Our best theory of the universe might be breaking apart! The new data we’re receiving from space telescopes is creating more and more cracks in our current understanding of the universe, and some scientists believe
we could be standing on the edge of the next great revolution in physics. When did the first galaxies really form?
How fast does our universe really move and why are the huge cosmic voids not following the cosmic principles?

    The search for truth requires the humility to admit being wrong and the wisdom of recognizing the brilliance of scientific pioneers despite them being wrong, both are rare gems of humanity.

    Honestly the prospect that the big bang as we know it never happened, but rather that the universe is way older than we can estimate, and there might be things we can never know for sure, is way more engaging and mysterious than the cookie cutter version we have grown acoustumed to.

    A Small question – if we thinik that space is constantly expanding on our data – our data only composes the observable universe which we can see – what if its not expanding but light is just reaching us now and we are mismatching the data? cuz in the video it seems like the observable universe is only expanding thats why the speed is so off its because light is reaching us from different areas that have a huge variety- so that could be possible yall mighta just made a mistake lol (btw dont roast me ik these questions are dumb i just want to know if this video is giving mismatched data cuz it said that it would at the beggining or not)

    Later in the video it also says that the gas came together to form galaxies and whatever but like what if they did form earlier and the process was shortened because of blackholes there must be a reason black holes are at the center of most universes maybe they pulled it in or something yk? thats possible

    We are on the cusp of living in a sci-fi style world folks.
    Everywhere.
    Getting off the planet is still hard.
    On the ground, we are making breakthroughs all over.
    Particle Accelerators as small as millimeters.
    Nueral implants that allow wireless control of technology with thoughts.
    Robotic prosthetics that function like limbs, and then some (detachable and controllable hands),
    Ai,
    Microtech,
    3d printing metal and biological matter, Rabies viruses rewired to monitor targetted nuerogenesis (brain restoration) and targeted reduction of psychological issues,
    synthetic spinal cords,
    drone swarms controllable by a single person,
    flying vehicles left and right,
    sub-orbital flight,
    new understandings in physics, quantum computing, .. the list goes on.
    Some happened as long as 10 years ago, but most have happened in the last year or two, and at the time of this comment, I have read a scientific article succesfully creating the beginning of entire lines of tehcnology that have all changed a ton of sci-fi tropes from maybes, to on the way.

    I dont know if I am scared that it is all happening so suddenly/simultaneously, to be excited to get to experience things I thought would be hundreds of years still in the making, or to be pissed off that I still can't be a mech pilot.
