@@ViperDivinity The earth's deep sea is denser than you think, it gets dark every time you go deeper in water. It’s also like being in space but in water, you can’t even see, It’s like being inside a huge fog. So it’s hard for scientists to explore and find new sea creatures. 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.

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.

@dangeros31 2 роки тому
@@shozinryu4 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.

In 185 AD, Chinese astronomers recorded the appearance of a bright star in the sky, and observed that it took about eight months to fade from the sky. It was observed to sparkle like a star and did not move across the heavens like a comet.

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 Bible tells us it is around 6,000 years of course. Around 2,000 years from Adam and Eve until Noah and the flood, then about 2,000 years from that until Jesus Christ died on the cross for our sins, and about 2,000 years from that until now. 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.

Great vid! If the universe is indeed on the surface of a torus (donut), could that donut be expanding differently in different directions? That is, can the radius of the ring of the donut be expanding faster/slower than the radius from the center of the donut. And, if so, perhaps the hubble constant is a function of two different expansion rates, where the actual value is based on the direction. Just a thought ...
@tylerdurden3722 2 роки тому
The universe isn't really expanding in that way. There are two ways things can become further apart. 1. Is the common way of simply moving the two objects further apart, moving the objects through spacetime so that there is more spacetime between them. 2. Is to increase the amount of spacetime between the two objects, without moving the objects. E.g. Putting more spacetime in between them. The universe is expanding in way number 2. There is constantly new spacetime appearing in between galaxies (no one knows why this is happening). Which makes galaxies become further apart (without actually moving, in any significantly way). This "expanding" happens everywhere, except inside and around galaxies (no one knows why). In other words, the universe isn't expanding inside galaxies...only outside galaxies. The shape of the universe is unknown, but when refering to things like shape, words like "shape" doesnt have the normal meaning as in normal vocabulary. It has more to do with whether the universe is infinite or not (which is unknown). It's almost like the word "theory". In normal vocabulary, "theory" means hypothesis. In physics, that word has a different meaning. The same with "Law", "Spin", "strange", etc. Common words from the common vocabulary are used in Physics for unrelated concepts. The "shape of of the universe" doesnt refer to the common vocubulary's meaning of the word "shape".
@JH-en6ql 2 роки тому
@@tylerdurden3722 thanks for your response. I understand the universe is expanding as you described in #2. See journal article by Buchert re 3-Torus universe topology. I believe they said that the 3-torus (I’ll call it donut from now on) has grown from being infinitely small to around 4 times or so (can’t remember the exact number without looking it up) larger than our observable universe. Now assuming the topology of our universe is indeed a donut, there are two parameters with respect to size of that donut. The first is the radius of the hole, call it R1, and the second is the radius of the donut if you were to slice into one side from the top down. Call that radius R2. Now, what I suggested above is that R1 and R2 can be growing at different speeds, which would in theory cause the Hubble constant to differ based on direction in our 3D space on the surface of the donut.
