This is a simulated view of the entire observable universe. Each dot is a group of superclusters. The universe has a size of 93 billion light-years and a mass of 10 to the 53 to 10 to the 54 kilograms.
IC 1101 is a supergiant elliptical galaxy 30 to 60 times the size of the Milky Way. The number of galaxies is estimated to be between 100 billion and 2 trillion.
This animation shows the stars in the constellation Orion. There are as many as 10 to the 24 stars in the universe. 8 percent of them are Sun-like G-type stars.
The number of atoms in the universe is between 10 to the 78 and 10 to the 82. The five most abundant elements are hydrogen, helium, oxygen, carbon and neon.
The most common particle in the universe, with a number of 1.5 times 10 to the 89 is the photon. There are almost as many neutrinos as photons.

Yes, that is correct. There are 1.3 times 10 to the power of 22 planets in the habitable zone of a G-type star. 12 % of the stars are orange dwarfs (K-type, just a little bit smaller than the sun). About 73 % of the stars are red dwarfs (M-type). 20 to 40 % of red dwarfs have a planet in the habitable zone.

I think we will soon learn how earth-like these planets in the habitable zone are. HIP 11915 is an interesting system. A sun's younger sister (age 3.9 Gyrs) with a cold Jupiter at 4.8 AU. https://en.wikipedia.org/wiki/HIP_11915

ALL that and we got the only planet with trump on it.
What the fuck.

And this is just the *observable* universe - the tiny part of it that we can see/measure. We basically have no idea how much bigger it really is. Estimates range from "250 times bigger" to "infinite".

Your posts make me happy in these dark times.
This is the space not made in a Hollywood basement.

One of my favorite things about being alive in the 21st century is that we are able to just look this information up in seconds. It’s incredible that we know this, our ancestors could only imagine these boundaries, but now we know.
It’s fascinating

*autistic screeching* THE EARTH IS FLAT, MOON LANDING IS A HOAX. SPACE DOESN'T EXIST!!! /s

We can look up information in seconds, but somehow there's still MAGA, people who refuse to learn.

Now with AI suggestions to keep you engaged you can look up misinformation twice as fast

Funny nobody seems to look up history.
mrpink83
Even in our own personal histories, we tend to ignore it. :<
ahbiteme
And imagine where we'll be in another 30 years. Another 50 years. Another 100 years.
Just how far we've come over the last little while is insane. Think about the time between the first powered flight and landing on the moon, for example. Everything we see as state of the art now will feel like "They used to do THAT?" in 50 years.

I like to use "back to the future 2" as a reference. That was the future, as seen through the lens of the 80s. Now, our idea of "the future" is completely different from what it was back then.

54 kilograms ≈ 119 pounds or 8 stone, 7 pounds, 0 6/8 ounces

10 to the 54 kilograms ≈ 10 to the 119 pounds.

So like 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 pounds. Crazy how math works, huh? /s

Thanks bot. The universe is just short of 120 pounds.

Some astronomers think the CMB cold spot could be where our universe collided with another universe https://en.wikipedia.org/wiki/CMB_cold_spot .
ItHappenedInThe20thCentury
Less than 10^100 atoms in the whole observable universe. And yet we can so easily conceive - at least symbolically and operationally - numbers so much bigger than those that we open up entire new avenues of math.

The fact that this is actually not wrong makes me irrationally angry.

How the universe is larger than its age times the speed of light will always blow my mind.

Oxygen is that common? I did not know that. I'm not sure why that shocks me though.
Oktay74tn
Carbon-12, oxygen-16 and neon-20 are very common because they are the fusion product of helium-4. Helium is the second most abundant chemical element in the universe. This is why elements with an even atomic number are generally more common than those with an odd atomic number.
cousteau
If I understand correctly, C, N, O appear early on in the sequence of common nuclear reactions. I never heard of neon being involved in common nuclear reactions but I guess it'll come up at some point.

two interesting additions: over 90% of all matter in our universe is undetectable (so far) dark matter and over 90% of all detectable matter in our universe is plasma. not solid, not fluid and not gaseous, but plasma. that is because we live in a giant explosion that still happens. have a nice day, fellow stardustpeople!
frontseatdog
Maybe.

I'm working on my general knowledge of things and today I learned that a parsec is not a made-up term.
cousteau
One parsec is the distance at which a star has to be so that the Earth revolution around the Sun makes it be seen with a parallax of one arc second (hence par-sec).
Parallax is what happens when you look at an object with one eye closed, then open the eye and close the other, and the object appears to shift to a different position because you're looking at it with your other eye.
But instead of two eyes, we're looking at the object from two points of Earth's orbit around the Sun.
cousteau
One arc second is 1/60 of 1/60 of a degree.
Oktay74tn
One parsec is 3.26 light-years. The parsec has the advantage that you can work with smaller numbers.

And of all the galaxies, and of all the stars, and of all the planets, we have to get Trump.

Eh, its pretty big...I guess.
thatwoodguy
Cheer me out. If the universe is expanding, and the distant galaxies are moving faster and faster away from us more distant they are, wouldn't that mean that there's extra space being created everywhere and within all objects in the universe at the same time?
cousteau
As per my understanding, yes. That's how the Big Rip may eventually happen.
Oktay74tn
The raisinbrad model describes the expansion https://commons.wikimedia.org/wiki/File:Raisinbread.gif . The dough gets bigger but not the raisins (=galaxies). One possible scenario is the Big Rip. However, dark energy evolves over time. That makes a future Big Crunch a bit more likely. This is my clip about dark energy /gallery/dark-energy-evolution-over-time-prlkgDS .
thatwoodguy
But why would universe expanding not create any space between objects of mass or galaxies? Unless Dark Matter , or dark energy prevents this somehow?
trinxter
A little confusing. Why focus on IC 1101, and how many galaxies are in the cluster around it? WIkipedia is only minimal help: "Abell 2029 or A2029 is a large and relaxed cluster of galaxies 315 megaparsecs (1.027 billion light-years) away in the constellation Virgo.[5] A2029 is a Bautz–Morgan classification type I cluster due to its large central galaxy, IC 1101. Abell 2029 has a diameter of 5.8–8 million light-years." Still no idea how many galaxies in that cluster.
Oktay74tn
IC 1101 is just an example. I find IC 1101 interesting because it is at the upper limit of the largest galaxies.
TheBlueMuppet
I would guess that there's a minimum density for galaxies, below which it can't hold itself together, but there must be a rotation component as well. There must also be a maximum density, above which the whole thing crashes into itself. I guess the galaxies that we see are all in this sweet spot, and the extremes are too dispersed to see, or are black holes or something. (Assuming we've been around long enough for a galaxy to fail inward).
Oktay74tn
Yes, that's a great point. We exist because the relationship between the four fundamental forces in physics is the way it is. https://en.wikipedia.org/wiki/Fine-tuned_universe . There are also examples in chemistry, e.g. the beryllium barrier or the carbon-12 isotope in Hoyle state or the strength of the different chemical bonds.

More stars in the universe than grains of sand on all the Earth's beaches.

But the creator of the universe is a bloke called "God" and he hovers over this one single planet, the only one with life, watching people masturbate.

Also, more planes in the ocean than submarines in the sky
