  1. I wouldn’t say ๐˜ญ๐˜ช๐˜ฌ๐˜ฆ๐˜ญ๐˜บ that the first stars are in 13 billion old galaxies, no. According to current theory, the first stars were likely mostly gigantic (which die in millions or even thousands of years), given that the Eddington’s limit depends on the metallicity of the stars, which was likely 0 for most of them and just a tick more than zero for those who were unlucky enough to attract the ridiculously tiny amount of lithium that was created in the big bang nucleosynthesis. Like, the amount of gas that it took for a gas cloud to “break apart” because a protostar could not “hold it” that big was a lot biggerโ€”leading to a bigger star. On the other hand, many smaller stars may have been created from a smaller cloud that was between two proto stars that couldn’t hold that smaller amount of gas. So I’m not saying that weren’t any third generation smaller stars, only that they likely didn’t make up a big enough part of the sample that a small subset of galaxies is “likely” to have had them. Especially in a time when most of the mass was not in galaxies.
    If there had been the proportion of smaller stars that we expect to be created with the current Eddington’s limit, we would probably have more black holes in the galaxy bulge than we’ve been able to.

    One other thing is that the light we’re most likely to see is that from the most luminous stars, so they were probably OB type stars, which mean they couldn’t have lasted the 4+ hundreds of millions of years necessary for that. On the other hand, that doesn’t take from your argument that the “๐˜ง๐˜ช๐˜ณ๐˜ด๐˜ต ๐˜ด๐˜ต๐˜ข๐˜ณ๐˜ด ๐˜ฆ๐˜ท๐˜ฆ๐˜ณ ๐˜ง๐˜ฐ๐˜ณ๐˜ฎ๐˜ฆ๐˜ฅ ๐˜ข๐˜ณ๐˜ฆ ๐˜ช๐˜ฏ ๐˜ด๐˜ฐ๐˜ฎ๐˜ฆ ๐˜ฐf ๐˜ต๐˜ฉ๐˜ฆ๐˜ด๐˜ฆ ๐˜จ๐˜ข๐˜ญ๐˜ข๐˜น๐˜ช๐˜ฆ๐˜ด”, they just aren’t the stars we’re seeing.

  2. So much images and still cannot see Sirius A star. When you will stop hiding from us?

    If I hear big bang one more time. I’d bet my left and right testicle that we will be dating stars and galaxies prior to this theory. Back to the drawing board.

  4. So whatโ€™s the black circle in the large orange star at the top of the nebula picture. Itโ€™s on the right side on one of the light spires but it doesnโ€™t repeat on any other light refraction or whatever it is. It looks like a black star or something. I just thought it was interesting.

  5. I’ve been eligible for the Nobel Prize in Physics for 27 years. At least I discovered extraterrestrials. Through 27 years of secrecy, criminals have done immeasurable damage to our civilization and personally stole 27 years of world fame from me. JZ 17.1.95
    Ich habe seit 27 Jahren Anspruch auf den Nobelpreis fรผr Physik. Immerhin habe ich AuรŸerirdische entdeckt. In 27 Jahren Geheimhaltung haben Kriminelle unserer Zivilisation unermesslichen Schaden zugefรผgt und mir persรถnlich 27 Jahre Weltruhm gestohlen. JZ 17.1.95

  6. EPIC

  7. Thanks you vindicated what I though was in the photo was gravitational lensing

  8. Hey fraser I know almost nothing of how space works but I’m interested here’s a question, so if space is expanding and ya meantiond parts of space receding away from us so does that mean we’re see light from something moving away and I’ve heard it meantiond we’re seeing into the past it’s pretty cool huh
    But my question is if the light source was staying still or moving towards us would we have seen it sooner and how would that effect the idea or fact we’re seeing into the past?

  9. Pure science fiction.
