My brain hurts. I still don't get how we/they know all this info. HOW do we know we're not just a bunch of Who's living on a dust-speck in Who'ville? :)
Using the scientific method, observations, and experiements, we're able to learn things and each thing we learn is the foundation for further observation and experiments that give us more of the pieces of the puzzle. We would advance faster if people didn't have egos, but despite the egos that slow things down, eventually the community DOES allow for the new understanding based on new data to permeate our understanding and transition to a better, more full understanding based on the most modern data we have. Sir Isaac Newton, the famous English scientist, once said, “If I have seen further, it is by standing on the shoulders of giants.” Of course, Newton wasn't literally standing on the shoulders of giants. Newton was explaining that his ideas didn't come from him alone. He relied on the ideas of those who came before him.
Sometimes they get carried away with protecting the Big Bang and make stuff up. Like the Dark Matter/Dark Energy stuff. They never found either because they don't exist!
The most interesting thing to me is that Webb found 80 supernovae in just one small area of sky. These discoveries will help scientists understand the expansion rate of the universe and the mysterious dark energy.
If the universe supposedly began from one point about 13billion yrs ago, how are there objects 93 billion light years apart? Considering it would take 93 billion yrs for even light to cover that distance how has matter travelled that far?
The universe is expanding at an ever increasing rate. A rate that is faster than the speed of light, which is why there is a horizon beyond which we will never be able to see. And that doesn’t violate any laws. The speed of light is a speed limit only for objects moving through space, not a limit on the space itself
So each time this star goes novae, we see the results. However, because the star is moving outward, each subsequent event happens closer to us than the prior event. Additionally, our technology is improving so we can see further back in time. So if each event that we see is older, than we are watching the universe backwards. Am I making any sense, or am I completely lost?
Keep watching more videos by SOU and other channels and you will develop the language and knowledge needed to fully understand! You can Google terms as well. Learning is fun, especially when it comes to exploring and striving to understand our reality, in which there is so much mystery!
@@Iconoclast1919 Thanks for the tip...I was injecting a very small bit of satire...I work at JPL so I do ask lots of questions. Duck Duck Go is my preferred search engine.
My Latin teacher taught me that the "-ae" suffix was to be pronounced ahh-eeee, in other words, what we in English would call a long i. Just like the ei in German, or the i in like. It drives me a bit batty to hear the long a sound here. But I guess I'm a Ciceronean snowflake, no match for supernovae.
Very cool stuff. Thank you for the interesting listening 👂!! Will dive into more, now that I found you. Been listening to StarTalk with Neil Tyson deGrasse and have ran out of videos to watch. Good timing, good find, GOOD STUFF!! How long can this light be detectable? Is it forever or will it fade away? And whats the universe's ultimate fate? The big rip?
All Good, BUT,, You talked about it, but never mentioned exactly what "The Rate of Expansion of the Universe is.!" - Ha.. I guess i's still a "Secret of the Universe".... hmm
Is it possible that Big Bang could have just have been a very large supernovae event, one of potential endless others, that sparked our universe. Maybe we’re just seeing our “Small” corner of an endless expanse?
CMBR: (Cosmic Microwave Background Radiation): Consider the following: Per QED (Quantum Electro Dynamics, whereby 'em' interacts with the electrons in atoms and molecules) and QCD (Quantum Chromo Dynamics, whereby 'em' interacts with the nucleus of atoms), matter has to exist for 'em' to be given off by that matter. What matter exists in outer space for that microwave 'em' to be seen by us? And 'if' it were from when matter first came into existence during the fairy tale of the 'singular big bang', that 'em' should be long gone by now and should not even be able to be seen by us. BB -> Matter and 'em' are created -> 'em' moves at the speed of light, matter moves more slowly -> (Billions of years go by) -> matter (and us) here ..........................................'em' long gone. (And there is no matter 'out here' yet for any 'em' to come back to us via QED or QCD). AND: RED SHIFT: WARNING: (CONTAINS EXISTENTIAL MATTERS): Consider the following: a. Current narrative: Space itself is expanding. (Even though science does not fully know yet what 'space' actually is nor how it could actually expand). b. But consider: The net effect of solar winds, particles and energy pushing outward from galaxies, (even modern science claims 'em' has momentum), continuously, over a prolonged period of time, with other galaxies doing the same, with nothing to stop them from doing so, would tend to push galaxies away from each other and even potentially allow the cosmic web to form between galaxies. And then, when we here in our galaxy, look at far away galaxies, with other galaxies in between, the net effect of all those galactic interactions would have galaxies furthest from ours move away faster the further those galaxies were from us, including us perceiving a red shift of energy. c. Now, utilizing the scientific principal of Occam's razor, which way is more probably correct? What the current narrative is ('a' above), or 'b' utilizing known physics? * Added note: Plus, 'if' my analysis is correct that our spiral shaped galaxy is collapsing in upon itself, then consider also: d. When we look at solar systems between ours and the center of the galaxy, those solar systems would be getting pulled faster towards the center than ours, hence also seeing a red shift of energy. e. When we look at solar systems between ours and the outer edge of the galaxy, our solar system would be getting pulled faster towards the center then them, hence also seeing a red shift of energy. f. Only if we looked at solar systems adjacent to ours should we see a blue shift of energy (as the solar systems became closer together as they moved towards the center of the galaxy). I also propose looking for blue shifts of energy between our solar system and adjacent solar systems to confirm or deny this current belief. g. But if true, would also add to our observation of seeing a red shift of energy in this universe as our spiral shaped galaxy collapses in upon itself. Of which, not only would species from this Earth have to get off of this Earth before the Sun becomes a red giant one day and wipes out all life on this Earth if not even the entire Earth itself, but species from this Earth would also have to successfully get out of this collapsing spiral shaped galaxy, otherwise, most probably death awaits us all and this Earth and all on it are all just a waste of space time in this universe. All life from this Earth would eventually die and go extinct. Currently, no exceptions. h. QUESTION: Do basically all galaxies eventually collapse in upon themselves? (Which would add to the perceived red shift between galaxies as they all basically shrink in size). Modern science currently states that 'gravity' is matter bending the fabric of spacetime. There is a lot of matter in a galaxy and hence would make a huge dent in spacetime. How could galaxies not collapse in upon themselves if space and time were bent to make it so? Of which also, the progression of galaxies?: 1. How exactly do galaxies form? (The current narrative is that matter, via gravity, attracts other matter. The electric universe model also includes universal plasma currents.) 2. How exactly do galaxies flatten out if gravity is acting on the whole galaxy? (Other forces must also be at work besides gravity for a galaxy to flatten out? Electrical and/or magnetic forces?) 3. How exactly do galaxies become spiral shaped? (At least one way would be orbital velocity of matter with at least gravity acting upon that matter, would cause a spiral shaped effect. The electric universe model also includes energy input into the galaxy, which spiral towards the galactic center, which then gets thrust out from the center, at about 90 degrees from the input. Additionally, with the conservation of energy, as energy moves into the vertical plane from the center of the horizontal plane, energy from the horisontal plane moves to the center of the horizontal plane to replace the energy that moved into the vertical plane. There is also the conservation of angular momentum. As more matter moves towards the center of the galaxy, that portion of the galaxy would speed up relative to the matter towards the outer portions of the galaxy.) Additionally: GALAXY SPIN: (Inner and Outer areas spinning at the same speed): The inner and outer areas of the galaxy are connected via gravitational, electrical, and magnetic energy fields. While moving at the same speed, the inner area has less space to travel whereas the outer area has more space to travel. Hence a spiral shape forms. 4. The natural progression of a galaxy would be to become smaller and smaller. 5. Of which, does all life throughout the entire universe (if other life even exists in the universe besides what is on this Earth, which is most probably true) eventually die and go extinct and the entire universe and all in it are ultimately meaningless in the grandest scheme of things and the entire universe and all in it are ultimately just a waste of spacetime in existence? And even 'if' the current narrative of space itself is expanding, and the entire universe would eventually end in a 'big freeze', wouldn't the end of life itself in this entire universe still occur?
We have yet to discover how old the universe is. It was 13.8 billion light years but that has doubled since JWST was deployed. I believe it to be much, much older. 120-130 billion light years across.
@@Cavillrine36 🤣, "spread the truth, the earth is flat, join our global effort." Religious people think it's what, 6,000 years old? I have a rock that was carved older than that.
Not true. Universe is much longer age for sure. If we see object 13B ligth yaers away, how long time need to make this distance from one point. it is match longer. And this is the distanse 13B years ago not now.
1:53 that is not entirely true supernova are the dramatic final stages of massive stars. Supernovae is a term for all types of supernova’s some of which can be created by small stars like our son that that become gravitationally locked with the corpse of a dead star known as a neutron star or a white dwarf and when even small stars merge with neutron stars, they create supernova‘s, they don’t even have to merge a white dwarf, can go supernova by creating mass from a binary partner that is a type of supernovae that is not created by a massive star
@@JamesLindroos-nj6cn that’s not true nobody knows what gravity even is we don’t even know anything about the Fourth dimension we don’t know if our laws of physics even apply in other universes in the multiverse at best your comment is a hypothesis cuz it’s not even based in fact so it can’t even be a theory
