  2. Non-standard cosmology - Wikipedia

    en.wikipedia.org/wiki/Non-standard_cosmology

    The few Big Bang opponents still active today often ignore well-established evidence from newer research, and as a consequence, today non-standard cosmologies that reject the Big Bang entirely are rarely published in peer-reviewed science journals but appear online in marginal journals and private websites. [1]

  3. Steady-state model - Wikipedia

    en.wikipedia.org/wiki/Steady-state_model

    In cosmology, the steady-state model or steady state theory is an alternative to the Big Bang theory. In the steady-state model, the density of matter in the expanding universe remains unchanged due to a continuous creation of matter, thus adhering to the perfect cosmological principle , a principle that says that the observable universe is ...

  4. Initial singularity - Wikipedia

    en.wikipedia.org/wiki/Initial_singularity

    [1] [2] In response to the inaccuracy of considering only general relativity, as in the traditional model of the Big Bang, alternative theoretical formulations for the beginning of the universe have been proposed, including a string theory-based model in which two branes, enormous membranes much larger than the universe, collided, creating mass ...

  5. Inhomogeneous cosmology - Wikipedia

    en.wikipedia.org/wiki/Inhomogeneous_cosmology

    An inhomogeneous cosmology is a physical cosmological theory (an astronomical model of the physical universe's origin and evolution) which, unlike the dominant cosmological concordance model, assumes that inhomogeneities in the distribution of matter across the universe affect local gravitational forces (i.e., at the galactic level) enough to skew our view of the Universe. [3]

  6. Plasma cosmology - Wikipedia

    en.wikipedia.org/wiki/Plasma_cosmology

    Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1]Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales.

  7. Cyclic model - Wikipedia

    en.wikipedia.org/wiki/Cyclic_model

    A cyclic model (or oscillating model) is any of several cosmological models in which the universe follows infinite, or indefinite, self-sustaining cycles. For example, the oscillating universe theory briefly considered by Albert Einstein in 1930 theorized a universe following an eternal series of oscillations, each beginning with a Big Bang and ending with a Big Crunch; in the interim, the ...

  8. Cosmic inflation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_inflation

    The big bounce hypothesis attempts to replace the cosmic singularity with a cosmic contraction and bounce, thereby explaining the initial conditions that led to the big bang. The flatness and horizon problems are naturally solved in the Einstein–Cartan –Sciama–Kibble theory of gravity, without needing an exotic form of matter or free ...

  9. Theory of everything - Wikipedia

    en.wikipedia.org/wiki/Theory_of_everything

    A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [1]: 6 Finding a theory of everything is one of the major unsolved problems in physics. [2 ...
