Comments by "H. de Jong" (@h.dejong2531) on "The First Real Images Of Mercury - What We Found?" video.

  1. No, MESSENGER did not create the first "real images" of Mercury. Mariner 10's photos were no less real than MESSENGER's, they just had a lower resolution.

  2. No, this is Mercury. It should not be a surprise that they look similar: both are rocky bodies with no atmosphere and a similar composition.
    2
  3. The Apollo program enabled development of the computer you're watching Youtube on. You're welcome.
    2
  4. The photos at the start of the video are all real.
    2
  5. Ejecta falling back into the crater, mostly. This happens on Earth as well.
    2
  6. Anyone who claims Earth is flat does not have the tools to distinguish reality from nonsense.
    2
  7. It means "divide the distance by 2.5".
    2
  8. Nope. We have tons of photos of every planet.
    2
  9. 10,000 satellites in orbit prove you wrong.
    2
  10. We have millions of photos of Earth, starting with the hundreds of photos taken by the Apollo crews. These days, geostationary weather satellites take photos of an entire hemisphere every 10 minutes.
    2
  11.  @mj7335  Incorrect. The Apollo crews took photos using analog photo cameras. Weather satellites produce photos. So do Earth observation satellites. None of this is CGI, they are actual imaging data.
    2
  12. "in" the moon would be in a tunnel below the surface. We don't say "in" Earth either.
    2
  13. Images like 0:14 are real. In this case, the color yellow is used to indicate where we found water. This is called a false-color image. It is based on photographic data, using a camera that can do more than just create RGB images. Narrowband filters allow for detection of e.g. water. An image using this filter creates the yellow dots on the image.
    2
  14. We have real images of Earth going back to 1947, when a V-2 rocket was launched to an altitude of 100 km and made a photo of the landscape below, showing Earth's curvature. Since then, millions more have been made. Right now, dozens of satellites are continuously taking photos of our planet.

  15.  @RabbitholeIsrael  What you saw were photos that were manipulated to make the planet look flat. When you take photos that are not distorted, Earth's curvature is visible. Earth's curvature is confirmed by any number of methods: geodetic surveys that measure the shape of the surface directly. Observations of things like ships going over the horizon. Earth's shadow, as visible during a lunar eclipse.

  16. There IS light in a vacuum. The only thing absent in a vacuum is light *scattering*. Your claim that "no real images" exist is also false. Millions of images of objects in space exist.
    1
  17. Incorrect. The images shown at the start of the video are photos.
    1
  18. The sun does not have micronovas. That's sensationalist nonsense cooked up by people who profit from selling lies.
    1
  19. We have independent proof that "they" do send spacecraft everywhere.

  20. The images shown at the start of the video are photos.

  21. You've got that backwards. The current hypotheses for how stars and planets are formed are based on the laws of physics that we've observed, and the stages of star and planet formation we have observed. These are used to create a model for planet formation, which we can confirm or disprove by further observation. The 'plasma model' is a hypothesis we have tested through observation. It failed: our observations show that the universe does not behave as predicted by this model, which means the model is incorrect.
    1
  22. Those equations and models are the result of us gathering evidence.
    1
  23. We do what we can with the data we have. We have a lot more data about Earth than Mercury.
    1
  24. Real pictures are available now, the Planetary Data System has about 1 million MESSENGER photos. This video does a bad job of showing them off.
    1
  25. We have complete photos of Earth (showing the entire surface) going back to the 1970s, when the first Earth observation and weather satellites became operational.
    1
  26.  @param888  I'm not a video creator, but here are a few resources you can look into. Landsat is the first Earth observation program. The photos taken by these satellites are available for free. US Weather satellites are operated by NOAA, and they make the photos made by their satellites available as well. Eumetsat is the European agency for weather information, and they do the same with photos from their satellites. The Apollo crews were among the first to take photos of the whole Earth. Those photos are in the Apollo Flight Journal.

  27. Space exploration is not just about exploitation. We want to know how the universe works.
    1
  28. the first ~15 seconds of the video are real images.
    1
  29. That is incorrect. Impact craters cause a raised center when material flows back into the crater and collides in the middle. Part of the ejecta fall back into the crater, which makes them shallower. There is no evidence that supports the 'electrical discharge' hypothesis - this is part of the "electric universe", which is a crackpot idea that has long been disproven.
    1
  30. No, that's just bad reporting. Our sun will not go supernova.
    1
  31. Nope.
    1
  32. We have tons of independent confirmation on NASA discoveries.

  33.  @FlatWaterFilms  I can see satellites even with the naked eye. I can measure their speed and altitude from the ground: satellites move at 28,000 km/h, a hundred times faster than any balloon has ever been. This proves that satellites are not balloons.
    1
  34.  @FlatWaterFilms  So, no evidence to support your position then, just an empty claim.
    1
  35. Look up at the sky tonight. You can see satellites pass overhead, even with the naked eye, proving there is no firmament.

  36. Saturn's rings are easily visible from Earth. The rings on Jupiter, Uranus and Neptune are much fainter. Uranus' rings can be seen through terrestrial telescopes and were discovered in the 1970s. The Voyager spacecraft discovered Jupiter's rings in 1977. In 1984 Neptune's rings were discovered when an astronomer observed Neptune passing in front of a star, and he noticed that the star blinked several times on each side of Neptune.

  37. We have those going back to 1947, when a V-2 rocket was launched to an altitude of 100 km and made a photo of the landscape below, showing Earth's curvature. Since then, millions more have been made. Right now, dozens of satellites are continuously taking photos of our planet.

  38. Actual research shows that oblique impact still create circular craters.
    1
  39. No grift, just actual science. MESSENGER took about 1 million photos of Mercury, this video just does a bad job of showing those.
    1
  40.  @bmstockwood291  They ARE photographs. The only difference between the photo camera on MESSENGER and a consumer camera is that MESSENGER has the ability to take photos through more color filters than just RGB.
    1
  41. Because there's very little debris in space.
    1
  42.  @SubCultureVulture702  in low to medium Earth orbit, there is enough man-made debris that yes, satellites in LEO get hit regularly.  This debris was created by failed launches (upper stages exploding), insufficient passivation (decommissioned satellites exploding), degradation (paint flaking off), military action (tests of antisatellite missiles), and satellite collisions. Once you're out of Earth orbit, this type of debris no longer occurs. The average density of space in our solar system is on the order of 1 atom per cm3, and the average size of objects out there is ~ one atom.

  43. Nope. Time dilation on Mercury is tiny. one hour to an outside observer take 3599.99991 seconds on Mercury.
    1
  44.  @bloodyorphan  I don't need to fly to Mercury, I can measure its orbital speed from here. The time dilation on Mercury can then be easily calculated. And that time dilation has been confirmed by the spacecraft sent to it: if it had experienced the huge time dilation you claim, it'd have been immediately noticeable as it got closer to Mercury.
    1
  45.  @bloodyorphan  I assume you mean MOND. That hypothesis has not been proven to this day. Observations correlate only weakly with MOND, and we have found galaxies without dark matter, which MOND cannot explain at all. And MOND does not claim that Mercury has its time dilated by a factor 4 million.
    1
  46. I figured out where your '4 million' confusion comes from. You're multiplying instead of dividing. The time dilation is actually 1:40,000,000, i.e. after 40 million seconds, the time difference is one second. Which matches my "one hour to an outside observer takes 3599.99991 seconds on Mercury".
    1
  47.  @bloodyorphan  Mercury does not travel at the speed of light, so that result doesn't seem relevant to what we're talking about here.
    1
  48.  @bloodyorphan  You continue to use the wrong operator. The frequency shift when talking to a spacecraft at Mercury is 1 divided by 40,000,000, not multiplied by 4,000,000.
    1
  49.  @bloodyorphan  You continue to use multiplication when you should be using division, so the time dilation you come up with is 20 orders of magnitude too high.
    1
  50.  @bloodyorphan  Yes, general relativity is well-proven. Your claim that time on Mercury flows 4 million times faster than on Earth is NOT proven and is based on a basic mistake that I've now pointed out to you 3 times.
    1
  51.  @bloodyorphan  You keep making the same mistake! On Mercury, time flows 1/4000000 slower.
    1
  52. So, you blithely dismiss the actual science in this area, which is based on observation and experiment, then proceed to present an alternative hypothesis for which you present no evidence at all?
    1
  53. Those claims have all been disproven.
    1
  54. Because the force pulling it towards the sun is balanced by the centrifugal force caused by its orbital speed. Just like all of the planets.
    1
  55. I can look up tonight and see the ISS pass overhead, proving that space is real. We only see one side of the moon because it is tidally locked to Earth, as many moons are. Look it up. Armstrong "admitted" no such thing, the Apollo missions have been proven real.
    1
  56. That is incorrect. We have millions of photos of Earth from space. From the Gemini program onward, every manned mission took cameras along. Apollo missions made iconic photos of Earth from the moon (Earthrise, Apollo 8 and Blue Marble, Apollo 17). By the early 1970s, the first Earth observation satellites came into service (Landsat), which have been photographing Earth's surface in detail ever since. Geostationary weather satellites take photos of the entire hemisphere every 10 minutes. Just about every mission we sent to other planets carries cameras, too.

  57. The spacecraft is insulated to keep its temperature within the limits of the materials it uses, obviously.
    1
  58. It means "divide the distance by 2.5", obviously.
    1
  59.  @charlesspringer4709  Meh, multiplication and division are basically the same operation, just swapping the factor n for 1/n. Colloquially, it's clear to everyone what is meant by "2.5 times closer".
    1
  60. Photos of Mercury are shown at the start of the video.
    1
  61. False. We have lots of observations of new craters being formed (this regularly happens on the Moon, for instance). We have a physics model that shows how impact craters are formed. We track hundreds of thousands of asteroids that can impact any planetary body. Apart from volcanism, we don't have a physics model that provides any other explanation for crater formation.
    1
  62. The first photo of the far side of the moon was made by Luna 3 in 1959. Since then photos of the far side have been made by the Lunar Orbiter series, the Apollo missions, the Lunar Reconnaissance Orbiter, Chandrayaan-2 and several Chinese lunar spacecraft.
    1
  63.  @WSCLATER  MESSENGER made high-resolution photos (down to 20 meters/px) of the entire surface of Mercury, taking about 1 million photos to do so. This video does a bad job of showing off all that data.
    1
  64. False. We can see just fine out there.
    1
  65. MESSENGER took more than 1 million photos in total, so at least 200k of Mercury.
    1
  66. Nope We have a spacecraft orbiting Mercury, carrying a camera.
    1
  67.  @EdjeBos  The Planetary Data system is a public archive that holds the raw data from all spacecraft that have visited other planets, including MESSENGER's photos of Mercury.
