Reality check

[WD1979]

BEYOND OUR SUN IT'S A BIG UNIVERSE.

ANTARES IS THE 15TH BRIGHTEST STAR IN THE SKY.

IT IS MORE THAN 1000 LIGHT YEARS AWAY.

NOW, HOW BIG ARE YOU?

TRY TO WRAP YOUR MIND AROUND THIS...

THIS IS A HUBBLE TELESCOPE ULTRA DEEP FIELD

INFRARED VIEW OF COUNTLESS 'ENTIRE' GALAXIES

BILLIONS OF LIGHT-YEARS AWAY.

BELOW IS A CLOSE-UP OF ONE OF THE REGIONS OF THE PHOTO ABOVE.

HUMBLING, ISN'T IT?

NOW, HOW BIG ARE YOU?

AND HOW BIG ARE THE THINGS

THAT UPSET YOU TODAY?


KEEP LIFE IN PERSPECTIVE.




AND DON'T SWEAT THE SMALL STUFF!


IT'S ALL UNDER CONTROL!


LIGHT UP ANOTHER CIGAR AND RELAX.....​

 

[PJ the Comic]

Nicely done! :thumbs:

 

[MadMonk]

Very cool. I just spent a very enjoyable 20 minutes with my 5 year old, looking this over. Thank you!

I had tried a while back to find a comparison, but alas, my google-fu was not strong enough.

 

[grateful1]

Uranus is rather large! ???

 

[jlada]

The geek in my has come out..... not to be Timmy Technical, but if memory serves, that information regarding distance is off, as is the scale. Way off.


Edit: Oh, and Antares is smaller than Betelgeuse.

Yes, I'm an astronomy nerd.

How does that effect Uranus?

That could be the sign of a serious medical condition. Where's Doc when you need advice? :sign:

It also reminded me of this from when I was a kid.

 

[jlada]

THIS is actually needed to scale my anus, Gary.

 

[thinde]

Wise ASS cracks and scale issues aside, ya, I think we all need to remember where we are when things get sideways. Good job WD.

 

[Humidor Minister]

Some how made my problems very small today. Thanks, I needed that. :thumbs: I've always found Astronomy very fascinating. Nice job.

 

[The Green Monkey]

I love that sort of thing.

HERE's (click) a neat .gif that goes up a few levels of magnitude illustrating the same concept. I make no claims--expressly or implied--that the scale is accurate down to the micron. After all, I've never been to VY Canis Majoris.

Or Uranus, for that matter.

DAMMIT!

I just spent five minutes looking for that GIF and I finally found it, and just when I was about to post it, I saw your reply.

What I would like to know is it takes 365.256366 days for one orbit round the sun and 23h 56m 4.100s for the earth to rotate once on it's own axes.
So 365.256366 days in a year.
Every four years we ad an extra day to the calendar so that compensates for the 0.25 a year and leaves 0.006366 days.
That’s 9m10.0224s per year.
There's 24 hours on the clock so that's a difference of 3m5,900s per day.
3m5,900s X 365.256366 days is 18h39m41.1584394s
18h39m41.1584394s minus the 9m10.0224s that leaves 18h30m31.1360s or about 3m per day


What I would like to know is where does the 3 min go???

You mean the 3 minutes it took to read and re-read this POST!?


:laugh:

The International Date line eats it.

Actually, you are mistaken. The number 365.256366 you are quoting is a siderial year. Long story short, it's the time it takes the Earth to orbit the Sun once with respect to a fixed frame of reference (stars). This is often quoted as "true orbit time".

Our calendar works on the Julian year. A Julian year is precisely 365.25 "days". We're not losing 3 minutes of terrestrial time a day.

Time and day lengths vary dependent upon your frame of reference, and you've combined two different "year" references to measure differences in length in a "day".

You should, however, be very worried about THIS and THIS.
