The Universe is Way Bigger Than You Think 3D - Harry Evett | Irish Girl Reacts

Check out the AMAZING featured video on Harry Evett's Channel at: • Universe Size Comparis...
Also check out Savk's original scores on his channel at / @savfkmusic
I don't think the human mind has the capacity to visualise the size of the universe which is Way Bigger Than You Think. This put it in context however and was very interesting to analyse and react to. Harry Evett's 3D graphics combined with a sick score from Savk blew my mind!!
The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe. According to this theory, space and time emerged together 13.787±0.020 billion years ago, and the universe has been expanding ever since the Big Bang. While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.
Some of the earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System. In developing the law of universal gravitation, Isaac Newton built upon Copernicus's work as well as Johannes Kepler's laws of planetary motion and observations by Tycho Brahe.
Further observational improvements led to the realization that the Sun is one of a few hundred billion stars in the Milky Way, which is one of a few hundred billion galaxies in the universe. Many of the stars in a galaxy have planets. At the largest scale, galaxies are distributed uniformly and the same in all directions, meaning that the universe has neither an edge nor a center. At smaller scales, galaxies are distributed in clusters and superclusters which form immense filaments and voids in space, creating a vast foam-like structure.Discoveries in the early 20th century have suggested that the universe had a beginning and that space has been expanding since then at an increasing rate.[16]
According to the Big Bang theory, the energy and matter initially present have become less dense as the universe expanded. After an initial accelerated expansion called the inflationary epoch at around 10−32 seconds, and the separation of the four known fundamental forces, the universe gradually cooled and continued to expand, allowing the first subatomic particles and simple atoms to form. Dark matter gradually gathered, forming a foam-like structure of filaments and voids under the influence of gravity. Giant clouds of hydrogen and helium were gradually drawn to the places where dark matter was most dense, forming the first galaxies, stars, and everything else seen today.
From studying the movement of galaxies, it has been discovered that the universe contains much more matter than is accounted for by visible objects; stars, galaxies, nebulas and interstellar gas. This unseen matter is known as dark matter.
There are many competing hypotheses about the ultimate fate of the universe and about what, if anything, preceded the Big Bang, while other physicists and philosophers refuse to speculate, doubting that information about prior states will ever be accessible. Some physicists have suggested various multiverse hypotheses, in which our universe might be one among many universes that likewise exist

The Planck Length (named after Max Planck) is basically the smallest length at which General Relativity, i.e. our understanding of the universe works. The Schwarzschild radius (named after Karl Schwarzschild) is the smallest space you can cram a given amount of matter into before its gravity causes it to collapse into a black hole. A Buckyball is 60 carbon atoms arranged into a hollow ball. The name comes from Buckminster Fuller - inventor of the geodesic dome.

Fun facts: The exact location of the tree Hyperion is kept a secret to keep visitors from damaging it. The oldest, tallest, widest and most massive trees on Earth are all found in California, and many of their exactly locations are either kept secret or are located in parts of the forests/parks that are off limits to visitors for the same reason. Also the "forest" called Pando is a clonal tree system (lots of trees that share a single root system) in central Utah that is both the heaviest organism on Earth (6,000,000 kg) and among the oldest (estimates put it between 12,000 and 16,000 years old). Another fun fact: The Planck length, coined by German physicist Max Planck (one of the pioneers of quantum physics) is considered to be the smallest meaningful measurement in physics. To put its size in perspective, a Planck length is to the diameter of a human hair, what the diameter of a human hair is to the observable universe. That is to say, you could fit as many Planck lengths in the width of a human hair as you could fit human hairs in the width of the universe. Another fun observation is the Planck temperature (roughly 1.42x10^32 in C). I won't into the specifics (not that I'm familiar with it to some PhD-level degree, it'd just be wordy), but suffice to say we literally have no idea what would even happen if something got that hot, or how physics would behave. Great video, as always!

These videos always remind me of the Total Perspective Vortex from the Hitchhiker's Guide to the Galaxy stories. In the story, the man who invented the vortex did it to annoy his wife, who would often nag him for daydreaming, and tell him to "have some sense of proportion!" And so he created the Total Perspective Vortex to truly show her a sense of proportion: "Into one end he plugged the whole of reality as extrapolated from a piece of fairy cake, and into the other end he plugged his wife: so that when he turned it on she haw in one instant the whole infinity of creation and herself in relation to it. To Trin Tragula’s horror, the shock completely annihilated her brain; but to his satisfaction he realized that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it cannot have is a sense of proportion."

[@OnlyScienceRules]

For anyone who genuinely cares (Assuming there is one): In Ancient Greece, Anaximander suggested “apeiron” referring to how big the universe must be. The Greek word “apeiron” means without limit in time and space, suggesting the universe is boundless. In other words, infinite. This makes perfect sense to me. Since things exist, there must be no limit to existence and existence must be limitless. So I think there’s that the so called “big bang” was the “beginning” of “everything”. Meanwhile, evolutionarily, the odds of us being here, not to mention being here as humans, is unbelievably small, yet here we are. That renders us individually and collectively responsible for consciously choosing to always educating and informing ourselves and each other scientifically and to abandon our archaic, outdated, untrue, primitive superstitions and fairytales and fearmongering. You only fear something if you don’t understand it or don’t know about it. When barrier is crossed, new possibilities open that you likely haven’t even imagined before. Only a few centuries ago we didn’t even know kat if what we know about the universe today. Going back to Ancient Greece which no longer exists, all those great philosophers didn’t know anywhere near what the average person knows today thanks to the enlightenment reformations and the industrial as well as technological revolutions, breakthroughs and discoveries. Back to cosmos, I still think the universe has no beginning or end, and is ultimately exempt from time. So there was never a creation. Only evolution. And we as an ape species are but one amongst possibly countless others that are intelligent enough to compose and comprise entire civilisations, regardless of their levels and scales. And there’s no way any species is the so called “center of the universe”. So don’t be self absorbent! Check out my profile entry!

If they're reasonably close (in galactic terms) they may well already know we're here. They could possibly detect artificial lights on the night side, and they could do what the JWST has already done with a couple of exoplanets-determine the composition of the atmosphere. If they saw the relatively high concentration of Oxygen, that would raise eyebrows (or whatever the alien equivalent is). Molecular oxygen will react with almost everything, so it would come down to two things: Really exotic non-organic chemistry, or life forms constantly pumping out oxygen that went out of the atmosphere reacting with iron, copper, or other stuff.

(Unfortunately KZbin has to be their money grubbing selves and wedge some ads in there. But you can download the video off of iTunes. It cost me $1.49 in the US, and I doubt it's much more in Ireland; it's WELL worth it.) It really takes off about about the 11:27 mark, and just after 15 minutes, you may feel like you've been blown out the back of the room. Oh, and if you're in a house (or have VERY understanding neighbors), I recommend you watch on the biggest monitor possible and turn it up LOUD.

I remember when I had my mind blown by an astrophysics class at University of Houston years ago. That was when they thought there were only 100 million stars in the galaxy and maybe a hundred million galaxies, now they believe it to be in the billions for both numbers; this basically makes it mathematically impossible for us to be alone in this universe. This humbling realization means Earth is not even a grain of sand on the cosmic Beach, it is more like our galaxy which is the grain of sand.

There is an episode of How the universe works that talks about the end/edge of things like our solar system, our galaxy, etc. When it comes to the universe. We can only see as far as the speed of light will let us. Every time you look into the sky you are looking into history as far back as billions of years and that is how they got baby pictures of the universe. At one point in time the Universe expanded quicker that the speed of light. That's not quite an accurate way of explaining it but close enough.

I believe the Empire State Building was the tallest in the world when it was built. It was surpassed a long time ago. Max Planck was a physicist who, among other things, figured out the smallest length that can possibly be measured (I'm oversimplifying, but I don't want to write an essay here). That distance is now called the Planck length. There are a bunch of other units named after him, including the Planck time, which is how long it takes light in a vacuum to travel one Planck length. The Planck units are interesting because they're based on the physical properties of the universe, instead of some arbitrary measure (like the meter or the second). For most purposes, though, the Planck units are at a scale that's not useful for most things. Mostly they're too small, although some Planck units are too big. A bucky ball is a molecule of carbon atoms that are arranged like the intersection points in a geodesic dome. It's named for Buckminster Fuller, who invented the geodesic dome. Soot has bucky balls in it. A bacteriophage is a type of virus that infects bacteria. The ending "-phage" means "eat," so a bacteriophage is a bacteria eater. The Hyperion redwood (the world's tallest tree) is in California, which also has the world's most massive tree (the General Sherman giant sequoia), and the world's oldest tree (the Methuselah bristlecone pine, which is over 4850 years old).

[@michaelsommers2356]

The Empire State Building was the tallest building in the world for almost forty years, until the World Trade Center was built in 1970. The Planck length is just a length that you get if you combine the fundamental constants of nature in such a way that you get a length. It is not necessarily the smallest length possible. The vertices of a buckyball are the same as the vertices of a soccer ball, not a geodesic dome.

[@almostfm]

I haven't been to the Hyperion redwood. I got to see the area where the Methusela tree is (the exact location is not divulged to the general public). The General Sherman is easy (which it hasn't snowed). It's about an hour and a half northeast of me and it is huge in a way that makes you say that no tree can actually be that big. At its base, the diameter is about 11m or 36 feet. It's at the point that you can't really understand how big it is unless you back away from it some. Otherwise, it's like trying to judge the size of a house by looking at the wall in one room.

Another thing that's helped me grasp the sheer size of the universe is the implications of light-distances. Latter 20th century science fiction films and shows tended to treat light speed as super duper fast, the way to move between star systems. (Yes I know Star Wars technically uses "hyperspace", but the early movies called it "light speed" in the dialog, so that's how audiences would think of it.) But in reality, light speed, the Cosmic Speed Limit, the fastest it's physically possible to traverse through space, is still depressingly slow next to the scale of space. The Sun is 8 light minutes away; a magical light speed space ship would take 8 minutes to reach it. The nearest star would take about 4 years to reach. The light from the Andromeda Galaxy we can see left the galaxy while non-avian dinosaurs were still around.

[@Gungazoid]

As has been said before, there are two possibilities; either we are alone, or we are not. Both are equally terrifying! I think it highly unlikely that any intelligence capable of traversing the stars will find anything here that is unique other than the life itself. Since our biology is very likely incompatible with theirs (an assumption, to be sure) we would be of no value for food, organs or anything else that requires compatibility. Bottom line, we have nothing anyone would want that they couldn't get closer to home with far less effort, so the conquest scenario is probably more projection of human characteristics than reality...

My suggestion is that: 1. the singularity before the Big Bang was all photons, and 2. that the universe was made by pair conversion where photons make electron positron pairs. Readers challenge me with, how can you prove that? Most of it has already been proved! These 3 things that we know are true, support many of my ideas on the importance of photons in physics 1. Photons are outside of time and distance. 2. Photons create an electron positron pair in pair conversion. ( During extreme conditions photons can create proton, anti proton pairs; and neutron, anti neutron pairs). 3. Should all the mass be converted to energy, we would have a universe of photons.

Buckyballs are molecules of buckminsterfullerene, which has sixty carbon atoms arranged as shown in the video. Their arrangement is the same as that of the vertices of a soccer ball. The chemical was named for R. Buckminster Fuller, known for popularizing the geodesic dome, and other stuff.

The size of the universe is incredible I just can't get my head around it.🤯😵‍💫🌌🪐🌞

You caught me in the middle of a smaller scale video that documents the construction of the Alaskan Highway by the US Army Corps of Engineers from the US through Canada to Fairbanks, Alaska which though only 1,500 miles long (approximately 2,400 kilometers) was still an amazing engineering feat.

What's interesting is after the observable universe it kept zooming out into the void further with no description meaning the possibility could be endless of how far reality can extend.

We’re nothing but ants crawling on a speck of dirt floating through endless night 😂😂

The scale of the universe is the definition of awesome

Fun fact: a person is closer in size to the observable universe than to the Planck length, and the middle between them is a human egg.

13:42 Editor Diane is really a closet optimist, who hides behind sarcasm.

"So, basically, you are inconsequential." Yep...pretty much sums up the whole aspect of life as a whole...except for those who deep down believe that the universe revolves around them.

You look at all this, all these insanely massive distances and volumes.... Yes, they're obscenely large. But they are literally 0% of infinity. All of the things in this video have an end. Infinity is the most terrifying, mystifying, and beautiful concept I think humanity has ever conjured. I would love it if you made a video reacting to Numberphile (or anyone else who does a good job of it, like the "Wait But Why" blog's article on numbers above a million) explaining Graham's number. If you ever want to have an existential crisis and start to understand how thoroughly, bone-chillingly horrifying infinity is, have a look into that.

[@TransoceanicOutreach]

Infinity only exists in mathematics, not in reality. Nothing is infinite.

To quote Douglas Adams. Space is big, I mean really big. really big. Space is so vastly, hugely, mind-bogglingly big that the majority of it simply cannot fit into the human imagination.

When it takes 100,000 light years just to cross the milky way galaxy and there are billions of galaxies its hard to comprehend the vastness of the universe

The Crab Pulsar is a remnant of a star that went supernova almost 1000 years ago. Despite being only 20 km in diameter, it has more mass than the Sun.

[@chicken2jail545]

Fun Fact: Yesterday I had a trivia question that was covered by this video, so I got it right! Yay Universe!

[@wabash9000]

Kind of reminds me of those posts "Americans will use any unit of measurement to avoid using the metric system." Sometimes showing relative size compared to known objects is very useful.

[@thomastimlin1724]

Tell Diane the Editor I still say the Walmart Main Warehouse is bigger than all this sh*t. HAHAHAHAHA

[@setokaiba6758]

I actually had a theory that light has a finite (limited) distance that it can travel, and if that's the case, with current technology we will not be able to study beyond the limits of the observable universe.

People not understanding the distances involved, is part of the reason ufo myths are so common.

Editor Diane definitely looked optimistic

really loved this video,

I’m glad!

What have always struck my mind is that if we shifted The Sun with Beetlejuice, then Earth's orbit would be within Beetlejuice and Beetlejuice is still just a star like The Sun is.

[@joe3eagles]

Not gonna comment on your hair... okay, gonna comment on your hair... It was artistic genius on your part when after watching our existence becoming so tiny as the universe became so huge that you let your hair explode out to the orbit of Neptune. Such a beautiful orbit. 😉🤣

[@TMAC_burninator]

Editor Diane: "Did we switch?" LOL

[@MagsonDare]

The "Real Life Lore" channel has a similarly named video that you might also enjoy reacting to, it's just called "How the Universe is Way Bigger Than You Think" instead ;-)
