    The real mind blower is this: We have equipment that can see things that are millions of light years away, but they are in effect looking back in time. If something is 1 million light years away, then the light that is reaching the viewer today left that object 1 million years ago. When you look into the sky at objects, you can never see them at the present time. Even the light from the sun takes 8 minutes to get to your eye. Every time you see the sun, the image is 8 minutes old.

      Of course the same applies to objects that are close, although the travel time becomes incredibly short. It also takes time for signals to travel the nervous system so everything that we see, hear, feel, smell or taste is being perceived as it was in the past. We never really know what the present is like.

    I don't think that people argue the whole alien thing correctly. I don't think the argument is whether aliens exist, it's whether they have visited Earth. Just because there may be a planet with intelligent life on it doesn't mean that they have the ability to travel the universe. And even if they did have the ability to travel the universe, it doesn't mean that they would come to this planet.

      And they, and we, may not last that long relative to the time even for light to travel between the two. Only since about 1900 have we had the technology to use radio waves and we are still a long way from actually traveling any significant distance. Not even 1-1/2 century compared to a galaxy over 13 billion years. (150 vs. 13,000,000,000 years) With luck, our civilization will hold, but we may yet destroy ourselves via nuclear war, run-away climate change, an unbelievable natural catastrophe like the Yellowstone volcano, a sufficiently big meteor strike, radiation for a too nearby supernova, or who knows what.
      We may not even be able to comprehend other intelligent life if we were to find it. Imagine say something like a beehive where the individual bees, like the individual neurons in our brain, are not intelligent, but the system as a whole is.
      On the other hand, the study of abiogenesis (origin of life) is suggesting more and more than atoms just self-assemble into ever more complicated compounds. We have found the various components such as amino acids on meteors. Basic life may be invariably present in any spot in space with the right conditions.

      Satellites are a hoax as well.The Earth is an Encapsulated World/Environment.The Celestial Bodies are All visibly and factually small and they orbit around inside The Earth.There is no room or place for any Satellites.Again there are many Land Towers,which use Electromagnetic Waves or Radio Frequency Waves to create,generate,copy,redirect and transport signals/vibrations All-across The World.Satellites are completely unnecessary.The Ruling Dark Powers use Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers to survey,map out,record and/or broadcast Everything.It is much more easier and far more efficient to use Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers to survey,map out,record and/or broadcast Everything instead of Satellites as Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers are much more closer to The Ground and The Earth and thus:the connection itself is far more closer,faster and clearer.To My understanding creating,building and launching Hundreds,Thousands or more Satellites into Outer Space is incredibly foolish,dangerous and life-threatening.If they ever fall down from the sky,they would be like falling missiles to people.People would be like walking targets.If Satellites truly existed,they would be extremely unwise and unsafe.If Satellites are real they would eventually become too overcrowded up there.Overcrowded Satellites would make Outer Space Travel extremely impractical,uncomfortable,risky,dangerous,fatal and lethal.A Cosmic Wall of floating Satellites would create a Prison World with a Cosmic Minefield - A Barricade of Satellites.People would effectively be trapped on their Own World unable to escape.Sooner or later those same Satellites will fall down if they don't have constant energy/power.If Satellites truly existed,Cosmic Space Travel as We know it would be Impossible or Suicidal.Satellites are a hoax designed in order to convince The Public that Outer Space is real.Satellites don't exist!
      Gravity is not real either.Just think about it.Water cannot be bent.Water is always perfectly level.It does not curve.Water is always Flat on the surface and it can Never be otherwise under any circumstance.If Gravity truly existed and was a fully functioning Force it would be severely limiting,restraining and restricting.According to My knowledge and intuition if Gravity was real it would function like a "Super-glue/Mega-glue Force" perpetually holding Everyone and Everything glued to the ground like Granite.There would be no jumping off the ground,no jumping Creatures,no flying Creatures,no flying Insects,no flying Birds,no Air Travel,no Balloons,no Airships,no Airplanes,no Gliders,no Helicopters,no Rockets,no Drones,no Space Travel,no Satellites and no Spaceships.The sheer "Pressing Power" of Gravity would prohibit,force and ground Everyone and Everything to the ground Forever.Nothing and Nobody would ever be able to leave the ground or to get off the ground Ever.Everyone and Everything in existence would only be able to move Horizontally.Vertical Travel would be Impossible and extremely painful,because of "The Enormous Pressing Force" from Gravity.Everyone and Everything would be Eternally weighted down by Gravity.There would be no escape.Gravity is a false theory designed in order to convince The Public that Outer Space is real.Gravity doesn't exist!
      Outer Space doesn't exist.Earth is the only World there is.There are no other Physical Cosmic
      Worlds out there and there is no Infinite Cosmic Spatial Vacuum Void.Outer Space has "3 Enormous Problems":Problem 1 - Survivability - Cosmic Space is completely and inherently uninhabitable,
      inhospitable and unliveable.This doesn't seem/feel right.If Outer Space truly existed
      it should therefore be completely and inherently habitable,hospitable and liveable.If Outer Space was real it would be 100% welcoming of All-potential Beings,Creatures and Life-forms.This means that Outer Space must be "Breathable",because otherwise Everyone and Everything would immediately and perpetually suffocate and no Life-forms would ever emerge or survive in such a lethal Cosmic Universe.Problem 2 - Cosmic Travel - All-vehicles must push "Something" in order to move and go "Somewhere".In Earth's Atmosphere Automobiles push "Air" to move,Airplanes also push "Air" to move and Cruise Ships push "Water" to move,but Outer Space has no Atmosphere.You cannot travel to/in Outer Space,because The Vacuum of Space neutralizes All-pushing power/travel power.This means that Space Travel is impossible,that No One has ever left The Earth,that No One has ever traveled to Space and that every single Space Mission from the beginning to today is a lie.If Outer Space truly existed it would need to have an "Atmosphere" in order for Outer Space Travel to be possible.Problem 3 - Vast Separation - Celestial Space is just far too tremendously vast as a territory.All-Life-forms are separated,because of the "Humongous Distance" between them.This is not convenient.If Outer Space was real it wouldn't be so gargantuan,because it has to be much smaller and more "Tightly-Knit",so that All-potential Life-forms can locate and
      discover each other.Outer Space is a lie designed in order to convince The Public that Extraterrestrial Beings exist.The total "Inhospitableness" and "Unfeasibility" of Outer Space proves that Outer Space cannot exist,because Outer Space doesn't exist!

    The best comparison I ever came across was: If you shrink the scale of the universe so the Sun would be the size of a marble, the next closest star would be about 400 kilometers away. It's about the distance from Dallas to San Antonio. Or more than the distance from London to Paris. Two marbles. And pretty much nothing in between.

      Satellites are a hoax as well.The Earth is an Encapsulated World/Environment.The Celestial Bodies are All visibly and factually small and they orbit around inside The Earth.There is no room or place for any Satellites.Again there are many Land Towers,which use Electromagnetic Waves or Radio Frequency Waves to create,generate,copy,redirect and transport signals/vibrations All-across The World.Satellites are completely unnecessary.The Ruling Dark Powers use Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers to survey,map out,record and/or broadcast Everything.It is much more easier and far more efficient to use Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers to survey,map out,record and/or broadcast Everything instead of Satellites as Balloons,Airships,Airplanes,Gliders,Helicopters,Rockets,Drones and Land Towers are much more closer to The Ground and The Earth and thus:the connection itself is far more closer,faster and clearer.To My understanding creating,building and launching Hundreds,Thousands or more Satellites into Outer Space is incredibly foolish,dangerous and life-threatening.If they ever fall down from the sky,they would be like falling missiles to people.People would be like walking targets.If Satellites truly existed,they would be extremely unwise and unsafe.If Satellites are real they would eventually become too overcrowded up there.Overcrowded Satellites would make Outer Space Travel extremely impractical,uncomfortable,risky,dangerous,fatal and lethal.A Cosmic Wall of floating Satellites would create a Prison World with a Cosmic Minefield - A Barricade of Satellites.People would effectively be trapped on their Own World unable to escape.Sooner or later those same Satellites will fall down if they don't have constant energy/power.If Satellites truly existed,Cosmic Space Travel as We know it would be Impossible or Suicidal.Satellites are a hoax designed in order to convince The Public that Outer Space is real.Satellites don't exist!
      Gravity is not real either.Just think about it.Water cannot be bent.Water is always perfectly level.It does not curve.Water is always Flat on the surface and it can Never be otherwise under any circumstance.If Gravity truly existed and was a fully functioning Force it would be severely limiting,restraining and restricting.According to My knowledge and intuition if Gravity was real it would function like a "Super-glue/Mega-glue Force" perpetually holding Everyone and Everything glued to the ground like Granite.There would be no jumping off the ground,no jumping Creatures,no flying Creatures,no flying Insects,no flying Birds,no Air Travel,no Balloons,no Airships,no Airplanes,no Gliders,no Helicopters,no Rockets,no Drones,no Space Travel,no Satellites and no Spaceships.The sheer "Pressing Power" of Gravity would prohibit,force and ground Everyone and Everything to the ground Forever.Nothing and Nobody would ever be able to leave the ground or to get off the ground Ever.Everyone and Everything in existence would only be able to move Horizontally.Vertical Travel would be Impossible and extremely painful,because of "The Enormous Pressing Force" from Gravity.Everyone and Everything would be Eternally weighted down by Gravity.There would be no escape.Gravity is a false theory designed in order to convince The Public that Outer Space is real.Gravity doesn't exist!
      Outer Space doesn't exist.Earth is the only World there is.There are no other Physical Cosmic
      Worlds out there and there is no Infinite Cosmic Spatial Vacuum Void.Outer Space has "3 Enormous Problems":Problem 1 - Survivability - Cosmic Space is completely and inherently uninhabitable,
      inhospitable and unliveable.This doesn't seem/feel right.If Outer Space truly existed
      it should therefore be completely and inherently habitable,hospitable and liveable.If Outer Space was real it would be 100% welcoming of All-potential Beings,Creatures and Life-forms.This means that Outer Space must be "Breathable",because otherwise Everyone and Everything would immediately and perpetually suffocate and no Life-forms would ever emerge or survive in such a lethal Cosmic Universe.Problem 2 - Cosmic Travel - All-vehicles must push "Something" in order to move and go "Somewhere".In Earth's Atmosphere Automobiles push "Air" to move,Airplanes also push "Air" to move and Cruise Ships push "Water" to move,but Outer Space has no Atmosphere.You cannot travel to/in Outer Space,because The Vacuum of Space neutralizes All-pushing power/travel power.This means that Space Travel is impossible,that No One has ever left The Earth,that No One has ever traveled to Space and that every single Space Mission from the beginning to today is a lie.If Outer Space truly existed it would need to have an "Atmosphere" in order for Outer Space Travel to be possible.Problem 3 - Vast Separation - Celestial Space is just far too tremendously vast as a territory.All-Life-forms are separated,because of the "Humongous Distance" between them.This is not convenient.If Outer Space was real it wouldn't be so gargantuan,because it has to be much smaller and more "Tightly-Knit",so that All-potential Life-forms can locate and
      discover each other.Outer Space is a lie designed in order to convince The Public that Extraterrestrial Beings exist.The total "Inhospitableness" and "Unfeasibility" of Outer Space proves that Outer Space cannot exist,because Outer Space doesn't exist!

A majority of those stars are not there anymore but the image of those stars dieing has not had enough time to reach us yet. That's why they say that when JWST looks at the sky it's looking further back in time because that's how long light takes to get to us.

It started with the invention of the telescope in 1609. Gallelio was the first to start mapping the stars and looking and recording what was in space. Our instruments send back different types of waves, like sound, infrared, xray, etc. And that helps us fill in information on what these objects are made up of, whether they are moving toward us or moving away, etc. But for all that, we can only see the "observable universe" and will never be able to see beyond it.

    The distances we are talking about are mind blowing. Light travels at 186,000 miles per second. Our sun is approx 93 million miles away and light takes about 8 minutes to travel from the sun to earth, so if the sun were to suddenly vanish, it would take 8 minutes for us on earth to realize.

    For you guys wondering; "How do they know all of this?" Well it basically comes down to trigonometry and use of the laws of nature and physics.
    Here are the 3 main methods to determine distances in the universe.
    1. Parallax
    Parallax is the observed displacement of an object caused by the change of the observer's point of view.
    Here's a fun experiment you can do yourself. stretch out your arm and put a finger up, now close one eye
    and look where your finger is compared to the background, now open the eye and close the other one. When you do this in quick succession
    you'll see your finger jump back and fourth relative to the background. The distance your finger jumps is called Parallax.
    In astronomy, it is an irreplaceable tool for calculating distances of nearby stars but instead of using a finger,
    astronomers use the position of Earth relative to the Sun. In January Earth is on one side of the Sun and six months later,
    it's on the opposite side of the Sun. (remember your jumping finger) LOL
    Parallax enables astronomers to measure the distances of nearby stars by using trigonometry.
    this method is used to measure distances to stars out to about 326 Lightyears.
    For distances which are too large to measure using parallax, astronomers use 'standard candles'.
    Light sources which are further away appear fainter because the light is spread out over a greater area.
    If we know how luminous a source really is, then we can estimate its distance from how bright it
    appears from Earth.
    2. Cepheid variables
    Cepheid variables are a special type of star with a luminosity which varies on a regular cycle. Around
    1908, Henrietta Leavitt discovered that the period of the variability was closely linked to the luminosity
    of the star.
    So, if you time the variability of a Cepheid then you can predict its luminosity. And if you know its
    luminosity and how bright it appears from Earth, then you can calculate the distance.
    Cepheids are used to measure the distance of galaxies out to about 98 million Lightyears.
    Cepheids are what Edwin Hubble used to determine the distances of “nebulae” (ie. galaxies) and
    derive the Hubble law.
    3. Type 1A supernovae
    Supernovae occur when massive stars explode at the end of their lives. A
    white dwarf star in a binary pair with a red dwarf star steals mass from the
    red dwarf until it is too massive to support itself against gravity any more.
    Then its core collapses, starting a runaway nuclear reaction and a bright
    explosion. Because the collapse always happens at the same mass, the
    luminosity of the explosion is always the same. From this known
    luminosity we can estimate the distance.
    Supernovae are very bright - often as bright as all the stars in a whole
    galaxy put together. Because they are so bright, we can see them at very
    great distances, up to around 33 billion Lightyears.
    The disadvantage of supernovae as standard candles is that they don't
    hang around - you have to spot them when they go off, or shortly
    afterwards.

    I always think a fun but enigmatic thought is, that there's possibly beings somewhere out there that can see earth just as we humans can see distant objects millions of years in the past...imagine if they could see earth about 70 million years ago when dinosaurs were here and humans don't exist yet. In reality, everything in space that we have photos of is basically a look into the past like that.

    The nice thing about the one little speck, is that if anything comes toward us from outside the solar system, it's going to miss us unless it's been designed to approach the sun closely, and then find something.
    10:20 Many telescopes of many types have been used to map out the sky, and astronomers have done hard work in charting the sky. The distances were perhaps the hardest thing, but triangles served for the closest things, certain stars serve as standard bulbs on one scale up to (say) 100 million light years, and certain supernovas are standard bulbs on a much large scale, out to billions of light years.
    11:20 The objects emit light on their own, and we detect the light. The light has properties such as its spectrum, and the intensity we detect. Certain stars vary regularly in their intensity. We know what they are like, including their true power emission. We measure the intensity we detect, and use the known power emission to get the distance.
    13:00 It's this point where I think cosmologists are making a certain mistake, but until one knows enough to understand the smaller scales and how the astronomers of the 20th century (and earlier) figured out the distances and discovered what they discovered, I'm not going to attempt to explain it.
    15:40 I agree, based on the sheer size, there have to be many life forms, and some small fraction of them must have developed the intelligence to invent things, observe things, and figure things out.
    16:10 Our theorizing includes understanding the laws of physics, and also the observations of our telescopes.
    Here's one way to imagine the distance to Pluto and the distance to Proxima Centauri (the closest star). Think of the trip to Pluto as a two or three mile walk. The trip to Proxima Centauri would entail departing the southernmost tip of Argentina, walking north through South America, Mexico, the USA, Canada, and Alaska, traversing the strait to Russia, walking through Siberia, crossing the Himalayas (where Mt. Everest is), going to Saudi Arabia, and South through Africa down all the way to the tip of South Africa.
    Here's another thing: once it was discovered what stars were like, it was discovered that the sun is an ordinary main-sequence star.

    People sometimes talk about traveling outside the universe, but if the outside is travelling away from us faster than light, it is something we will probably never do. Our universe is essentially a bubble and we are bound within that bubble. Nonetheless, given the universes probable size, we have more than enough to explore with worrying about going elsewhere.

    11:27 A very simplistic way to put it is, if you see a Mountain far away, the light that reflects that light so your eyes can detect it is a matter of less than a Second, but it would still take you hours to drive and get to that mountain right?
    This would be the most basic simple concept how we map the known Universe. But how we do it, we measure the light, using telescopes, the hubble and now the JSW who can see farther than us, lots of math and physics and lots of experimentation and lots of very smart people like Einstein who have been working on this for many generations.

    I really think you should watch the entire Carl Sagan speech called "Pale Blue Dot." The RLL video is great, but it misses a lot of what was said in Carl Sagan's speech that, in my opinion, is more humbling. The best way to explain how they measure distance in space is by using light.The longer light travels, the more the waves stretch out. This is called "redshifting," and you can see it in both the Hubble Deep Field photo as well as the JWST Deep Field photo. But they also use other methods besides that to determine distances for both objects within our own galaxy, and other galaxies.

    What has always blown my mind is the advances in technology in such a short amount of time. It's hard to comprehend that no one thought about the concept of a combustible engine 5,000 years ago. I use 1900 as the foundation when technology rapidly advanced to where we are now. Of course, that also could be why we're still here. If nuclear weapons were developed 5,000 years ago, would we even exist today?

However, I say we humans, lesser than grains of dust deserve to worry of things that make up our very own personal universe than just dismissing it in the name of the universe.

    The part that breaks my brain is the notion of "outside". Like, what's outside of the universe? Does it go on forever and ever? Does it have a wall? What's on the other side of the wall? No matter how you look at it, the entire universe is infinite. That means that there are infinite combinations of particles and energies, and infinite copies of each. That means there are infinite copies of you reading this comment.

    • @TheKickKat
      @TheKickKat 4 หลายเดือนก่อน

      "How you look at it" does matter as there are several hypotheses that promote the existence of a finite universe. One cannot defacto claim that the universe is infinite, let alone that it contains infinite amounts of matter and energy existing in every possible combination and configuration an infinite number of times each.
      One problem with an infinite amount of everything-that-is-not-nothing, (collectively: "stuff") is how much stuff an infinite amount is. Infinite stuff requires a universe with infinite space just for it to all fit with no room to spare. That much stuff will fill every bit of available space in the entire universe until no usable space remains.
      Another problem is that if there is an infinite amount of stuff in the universe, the amount of stuff always has to be exactly infinite. The existence of more than, or less than infinite stuff is a physical and logical impossibility. This is incompatible with real world observations of particles "spontaneously popping in and out of existance", seemingly out of nowhere, and supported by further observations made and physical measurements taken from experiments conducted in controled laboratory environments.
      I cannot even guess what would happen with thermodynamics or maybe space-time and special relativity.
      It just occurred to me that you were maybe trying to describe a multiverse hypothesis. One posits that there are an infinite number of universes, similar but different than ours. Their time-lines all run in parallel but events happen independently for each universe. This means that across all of the realties, anything that could have happened has happened, and anything that can happen will happen. For example, in some other reality in a parallel universe, an alternate "me" managed to type this reply in less than 2,000 words. 😌
      If you were talking about parallel universes, you can just skip reading those paragraphs above about an infinite universe and infinite matter/energy, that you probably have already read if you have made it all of the way down here.
      So ...
      ...
      🎉 Congrats! 🎉
      You made it down here. 🥳
