The Earth is Expanding!

[Science101]

That is interesting!

And it isn't a joke: http://en.wikipedia.org/wiki/Expanding_earth_theory

What I want to know is WHERE DID ALL THE WATER COME FROM?!

The first paragraph explains that it is not taken seriously by scientists:

The Expanding earth theory is an attempt to explain the position and movement of continents on the surface of the Earth. It has a relatively small following today, compared with the almost universally accepted theory of plate tectonics, and is considered to be discredited by mainstream geologists.

The water may have come from comets. They are like giant snowballs.

Spoiler Alert!

This isnt a real theory.....
I posted it because its a joke...

That will teach you! :giggling:

The first paragraph explains that it is not taken seriously by scientists:

But it isn't a joke then:

Samuel Warren Carey AO (* November 1, 1911 in Campbelltown; † March 20, 2002 in Hobart) was an Australian geologist who was an early advocate of the theory of continental drift. His work on plate tectonics reconstructions led him to develop the theory of the expanding earth.

And:

Very few geologists or geophysicists today support the expanded Earth.[1] Many of those that remain are proponents of the ideas of the late Australian geologist S. Warren Carey. While Carey's ideas were popular for a time in the 1950s and 1960s, most workers in earth science believe that evidence collected over the last several decades supports a fixed size Earth, due to subduction, over the expanded Earth.[attribution needed]

Here's the key:

While Carey's ideas were popular for a time in the 1950s and 1960s, most workers in earth science believe that evidence collected over the last several decades supports a fixed size Earth, due to subduction, over the expanded Earth.

Subduction happens on the other side of the plate. Or in other words, the plate moves sideways. At the mid ocean ridge the plate is added to, like this.

On the other side of the plate, it slides under another back into the earth.

Scientists have already deduced what happened to the single continent that once existed called Pangea. Notice that the planet is not growing in size, the plates are moving:

The expanding Earth theory was proven to be wrong.

 

[Malaikah]

No, I don't think so. The key is that MOST think the expanding earth theory is wrong. Which means it is not a joke, rather a real theory, even if it is unpopular.

 

[Science101]

I guess. But there are people who still believe that the earth is flat, humans rode on dinosaurs, and meat grew on trees, so it is still silly to believe them.

Science is always changing...we'll see how this theory runs along. Even my professor admitted that the information we get is the truth for that certain time and may not be later on. So lets see yea?

Geology and plate tectonics arnt exactly new fields. There are some holes left to be filled, the the majority of the info points really strongly that whats in the video is BS.

 

[Nσσя'υℓ Jαииαн]

I stand by what I said

 

[Science101]

All new information that has been found, only supports plate tectonic theory. The expanding earth model really is now on par with the flat-earth model. But maybe someday someone will prove that the earth is really flat. The earth being round is after all, just a scientific theory too...

 

[Science101]

I must add that you are right in a way because there are theories with little empirical evidence. These can go either way, such as "String Theory".

Then there are quack theories that are not even scientific, such as "Intelligent Design Theory". All that was in that theory that was claimed to be scientific was overwhelmingly proven to be false but the Christians who back it for political reasons still find people that will believe it's a real theory.

But since the 1950's scientists have gone from not knowing what is under the ocean and in subduction zones like California, to having instruments that allow them to measure the plate movement. And there is a wealth of evidence in geology showing how the pieces once fit together to become the supercontinent of Pangea. Dinosaur fossils record a time when they could walk from Massachusetts to North Africa then the route became ocean, evolution then records their diverging into separate species.

The modern plate tectonic theory is too well supported to go either way. Verifying that there are subduction zones and places continents crashed together to form mountain ranges ended the thinking that the plates were spreading in all directions like they would if the planet was swelling.

Dunno where you got that from, in my post. I really did just make a simple statement I never agreed nor disagreed with any of that.

Peace to you.

 

[Science101]

Excellent!

In either case, I thought it would be beneficial to elaborate on the point you brought up about theories for those who might not know much about them. You probably know how some people think they are just a guess (much like a "hypothesis"), when in fact they are actually the best explanation science has for something. And unlike "laws" that are easily stated in a few sentences or a formula, theories are just a mass of information science knows about something that can be added to and tweaked as science discovers more about it. Even in the worst case scenario like discovering that there is some slight swelling of the earth (might tend to shrink as it cools though) plate tectonic theory would never be replaced, just have that new info become a part of it.

And there I go again! Once I get started on a topic I am passionate about, I could go on forever! :heated:

Lol, I know what you mean. I happen to love science That's my field. Not specifically this topic but still science.

The Day that We roll up the heavens like a scroll rolled up for books (completed)

That verse gives me the idea that universe is essentially flat

 

[Woodrow]

That verse gives me the idea that universe is essentially flat

Oddly that concept fits in with the mathematics of topology. A topographical projection of the universe results in a circle that is infinitely large in diameter, but infinitely thin in thickness.

The answer is from what relationship to the universe are you viewing it. If you are a small finite creature living within the universe it is a sphere with an infinite radius. If you are an infinitely large Being viewing it from an infinite distance it could a flat circle.

 

[Chuck]

I think we can have another model of the fate of the universe. Most widely believed are big crunch or expansion forever, but it is possible that universe may roll back on itself like scroll rolls back. I see mathematical possibility with shape of the universe being flat.

Wow! Jazakallah! I just love Geography!

 

[sadia faisal]

Wow, interesting, gna look that up!

 

[ranma1/2]

Just a thought. I seem to recall that somewhere in the Qur'an we are told the universe is expnding. If the universe is expanding, and since we are part of the universe, isn't it logical that the earth is expanding?

Now if I can find the ayyats that refer to the universe expanding.

it would also make sense that we ourselves are expanding. This is evident around the 4th thursday of Novemeber, and the 25th of decemeber.
