Amazing And Astounding Facts

Recommended Posts

How about a thread containing amazing facts? Things that when you first heard them had you jumping out of your chair shouting WT f*cking F at the wife. Anything you like, doesn't have to be physics/space related, that's just what interests me.

1. The Schwarzschild radius. This determines the radius of a sphere and the amount of matter that would need to be squeezed into it to create a black hole. You would need to compress the entire Earth into a sphere of less than 1cm to create a black hole, the sun a couple of kilometres. The black hole at the centre of our galaxy is estimated to have a Schwarzschild radius of about 8 million kilometres, WTF!

2. The Planck length. Describes the smallest possible measurement with any meaning, 1.6 x 10-35 metres (Don't know how to show the minus 35 correctly with these fonts). This length is where spacetime becomes 'foamy' and quantum effects take over. An autopsy on a former Labour cabinet minister established that the planck length could be reached by dividing his brain only three times. In one notable case, the brain was believed to have possibly been smaller than the planck length.

3. There are 300 billion stars in our Galaxy, the Milky Way. Many of these stars will have some planets revolving around them; that's a lot of planets. Our galaxy is one of about 100 billion. That's just the observable universe, which may be a tiny part of the entire thing.

Nothing too technical gets my juices flowing.

The very fact that light travels at 186,000 miles per second and the closest star (apart from the sun of course) being 4.2 light years away, well, you do the maths!

Thinking about infinity (ie. living infinitely) boggles the mind too. Not that it would ever happen.

I am quite sure that even if I could live infinitely, there would still always be an unfeasibly slow queue in the local Co-op.

I find accents amazing. That in this country, people can talk in a completely different tongue, and yet they live only 30 miles apart.

Oooh here's a good 'un.

If you labelled all of the atoms in a glass of water and poured the glass into the sea then returned ten years later and scooped up a glassful of seawater, you'd still find some of the labelled atoms in the glass, regardless of where you tried this in the world.

Why? Because there are more atoms in a single glass of water than there are glasses of water in all the seas in the world! :o

The energy output of a Gamma Ray Burst, thought to happen when a 10+ solar mass star collapses into a black hole, is equivalent to the energy output of a billion trillion Suns. Or put another way over the few seconds that a gamma-ray burst occurs, it releases almost the same amount of energy as the entire Universe!

Orbiting satellites detect one burst on average a day, those that point in our direction. But its thought around one hundred occur each day in the universe somewhere.

If you put a pea in bucket every time you make love to your other half before marriage, and take a pea out every time you make love after marriage, you will never empty the bucket.

More seriously, the world of quantum mechanics is pretty whacky...two particles being able to occupy the same piece of space at the same time! Then there's time itself...some theories say that all time exists at once, in other words the day you were born and the day you die are in existence right now, however you are only able to experience any given fraction of the time "cake" at one time i.e the present as we see it. Just a theory, but based on hard science.

HubbleDeepFieldL.jpg

The Hubble Deep Field image is of a section of sky about the size of your fingernail at arms length.

In that one piece of sky, they found some 3,000 (visible) galaxies.

A typical galaxy, such as our own, is thought to contain somewhere between 200 billion and 400 billion stars.

:o

You're not actually sitting on that chair you're sitting on, your levitating slightly above it as the atoms in your body repel the atoms of the chair.

Trying to remember these now from Bryson's book;

On the beginnings of the universe Bryson introduces us to the idea of ‘singularity,’ an infinitesimal speck of proton invisible to the naked eye. Describing the Big Bang origins of the universe he says on page 28, “In a single blinding pulse, a moment of glory much too swift and expansive for any form of words, the singularity assumes heavenly dimensions, space beyond conception . . .. In less than a minute the universe is a million billion miles across and growing fast. In three minutes . . . we have a universe . . .. And it was all done in about the time it takes to make a sandwich.â€

I've just dug this book out again with a view to rereading it. Much of this was lost on me last time round.

It's a good book.

[pedant]

The first Hubble deep field was 5.2 arcminutes square the second, ultra deep field was 11 arcminutes square.

This is smaller than 1mm squared viewed at a distance of 1 metre.

[/pedant]

In otherwords, your scale of awesomeness needs to be upped a few notches, those images are from a much smaller point in the sky.

Also worth noting that NASA deliberately found the blackest, darkest, emptiest part of the night sky to look at. When you next look at the night sky, the space between the stars is actually filled with superclusters of billions more stars.

You only need 39 decimal places of pi to calculate the circumference of the known universe to the accuracy of the radius of a hydrogen atom.

Whenever life gets you down, Mrs. Brown,

And things seem hard or tough,

And people are stupid, obnoxious or daft,

And you feel that you've had quite eno-o-o-o-o-ough...

Just remember that you're standing on a planet that's evolving

And revolving at nine hundred miles an hour,

That's orbiting at nineteen miles a second, so it's reckoned,

A sun that is the source of all our power.

The sun and you and me and all the stars that we can see

Are moving at a million miles a day

In an outer spiral arm, at forty thousand miles an hour,

Of the galaxy we call the "Milky Way".

Our galaxy itself contains a hundred billion stars.

It's a hundred thousand light years side to side.

It bulges in the middle, sixteen thousand light years thick,

But out by us, it's just three thousand light years wide.

We're thirty thousand light years from galactic central point.

We go 'round every two hundred million years,

And our galaxy is only one of millions of billions

In this amazing and expanding universe.

The universe itself keeps on expanding and expanding

In all of the directions it can whizz

As fast as it can go, at the speed of light, you know,

Twelve million miles a minute, and that's the fastest speed there is.

So remember, when you're feeling very small and insecure,

How amazingly unlikely is your birth,

And pray that there's intelligent life somewhere up in space,

'Cause there's bugger all down here on Earth.

I want to know how long it takes for those molecules to be evenly distributed throughout the world's oceans

That is pretty amazing. And to think we still actually debate whether life exists elsewhere in the Universe.

That is, IMO, one of the most stupid debates ever. Other life does exist. End of story. You would have to be mental to consider otherwise. The chances must be litereally trillions to one.

Everyone in Wales is gay.

I know - crazy, but true. If you don't believe me - just find one and ask them.

Not true - there's only one per village.

Are you thinking of England?

1. Shepherds Pie was invented by the Greek god Pan.

2. The recently undiscovered Peanut Butterfly probably doesn't exist.

3. Marzipan was originally produced as a nerve agent for use during the Vietnam War.

4. Alan Hansen is really dead, the one you see on telly is a well made mannequin that is voiced by Sir Sean Connery.

5. All of the long sought after dark matter in the Universe is composed mainly of Marmite with small impurities of Vegemite.

6. Scientists are optimistic that they are close to discovering the cause of Basingstoke, it is hoped that a cure will follow.

7. Tony Blair is a Middle East Peace Envoy. (Really!)

No. That sketch on Little Britain was actually paid for by the Welsh Tourist Board. The true story ? There is actually only one NON gay in the village.

And that is the local chippy owner - Alberto.

Farmers in Wales only use buttons on their flies.

Because after a few years, the sheep worked out what the sound of a zip being undone meant.

And they say sheep are stooopid?
