Good evening Hiranya and The Royal Institution Tibetan singing bowl and energetic water simply super beautiful. Grateful for our Universe and all the unknown yet to be discovered. Exciting, indeed. Thank you. 💜
54:52 anyone who understands anything about the amount of energy water takes to change phase knows that that little, minuscule sound energy you put into that bowl changed, no phase. It caused waves that splashed, but there was no liquid water to water vapor phase change going on there.
What an amazing and informative video thank you Royal Institute! I presume that the light we see is from the past but , from only one certain point of time in the past and on-going from then. Since the universe expands we are lucky to have this feature… imagine though universe if you looked out at it like it was the planet 🌎 earth. Imagine the cycle of life earth , or even a star goes through. Why discount the universe to not have similar features and processes? Maybe great extinctions, ice ages , or radiation ages that promote life ???
Astronomers can only look at the past, as light takes time to travel. Astronomers can see back in time 13.7 Billion years. As astronomers look back in time galaxies are closer together as the universe was smaller then, as the universe is expanding. Beyond is the one that brought the universe into existence. We have studied 20 million stars, and not one can support life as they are ALL too unstable, we are alone. The Sun is the only stable star. Of the 4,100 solar systems studied, not one looks like our solar system, able to support life. Almost all the 4,100 solar systems studied have Hot Jupiters. In normal planetary systems giant planets form beyond snow line and then migrated towards the star. A small percentage of giant planets migrate far from the star. In both types of migrations, any rocky planet like an earth is lost in these planetary migrations. Most stars do not have planets. Many stars are in bi-star systems, thus no earth-type planets. Thus we are alone

Lovely presentation overall. Just a gentle note, with respect, that your Tibetan singing bowl demo shows movement of water, yes, but that is not the same thing as phase change. There is no phase change as suggested in your demo. I presume that your viewers who already have basic physics knowledge will know that, but I hope you will correct this error in notes, and in future episodes to avoid misinforming the general public further. The rest of your talk was great. Best wishes on your continued inspiring lectures!
I'm proud that we are back to objectivism and not every object is physical. That idealism & subjective systems can have eqaul sigma 6 measure on par with physicalism. . And subjectivity Is not idealism or physicalism lol 96% of the universe is subjective properties like hamiltonian oscillating waves or feilds. Gravity is not idealism nor physicalism. I understand the ease of access teaching everything is physicalism plus needs and demands of the era I grew up in but is was wrong, ugly and combative for those of us well connected to how we came to know.what we know think what we think, english orientation and direction that dictates all longitude and latitude that all the world adopted as our elusive prosperity
Hello, Further to my previous comment, I would very much like to offer the following to the whole team. According to my hypothesis, which can unify the various fields of physics, explain Dark Matter: Dark Energy: Antimatter, and two forces of gravity. Also, an alternative explanation for the CMBR: Redshift: The atom: and a nonexpanding universe without any Big Bang or Cosmic Inflation, the following may be of interest. The biggest question that needs to be asked in Cosmology is, Why is it that we can only see back to the CMBR at the same distance in every direction? This presents two problems. Firstly, in a universe that is said to have a beginning in a Big Bang and Cosmic inflation within a billionth of a billionth of a second, dissipating the heat, radiation, and Matter throughout the universe, this would imply that there is a limit to how far this matter has spread. If our Earth is situated anywhere other than the middle of this mass, we should see the CMBR at different distances in every direction. And Yes I have studied the ; Relativistic cosmological model, and what I say still stands. And secondly, since the JWST is proving that there are fully mature galaxies so far back in time that they would have to have existed before the so-called Big Bang, It rules out that the CMBR is not what it is believed to be. Since the only thing that supports the Big Bang is the CMBR, the only evidence for an expanding universe is Redshift and the only way that the Big Bang can be rationalized in a thermally equal universe is by the idea of Cosmic Inflation, which is a physical impossibility, Physicists are going round in circles trying to support the status quo. I would propose that the standard model is flawed at the level of the atom. There was no Big Bang and Cosmic inflation. The universe is not expanding, has always existed much as it is today and extends to infinity, therefore it has no beginning and probably will never end. There are two forces of Gravity, which I have a simple experiment that can prove this, and also proves the existence of Dark Energy / Dark matter. Dark Matter is an incredibly small Negatively charged Monopole particle in a cloud that fills every available empty space throughout the universe. Dark Energy, is the negative force of repulsion produced by the Dark Matter Particles trying to repel each other in every direction. It is also one of the two forces of gravity. The CMBR is not due to the Big Bang, but is a point where electromagnetic radiation reaches saturation. Redshift is not due to the expansion of the universe, but is due to electromagnetic radiation losing speed and energy over billions of years, If you consider over a period of around 14 Billion years, it would only have to lose 1 mile per second every 140,000 years to account for the redshift we see. This and much more is explained in my Hypothesis, ( The Two Monopole Particle Universe ), details of which can be found by typing Tony Norman Marsh into Google If you are interested and can provide me with an email address, I am happy to send you a copy, or it can be read instantly on kindle.. Kind regards, Tony Marsh
Well, The concept of dark matter, the elusive expansion energy and its quantifications, formation of more than 2000 isotopes of 100 elements and its systematic periodicity, the why of formation of galaxy in the way in which they are today, does the gravitational lensing is curvature created or quantum field and its grids created? Etc and thousands of things are missing in this 20th century science projected through the lense of AI based generative correlation model. We need to say, yes, thoughts are good or reaching reality only at those points where possibility of origin with BE condensate pictures (rubidium)are shown., Wishing you the best to reach real 21 st century exposition of what constitutes universe and a unified field transforming in to all these multitudes of existence.
It just occurs to me that "Dark Matter" is a misnomer not only with respect to the "Dark" part, but also with respect to the "Matter" part. We don't know if there's matter there at all. The only thing we do know is that there's *mass*. So "Dark Mass" would be a more appropriate term.
@@DrDeuteron Photons, for instance. Note that with respect to the phenomenon called "Dark Matter", we're _not_ interested in so-called intrinsic mass (aka rest mass, which photons indeed do not have), but rather so-called active gravitational mass (which photons are very much expected to have, though I'm not sure if that's been experimentally confirmed yet).
@@CLipka2373 you're right about photons, and more than one photon can have a mass, e.g., the decay products of positronium--which have total energy 2m_ec^2 and total momentum 0, in the COM frame. But dark matter has to be "cold", which just means kT ~ Mv^2 gives a "v" smaller than the escape velocity of a galaxy cluster (idk what that is, idk guess at least twice the solar system's speed)
The reason why some places on the galactic map are black is not because there are no galaxies emitting light behind them, but because the universe fabric that will carry the light there towards us is very weak. In other words, the tissue there (the structure called ether) has been weakened so much by large masses that it has become a kind of galactic desert
It is mind boggling to see how confidently and seriuosly she presents all these speculations that don't serve any practical purpose in preventing any of the evils experienced on this earth. Decoding the cosmos, wothout targeting PREVENTION OF ALL EVIL in it, is just another means for PERPETUATING them.
I listen to these talks all the time and I’m stunned that with 95% of the matter in the universe unknown yet they go on like they have a clue. If I was only 5% certain in my daily work, I’d be fired. Best they can do but they should be more up front that they effectively in the dark.
They do this because indeed they have a clue. If you do any kind of scientific researches you'd realise there's always a clue that leads you to the answer. And second, being "up front". Yes they are up front and thus you know that 95% is unknown.
..."If I was only 5% certain in my daily work, I’d be fired..." Interesting !! In what scientific field are You working, and what phenomena/aspect are You investigating/researching ?? Best regards.
"95% of the matter in the universe unknown", this is not 100% correct, 95% is dark energy. We also have dark matter. We know in is there. We are still working out what is. Just like gravity, we know it is there, The question is what is it.
@@djsarg7451 we dont know that for certain. It is simply maths and specualtion at this stage. Dark matter/energy are placeholders because we dont know what is going on.
We know what’s going on, there’s something cold and neutral, and there is lots of it. It’s hard to study because it doesn’t couple to any of our gauge bosons.
I hear a mountain of assumptions that lead to foolish conclusions. If shifted spectral lines can mean anything other than source velocity, your entire cosmos falls apart. It could be that matter produces lines differently, because space is different there. The scientific method of establishing constants and refusing to second-guess them is wasting my time. The Strong force was invented to maintain the concept of electric charge. If charge changes when crammed into a nucleus, dark matter then looks silly.
@@DrDeuteron I thought I was clear that the Strong force was invented, because electric charge was already a "known" constant that they could not mentally change. WHY!? Electric charge may very well change when it is crammed into a nucleus, and if I were involved in that time, I would have exhausted that possibility, but I've never read one word of anything like that. I'm referring to protons and the entire cloud of particles involved, positive or negative. It is funny that neutrons are invisible. They could be huge photons of energy needed in the proton changes. You ONLY know what you were told, and that's generations of "people" on a bandwagon. I can show you how math can lie to you, look at my gyro explanation, and this is BASIC mechanics that the bandwagon missed. I remember you now, did you look at the gyro?
@@karagi101 Look at my gyro explanation then come back and make fun of me. PLEASE DO THAT! A million scientists CANNOT be wrong, so you'll be doing me a favor being so smart as you are yelling from a crowd on a bandwagon.
I'm impressed by the quality of presentations from the Royal Institution. Always top notch.

This should become the standard of excellence against which all other RI lectures are measured.
I prefer mister Andrew Szydlo, but this is a very good presentation, too.

This is bizarre indeed - could she mean something else by "phase transition"?
those metaphors are killing it.

Was the glass lens made in-house or is it available from a supplier?
wow, she can explain all day in my book
So gravity; would be the measurement of pressure?
37:13 Super graphic! So, if one were to continue the spiral - extending behind the visible example, would a singularity be reached?
Is anybody else staring at what im staring at..........🫣

Does the 3 body problem not render the calculation of galaxy formation/collision & mutation completely impossible?
It doesn’t. We can use simulations instead of exact equations to see how galaxies form and change.
