I was pretty surprised the first time I encountered a St. Bernard. I was working at a fast-food drive through window and his head seemed to fill it top to bottom and side to side!
The one that made me go, “huh?” Was the wild boar skull. The previous pic of wolves and coyotes made wolfs seem massive. So just how big are wild boars?
That absolutely blows my mind! NASA used the term “explored” rather loosely.
Video of an eagle carrying a goat (not for the squeamish):
Start at the 5:00 mark.

We had a Saint when I was a kid. 200 pounds of slobbery love. 
Not in a position to watch the video right now, but when I saw the title of the thread, what came to mind is the Saturn V rocket. When I walked into the building housing it at the Kennedy Space Center, I was blown away by how large it was. It’s one thing to know something is big; it’s another to actually see how big something is! And all that so it could accelerate a tiny portion at the top to the moon.
It’s unfortunate that there is no effective treatment for macropsia; however, don’t give up hope because it could happen in your lifetime.
And cricket grounds are even bigger. The MCG in Melbourne has a diameter of 180-200 metres. It is massive.
Agreed, it is almost sarcastically big. You can barely take it all in in one sitting. Just a single engine nozzle on S1 is stupidly big, then you realise there’s 5 of them, then you realise that you’ve barely started to look at the thing.
It is a wonderful thing to see in the flesh.
I was out on a surveying job here in Wyoming and came across a very large, dead Golden Eagle. Its talon could have easily wrapped around my upper arm :eek:
I routinely drive in the active coal mines here as well, and it is… humbling being next to some of the equipment on site. Here is one of those haul trucks with a person or two next to it for scale… I also recently did some work near one of the actively operating draglines at the coal mine… watching it work, it just looks slow and ponderous, merely due to scale. But while it it turning, the far end of the boom is moving in excess of 120 MPH :eek:
Why is that surprising? Getting a covered warehouse for filming it was expensive. There was already such an expense getting Kubrick on board that there wasn’t much left over for sets. 
The Big Muskie I mentioned upthread was a dragline. Simply enormous.
Whereas the diamond and base paths are…just exactly the same size as the field my slow-pitch softball league played on. I once got to run the bases at Turner Field, and was bemused by that fact. Intellectually, I knew the dimensions were the same, but it just felt like a major-league diamond should be bigger than a beer league field.
I third the idea of the leviathanical size of the Saturn V. Nothing is so uncomprehensibly large, especially with the (relatively) low ceilings it’s just impossible to get it all in one shot.
See just how large traffic lights are has made a little more nervous about driving under them. If one of them goes crashing through my windshield I’ll be dead for sure.
This. Seeing the Eiffel Tower in person, you realize that it’s taller than most skyscrapers.
I hear ya, but by design they weren’t meant to be outside the LEM very long (~2.5 hrs I recall) nor to stroll very far from it in case of any emergency. Once the astronauts and equipment were evaluated following their return, later missions were OK’d to increase distance and time outside the LEM.
I also understand your point, but upon reflection I think the term “explored” greatly under-describes the achievement of Apollo 11.
Every bit as impressive is their strength.
I’ve been out hunting with falconers that had 2 golden eagles, and got the chance to hold one on my arm (for just a couple of minutes - they are heavy birds). Their grip strength - which they need to drive the talons into prey - is frightening. If they had comparable strength to twist their legs, it feels like they could easily break your arm. Fortunately, they don’t - not needed to secure a meal of jackrabbit.
I’m pretty sure that was a life-size plastic model
Sort of like Spaceball One.
That crocodile is about the same size as the one that ate Captain Hook.
In August, 1972, I flew to Athens, Greece, to catch up to USS John F Kennedy (CVA-67). The ship I went to was CA-12 USS Columbus, riding anchor off Piraeus, just to wait for Big John to get there. Now, Columbus was a large ship, much larger than USS Amberjack (SS-522), my first ship. JFK anchored, and we of the transporting crew mustered and jumped onto 72-foot motor whaleboats to transit there.
Now, Kennedy looked large from a couple of miles away. As the boat approached, she started looking larger, and then impossibly larger. As we approached the after companion-way, Kennedy just looked immense. From the gunwale of a 72-MWB you’re about 6 feet off the water. The flight deck is something like 80 feet overhead, and there’s about 60 feet of fantail on each end of the MWB. That was a big day.
I lived through it.
On a trip to Germany, I went to see the cathedral in Ulm, one of the tallest churches in the world. For a couple euros, you can climb almost to the top. It’s a long climb, almost as tall as the Washington Monument. The topmost part, where the walls start sloping in to form a point, is all open like a lattice. Some of the Gothic motifs that look small and spindly from the ground are as big around as my waist.
