what is the evidence that universe is 13.7B years old?

[SelfSim]

.. I have a consideration on this. All those years are mathematical years, not real years. Given that, it could be that they point not to real years, but to some reality which may have to do not with real years but with some fact yet to be realized.

It is a fact that a year in astronomy is defined as being exactly 365.25 days, where each day is of 86400 SI seconds each.

So not really 'scientific blasphemy' then, is it?

I take it the term has been appropriated by science for use in their industry.

 

[AV1611VET]

Also, to bring it back to the OP topic, I do find the idea of scientists from all across the world meeting to go "Right! ... how old do we think the universe is?" like some cheesy pyramid scheme sales pitch.

Consensus is where it's at, isn't it?

Not at all. To appropriate means to take something, usually without the owner's approval. I highly doubt the South American fisherman would give a hoot if they were told that El Niño/La Niña were the accepted terms to refer to hot and cold currents in the Pacific. They'd already called them that. Why even get into a tizzy about it?

You seem to think so with Pluto...

 

[2PhiloVoid]

I think a more simple explanation will do the job for a "beginner".
Consider a bicycle running down the road. The linear momentum is the bicycle moving. The roational momentum is the wheels spinning while at the same time moving. The spinning of the wheels help keep the bicycle stable.

i remembered that rotational momentum is better known by the name anglican momentum
demonstration of angular momentum - Google Search

Yeah, my paltry memory seems to bring back that I encountered just a taste of this back in 8th grade physical science class, but I'm sure what we covered back then had little to do with what we're talking about here.

I guess I'm not clear as to why consideration of Angular Momentum has much to do with the age of the universe? I mean, I'm seeing lots of books on my shelf that say some things other than what you're implying (and I have some books that agree with your leanings too, really).

But why should I think one way or another, brother?

Why even get into a tizzy about it?

Science has a hypocritical side to it.

Joe Lab: I hear El Niño was responsible for that storm we had recently.
Frank Street: Why are you calling it that? If we call it "El Niño," then we'll have to call others "Thor" and "Quetzalcoatl" and "Ahura Mazda" and ...
Joe Lab: Don't be silly. It's El Niño, period.
Frank Street: Okay. "El Niño" it is.
Bunsen Baker: Hi, guys! They're at it again. Ten Commandments on the courthouse lawn!
Frank Street: Idiots! Don't they know if they post the Ten Commandments, then they'll need to give equal airtime to Thor and Quetzalcoatl and Ahura Mazda and ...!?

Ah, yes. The classic 'Make up a fake conversation to pretend that you have a point'.

Question for you: why is the Sahara desert called the Sahara when Sahara means desert?

 

[AV1611VET]

You seem to think so with Pluto...

There's a lot more that went into Pluto's demotion than meets the eye.

Says you.

 

[AV1611VET]

If you didn't see the point I made, then it's because you ... well ... didn't see it.

 

[Warden_of_the_Storm]

You had no point. And you also ignored my question: why is the Sahara desert called the Sahara when Sahara means desert?
Hint for the answer: sometimes it's better to keep an old name already in use then to try and come up with an entirely new name for no reason.

 

[AV1611VET]

Says you.

Along with a host of others:

"Public reception to the IAU decision was mixed. A resolution introduced in the California State Assembly facetiously called the IAU decision a "scientific heresy". The New Mexico House of Representatives passed a resolution in honor of Tombaugh, a longtime resident of that state, that declared that Pluto will always be considered a planet while in New Mexican skies and that March 13, 2007, was Pluto Planet Day. The Illinois Senate passed a similar resolution in 2009, on the basis that Clyde Tombaugh, the discoverer of Pluto, was born in Illinois. The resolution asserted that Pluto was "unfairly downgraded to a 'dwarf' planet" by the IAU." Some members of the public have also rejected the change, citing the disagreement within the scientific community on the issue, or for sentimental reasons, maintaining that they have always known Pluto as a planet and will continue to do so regardless of the IAU decision."

Note: Notice that Pluto will always be considered a planet while in New Mexican and Illinois skies?

Again, your fixation on Pluto is noted. So what?

And the Sierra Madre Mountains! Redundancy is spinning
seemingly out of control!

 

[AV1611VET]

You had no point.

Of course not.

I never do, do I?

Only academia can make points ... right?

And you also ignored my question: why is the Sahara desert called the Sahara when Sahara means desert?

I give up.

Why is the Sahara desert called the Sahara, when Sahara means desert?

Hint for the answer: sometimes it's better to keep an old name already in use then to try and come up with an entirely new name for no reason.

Especially if it blasphemes God ... right?

 

[AV1611VET]

So your attempt to compartmentalize has failed.

 

[Warden_of_the_Storm]

Of course not.

It makes a lot more points than you do.

Especially if it blasphemes God ... right?

Never once have you shown how it's even blaspheming.

 

[AV1611VET]

Don't forget Hesperopithecus haroldcookii.

I actually started a thread just for you on the very topic of 'So what?' with regards to Pluto.
