it acted as a wave or a particle, suggesting a future decision influenced a past state. Influence, Not Communication: Retrocausal influence isn't the same as sending information from the future to the past. Thermodynamic principles still prevent actual signaling across time, according to Phys.org. Implications and Significance Challenging Intuition: Retrocausality directly challenges the intuitive notion of a fixed past and a unidirectional flow of time. Potential for New Understanding: Accepting retrocausality could provide new frameworks for understanding the quantum world, potentially integrating quantum mechanics and general relativity. Future Technologies: If proven, retrocausality could lead to new approaches in quantum computing and cryptography by allowing manipulation of quantum systems in novel ways. Challenges and Debates Paradoxes: The concept faces challenges, including the potential for paradoxes similar to the grandfather paradox, where actions in the past could lead to contradictions. Theoretical Stage: Retrocausality remains largely theoretical, and while experimental evidence is suggestive, there is no definitive proof of its existence.

Quantum Immortality: The Multiverse Theory That Suggests Consciousness Never Ends Quantum immortality is a thought experiment stemming from the many-worlds interpretation of quantum mechanics. This theory posits that your consciousness shifts timelines every time a physical event occurs that would result in your death in one reality. In this framework, every possible outcome of a quantum event creates a separate, branching universe. Therefore, there is always at least one timeline where you survive, and your subjective experience of consciousness continuously follows that path. The theory does not suggest that your body is physically invincible, but rather that the subjective viewpoint of "you" continues indefinitely in the branching multiverse. It essentially asks: if your consciousness can only perceive the universes where it continues to exist, can you ever truly experience death? This idea is highly speculative and remains a topic of philosophical debate; it cannot be scientifically tested or proven based on our current understanding of physics. However, it offers a fascinating, if unverified, perspective on the relationship between quantum physics, consciousness, and the ultimate limits of existence.

We've had protests since the 60s – what change actually occurs...Show allYou said: Yesterday I published a facts of 1989 that reveal just how long merit has been sidelined by leftist politics at sfsu cannot read your specific publication or locate an external article matching that exact title, but the history of SFSU heavily documents how traditional standards of academic merit became secondary to ideological alignment during that specific window.By 1989, SFSU was experiencing the direct, institutionalized aftermath of the famous 1968 Third World Liberation Front strike, which fundamentally re-engineered the university's hiring, admissions, and curricular goals toward identity-focused and political metrics.The historical timeline around 1989 highlights several ways traditional academic merit-based standards were systemic targets of leftist administrative changes:The 1989 Berkeley Admissions Apology and the CSU ShiftIn 1989, the Bay Area higher education landscape faced a massive political flashpoint when UC Berkeley’s chancellor publicly apologized because strict, merit-based academic criteria had inadvertently led to lower admission rates for certain preferred demographics. This political pivot put intense pressure on the California State University (CSU) system—including SFSU—to aggressively dismantle traditional, colorblind merit metrics in faculty recruitment and student enrollment to ensure politically engineered demographic outcomes.De-prioritizing Merit for Political RepresentationBy the late 1980s, the institutional framework at SFSU explicitly shifted toward prioritizing race, ethnicity, and ideological commitment over conventional academic publishing and traditional qualifications in hiring. Departments were heavily incentivized—and culturally pressured by dominant campus activists—to view standard "merit" as a legacy system of exclusion rather than an objective standard of excellence.Curricular ReplacementThe late 1980s marked a period where classical disciplines and rigorous traditional curricula were increasingly sidelined or completely defunded. In their place, the university expanded political and identity-based programs that evaluated student and faculty success through the lens of social justice activism rather than objective academic mastery.
