    About black holes

    # A black hole with the same mass as the Sun would have a temperature of about 0.06 millionth of a kelvin. Actual black holes are even larger (at least about three times as massive as the Sun) so their temperature is less than 0.02 millionth of a kelvin. # 1- In classical theory black holes...

    About black holes

    At the core of the Milky Way galaxy, contains a supermassive black hole of about 4.3 million solar masses. Supermassive black holes with a mass between 0.1 million and 10 billion M☉. Some astronomers have begun labeling black holes of at least 10 billion M☉ as ultramassive black holes. Even...

    INFINITY

    ‘'The problem of the exact description of vacuum, in my opinion, is the basic problem now before physics. Really, if you can’t correctly describe the vacuum, how it is possible to expect a correct description of something more complex?'' / Paul Dirac /

    INFINITY

    There is only one "thing" that can be understood as infinite/eternal. And it is the cosmic vacuum that contains billions of galaxies, various kinds of quantum particles (virtual, string, anti-particles, etc.), dark matter, black holes, wormholes, . . . and everything else. These "everythings"...

    INFINITY

    INFINITY Infinity appears in many equations. Examples: 1-For light at constant speed (c) in vacuum, time is "frozen" (eternal situation). 2-When the Schrodinger (Ψ) wave - function ''collapses" the situation is infinite/eternal. 3-Beyond the event horizon of a black hole, time will stop (eternal...

    TIME

    "Time" is stopped: 1- at the event horizon of a black hole gravity 2- at constant speed (c) of light 3- at ''collapse' the Schrodinger (Ψ) wave - function 4- at a "point of singularity" of big bang 5- at the end of accelerating and expanding the universe 6- . . . 7- . . .

    TIME

    John von Neumann said to "the father of information theory" Claude Shannon: " Name it "entropy" then in discussions you will receive a solid advantage, because nobody knows what "entropy" basically is "

    TIME

    Time. The past is fixed and clear. It is impossible to revive the time that has gone into the past. The future is subject to the Heisenberg uncertainty principle: ΔE Δt ≈ ħ/4π. "Time" is created by gravity matter and energy (quantum energy). "Time" is a relative concept. Without gravity and...
