SuperForester Lyndsey Presents: Think Big!

(image via nasa.gov)

I realized something super terrific in the past…Recent.

A lot of people I know often feel insignificant or generally “small” in terms of their confidence or worth.

When I was in 11th grade, I had this physics teacher. Mr. Vore. He was a great teacher, and he literally taught his class how the universe worked. One day, we got into this tangent about how vast outer space was.

I admit, I always knew it was, y’know, BIG. Sure it was, it’s space. But I had no idea the magnitude of it and I STILL don’t. It’s unfathomable. It’s impossible to understand. It is way too much for the brain to really comprehend in full.

I mean, the basic idea is this: It takes you 6 hours to get from Las Vegas to San Diego. That’s one fourth of an entire day. And the states are NEIGHBORS. Now imagine driving, strictly driving, all the way to the other side of the earth. Okay, so Las Vegas to…We’ll say somewhere in Russia. That’s about 5000 miles, give or take. If you’re driving at 50 miles an hour the whole way, that is 100 hours. About four days.

From here to the moon? About 238,857 miles. Driving that would take you 200 days. That’s almost a year, from here to the moon! And you can SEE the moon from where you’re standing, it’s right there! It’s relatively near to us.

The closest galaxy to us, if you count even the tiny ones, would be Canis Major Dwarf. That’s 25,000 light years away from us.

That is over a trillion miles. To be precise, about 146,962,495,000,000,000,000-ish miles.

I am not calculating driving distance for that. I’ll let you wrap your head around it.

Now if you want to talk about distance in terms of “real” galaxies, like ours, then we’ll talk Andromeda.

Bear with me. I know you didn’t sign up for a physics or math lesson, but this’ll get awesome, I promise.

From here to Andromeda is, get this, 2,560,000 LIGHT YEARS away. Which is…

15,048,959,500,000,000,000 miles. Okay. I’ll calculate that one.

That’s 12,540,799,600,000,000 days. Which is over a million years.

And, keep in mind, this is the CLOSEST ONE to us.

The closest galaxy. Out of God knows how many. What about the 4th closest? How long would that take?

Imagine WALKING that!

So with all things considered, nobody in the entire world knows how long it would take for somebody to touch the edge of the universe; especially considering it’s expanding still. It’s Brobdignagianly huge and it’s still continuing to grow. That is like, infinity years, pretty much.

So here’s the thing.

Now that you have an idea, or maybe don’t, of how gigantic the universe is, I want you all to consider this.

You’re a part of that. You feel me? You are a part of that which is unfathomably brilliant, beautiful, complex, and unbelievable. You ARE the universe. You don’t live in some little area completely separate from the universe, you don’t watch the universe scroll by you as you exist, no, you ARE that very thing which is the great big everything.

However many years ago, in one very specific spot in the incomparably ginorfous universe, there was a group of millions of microscopic cells. All of them happily swimming with their little white tails. Suddenly, they saw something big and looking comfortable. They all started swimming, all millions of them, towards this magical thing. And out of all of them, YOU were the one who managed to get yourself in there. YOU.

And this million-man race occurred in a place that occurred in a city that occurred in a state or country in a continent in a planet in a galaxy among infinite other galaxies.

Can…Can you even really put that in your head? Personally, mine hurts from it, but it’s a very endearing hurt.

So that occurrence of conception that gave you the ability to live happened in this comparatively microscopic spot in the universe. Now, don’t take that to mean you’re insignificant compared to the rest of outer space, because remember what I said: That is you. You’re not tiny compared to the universe because you are the universe.

The universe is within you and outside of you. You don’t live outside of it, you live IN it, it’s a PART of you. The light from the sun is a part of your life. That light came from a bunch of elements from the universe coming from the edges of the edges of infinite abyss and colliding together. That light is what gave the plants on Earth the power to grow, and then a bunch of animals ate those plants and evolved into your ancestors, which ate more of the plants and other animals that ate the plants, and eventually they had your parents which ate the green light-eaters, and that all led to the production of the microscopic spermy wormy and the eggy weggy… that led to YOU. See what I mean?

You are a PART of INFINITY.

-Ahem.- That having been said, how does it feel knowing that you, Mr. and Mrs. AwesomeSauce, are part of something that nobody can comprehend? You’re part of something that even the great and beautiful human mind isn’t fully capable of understanding? Not even a part of; that you ARE the universe?

Boy, I wish I could put it into words better than how I did, but it’s really difficult to understand, let alone write about. Sorry about that! I hope it at least somewhat got through to you.

Try feeling small now, folks. In reality, nothing is bigger and more incredible than you.

Love!

NASA Pic of the Day: A Chameleon Sky

A Chameleon Sky

The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star’s life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the ‘hourglass.’ The unprecedented sharpness of Hubble’s images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.”

Perseid Meteor Shower Peaks Tonight!

Heyo, SuperForest!

Tonight, our planet is making it’s once-a-year voyage through dust trailing along the orbit of periodic comet “Swift Turtle”, thus presenting us with the Perseid Meteor Shower, one of the most spectacular celestial shows (weather permitting) of the year!

According to NASA:

The Perseids shower will begin around 10 p.m. YOUR local time. However, the best times to view are after midnight and before dawn, with the best activity around 3 a.m. to 4 a.m. local time. Best conditions are a clear, dark sky away from city lights. Go outside and look straight up at the sky.

Embarrassingly, despite the fact that I’ve always wanted experience stargazing, I’ve never actually gone out to give it a shot. But it seems like tonight would be an excellent time to start.

Based off of all the articles I’ve read, it’s more visible to those in the Northern Hemisphere, so if you’re in the (very general) area, prepare some blankets and warm tea (and a laptop if you want to participate in a NASA live chat with astronomer Bill Cooke), you probably might still be able to make it!

Yours,

Carla

The Brightest Moon of The Year


Here she is, rising over Grand Central Station.

Tonight, The Biggest, Brightest Full Moon of 2008!


Good Morning SuperForest!

SuperForester Casey just alerted us to a tasty fact:

If you get a chance tonight, go outside and look at the moon.

“Although a full moon happens every month, the one that rises tomorrow will appear about 30 percent brighter and 14 percent larger than the other full moons seen so far this year.

That’s because our cosmic neighbor will be much closer than usual. The moon will be at its closest perigee—the nearest it gets to Earth during its egg-shaped orbit around our planet.”

-Andrew Fazekas at National Geographic

Sweet! Big, bright moon.

Go and look at it with your sweetie.

Fun is the Sun!

I just came across this gallery of breathtaking new photos of our beloved sun!
Couldn’t help but think of SuperForester Carla’s excellent post “Keep Us Where the Light Is.”

The sun gets my vote for “object most desperately in need of re-deification.” I mean, sun worship is not really a new idea, but it’s a fairly convincing one. The sun IS directly responsible for all life on this planet, and when it “dies” it will take the entire solar system with it. Pretty compelling argument.

You might be convinced after checking out this gallery.

Love!

The Sombrero Galaxy

The Universe is such a big, wild, wonderful place.

From wikipedia:

“The famous Sombrero galaxy (M104) is a bright nearby spiral galaxy. The prominent dust lane and halo of stars and globular clusters give this galaxy its name. Something very energetic is going on in the Sombrero’s center, as much X-ray light has been detected from it. This X-ray emission coupled with unusually high central stellar velocities cause many astronomers to speculate that a black hole lies at the Sombrero’s center – a black hole a billion times the mass of our Sun.”
