NASA announced Tuesday, Dec. 14, 2021, that next week's launch of its new space telescope is delayed for at least two days because of a communication problem between the observatory and the rocket. Liftoff of the James Webb Space Telescope is now targeted for no earlier than Dec. 24. Credit: Laura Betz/NASA via AP, File NASA is shooting for next Friday to launch its newest space telescope. NASA Administrator Bill Nelson confirmed Friday that the James Webb Space Telescope will attempt to blast off on Christmas Eve. A European Ariane rocket will provide the lift from South America's French Guiana. The $10 billion Webb—considered the successor to the Hubble Space Telescope—was supposed to soar Saturday, but was jolted by a clamp during launch preparations, resulting in a four-day delay. Then a bad communication link on the rocket had to be fixed, postponing the launch another two days. U.S. and European space officials signed off Friday on the launch date, following one last round of testing. more at link................. LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLL What a great Christmas present if this goes off without a hitch! Finger crossed...go NASA!!

Earth does have a "use by date", as does Sol.

Not at all; This is simply more of your usual dimreeper avoidance for whatever reason/s you have. Your "hunger" red herring has been answered. Perhaps do what I suggested...you know, If you don't believe me go try it. I'll wait for you with my pork chops and salad. 😅 Mathematics is said to be the universal language, at least for an advanced species. The Voyager golden record and the Pioneer Plaque. You don't believe in using all your senses? It may enable you to see further then you do now. You failed to answer the above dimreeper? You also appear to do that a lot. Yep, that's a legitimate proposition worth thinking about. In a similar vane, what about "generation" type star ships? If any advanced Aliens, are on any voyage of discovery through the galaxy, what would be the chances that they are aggressive? Very minimal I suggest, but on the off chance that they are, I suggest they may avoid contact with other reasonably advanced civilisations ( such as us) for fear of damage/retribution on their star ship, that ended their voyage of discovery and all generations on board. Otherwise I envisage a scenario of them landing in some conveneint place, ( not out in the middle of nowhere) and asking the first humans to take me to your leader!!. If any of the unexplained UFO/UAP sightings were Alien controlled, this is what I would suggest would happen...no hiding, no kidnapping, no anal probing, no hiding and flittering in and then flittering out again. On thinking further, perhaps this maybe our own first method of travelling to the stars? (generation type star ships) Particularly if we did observe an extra solar rocky planet similar to Earth. Then we have that other possibility of eventually discovering some sort of warp travel or at least apparent relative speeds approaching light, and setting out and eventually overtaking the generation type star ship that set out a century or so earlier. The mind boggles! In the end, all we can do is wait and see. When will we discover that ETL does exist? Some are suggesting within the next decade or two. That life will not be any advanced being, more likely some basic simple life either in the Ocean's of Europa, or Enceledus. I hope I'm still around when that happens.

I've explained admirably why we need food and energy, and that the opposite would mean hunger. If you don't believe me go try it. I'll wait for you with my pork chops and salad. Not really interested in the other cryptic nonsense about torches and light...which is rather funny....funny peculiar, not funny ha ha.

As do I. But your attitudes with this now, among your other silly claims and agenda driven attitudes, all fail the scientific method that as yet we have absolutely no evidence for any life off this Earth. Unless of course you have evidence of your own capture and anal probing by some visiting Alien life from elsewhere? Yeah, me too. I have the second Ashes cricket test to watch between Australia and England...and a couple of cold tinnies on ice!

More unsupported claims. Or perhaps if I am wrong, we'll see you in Stockholm next November? 😁 More crap. The "Heat Death" of the universe is simply one hypothetical among a few. https://en.wikipedia.org/wiki/Heat_death_of_the_universe "The heat death of the universe (also known as the Big Chill or Big Freeze)[1] is a hypothesis on the ultimate fate of the universe, which suggests the universe would evolve to a state of no thermodynamic free energy and would therefore be unable to sustain processes that increase entropy. Heat death does not imply any particular absolute temperature; it only requires that temperature differences or other processes may no longer be exploited to perform work. In the language of physics, this is when the universe reaches thermodynamic equilibrium." Opposing views[edit] "Max Planck wrote that the phrase "entropy of the universe" has no meaning because it admits of no accurate definition.[28][29] More recently, Walter Grandy writes: "It is rather presumptuous to speak of the entropy of a universe about which we still understand so little, and we wonder how one might define thermodynamic entropy for a universe and its major constituents that have never been in equilibrium in their entire existence."[30] According to Tisza: "If an isolated system is not in equilibrium, we cannot associate an entropy with it."[31] Buchdahl writes of "the entirely unjustifiable assumption that the universe can be treated as a closed thermodynamic system".[32] According to Gallavotti: "... there is no universally accepted notion of entropy for systems out of equilibrium, even when in a stationary state."[33] Discussing the question of entropy for non-equilibrium states in general, Lieb and Yngvason express their opinion as follows: "Despite the fact that most physicists believe in such a nonequilibrium entropy, it has so far proved impossible to define it in a clearly satisfactory way."[34] In Landsberg's opinion: "The third misconception is that thermodynamics, and in particular, the concept of entropy, can without further enquiry be applied to the whole universe. ... These questions have a certain fascination, but the answers are speculations, and lie beyond the scope of this book more at link............... https://en.wikipedia.org/wiki/Big_Bounce https://en.wikipedia.org/wiki/Big_Crunch https://en.wikipedia.org/wiki/Big_Rip

Dunno. Dunno. You have me there also. Is there? Can you show me a reputable reference/link, observational data/experimental data, of these life forms? Intelliget or otherwise? single cell or multi cell? any life off the Earth at all? I wait with anticipation.

No, we cannot be certain of that: Please read previous answer. No, we cannot be certain of that. See above. It is redshifted beyond the capabilities of all our instruments. And of course when that limitation is reached, it appears frozen just this side of the EH, and we never see it cross that horizon into oblivion. eg: If we were viewing an intrepid astronaut, that is what we would see...or alternatively never see. But take another frame or reference, (like the astronaut) and he certainly crosses and is spaghettified and broken down into his most fundamental particles. Try 380,000 years post BB...before that the universe was opaque. At present we see the CMBR at 2.7K. Not sure what any of this has to do with your still unsupported claims. That is absurd, and gobblydook. Gravity is geometry, spacetime curvature. DE is the place mat for the unknown force accelerating the expansion of the universe over the largest scales. That's why scientists call it dark...same applies to DM. https://en.wikipedia.org/wiki/Chronology_of_the_universe https://wmap.gsfc.nasa.gov/universe/bb_tests_cmb.html https://www.amnh.org/learn-teach/curriculum-collections/cosmic-horizons-book/cosmic-microwave-background-radiation

We havn't got a validated QGT as yet. Is it? where is your evidence? your reference? your reputable link? I mean is there any reason why we should take your word for it? Surely you understand that your answer can be questioned? Hallelujah!!! (just the same old, same old.)

Others have addressed your "reasonings", which certainly is not evidence as you have been informed. I am not a scientist, and would rather question what I see as gobblydook. Whether you understand it or not is no skin off my nose, but the forum does require evidence. OK, let's focus on your following rhetorical statement.....(which I believed I answered correctly) Please show me evidence, not just words, reputable links, observational data, experimental results etc, that support your unquestionable answer that DE indicates the existence of a singularity as defined by infinite quantities?

No you havn't...you have provided rhetoric, unsupported WAG's, unevidenced, and most probably going on your other posts, agenda driven. You mean all those pesky knowledegble cosmologists/astronomers/physicists, that are able to understand that while GR predicts singularities as defined by infinite density and spacetime curvature, it also fails us at those levels? Yep, the singularity as defined by the lack of application of our laws and GR, certainly at this time exist. Scientists and the scientific method, (you should look that up) understand that sometimes questions have no known answer, at any one particular time, but reject your apparent answers that you believe cannot be questioned.

These men self produced their "domestic terrorists" defining moment by not obeying isolating laws, and going out having a good time, disregarding all and sundry, due to there own selfishness, and have now infected 100's. What do you suggest? Personally, I say lock em up! From my link..... "More than 200 COVID-19 cases have already been linked to the nightclub. Anyone who attended the nightclub between 9pm on Wednesday, December 8 to 3am on Thursday, December 9 has been deemed a close contact, and must immediately get tested and isolate for seven days". There may well be more, and sadly the possibility of death.

https://www.9news.com.au/national/coronavirus-update-nsw-man-fined-thousands-for-breaching-isolation-and-travelling-to-newcastle-nightclub/74f9b68a-53ad-4169-a33f-f8eb97d60ea2 Man fined $10,000 for breaching isolation and starting Newcastle outbreak Two men have been fined for allegedly breaching self-isolation orders and travelling to Newcastle, the epicentre of the New South Wales Omicron outbreak. The men, both 20 and understood to be known to each other, were told to self-isolate from December 8 after coming into close contact with a COVID-19 patient. But they allegedly headed to the Argyle House nightclub on Wharf Road later that night. more.... That's a deserved hefty fine in any one's language. Non payment of course means jail time.

I just did. We need energy to exist...we get that energy from the Sun fundamentally, and via food as an extension. Without that energy we hunger and die. That applies to any living organism. Our advanced Alien friends would know that. So why would we need to explain hunger via maths? There are other senses in lieu of a whole species being deaf, (and you once again playing your silly philosophical games 😉) and if that was the case, probably refined to greater degrees of perfection. Unlikely because I don't believe any advanced species, if they did exist, and if they could reach us, would really want for too much. Plus I have a personal theory [OK an hypothesis) that as any life evolves past a certain threshold of intelligence and technological advancement, any aggressive tendencies would diminish. Even at our own questionable state of intelligence and technological advancement, if we found some form of intellgent lifeforms or otherwise, in the Ocean's of Europa, we wouldn't start blasting them with missiles or nuclear weapons. And I'm more certain that in the very small chance that some distant advanced species maybe aggressive, it would not/should not, stop us exploring and becoming a true space-faring civilisation. Afterall the Earth does have a "use by date" (as does the Sun) and if our species could survive extinction for a couple of billion years or so, our descendants may find another, possibly even better home. Thank you. While I wasn't giving that too much thought, my question would be can chemosynthesis ever take place without a parent star? from your link......................... "In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis". <<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>> OK, so the process does not require energy directly from the Sun or another star, but then we must ask, where does the carbon melcules and methane and other nutirents come about. I'm sure you know that answer as well as I. We were all born in the belly of stars. Carl Sagan.

Your perspective is actually wishful thinking, brought on to support some sort of agenda that was relevent from your first post. You have no evidence other then rhetoric and in some cases rhetorical gobblydook. +1 A good example of what studiot was inferring. DE simply is a place mat for whatever it is that makes the universe accelerate in its expansion rate. In science (as oppossed to supernatural and paranormal nonsense) It is better to have questions that can't be answered at any particular time, rather then answers that can't be questioned., as per your many conclusive statements throughout this thread.

No bias, just the BB cosmology, instead of your WAG's. Of course you are...that's why you are in speculations. Actually wrong again. We cannot as yet say the universe is finite or infinite, other then quite a bit bigger then our observable universe. https://www.esa.int/Science_Exploration/Space_Science/Is_the_Universe_finite_or_infinite_An_interview_with_Joseph_Silk https://www.scienceabc.com/nature/universe/is-the-universe-infinite.html "There remains no clear or definitive evidence that the universe is either finite or infinite, although there are some intriguing arguments and proposed theories on both sides. The great thing about this mystery, however, is that due to the nature of the universe, we may never be able to truly know the answer!" Although you are speculating within the speculation forum, the rules state that you are still required to offer evidence to support your claims or reputable references.

Had the Moderna booster shot today after previous two Astra Zenaca shots.....As per previous injections, no reactions.

Interesting concept but highly unlikely I suggest.

t=0 means "zero time" In essesnce, it shows that space and time are dependent on each other, and that the BB did not occur in time or space (as we know them) but that time and space (as we know them) evolved at the BB. There was no "before the BB" Plus of course the the singularity as defined by infinite concepts has been generally rejected, rather simply a singularity as defined by the lack of coverage by our current laws and GR. Speculate as much as you like, but that's all it is...speculation.

Yes of course, t=0, equates to the instant of the BB, the point is our laws of physics and GR, only predict back to t+10-35econds. (I always thought it was t=10-45th until corrected. Sounds rather like mythical gobblydook to me.

And as is the case with that small noisy minority in Sydney. Needed to take a bus ride yesterday, to see a couple of old school mates for dinner and the usual piss up. While restrictions have relaxed mostly in NSW because of our 93% fully vaccination rates, it is still required to wear masks in public transport. After a couple of stops this great big hulking fool boarded the bus and plopped himself one seat from me. He didn't have a mask. Thankfully the bus was half empty, so I made eye contact with him, muttered loudly "f%$#&@# Idiot" and moved to another seat.Just before my stop and getting off, I told the bus driver, but not sure what action was taken Thankfully also my favourite drinking hole at Bondi, is exercising its rights, ( given to them by me and other members) to exclude all unvaccinated people from the club until further notice, members or non members.

We need energy to exist...we get that energy from the Sun fundamentally, and via food as an extension. Without that energy we hunger and die. That applies to any living organism. Our advanced Alien friends would know that. So why would we need to explain hunger via maths? Maths and other means as illustrated...... https://voyager.jpl.nasa.gov/golden-record/whats-on-the-record/ What are the contents of the Golden Record? The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim.

Clearly space, time, spacetime are not physical entities. That does not mean they are not real, and validated as real by the effects they have on light, mass, energy, orbits etc. Just as clearly, distance are spacial dimensions that exist in space, and time obviously the 4th dimension. Your distances whatever they are can only occur in space....no space, no distance, no time, no nothing.

On thinking further, I agree. I was actually trying so hard to be nice to dimreeper with his generally cryptic answers, that I failed to take in the full meaning of the exact consequences. 😏 Thanks for the wise words. I get my booster shot tomorrow.

Space and time, (spacetime) are not physical. You have already agreed to that. And yet it has been observationaly verified that light follows the curves and warps of spacetime ( geodesics) and gravitational lensing.
