    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.

    One of the latest telescopes, the James Webb Space Telescope is basically breaking some theories because we can see further and in different wavelengths better than ever.

      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 difference between us and ants are really insignificant even on our solar neighborhood level.
    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.

This cosmic inflation expended the universe from the Planck size 10~43 meters to the size of a basket ball in 10-33 of a sec, while since then the universe only reached roughly 10exp25 meters in diameters in 14 billions years… ( at least the observable part of it)

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.

    HOW WE ARE MAPPING THE UNIVERSE
    The James Web Telescope helps out a lot, but before that, Hubble helped us map the Super Cluster and beyond. In order to get detailed maps of the entire Universe a telescope has to fix its sights on a region of space for days or weeks on end. The further away a planet or star is the more Red Shifted it become in the image. With the help of Computers (Super Computers) and now A.I mapping these still images and putting them in to the puzzle is simple. This is how we know what the Universe looks like (not right down to all the planets, rocks and rogue moons / planets) but galaxies and stars that are so large or bright (even though most stars we are viewing are now dead and gone) allows us to map out the entire Universe.
    That Yellow Dot is what we can see from Earth, the surface with our eyes, not what we can see via space based telescopes. The JWT will in time be able to zoom further out than what we can currently view. It will take time and it may show us that the whole Universe as we now see it is way bigger than that or it may find that the Universe which we now view is just that, there is nothing beyond it.

    So, by using out satellite telescopes we have in orbit, they pick and track a single point of light. Then, by using whatever computer programs NASA has they can tell how far it is and plot it on a 3D map taking its distance and position is based on the Earth. They can also analyze the light composition and tell if it’s a star(and what type), if it’s a galaxy, nebula, black hole, anything really. So, as far as mapping, imagine the inside surface of a dome, that’s the sky as we see it; take the x and y coordinate of a spot of light and plot it, then using the distance(measured by analyzing the light from the object) they create the 3D maps they use in the video

    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.

    there is sure to be life out there but intelligent life could be rare. 99.9 percent of life that has ever existed on earth is extinct, add all the factors into the equation that allowed humans to evolve, mass extinctions, the moon controlling our tides, so many other events to enable this. when you take into account the short time humanity has existed and the age of our planet and the fact technology isn't even anywhere close to enable us to travel any vast distance and the behaviour of humans why do we assume that other civilisations out their have not destroyed their planets or wiped each other out as we seem destined to do. Einstein once said "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe."

    10:50 A telescope in space can only see so far with visible light. It can "see" or detect a lot further with infrared spectrum. That is how they can see and name stuff outside our galaxy.

    Very good question: how they know all this? The answer: scientists are able to do many kinds of fancy measurements and computations on the signals (light radio waves, etc) we receive from the universe where the principles of Relativity, red shift, gravitational lensing, and all kinds of other stuff etc. etc. are used to obtain information out of the light that reaches us and our telescopes. Basically: lots, and lots and lots of measurements, lots, and lots and lots of computation!

    All we know about the observable universe is done with huge arrays of telescopes and large scopes in space (Hubble, JWST). There's a huge difference between what we can see with our eyes and with those specialised telescope systems. We don't send probes out or use any sort of radar systems. As soon as you're talking about lightyears, those kinds of methods go right out the window. We observe the universe by capturing light, but the farther out the objects are the older the light we see from it is.

    @10:29: WE CAN SEE IT! that's how we know it's there. We can literally look out and see all this stuff we will never be able to touch. Like a poor kid window shopping before christmas.
    The truly odd part of this is that the universe is the universe no matter which way we look. There is no such thing as a front or back of the universe. No edge. And no center. We can look back but the idea of looking forward is nonsensical.

    How we know? The answer is actually fairly simple: telescopes. That and a whole bunch of thinking about what we're observing with them, but ultimately it comes down to telescopes. Great invention, some of Galileo's earliest observations already gave us a ton of information about our own Solar System.

    Land-based telescopes have been the major tool in discovering what exist in the universe. Much of this only came about in the early 20th century by Edwin Hubble. Before then, they though the galaxies they were viewing in their telescopes were nebula within our own galaxy. Edwin Hubble devised a method of measuring a specific type of variable star in the Andromeda galaxy. This method resulted in showing the Andromeda galaxy was actually 2.2-million light years away, and not within our galaxy. With galaxies further away, they measure the doppler effect, where an object moving away will take the visible light and shift it furth toward the red part of the spectrum. Even with an amateur telescope in a dark backyard, people can view galaxies over 100-million light years away. So, yes, we have the equipment that created this knowledge of the universe and help map it.

    we've taken endless "photos" on earth and above earth at patches in the sky that because of gravitations lensing, show us what exists beyond our own system. Best way to wrap your mind around it, is studying red and blue shifting. Light tells you not only what matter exists but what that matter is made up from.

    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.

    Also, putting things in perspective:
    It takes the earth one year to orbit the sun.
    It takes the sun about 250 million years to orbit the galaxy. For perspective the first dinosaurs were arising about 250 million years ago.
    The solar system has made about 18 cycles around the galaxy since the solar system formed 4.5 billion years ago. Well so I have read.
    The universe is vast but most of the observable universe is completely inaccessible apart from light and cosmic rays that came from it.
    The Andromeda galaxy is on a collision course with the milky way but it will take another 4.5 billion years to arrive.

    We may be small in an astronomical sense, but when you really think about it, if not for us, if not for life, the entire universe, nomatter how big, would serve no purpose what so ever. In a universe without thoughts, feelings, emotions and understanding, nothing at all, matters. Stars may explode, galaxies may collide, but without life it might aswell not happen as it has no impact on anybody.
    We may be small in a psysical sense, but we bring meaning to the universe, and even if we're not alone in this, which we most likely aren't, that still makes us rather significant if you ask me.

    To put it into perspective, there are things around us that we cant see, cant hear and cant smell. Other animals however can.
    To study the universe we use machines and computers that let us take in all sorts of information (not just light) which we couldnt gather otherwise.
