  • Brian Cox - What Happened After The Big Bang?
    Embark on a cosmic adventure with renowned physicist Brian Cox as we delve into the aftermath of the Big Bang, the universe's most explosive event. This enlightening video uncovers the secrets hidden in the universe's oldest light, the cosmic microwave background radiation, which emerged 380,000 years after the Big Bang. Discover its significance in understanding our universe's infancy.
    Witness the remarkable efforts of the Planck satellite, Europe's mission dedicated to studying this ancient light, enhancing our knowledge of the universe's initial conditions. We explore how the Hubble Space Telescope and the James Webb Space Telescope have furthered this quest, offering us a window back in time to nearly the beginning of everything.
    Brian Cox guides us through the complexities of Einstein's theory of relativity and its implications on the fabric of spacetime. Learn about the fascinating behavior of light and how it serves as a cosmic messenger from the distant past.
    However, our exploration doesn't stop at what we can see. Delve into the enigmatic world of dark matter, a mysterious component of our universe that remains invisible yet significantly impacts its structure and evolution.
    Join us in this captivating exploration of cosmic history, where we not only look at the light from the universe's dawn but also unravel the ongoing mysteries that continue to challenge and inspire our understanding of the cosmos.

      Time here on earth is the flow of electron neutrinos. It does have a counterflow particle from the positive pole. Can you guess what that is? The hydraulic pressure of particles is a clear fact based on electron photography which has been around since 1955. I predicted 40 years later those neutrinos were moving into the galactic bulge and the $270million Ice Cube project in the arctic vindicated my theory. It is hydraulically superior. There are 7 relative spaces with 7 different time spaces. These are boson formats, and the energy intersections of those is where atoms form. I now have absolute proof of this. I now have TOE. This is an infinite universe. Black holes do not exist but appear to thanks to particle recycling.

    I'm wondering, what is the second oldest light in the universe?
    Another question, this time about dark matter. If the environment around the Earth and within the Earth is swimming with dark matter particles, what effect should these have on the way we sense and measure gravity, and does it depend on the density of them, and do we have an idea what their density might be?

    Why do we assume light travels in a straight path when it curves reacting to gravitational masses it passes?

    • @UncleBuZ
      @UncleBuZ 4 місяці тому +2

      Lets ask Chat GPT:
      The assumption that light travels in a straight path is based on the principles of geometric optics, where light is treated as rays that propagate in straight lines. This assumption holds true in many situations, especially when dealing with everyday observations and practical applications. In most everyday scenarios, the effects of gravity on light are negligible, and treating light as straight rays is a convenient and accurate approximation.
      However, when light encounters a strong gravitational field, such as that produced by a massive object like a star or a black hole, its path can be curved. This phenomenon is described by Einstein's general theory of relativity, which predicts that gravity can bend the path of light. According to general relativity, mass and energy in the universe curve the spacetime around them, and this curvature affects the trajectory of light passing through that region.
      The bending of light due to gravity is known as gravitational lensing. It has been experimentally confirmed through observations of astronomical phenomena, such as the bending of starlight around massive celestial objects. The classic example is the observation of light from distant stars passing close to the sun during a solar eclipse. The sun's gravity bends the light, causing the stars to appear slightly displaced from their expected positions.
      In summary, while the assumption that light travels in a straight path is valid in many situations, the effects of gravity, as predicted by general relativity, can cause light to follow a curved path around massive objects. This phenomenon is observable in astronomical observations and is a key prediction of Einstein's theory of gravity.

      @@UncleBuZ one more reason we can correctly assume things are not where they are in layman's terms is FRB's are emanating from location unidentifiable because they power through gravitational fields less effected and appear to Be emanating from a blank space.

      Chat GPT: you can save time and space, and just ask AI brah.
      It seems there might be some confusion in your statement, so let me clarify a few points. Fast Radio Bursts (FRBs) are intense bursts of radio waves that last only a few milliseconds. These events have been observed in various parts of the sky, and their exact origins are not always easy to pinpoint. While gravitational effects could play a role in the propagation of electromagnetic waves, FRBs themselves are not necessarily associated with this phenomenon.
      The challenge in pinpointing the precise location of FRBs arises from the fact that they are often observed as transient and brief events. Additionally, the sources of FRBs are not always easily identifiable or are located in distant galaxies.
      In general, gravitational effects on light, such as gravitational lensing, could cause the apparent position of an object to be shifted, making it seem like it's coming from a different location than its actual source. This phenomenon is more commonly observed in the context of distant galaxies or massive objects in space.
      If there have been recent developments or discoveries related to FRBs and gravitational effects that I'm not aware of (as my knowledge is up to January 2022), I recommend checking the latest scientific literature or news sources for the most current information.

      Light always travels in a straight path. In the case of gravitational fields, space itself is "curved" such that light passing through it appears to have curved, even though it traveled through the field in a straight line (from the light's perspective).

    One of the (many) things I don't understand is, if space immediately after the big bang was so hot and dense that it was opaque to light, why are we using light to determine the time of the big bang?
    Also, if you were in your Dodge Caravan traveling at the speed of light and you turned on your headlights, what would you see?

    • @mattieuleveille

      @@gamerxt333 But the photon is traveling at the speed of light, the same as all the photons around it. Since there is no difference in speed, the photons beside would never glow because their light or glow is traveling at the same speed as the subject. The only way that you would see the glow is if it was traveling faster.
      It's just a mental exercise as I really don't know what would be seen, if anything.
      It's like if the photon is traveling at the speed of light and time stops at the speed of light relative to the subject photon, then there is no difference between the age of the first photon from the big bang and one that you saw from a star tonight, again, relative to each other. It's only for things traveling slower than the speed of light that time has any meaning for. Weird, huh?

    It's like puff the magic dragon when these folks speaking about particles. They've been saying the same thing for decades with 0 results actually. There is no case for dark matter to be a particle, and supersymetry is not there. Let's do better let's fund other projects. If you'd like some suggestions on those theory just give a shout. I'm always willing to give a perspective on such things. Good video.
