      The length of LIGOs arms are multiplied by reflecting the laser beams between mirrors at each end. I forget the exact number but it is a couple of hundred times at least.

    "What secrets do you think gravitational waves could reveal?"
    Well, I think we should not lose sight of the fact that space-time is made up of time and space, but that space is defined simply by the time it takes to cross a particular distance at a particular speed. Time defines space. We could deduce that there is only time, an energetic physical process of evolution, and that space merely emerges from this process. This debate has been going on now for many years and has not been resolved. So, let's try this idea and see how it might work, but first;-
    I got a warning message yesterday threatening to ban me from commenting for "spamming"! Are we going to let some dumb algorithm stifle scientific debate, or are we going to stop this insanity?
    Please would someone complain and put pressure on to cease and desist? Thank you on behalf of all of us.
    To continue, Consider a light emitter. It emits waves of photons in cyclical numbers, more then less then more then,....well, you get the picture. It seems that no one has ever asked "How?" So, I will make a suggestion. The emission of a single photon is an event. The emission of many photons is many events. So, we observe that the number of events, anywhere is space s cyclical. THE RATE OF EVENTS IS CYCLICAL. This means THE RATE OF TIME IS CYCLICAL, since the rate of events IS the rate of time. Time passes in waves, faster then slower then faster then,....if you catch my drift. Or we might say, the energy that powers all events is wavelike since such a cyclical energy field will produce the effects of what we label as time. THERE IS A CYCLICAL ENERGY FIELD THROUGHOUT THE COSMOS THAT POWERS ALL PROCESSES. (Take gravity, time slows down or loses energy where there is energy right? Do you not think this is clear evidence that time somehow powers the energy of a mass?)
    If there is fundamentally only time, a wavelike energy field, then it is THIS field we are detecting when we detect gravitational waves. Certainly, as time varies, then so does the "size" of space and so the LIGO type arms will do their job in detecting differences in lengths. But we should not lose sight of the fact that we are observing ripples in time.
    This opens up new thinking in our interpretations in science and is worth pursuing. The idea has merit don't you think?
    Well, you did ask, so please don't ban me for comments like this one.

    I just watched a IAS lecture on this, fascinating stuff. They mentioned how big a hit the loss of Arecibo was for the program because Arecibo was tracking lots of pulsars for them. There's the big dish in China now, but they don't get much time on that it seems. It's a really long-term and data intensive project, but I hope we can build up some kind of map because that would be insane for understanding the big structure of the universe and how large a part UMBHs play in it.

    Why does expansion of the universe result in it cooling down? It sounds obvious to be honest, but I guess all Ive ever heard is “it expands and therefore cools down”. I get that in normal physics that works, but I’ve never heard anyone explain the scientific proof behind the whole universe following that same property. Just curious. Thanks and great vid!

      From what I understand, the energy in the universe is constant and when the universe expands, the concentration of energy decreases, thus the temperature decreases

    • @DonDayR
      @DonDayR Год назад +3

      Think of how a camera's flash rapidly looses effectiveness with increased distance from a subject. This "inverse squared" falloff happens across the electromagnetic spectrum including IR and visible light. Expansion of the universe ensures that the process of cooling is not static but is ongoing.

    • @Lektuerekurs
      @Lektuerekurs Год назад +4

      I'm not a physicist. But I guess: 'heat' is stuff moving. In a hot object/liquid etc the small particles move around more vigorously than in a colder one. When everything expands there's less particles per area everywhere. Less stuff moving, less heat per each local point.
      that's my layman explanation for myself at least 😅
      on a 2nd thought the heat would still be inside the universe, just everywhere would feel colder because the heat has to 'warm' a much bigger room. that's my Homer Simpson explanation

    Literally, I came up with this concept in 1982. Waves that are underlying gravity, and how they actually make us fall down onto planets, and planets to suns, and suns to Black Holes, that the concept determined would be at the center of every galaxy. Gravity, thus, is not a pull, but a push. Of the vibrations pushing us and things, from stronger gravity vibrations toward less vibrating places. Their unequal vibrations are gravity.

    They're going to need significantly more points to prove anything, not just pulsars, but observations of them. Maybe landing multiple probes on the surface of multiple planets in the solar system would be a good start, but we also need some observations from at least the next system over.

    10:30 Millisecond pulsar means the pulsar can complete one rotation in a few milliseconds, not that it can rotate a million times in a second.
    If it can rotate a million times per second it would mean its surface is moving faster than the speed of light.

    So gravitational waves travel through space time. But didn’t space-time get created by the big bang? Didn’t it not actually even exist until the big bang expansion happened, and the expansion actually was the creation of space-time? So how does that play with propagation of gravitational waves from the big bang?

    millisecond pulsars do not rotate millions of times per second, but between 100 and 1000 rotations per second. I've read about the fastest spinning neutron stars, and they're rotating over 700 times per second. An object on the surface of such a pulsar is traveling a significant percentage of the speed of light and the neutron star is flattened quite severely into a disc.
    off the internet :
    "PSR J1748-2446ad
    The fastest-spinning neutron star known is PSR J1748-2446ad, rotating at a rate of 716 times per second or 43,000 revolutions per minute, giving a linear speed at the surface on the order of 0.24 c (i.e., nearly a quarter the speed of light)."

Thus, our universe must be extremely older than 13b or 26b yr🤏
