UN draft plan sets 2030 target to Avert Earth's Sixth Mass Extinction

https://www.theguardian.com/environment/2020/jan/13/un-draft-plan-sets-2030-target-to-avert-earths-sixth-mass-extinction-aoe

We brought forward that there were period of 250 million years of mass extinction on our earth-”Extinction Clock”. There were 80% mass extinctions have the period.

See Dayong Cao, “Times of Mass Extinctions Drew The Cross And HeTu” https://meetings.aps.org/Meeting/APR24/Session/OD01.9

We develop MEST-TPC/MEST-AI to test a cross-scale “steep–turning–flat” structural pattern across galaxies, lensing, CMB, and selected micro-domain datasets—publishing controls, reproducible pipelines, and falsifiable predictions on candidate invariants and long-term Earth-risk questions.

我们提出对偶张量不变性与结构场拟合框架（MEST-TPC/MEST-AI），在星系、透镜、CMB 与微观数据中检验“陡峭—拐点—平缓”的跨尺度结构形态，并以可复现对照研究追踪两项候选不变量及其对太阳系结构与灭绝周期问题的可证伪预测。 

AEEA Research Team advances a falsifiable cross-scale program grounded in a proposed Dual Tensor Conservation/Invariance principle. Building on this idea, we develop a computable structural-field fitting framework (MEST-AI / MEST-TPC) using a small family of comparable structural kernels (constrained tanh / logistic / arctan forms). Under unified uncertainty treatment and explicit control models, we test structural signatures across public datasets including galaxy rotation curves, strong gravitational lensing, CMB cold/hot spots and void profiles, and selected micro-domain scattering and high-energy spectral data.

Our working hypothesis is that nature may share a common cross-scale morphology—steep–turning–flat—with turning-point metrics that can be stress-tested and falsified. We further test whether the Solar System resides near a turning-point regime of the Milky Way, whether Solar System dynamics exhibits measurable flattening residuals under controls, and whether such turning-point environments can amplify periodic perturbations relevant to long-term Earth risk. We treat “~250 Myr extinction periodicity” as a testable statistical claim, publish reproducible pipelines, and invite independent replication.

AEEA 研究团队正在推进一条可证伪的跨尺度路径：以“对偶张量守恒/不变性”为核心原理，发展结构场方程与可计算拟合框架（MEST-AI / MEST-TPC），并在星系旋转曲线、强引力透镜、CMB 冷斑/热斑与空洞剖面，以及部分微观散射与高能谱数据中进行系统检验。我们提出自然界可能存在跨尺度的共同结构形态——陡峭—拐点—平缓，并在多数据域中寻找其一致的“拐点指标”与候选不变量（two candidate invariants）。

进一步地，我们提出并检验：太阳系可能位于银河系结构拐点附近，太阳系内部或存在速度/残差平坦化迹象；地球所处位置可能使轨道系统更易出现周期性扰动。由此出发，我们把“约 2.5 亿年灭绝周期及其与太阳系—银河系时间尺度的关系”作为重点检验对象，用统计鲁棒性测试与对照模型区分相关与因果，并以可复现发布作为研究底线。 

We propose a falsifiable working hypothesis: dark-sector effects may be represented as an effective description of spacetime structure/background dynamics, modeled as a background-wave/medium-like term within a structural-field framework. In this view, ordinary matter and the dark-sector contribution jointly shape the effective mass–potential profile of galaxies, giving rise to a quantifiable turning-point scale.

We further hypothesize—and will test under explicit controls—that orbital systems near such turning-point regimes may exhibit enhanced sensitivity to periodic drivers, producing statistically identifiable perturbation signatures (e.g., secular drift of orbital elements, spectral enhancement, or systematic residual patterns). If supported, this offers a candidate mechanism pathway linking astrophysical environments to long-term Earth-risk questions; if not, we will publish clear constraints and failure boundaries. 

我们提出一个可证伪的工作假说：暗部门效应可被视为时空结构/背景动力学的一种有效表述，并在结构场框架下用类“背景波/介质项”进行建模。在这种表述中，暗部门与普通物质共同决定星系的有效质量—势能分布，从而形成可量化的结构转折尺度（turning point）。

我们进一步提出并将检验：在星系结构转折区附近，轨道系统可能对外部或内部周期性驱动更敏感，表现为统计上可识别的扰动增强（例如轨道要素的长期漂移、频谱增强或残差结构变化）。如果该效应成立，它为“天体环境变化—地球长期风险”的研究提供一种候选机制路径；若在严格对照与不确定性传播下不成立，我们同样将给出明确的约束与失败边界。

  如何理解大灭绝周期

1，          建立质能时空系统理论，几乎所有的可观测物理量都可以归纳为质能时空。每一个事务都有自己的质能时空系统。

2，          建立质能时空算法。

3，          成功拟合旋转曲线和引力透镜。

4，          解释暗物质和暗能量是时空结构和时空力。

5，          发现宇宙普遍存在的三大结构。

6，          研究太阳系三大结构与暗物质的关系。

7，          我们假设类木行星是时空中心，这个假设得到NASA新观测数据的支持。 

See Cao, Dayong, J03.00008 ”My Idea that Jupiter Has A Spacetime (Gas AS Liquid Fluid ) Center Was Supported By New NASA Observations of Jupiter”

https://meetings.aps.org/Meeting/SES24/Session/J03.8

8，          类地行星是质能中心，类木行星是时空中心，如果我们假设时空中心是暗物质，那么类木行星就是暗物质行星，类木行星领域的小行星和彗星是暗物质小行星和暗物质彗星。

9，          我们假设6600年前，导致恐龙灭绝的是暗彗星和暗小行星，即外太阳系的小行星或彗星。这个假设得到证实。

10，  总结，周期生物大灭绝来源于质能时空平衡系统的周期性突发再平衡，这不仅是物理系统，也是社会形态和生命系统共同存在的现象。

How to Understand the Mass Extinction Cycle

1. We developed the Mass–Energy–Spacetime System Theory.
   Nearly all observable physical quantities can be categorized in terms of mass, energy, space, and time. Every object, event, or process has its own mass–energy–spacetime system.

2. We developed a mass–energy–spacetime algorithm.

3. We successfully fitted galaxy rotation curves and gravitational lensing data.

4. We proposed that dark matter and dark energy can be interpreted as spacetime structures and spacetime forces.

5. We identified three fundamental structures that appear widely throughout the universe.

6. We investigated the relationship between the three major structures of the Solar System and dark matter.

7. We hypothesized that Jupiter-like planets are spacetime centers. This hypothesis has been supported by new NASA observations.

“My Idea that Jupiter Has a Spacetime (Gas as Liquid Fluid) Center Was Supported by New NASA Observations of Jupiter”

https://meetings.aps.org/Meeting/SES24/Session/J03.8

8. Terrestrial planets are mass–energy centers, whereas Jupiter-like planets are spacetime centers.
   If we hypothesize that spacetime centers are dark matter, then Jupiter-like planets may be regarded as dark-matter planets. Under this framework, asteroids and comets in the regions associated with Jupiter-like planets may be regarded as dark asteroids and dark comets.

9. We hypothesized that, approximately 66 million years ago, the objects that caused the extinction of the dinosaurs were dark comets or dark asteroids—that is, asteroids or comets originating in the outer Solar System. We argue that this hypothesis has subsequently received observational support.

10. In summary, periodic biological mass extinctions originate from periodic episodes of sudden rebalancing within mass–energy–spacetime equilibrium systems.
    This phenomenon is not limited to physical systems; similar processes of structural imbalance, sudden adjustment, and rebalancing may also exist in social systems and living systems.

The probability of displacement and period of wave are the space-time. The black hole and its dark planet (dark comet) is made from dark atom. The dark nucleus is made from the dark photon and the dark neutrino, and the dark muon is around it. The dark nucleus has a nuclear energy of the space-time; the black hole radiate the dark proton and the dark neutron like the dark wave (no accretion). We find the dark comet difficultly. But when it impact our earth, it will produce a special ``nuclear explosion'' which will be produce by the nuclear energy of the mass-energy of stone of earth and the nuclear energy of the space-time of the dark comet together. We can not find its reliquiae of the dark comet. But we can check the abundance of iridium and 'shocked' quartz in geological samples around the world. The paper suppose that the Chicxulub Asteroid was the dark comet who Impacted and triggered the mass extinction at the Cretaceous-Paleogene Boundary. (1) S=P(r)=f2. According to the Benford's law, (2)T=P(t)=ln(1+1t)=ν. Among it, S: the quantum space, f: the amplitude, r: the displacement, T: the quantum time, t: the period, ν: the frequence, P: the probability function. (3) E′ψ=iℏ∂ψ∂t. (4) m′ψ=−iℏ∂ψ∂t(∂x)2. (5) E′′ψ=m′′ψc′2,(c′2=−(∂x)2(∂t)2). Among it, E′ψ: the energy of dark wave, m′ψ: the mass of dark wave, E′′ψ: the nuclear energy of black hole, m′′ψ: the mass of black hole, c′: the velocity of dark wave, ψ: the Wave Functions.

Mass, Energy, Space And Time System Theory---MEST A way to help our earth

POSTER

Abstract

There are two danger to our earth. The first, the sun will expand to devour our earth, for example, the ozonosphere of our earth is be broken; The second, the asteroid will impact near our earth. According to MEST, there is a interaction between Black hole (and Dark matter-energy) and Solar system. The orbit of Jupiter is a boundary of the interaction between Black hole (and Dark matter-energy) and Solar system. Because there are four terrestrial planets which is mass-energy center as solar system, and there are four or five Jovian planets which is gas (space-time) center as black hole system. According to MEST, dark matter-energy take the velocity of Jupiter gose up. So there are a lot of asteroids and dark matter-energy near the orbit of Jupiter-the boundary. Dark matter-energy can change the orbit of asteroid, and take it impacted near our earth. Because the Dark matter-energy will pressure the Solar system. It is a inverse process with sun's expandedness. So the ``two danger'' is from a new process of the balance system between Black hole (and Dark matter-energy) and Solar system. According to MEST, We need to find the right point for our earth in the ``new process of the balance system.''

Breakup of a long-period comet as the origin of the dinosaur extinction

Abstract

The origin of the Chicxulub impactor, which is attributed as the cause of the K/T mass extinction event, is an unsolved puzzle. The background impact rates of main-belt asteroids and long-period comets have been previously dismissed as being too low to explain the Chicxulub impact event. Here, we show that a fraction of long-period comets are tidally disrupted after passing close to the Sun, each producing a collection of smaller fragments that cross the orbit of Earth. This population could increase the impact rate of long-period comets capable of producing Chicxulub impact events by an order of magnitude. This new rate would be consistent with the age of the Chicxulub impact crater, thereby providing a satisfactory explanation for the origin of the impactor. Our hypothesis explains the composition of the largest confirmed impact crater in Earth’s history as well as the largest one within the last million years. It predicts a larger proportion of impactors with carbonaceous chondritic compositions than would be expected from meteorite falls of main-belt asteroids.

摘要

希克苏鲁伯撞击体的起源被认为是白垩纪-第三纪生物大灭绝事件的成因，但其起源至今仍是一个未解之谜。此前，人们认为主带小行星和长周期彗星的背景撞击率过低，不足以解释希克苏鲁伯撞击事件。本文表明，一部分长周期彗星在近距离掠过太阳后会因潮汐力而解体，产生一系列较小的碎片，这些碎片会穿过地球轨道。这部分碎片可以将能够引发希克苏鲁伯撞击事件的长周期彗星的撞击率提高一个数量级。这一新的撞击率与希克苏鲁伯撞击坑的年龄相符，从而为撞击体的起源提供了一个令人满意的解释。我们的假设可以解释地球历史上已确认的最大撞击坑以及近一百万年来最大的撞击坑的组成成分。它预测，碳质球粒陨石成分的撞击体比例将高于主带小行星陨石坠落所预期的比例。

Editor’s summary

The geologic boundary between the Cretaceous and Paleogene periods 66 million years ago is marked by worldwide deposits from an impact at modern Chicxulub, Mexico. The impact coincides with a mass extinction that wiped out non-avian di-nosaurs and many other species. Fischer-Gödde et al. measured ruthenium iso-topes in the impact deposits and compared them with multiple classes of mete-orites, which represent potential impactor compositions. They found that the Chicxulub impactor was a carbonaceous asteroid that formed in the outer Solar System. Additional measurements of five other impacts showed that those were due to silicate asteroids that formed in the inner Solar System. —Keith T. Smith

Abstract

An impact at Chicxulub, Mexico, occurred 66 million years ago, producing a global stratigraphic layer that marks the boundary between the Cretaceous and Paleogene periods. That layer contains elevated concentrations of platinum-group elements, including ruthenium. We measured ruthenium isotopes in samples taken from three Cretaceous-Paleogene boundary sites, five other impacts that occurred be-tween 36 million to 470 million years ago, and ancient 3.5-billion- to 3.2-billion-year-old impact spherule layers. Our data indicate that the Chicxulub impactor was a carbonaceous-type asteroid, which had formed beyond the orbit of Jupiter. The five other impact structures have isotopic signatures that are more consistent with siliceous-type asteroids, which formed closer to the Sun. The ancient spherule layer samples are consistent with impacts of carbonaceous-type asteroids during Earth’s final stages of accretion.

6600万年前，白垩纪和古近纪之间的地质分界线由墨西哥希克苏鲁伯地区撞击形成的全球沉积物构成。

这次撞击恰逢一次大规模灭绝事件，导致非鸟类恐龙和其他许多物种灭绝。费舍尔-戈德等人测量了撞击沉积物中的钌同位素，并将其与多种陨石类型（代表潜在撞击体的成分）进行了比较。他们发现，希克苏鲁伯撞击体是一颗形成于外太阳系的碳质小行星。对另外五处撞击事件的进一步测量表明，这些撞击是由形成于内太阳系的硅酸盐小行星造成的。

摘要

6600万年前，墨西哥奇克苏鲁布发生撞击事件，形成了一个全球地层层序，标志着白垩纪和古近纪的分界线。

该层序中铂族元素（包括钌）的浓度较高。我们测量了取自三个白垩纪-古近纪界线遗址、其他五处发生在3600万至4.7亿年前的撞击事件以及距今35亿至32亿年的古老撞击球粒层的样本中的钌同位素。我们的数据表明，奇克苏鲁布撞击体是一颗碳质小行星，形成于木星轨道之外。其他五处撞击构造的同位素特征更符合硅质小行星的特征，这些小行星形成于更靠近太阳的地方。古代球粒层样本与地球吸积最后阶段碳质小行星的撞击相吻合。

Claim 1 — Dual Tensor Conservation / Invariance as a Formal Principle

Claim: A dual tensor conservation/invariance principle can be axiomatized and yields testable observable relations.
Falsifies if: no coherent axiomatization leads to falsifiable implications, or implications fail across independent datasets.
Minimum tests: definitions → propositions → derivations → 3–5 predictions mapped to public datasets.
Verify: /research/themes/dual-tensor-invariance

Claim 2 — Three structural fit-function families are sufficient and comparable

Claim: A small family of structural kernels (e.g., tanh/logistic/arctan with constraints) provides stable, identifiable fits under unified protocols.

Minimum tests: benchmark across datasets with AIC/BIC/CV; identifiability diagnostics; residual spectra.
Verify: /research/themes/fit-function-optimization

Claim 3 — Cross-domain “two constants” exist as candidate invariants

Claim: Two candidate invariants persist across object classes and data sources (with quantified uncertainties and failure boundaries).
Falsifies if: distributions are inconsistent across domains after controls, or scaling relations are not robust to pipeline/uncertainty changes.
Minimum tests: distribution stability; sensitivity analysis; holdout validation; controls against baseline models.
Verify: /research/themes/two-constants-validation

Claim 4 — A universal steep–turning–flat structural pattern appears across systems

Claim: Many systems exhibit a shared “steep–turning–flat” structural morphology that can be quantified via turning-point metrics.
Falsifies if: turning-point signatures vanish under consistent definitions or are explained by selection/threshold effects.
Minimum tests: turning-point detection + null models + sensitivity to definitions and noise.
Verify: /research/methods/turning-point-metrics

Claim 5 — Galaxy outer “smoothing” reflects the structural pattern (not arbitrary fitting)

Claim: Outer flattening/smoothing in galaxy rotation curves is consistent with the structural turning-point model and outperforms controls in residual structure.
Falsifies if: control models match equally well with fewer assumptions; residual structure shows no improvement; parameters unstable.
Minimum tests: matched controls, AIC/BIC, residual diagnostics, multi-start stability.
Verify: /research/domains/galaxies-rotation-curves

Claim 6 — The Solar System lies near a Galactic turning point (testable dynamical signature)

Claim: The Solar System’s location in the Milky Way corresponds to a turning-point regime in the Galaxy’s structural profile, producing measurable dynamical constraints.
Falsifies if: no turning-point metric can be defined robustly for MW profiles, or constraints contradict independent MW measurements.
Minimum tests: MW profile reconstruction under multiple datasets; turning-point detection; uncertainty propagation; controls.
Verify: /research/domains/solar-system/galactic-turning-point

Claim 7 — Within the Solar System, there are hints of velocity-profile “flattening”

Claim: After unified definitions and controls, outer Solar System dynamics exhibits a systematic residual (Δv or equivalent) suggestive of flattening beyond baseline models.
Falsifies if: apparent flattening disappears when using consistent definitions/epochs, or is fully explained by selection effects and known perturbations.
Minimum tests: unify epoch + define r consistently + compute residuals vs baseline; selection-bias controls; publish null results.
Verify: /research/domains/solar-system/velocity-flattening-tests

Claim 8 — Earth may be near a Solar System structural turning point

Claim: Earth’s orbital/planetary environment is near a turning-point regime of a defined Solar System structural profile, implying specific constraints (not post hoc).
Falsifies if: no robust Solar System structural profile exists, or predicted constraints fail.
Minimum tests: define the profile; turning-point metric; pre-registered predictions; controls.
Verify: /research/domains/solar-system/earth-turning-point

Claim 9 — Extinction periodicity (~250 Myr) is statistically robust and linked to dynamical timescales

Claim: A ~250 Myr extinction periodicity (if present) is statistically robust under multiple tests and shows a non-trivial relation to Solar System–Galaxy dynamical timescales.
Falsifies if: periodicity fails robustness tests (multiple comparisons, dating uncertainties, alternative datasets) or coupling disappears under controls.
Minimum tests: rigorous periodicity tests; null models; dating-uncertainty propagation; explicit controls decoupling from dynamics.
Verify: /research/domains/extinction/periodicity-tests

Claim 10 — The 250 Myr extinction cycle vs ~240 Myr Galactic orbital timescale is a testable alignment

Claim: The proximity of ~250 Myr and ~240 Myr timescales reflects a testable alignment rather than coincidence.
Falsifies if: alignment is within expected coincidence rates under plausible uncertainty distributions, or if coupling mechanisms fail.
Minimum tests: uncertainty-aware alignment statistics; Monte Carlo coincidence rates; mechanism constraints.
Verify: /research/domains/extinction/timescale-alignment
