How old is the universe...? And, How big is the universe...? Discussion...?

[Neogaia777]

The simple answer is that scientists have accumulated data about the motions of the elements of the universe (stars, planets, galaxies, etc.) ... and concluded that everything is moving away from each other (most like the particles flung apart in the aftermath of a great explosion).

From this, they have theorized the "Big Bang", or, as I like to call it, the "Let there be Light" moment. Extrapolating back using the current distances and outward movement of the various elements of the universe (and doing the math), ... it is theorized that this "explosion" took place some 15 billion years ago.

Using data from years, many decades ago, but it's outdated now... We have new information that changes some of those theories I think... Or at least challenges them...

God Bless!

No, that is still what they think. What has changed is that it was once thought that gravity would be slowing down the rate of expansion, but it is instead speeding up, for some far from understood reason.

What is the average age and longevity of an average galaxy...?

How do galaxies form and how long does that take...?

Galaxies began forming about a billion years after the origin of the universe. Roughly speaking all galaxies today are about the same age. Over time, some galaxies have collided and been disrupted or merged together.

If we think the universe could go on longer than this for trillions or more years, why do we think it is only 13.8 billion years old...?

The universe is expanding now and becoming less dense. If we imagine 'running the film backwards', the universe becomes more and more dense until we get to a point where the density would shoot towards infinity. That point, colloquially known as the Big Bang, was about 13.8 billion years ago.

But, what's beyond that?

One theory suggests that the universe wraps around, like the surface of a sphere - go far enough in one direction and you'll end up back where you started. Of course the real answer is that we just don't know.

I know but, to me that does not make sense??
Got to be something beyond the warp?
Well, maybe not if that is the way in which God made it?

A lot of things in physics don't make intuitive sense. That said, we are still learning. We know comparatively little about the extent of the universe right now.

Again that would depend on how you define universe.

Simple question(s):

How old is the universe...? And, How big is the universe...?

Discussion...?

God Bless!

Totally unknown.....

The age is based upon their galactic evolution models, but their models have already been shown to be in serious error......

So you can be sure just about everything they claim is made up fantasies. Fantasies because they can't even tell you what 95% of the universe is, but want you to believe they can tell you how and when it formed. lol, don't you just love peoples vivid imaginations.....

No, a lot of things don't make intuitive sense because that's how they want you to think and accept it so they can sell you the next illogical unproductive search for the next billion dollars of your tax money down the drain for the next dark thing they can con you into buying....

Why bother with science since it doesn't even have to be logical anymore and people go right on willingly throwing their tax money down the drain to charlatans....

Science is the pursuit of observing the world and how it works.

Engineering (of which I am a participant) involves taking known science and utilizing it for the benefit of mankind ...

Together Science and Engineering have provided us with ...

Automotive travel
Air travel
Home construction
Plastics industry
Internet
Cameras
Phones
Can openers
Mass food production
Electric energy
Disease treatment
Radio
Television
Water processing and distribution
Batteries
Air conditioning
Heat Pumps
Eyeglasses
Dental Treatment/Repair
etc.

I used to design and model in 3D bridges, tunnels, dams, oil rigs, etc, so am quite aware of what science and engineering is......

Not disputing science, just some peoples philosophical interpretations of science..... None of the things you mention have any bearing on whether or not the interpretation of how long galaxies take to form is correct or incorrect. Incorrect according to the data.... Don't confuse science with interpretations of the observable world..... One may have no relation in the interpretation with the other, even if couched in scientific terms.....

Real science stopped decades ago when people started learning by rote instead of deductive reasoning. All we do now is improve upon the science from the past. Whether that is a better TV, batteries, heat pump, camera, car, etc, etc, etc.....

it's because of specialization. Every branch has to take the word of the other because they can't deduce for themselves whether the other branch is correct or not. Unlike the pioneers of science like Guass, Maxwell, Weber, etc who were versed in multi-disciplines, and therefore were able to reason out the science....

Yeah yeah, we've all heard this same old song and dance from you before. Come back once you overturn all modern theories of physics and win a Nobel Prize and then maybe we'll take your ramblings seriously.

How old is the universe...?

Very young, compared to eternity.

And, How big is the universe...?

Very small, compared to infinity. A perfectly cozy little place, from where I'm sitting.

Why do you expect that what science discovers must make intuitive sense? The nature of the universe may ultimately be incomprehensible to us.

How old is the universe...?

It is as old as God willed it.

And, How big is the universe...?

Its known size is 46 billion light years in length; but is actually larger than that.

Take a balloon and blow it up with smoke ... say to a diameter of 100 miles.

Now, in a split second, expand the walls of that balloon to a preset diameter ... say to 1000 miles.

What happens?

The smoke begins to expand into the newly-created space.

So far, we know the "smoke" is at 46 billion light years across; but we don't know how big the walls of the universe are.

In other words, we don't know how much space is between the smoke and the outer wall.

 

[Brightmoon]

That’s not a bad description if you think of the smoke as the visible universe

 

[Neogaia777]

Only that's not exactly the way it works, but I wasn't going to say that though...?

It accounts for a universe that is both expanding and expanded.

 

[Brightmoon]

Astronomers can see back into time over 13 billion years by looking into space. We see the universe get hotter and more opaque (because the universe is denser)the further back they look . The Big Bang is still occurring;the universe is still expanding!
