Hi Launchpad Astronomy. I have an idea about tired light hypothesis. I’ve always wondered if it’s ever been considered if instead of light losing energy by bumping into particles as it travels through space could it be that light loses energy to the quantum field analogous to the way waves in a fluid lose energy to the medium they are travelling through.

Thank you, for this fascinating video, and details of the intriguing new paper, suggesting that the universe could be almost double the age of 13.8 billion years. I first had a look at this, a few weeks ago, when there were quite a few sensationalist ‘click bait’ videos about this subject. Since then, one of the questions that popped into my head is, well, the universe might not have to be that much older, I don’t want to sound flippant, but what would be wrong with 14.8 billion years? That would at least give some of these very large early galaxies a more appropriate time to form, especially if the rate of galaxy formation was faster in the early universe. I realise, of course, that even that figure would conflict with the measurements of the CMB. I think the best thing to do, is to wait until we get much more data, it seems to me to be too early to be completely revising the age of our universe, particularly by such a huge leap!
@LaunchPadAstronomy Жыл бұрын
Yep, the best fits to the CMB are what’s constraining our age estimates. But we seem to know even less about how the first galaxies formed, which is why I’m guessing the answer may lie down that path.

Thanks for being objective about this. It's unfortunately common in all areas of scientific research to outright dismiss, or refuse to publish material because it doesn't match with pre-conceived ideas, hypotheses, or theories. Maybe it's great, maybe it's garbage... either way, it should be open for discussion. For me, the whole point about publication is to expose the ideas, the research, the data to the world, and see what happens. All too often, the wider public and the media mistakenly seem to consider that just because something is published, then it must be unassailable and "true".

If the universe or should I say the distant galaxies are 26.7 billion years old then why did it take an additional 13 billion years for the Milky Way to begin. It's only 13.7 billion years old. 26.7 - 13.7 = 13 billion years. Why are the galaxies different ages if a big bang happened? Wouldn't galaxies all be the same age after a big bang? I actually know the answer, I just wanted to see if anyone else realized the error in the laws of thermodynamics like I did. I also accurately predicted the old galaxies in the early universe in first book I published 3 months before the JWST was launched and almost a year before they released the first CEERS survey. On page 48 I wrote quote, "James Webb Space Telescope will discover old, fully grown galaxies as far as the telescope can see, further than 13.8 billion light-years away." And that's exactly what the telescope discovered. I knew exactly what the JWST was going to find. There is no tired light. The only reason why I published the books about this is because I tried to tell NASA employees their theories and laws of physics were wrong and even showed them how to fix them but they were arrogant, assumed they were right and I was wrong. The only way I could prove my equations correct was if the JWST discovered fully grown galaxies further than the time when the big bang happened. Then they would have to agree, their theories of gravity, the big bang, laws of thermodynamics and the evolutionary cosmological model they've held with such high regards are completely wrong. But, it's difficult for a dog to change his spots. I came up with a much older date to when the universe began after measuring the mass of a few distant smooth galaxies. One galaxy I measured appeared to be more than 300 trillion years old. Our Milky Way galaxy is really young compared to it. That was the first evidence a big bang never happened. In the first book I published, SECRET UNIVERSE: GRAVITY I explained how gravity is made in large mass and why it doesn't happen in small mass like atoms. I fixed the equations of general relativity and now it agrees with special relativity, quantum mechanics and James Maxwell's field equations. Yes, TOE or theory of everything. The equations of gravity now explain everything, even why some celestial bodies move much faster than what the laws of motion and GR can explain due to their mass, inverse square to other mass, which led to dark matter and dark energy being postulated. The next book I publish will be titled DARK MATTER IS DEAD: MYSTERY SOLVED. The book is already 367 pages long. The books I published are at cost of publishing, printing and shipping. I don't make any money off them. I really don't need your money. I have cancer, had 3 heart attacks and just want my theories to get out to the public before I go again. I can't take money with me when I go. Yes, again, I passed in my sleep July 24th 2021 and days later awoke in ICU. My NDE was a wild experience. I was told to go back to Earth and publish everything into books. It's been 2 years, So far, I've published 48 books. I've got so many more to go in such little time. Did you know the equations of general relativity were wrong? Did you know according to special relativity, quantum mechanics and James Maxwell's equations on EM fields we can't use a telescope to look back in time? That's why the galaxies in the distant universe appear to be similar in mass and brightness as the galaxies in our local neighborhood. That's why I wrote old fully grown galaxies would be found further than 13.8 billion light years away. There is no such thing as look back time. Believing we can use a telescope to look into the past is as silly as believing we can use a microscope to look into the future. Light information happens in an instant when the telescope or observer is contained inside the EM field they're measuring. Peace and love to all.

Light has a minimal mass. Try it (m=E/c^2) so the light gets stretched in wavelength to redder frequencies over distance due to the gravity pulling on it during it's travels so that at some distance the redshifted light sould be too great for us to easily register and measure.

Thank you very very much for telling us the Science behind increased exposure time for distant objects.. Would you please answer one humble question from this fan..? Can we reduce the exposure time of images by increasing the size of primary mirror of our next generation infrared telescopes.. ? Do you see any hope for SAFIR telescope? ... When will JWST image Betelgeuse..? You must have contact with the members of STScI from Baltimore, Maryland. I will be very thankful to you of you reveal when JWST plans to image Betelgeuse.
@LaunchPadAstronomy Жыл бұрын
The short answer is 'yes' as long as the sensitivity is increased as well (which it it is in JWST's case because it's a continuous mirror). JWST has already produced images that are "deeper" than the Hubble Deep Field thanks to simply being larger and more sensitive than HST in the near-IR. But whereas HST required ~2 weeks to obtain its deepest image, JWST got deeper in its 12-hour observation of its first gravitational lens. Imaging Betelgeuse is probably not going to happen with JWST because it's too bright, so it would saturate the detectors even during the minimum exposure time. As for SAFIR, it wasn't included in the ASTRO2020 decadal survey so I doubt we'll see anything with its capability in the next couple of decades. Cheers!

it wasnt THAT long ago, but certainly AFTER the Hubble had been around for a few years, and also the internet, that I was puzzled that nobody was saying that there appears to be a massive black hole in the center of all (most) of the galaxies. Then I was also perplexed that one of the, ahem, greatest discoveries in astronomy of the 20th century by Edwin Hubble was that everything was moving away from each other, and at a faster speed as the universe expanded. HUH ?? . If that was the case, then how come, I told myself, that Andromeda and our galaxy were gonna collide. Made NO SENSE to me. A different statement that WOULD be more accurate would be that a LOT of things in the universe were moving away from each other, and the further away that we look, the faster the universe was moving apart. Then I looked at the red shift statement, and I thought that the red shift was only useful in accuracy, at a certain distance. The further we looked, I thought, the red shift would be skewed with major inaccuracies. Why ? Because of all the bending of space and gravitational lensing etc etc that we see with our most powerful telescopes. I also looked at the cosmic 'web'. And it really proved to me that everything was NOT moving away from everything else. People need to realize, that our understanding of the universe is in its INFANCY, as we have only been making many many many observations for a few YEARS !! And certain 'facts' in the astronomy community, will change and change and change, as we learn more and more. Well I hope I typed this correctly and hope people understand what I mean.

If we got the universe's age wrong who's to say we got the earth's age wrong as well

Amazing that scientists could be so stubborn and dogmatic. Webb told us pretty plainly we miscalculated the age of the universe, yet they won’t budge. No one likes to admit when they’re wrong but damn.

what if i fudge the ratios of stellar matter in theory and tell you it's 57.6 billion years old, and you just haven't looked long and deep enough to see the high order galaxies to prove me right?...

Just wait until they find out the universe is quite a bit older than 26 billion. After all how could that galaxy 10 trillion light years away get that far in only 26 billion years. The universe is much larger than what we can see.
