I can’t remember the name right now, and I don’t wanna go look, to escape from their planet, like us? I’m imagining in this scenario that there are squid like people or something, I am wondering what it would take for them to get through the ice, and then be able to escape their gravity well? Do you think there’s anything on the planet that they could use for energy to actually do that, from underwater?

    As for the starlink problems could it one day be feasible to creat a “halo” like ring around Earth for satellites and space stations. Also it would be perfectly set to harvest electricity from the earth’s magnetic field for its own use and more power could be sent back to ground stations via radio/microwave transmitters.

      I would prefer a heat engine to power this. There quite a diferencial of heat at high atmosphere levels. This along with both wind and solar(both are better up there) will generate enough power to both keep the ring charged and able to radiate power down.

      Also NASA did a test of a simple wire copper I think, for seeing power readings from it and it was way more then they thought. So a single loop around earth would be, a lot, but yes adding more options would be better, redundancy, plus more for ion thrusters to maintain stabile orbit and for ships other remote objects and back to earth. Plus it’d have to be an amazing antenna and telescope possibly, if used as an array.

    Besides it's ethical qualities, Space-X's "give and take" approach seems to be a very good model for preventing political tensions among space going nations, impacting space flight and science. Especially since Russia's pull out of ISS showed the first crack! If it was possible to have an Apollo Sojus docking in the cold war we should be able to achieve good working relationships and from time to time cooperations. Those won't stop the militarisation of space, but that makes opportunities for talking to one another all the more important!

Assuming that there was some way that we could actually tap into that power and use some or all of that electricity, would it do anything to Jupiter or Io?

      The energy stolen from the system that you are referring to is taken from the dynamos that create the magnetic field. It wouldn't change orbits. Now if you stole momentum from a body in the form of a slingshot of a craft, this does change the orbit.

      @@robertnewhart3547 That does make sense, but the part that keeps popping up in my head, is that changing electromagnetic fields induce or change currents in the conductors that carry/generate them. Like, if you had a circuit that was a big loop of wire which had two inductors in it on opposite sides, and you messed with the magnetic fields of those inductors, it would change the magnetic fields/currents in the other inductor. (I get that a planet/moon EM field is a lot more complicated, bu still.) If you were drawing enough electromagnetic energy from a dynamo the size of a moon (or bigger) would it change or modify the movement of said dynamo?

      If anything, smaller and solid bodies are less subject to tidal disruption. Any planets that attended stars that are now at the center of the galaxy probably got thrown out of their orbits by the numerous close passes with the BH and other stars, so they would take up independent orbits just like those of the stars. We just would not see them.
      That neglects the question of whether there _are_ any planets there. The oldest stars formed from material without elements from which rocks and water can form.
      There is Trantor, of course. The newer novels mentioned it being some distance from the true center of the galaxy, if memory serves. I've not seen the new series on Apple TV. But, I think a fine up-to-date interpretation would be for it to be a "rogue planet" without a true sun, but the Imperial Palace (the only open ground remaining) is lit by numerous nearby stars.

    I had a nightmare where I got pulled over by a gay cop and I refused to hand over my license & registration. I guess because he was wearing a rainbow pin & tight shorts I should try that stupid "sovereign citizen" crap. Instead of shooting me like a normal cop, he came over to the passenger side and started pleading with me through the slight crack I'd left in the window. He was trying to calm me down, and started talking about normal stuff like black holes & dark matter. In fact he kinda looked like... You. That's when I realised I had fallen asleep listening to this show. I woke up so terrified I just had to type it out. Me? "sovereign citizens?" GAAAAHHHH

    4:45 inflation how is it possible, that inflation came to be? not just economists need to rub their eyes and gasp in astonishment!
    for the cosmic one, the explanation is in rocket science and electro-tec, maybe.
    in an electric conducting circuit, there is the internal resistance of the battery and the external resistance of the loop. the max power flow in Watts is attained if R_int = R_external; it is called "power adaption".
    in rocketry, the photonic(impulse transfer)rocket is the one with the highest ISP and speed!
    in the early blinks of the Big Bang, the electromagnetic and the weak force were still united. When a state/condition was reached so that "power adaption" between particles with inertia and quanta without inertia happened then a 3D-Photon rocket ignited and a short time later fizzled out again. it could have happened more than once. Another way to try to explain it is to say that in the early times, there were short peaks in opacity ( opacity = 1/transparency ).

    By the way, as these 6 red dots (old galaxies) recently discovered in the James Webb space telescope imagery point out, cosmology might have to be revised fundamentally. I bet on the demise of the universally accepted Big Bang theory which depends very simplistically on reversing "mechanically" the expansion of the universe to a ridiculously small initial point of matter that are supposed to have contained all the matter and energy of the universe that exists currently.
    Nope, the universe is not a giant mechanical structure, with gear like watch-precision sequence of events that can be just rewind anticlockwise to its initial state! What a childish perception/analysis of a very sophisticated/complex and fine tuned universe! Time for some grown-up, more scientific cosmology thanks to the James Webb space telescope.

      Nature will reveal the truths about itself, we just have to keep searching. But what alternative theory do you think better matches the observations so far, like the ratios of hydrogen/helium/lithium, the cosmic background radiation and the speed that galaxies are moving away from us? Any other theory has to explain that equally well and make new predictions that are testable.

    Hello Fraser, I like your videos, for the tongue in ckeek way you present them.
    I suspect you like me, find no merit in a ' Dark Big Bang ' theory. I have bee working on an hypothesis, the last part of which is a logical alternative to the ' Big Bang ', ' Inflation ', the ' CMB ', and ' Redshift '. I will stick my neck out and proffer my ' Logical ' ( not mathematical )alternative for scrutiny. If you are interested, I can send you a copy of the whole, which is a logical alternative to the standard model. Kind regards,
    Tony Marsh.
    The Big Bang Death.
    Abstract.
    An hypothesis to challenge the idea of the ‘ Big Bang ‘, being how our universe began, and the idea that the universe is expanding. It is further proposed an alternative explanation for why it is thought that the ‘ Hubble ‘ Red Shift is proof that the universe is expanding. It is also hypothesized that the ‘ Cosmic Microwave Background Radiation ‘, is not proof of the big bang, being the radiation from the leftover heat from the big bang.
    It is proposed that light and all electromagnetic radiation may have a limit to how far it can travel through space. It is also proposed that the universe did not emerge from nothing, but is a dynamic system, in which matter is constantly being created and consumed in a cycle over billions of years. It is proposed that the universe as we observe it has always existed much as it is today, and extends to infinity.
    It is further proposed that the so-called ‘ Big Bang ‘ was not some kind of massive explosion, but is a misconception of what is being interpreted as the ‘ Cosmic Microwave Background Radiation ‘. The ‘ CMB ‘ is the only proof offered for the ‘ Big Bang theory ‘, and this can only be held up by an even more preposterous idea of ‘ Cosmic inflation ‘, inflating the universe from a point of singularity to fill the whole of space in a minute fraction of a billionth of a second.
    I believe that the CMB is not evidence of the big bang, but is due to some other phenomena.
    Background.
    Big Bang Theory.
    The current widely accepted view of how the universe came into being, is the ‘ Big Bang ‘ theory, where from a sub-atomic singularity, an immensely hot dense plasma emerged. It is said that this tiny speck of plasma, then inflated to fill the whole of the universe in less than a fraction of a billionth of a second. From then on, the universe is said to have expanded at an exponential rate over 13.8 billion years to the present date.
    It is estimated that the universe now extends to around 46 billion light years across, but the accepted view of the cosmological community is that the ‘ Big Bang ‘ was at 13.8 billion years ago, which is as far back as we can see. This means that there are 9.2 billion light years of the universe beyond what we can see.
    Even though this is the accepted view, there are many problems with this model, in that observations do not match up with predictions.
    It is a mystery why early galaxies are smoother than predicted.
    It is a mystery why the universe is so homogenous.
    It is a mystery why there is thermal equilibrium throughout the universe without causal contact, which is referred to as the ‘ Horizon ‘ problem. The way that the thermal equilibrium is explained, is by the theory of cosmic inflation, which logically, is an impossibility.
    The theory has no answer to Dark Matter, Dark Energy, or gravity.
    Cosmic Microwave Background Radiation.
    According to the standard model of cosmology, the ‘ CMB ‘ is the background radiation that was emitted at the ‘ Big Bang ‘ and is the heat left over which was spread out throughout the universe.
    This is a contradiction in terms, as inflation is said to have to have happen to dissipate the heat evenly throughout the universe. If the hypothetical phenomenal heat of this unbelievably small singularity was spread out throughout the universe in a fraction of a billionth of a second, there would be no heat left over, because it had all been dissipated to produce the thermal equilibrium that is observed today.
    In the relativistic cosmological model, it is explained that the reason why the CMB can be viewed at the same distance in every direction, is because the ‘ Cosmic Microwave Background Radiation ‘, is said to exist throughout the universe, due to the heat of the plasma that existed at the ‘ Big Bang ‘, being distributed evenly during the fraction of a second inflationary period following the ‘ Big Bang ‘.
    Looking at it logically, it is impossible for the ‘ Big Bang theory ‘ to be correct, for the following reasons.
    The theory is based on two very unlikely if not impossible assumptions, first is that it is possible for all of the billions of tons of matter that makes up all of the matter in the universe being able to emerge from a singularity smaller than an atom. The second is that it is possible for this tiny hot dense singularity could inflate to the size of the universe in a fraction of a billionth of a second.
    This led me to look at the problem from another perspective logically, and to propose the following hypothesis, that simply and logically describes how the universe works , an alternative to the ‘ Big Bang ‘, and why the universe may be static and not expanding.
    Alternative hypothesis.
    The Big Bang.
    It is hypothesized that the ‘ Big Bang theory ‘ is fundamentally wrong, and can be disproved conclusively by the following observations.
    The cornerstone of the big bang theory, is the phenomenon referred to as the ’ Cosmic Microwave Background Radiation ’. This is said to be the afterglow of the heat left over from the big bang, which is claimed to prove it happened.
    However, the fact that the phenomenon called the ‘ CMB ‘ can be viewed at the same distance in every direction, leads to the following. The first conclusion that this would suggest is the only way that this could be true, is if we were at the centre of the universe, which is unbelievably unlikely.
    For the theory to have any credibility, our galaxy should exist at a point anywhere other than the centre. As such, if our galaxy were to exist near the edge of the universe the distance to the CMB should be different in every direction, and not the same.
    The Relativistic cosmological model.
    The counter explanation to this view is the relativistic cosmological model. In this model, it is stated that because the hot dense plasma that emerged from the singularity at the moment of the big bang inflated to fill the whole of the universe, we see back to it now at the same distance, no matter where we are in the universe.
    This explanation when examined closely has major flaws. In the first place, this theory is totally dependent on cosmic inflation, which itself goes totally against all of the known laws of physics. In particular, all the matter that exists in the universe, would have had to travel, not just faster than light, but many times faster than the speed of light.
    If inflation and further expansion has caused the big bang universe to now be at 46 billion light years across, this could mean that earth could be situated anywhere in this area.
    As such, if our earth was situated right at the edge of this universe, there would have to be a different view towards the edge than towards the middle.
    This leads me to postulate that what is being observed, must be due to some other phenomena related to electromagnetic radiation that produces the picture that is termed the CMB, at a distance 13-14 billion light years away.
    I hypothesize, that wherever you are in the universe, even beyond our visible universe, the same view will show the phenomena we call the CMB in every direction, over the same distance, using the same equipment.
    This presents us with a dilemma, in that we need to find an answer to what is causing what we have been observing and calling the CMB. From what I have described, the CMB can’t be the afterglow of any form of big bang, so new research will be needed to find a solution. Two possibilities come to mind as follows.
    It has always been assumed, that light and all electromagnetic radiation, can travel to infinity, and at a constant speed. This has always been my understanding, but now that may need to be reconsidered.`
    Distance and speed of light.
    One possibility is that light, and all electromagnetic radiation, has a finite limit to the distance it can travel, and when it reaches that limit, it diminishes into what we think of as the CMB. This is very possible as we can only measure the speed of electromagnetic radiation over relatively short distances, but when it comes to this radiation that has travelled billions of years, we can only calculate based on perceived parameters, that is to say, all calculations to do with distance, temperature, time and the like are based on the assumption that all electromagnetic radiation travels at a constant speed, which is accepted as being 186,000 miles per second, to infinity.
    I hypothesize that in fact, electromagnetic radiation loses energy and speed proportional to distance and time, and as such would impact on our perceptions of what we see and calculate.
    It would only take a very small drop in energy and speed, to make the calculations we make wildly wrong, and our perception of what we see.
    This would provide a very good argument to support the idea that the universe is not expanding, as it could explain the ‘ Hubble Red Shift ‘, where the light was losing its energy. Depending on how fast energy is lost from electromagnetic radiation, could explain what we see as the CMB, without the need for cosmic expansion. However, this would be for future research.
    Alternative explanation for Red-Shift.

    • @tonymarshharveytron1970
      @tonymarshharveytron1970 ปีที่แล้ว

      Red-Shift is said to be the stretching of the wavelength of electromagnetic radiation, due to the expansion of the universe.
      I hypothesize that the universe is not expanding, and the explanation why the electromagnetic radiation moves to the red end of the spectrum over distance and time, is the speed of electromagnetic radiation drops proportional to the distance it travels.
      As electromagnetic radiation consists of pulses ( quanta ), the frequency is the number of these quanta that pass a given point in a given time, and the time we use is one second. This number is proportional to the distance travelled in one second of time, and it is universally accepted that this is around 186,000 miles per second.
      I propose that over millions of years, energy is lost from this radiation, and the speed at which it travels, decreases proportionally. This means that the number of quanta passing a given point in a given time reduces proportional to the distance travelled and the reduction in speed. Although the distance between each quanta remains the same as when the radiation was originally emitted, its position in the spectrum moves to the lower end because the number of quanta passing a given point in a given time, matches a lower frequency radiation emitted in a more recent period of time.
      Eventually, the frequency would fall to such a low level, the radiation would be absorbed into the fabric of space.
      This would explain the CMB, and would make far more sense of a static universe without any expansion or a big bang with inflation.
      Fabric of Space.
      I will just give a very brief description of this, as it may help to make sense of this hypothesis. It is explained more fully in an hypothesis I have for the composition of the atom.
      It is proposed that there exists, just two incredibly small monopole particles that make up everything that exists in the universe. One is a negatively charged monopole particle called a ‘ Harveytron ‘, which fills every available empty space throughout the universe in a cloud, the ‘ Harveytron Cloud ‘. This cloud is the medium in which electromagnetic radiation is able to travel through space.
      It is also the ‘ Dark matter ‘, and the negative force of repulsion it produces, is the ‘ Dark energy ‘.
      This dark energy is also one of the two components of gravity, which I propose is a force of both attraction, and repulsion.
      The other is a corresponding positively charged monopole particle called a ‘ Dannytron ‘, which in combination with the ‘ Harveytrons ‘, make up all of the atomic nuclei in the universe, and as such, all of the physical nuclear matter throughout the universe.
      Creation of matter.
      It is hypothesized that the matter that makes up all of the nuclear matter in the universe such as the planets etc, is produced by the combination of the two monopole particles I describe.
      It is universally agreed that matter is formed as plasma cools. It is proposed that the early process of matter formation, is the emergence of the two monopole particles that I propose, with an overall massive excess of the negatively charged monopole ‘ Harveytron ‘ particles. It is possible, that this process may be an endothermic reaction.
      As soon as a positively charged monopole ‘ Dannytron ‘ particle forms, it is immediately encompassed by the negatively charged monopole ‘ Harveytron particles. It will be realized that it is not possible for the positively charged particles to exist on their own, whereas the negatively charged particles do.
      If the process of matter formation is endothermic, absorbing heat in the process, thermal equilibrium is explained throughout the universe, without the need for ‘ Causal contact ‘, and solves the ‘ Horizon problem ‘. Also, as I contend that the universe has always existed, thermal equilibrium is a constant with only minor hotspots, in relative terms, due to local events such as supernova and the like
      Cosmic Nucleosynthesis.
      It is claimed that the creation of deuterium and helium, along with trace amounts of lithium and beryllium, in the first 225 seconds after the big bang is proof of the big bang, because in the first moments of the universe, the temperature was billions of degrees. This was so hot that atoms were entirely ionized.
      However, I claim that in a nonexpanding infinite universe, violent events such as supernova and the like, happen regularly throughout the universe creating the conditions for cosmic nucleosynthesis to occur, without the need for the big bang.

    • @tonymarshharveytron1970
      @tonymarshharveytron1970 ปีที่แล้ว

      If it is accepted that the universe has always existed, and was not born all at once in the big bang, most of the problems explaining things such as the ‘ Horizon problem ‘ and the like cease to be a problem. What has caused most of the problems in understanding cosmology, has come from a misconception of the ‘ CMB ‘, and believing that beyond around 13-14 billion light years, there only existed hot plasma.
      We know that throughout the universe, violent events, such as supernova exists, and matter is transformed into a plasma, also it is consumed by black holes, only to be born again in stellar nurseries. This is a perpetual cyclic process, where all matter is not formed in one big event, rather evenly throughout the existing universe.
      Antimatter.
      I believe that this first stage of matter formation produces both the ‘ Antimatter ‘ ‘ Dark Matter ‘, and ‘ Dark Energy ‘.
      The ‘ Antimatter ‘, is the newly combined positively charged monopole particles encompassed with negatively charged monopole particles. This is the embryonic form of Hydrogen, prior to further combinations until enough positive and negatively charged particles cluster together to form a hydrogen atom. At this point the antimatter ceases to exist.
      This easily explains phenomena such as the Muonium. This is just what I have described above, and is likely to be just one of many clusters of the two particles that I propose starting to form nuclear matter, before they are big enough to have enough charge to allow them to eject a photon, and thus have an electron as described in the standard model associated with them.
      Dark Matter.
      The ‘ Dark Matter ‘ is the negatively charged monopole particles on mass in a cloud filling every available empty space throughout the universe trying to repel each other in every direction. Once all of the positively charged monopole particles have been absorbed following further cooling, there will only exist the negatively charged monopole ‘ Harveytron ‘ particles free, in the ‘ Dark Matter ‘ ‘ Harveytron Cloud ‘. The different elements being defined by the amount of positively charged particles contained in the nucleus of each atom. The light elements being formed prior to star formation, the heavier elements being produced within stars over time.
      Dark Energy.
      The ‘ Dark Energy ‘, is the repulsive force created by the negatively charged monopole ‘ Harveytron ‘ particles trying to repel each other in every direction.
      Electromagnetic radiation saturation.
      Another possibility, which may have equal merit, is this. If we consider how many rays of electromagnetic radiation we see when we look back through space, emanating from the vast number of stars and galaxies over that distance and time, there may come a point where the saturation is so great, that they merge into one.
      This could easily explain why we see the phenomenon we call the CMB. This would make sense why it is the same in every direction, no matter where we exist in the universe. It would also explain why the universe has been found to be homogenous in every direction. The distance we can see, may be proportional to the receptive area of the instruments we use to detect the radiation.
      This fact , may explain why the ‘ James Webb ‘ telescope, can see further back than the ‘ Hubble’, due it’s larger mirror, however, it may be that this is the ultimate distance we will ever be able to see. We also have to consider the fact that because the radiation is not coming from one direction, but from every direction, there will be a mass of radiation passing each other in every direction, which must have some influence on what we measure.
      Thermal equilibrium.
      Since the big bang never happened, there won’t have been a massive amount of heat to dissipate throughout the universe. This explains why the universe is a constant temperature throughout, with only minor hot spots due to supernova and the like.
      This completely eliminates the ‘ Horizon ‘ problem .
      Conclusion.
      Apart from the absurdity of everything that exists in the universe emerging from a singularity smaller than an atom, and this singularity inflating to the size of the universe in a fraction of a billionth of a second, the standard model still can’t explain ‘ Dark Matter ‘, ‘ Dark Energy ‘, what is the repulsive force field in the universe that stays at a constant pressure despite the supposed expansion, or ‘ Gravity ‘. It also can’t reconcile the conflict between quantum mechanics, classical physics, and cosmology.
      The fact that the CMB can be seen in every direction, casts serious doubts on the validity of this theory, even though it is explained by the ‘ Relativistic cosmological model ‘. However, The whole ‘ Big Bang theory is based on assumptions that are either wholly illogical or impossible.
      The ‘ Big Bang ‘ theory, and the ‘ Relativistic Cosmological Model ‘, can only be justified by the ridiculous idea of ‘ Cosmic Inflation ‘, which defies logic, and violates all the laws of physics, including matter travelling through the universe at multiple times the speed of light. I contend that these facts, renders this theory disproved.
      The two above hypotheses can explain logically many of the outstanding problems in physics and cosmology.
      Hypothesis proffered by,
      Tony Marsh.
