    This blows my mind. I've always understood the concept of how objects in the sky are so far away that it takes a long time for the light to reach Earth, as if we're looking into the past. But I never considered the fact that objects between us and what we're observing could distort our observation. Science never ceases to amaze me.

      The crazy thing is that it reaches us at all, as if those objects are transparent. It's literally seeing around objects, crazy. Space is so strange. In "micro" scale it appears to be affected by mass. How can something stretch so violently while mass holds it's ground.

      I'm not saying Science is reality. I'm saying that reality is what already exists regardless of our perception; it is constant. Science is used to figure out reality, but even then Science can and is wrong, because, like you said it is always changing. Take for example the big bang. People take it as fact, but it is still just a theory that can not be completely proven. The smallest amount of evidence of scientists and people's ideal perspective of the world and universe can lead people in the wrong direction, thus making up their own false and ideal science that helps them cope with their lack of evidence. Science is just a tool to measure and observe, while reality is fact and constant; weather it can be correctly observed is another thing.

      Edit: My comment was confusing. So basically Earth’s deep sea is much more like space but it has an end and it is much more dense. once you enter a zone where no light would no longer could reach; you could experience very much pressure. And the thickness of fog made it so hard to see; it could be hard for scientists to search for creatures.

      They are actually very, very close together in the sky. The light is deflected by a tiny angle, and you would not be able to distinguish it from single source by eye even if it was bright enough to be visible. Hubble, however, has an absolutely incredible zoom, allowing it to take a region of space that would look to you like a single point in the sky and expand it out to show all the galaxies and clusters of galaxies that are there.

      The gravity slows down the light. The light went in all directions, there were 4 lenses that redirected light back to us. We knew there were 4 lenses because the galaxy appeared in 4 different places. We saw the supernova in one of those places, ie from one of those lenses, then another, so we figured it's gonna appear the other place. somehow we figured out how long the delay was (maybe looking at how out-of-phase the rotation of the galaxy was in each image) and we added that to the supernova we saw to figure when we'll see it in the last image.

      The Bible tells us it is around 6,000 years of course.

And if you think that is just a story, then why do you think the whole world uses the time frame of B.C and A.D? The Bible lists the genealogy from Adam and Eve all the way to Jesus Christ, so you can technically add all of that time up plus the year it is now and it will be around 6,000 years. Oh and also the Bible states that the earth is round.

    Thank you for the wonderful video again, Derek! I came back to it a second time, and noticed at the end you say you used to think of universe like it would be glass, and how strange it was. How do you view the universe now afterwards? I'd still think of it roughly a glass-like substance in the sense, that light travels slower through denser materials, or takes more time to traverse a thicker part of the glass. Just that in the case of the universe, that thickness is tremendous really. Curious thought I think. Here's to hoping there are other similar events coming up!
