I read an incredible book a long time ago that gave me a sense of a) proportion and b) how and when certain things were worked out. Granted it was published in 1966 and I read it in approx the 80's, but it is still accurate with what was worked out when. It's incredible to think the Ancient Greeks worked out the diameter of the Earth (8000 miles) and then, later, the distance of the moon (240,000 miles) sheerly by practical experiments, maths and observation! It's called 'The Universe - From Flat Earth to Quasar' by Isaac Asimov. An eye-opener. Thanks for your reaction!

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.

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."

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. (And remember, at the 17 minute mark, EVERYTHING you see in the picture is a separate galaxy.)

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.

Things like this are mind-blowing. If you have about 45 minutes, there is a KZbin video called "Riding Light - Traversing the Solar System at the Speed of Light". The video is as if you are a light particle leaving the surface of the Sun. It takes you out to just past Jupiter and shows just how long it takes light from the Sun to pass different planets and other solar system objects. It really illustrates just how huge our own solar system is much less anything beyond it in interstellar space.

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.

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.

[@almostfm]

I've been to Meteor Crater. It's one of the few things in this world that's actually as big as you think it will be. Not sure if this helps visualizing the size of things, but the spacecraft that's furthest is Voyager 1 launched in 1977. By most measures, it has left the Solar System and is in interstellar space. It's about 22 light hours from Earth, compared to the observable Universe's diameter of 93,000,000,000 light _years._ When you said we're an insignificant part of the Universe, you weren't lying.

[@seantlewis376]

Two things to check out after this to blow your mind are "The Galaxy" from Monty Python and the Meaning Life, and "Powers of 10", an old conceptual video that will blow you away.

[@Jeff_Lichtman]

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.

[@Irish381]

You can barely grasp what was being shown. The magnitude of the cosmos is mind blowing. Really puts us in perspective how tiny we are compared to everything else.

[@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!

The observable universe picture is the baby picture from when the universe was only about 380,000 years old and there are no planets or stars. 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.

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...

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.

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

I've looked at stuff like this before, I've never gotten the feeling that we don't matter, though. All that empty space and lifeless areas, I tend to think we matter more than all that and people certainly matter to each other. I'm content with that

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.

There was a great website that used to show how far out our radio signals have traveled. It makes you feel insignificant as well

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