Thanks, Alana, for sharing. Black holes are favorites of mine and many others I'm sure!

1 &2
An overabundance of water, whether is be rain, runoff, storm surge or or natural phenomena, etc. saturating low lying and coastal areas.

3. No

Man-made damns and waterways are bound to fail.
Leave it to the beavers and allow development sites to follow the natural course of rivers and streams and of course oceans.
People build in the stupidest places.

I'm glad I live on a hillside as I watch torrential rains impact our islands and the road outside my front door turns into a fast running streams which I am not stupid snuff to venture out into.

Know that's not exactly the answer you're looking for but just MHO.

Life on Earth: The Flood....

1. What is a flood?
A flood occurs when water overflows or inundates land that's normally dry.

2. What causes floods?
This can happen in a multitude of ways. Most common is when rivers or streams overflow their banks. Excessive rain, a ruptured dam or levee, rapid ice melting in the mountains, or even an unfortunately placed beaver dam can overwhelm a river and send it spreading over the adjacent land, called a floodplain. Coastal flooding occurs when a large storm or tsunami causes the sea to surge inland. (NG)

3. Does a 100-year flood occur once every 100 years on average?
The 100-year flood is a climatic average, that is, there is a one percent (1%) chance a 100-year flood will happen in any given year. (noaa).

What do you think?
Science simply does not have the answers...

Why does light have a universal speed limit?

c, the speed of light constant, is valued at 3x108 meters per second. But why this figure and not, for example, 4x1020 m/s? Is it a random digit pulled out of a bag of numbers when a new universe explodes into existance? It's currently impossible to know why the speed of light is the speed that it is... all we know is that our universe couldn't exist without this limit.

Dark energy

We can't see it and we can't feel it, but we can test for it, and nobody knows what it is. In spite of this, scientists think that it makes up around 70% of the universe. It was imagined to explain why galaxies don't just drift apart but instead accelerate away from each other. You can think of it as a repulsive gravity that pushes matter apart. How it works, however, is still a mystery.

Greetings everyone...
Trivia fun anyone? 😀

1. This Earth critter's rate of acceleration is 50 times that of the space shuttle during launch.

2. What is the loudest noise made by a living creature that can be heard even 500 miles away?

3. While you read this one sentence, around a million billion of these will pass through your body...What are they?
.......now they have already passed the Moon.....

4. Every hour it expands by a billion miles in all directions.

5. On our planet, where and what is 5,500,000 square miles in size?

1. A flea

2. A humpback whale

4. The Universe

5. Antarctica

Some additional information:

"....The two largest deserts on Earth are in the polar areas. The Antarctic Polar Desert covers the continent of Antarctica and has a size of about 5.5 million square miles. The second-largest desert is the Arctic Polar Desert. It extends over parts of Alaska, Canada, Greenland, Iceland, Norway, Sweden, Finland and Russia. It has a surface area of about 5.4 million square miles...."

Tammy and JJ, you are correct. Congratulations!

Do you want to test the imagination?

Space is bent towards an object, not around it....

Imagine that in the following models, the object shown in the diagrams is a supermax-sized star. The star is going to go 'supernovae' and it will collapse under its own weight. The result will be a Black Hole.

Question: While we have all seen science's depiction of a 2-dimentional Black Hole (you know the one with the funnel shape warping), what does the Black Hole look like in a 3-dimentional depiction that represents space as it 'bends towards the star from all directions?'

OK. Our Supermax Star has gone supernovae, collapsed under its own weight, and resulted in a Black Hole, which we are observing 3-dimentionally and not the inaccurately depicted 'trampoline with a funnel/ tunneling effect' as a result. Therefore, we must be now observing a 'disc' - a Black Hole 'disc' so dark that light cannot escape it.

QUESTION: What,then, is on the other side of this Black Hole?

Dust!

Dust!

🙂 Not dust...

Nothing......a void?

Nothing......a void?

Congratulations Daniel! Nothing is on the other side of a Black Hole. Nothing.

Question then: WHERE does everything go? We have no "down the well; down the funnel!' Yet the Black Hole is gorging itself on planets, moons, dust, star remnants...anything and everything in space *-)

I have to say sorry to JJ Swan. He said nothing but I didn't believe him.

Yes, Tammy. JJ, you were correct; there is nothing on the other side of the Black Hole. (tu)

"WHERE does everything go?" Nowhere, because nothing exists in a Black Hole.

"WHERE does everything go?" Nowhere, because nothing exists in a Black Hole.

I'm on the same page as you, Daniel, although I tend to waffle between yes and no regarding if, in fact, nothing exists within a Black Hole; this question is made manifest by Hawking's "information hypothesis in that information is not destroyed and might be retrievable and reassembled' from within a Black Hole. What do we do with Hawking?

In the meantime:

'....Picture an entire star collapsed down into a gravitational singularity. An object with so much mass, compressed so tightly, that nothing, not even light itself can escape its grasp.

The name “black hole” seems to have created something of a misunderstanding. And the images that show the gravitational well of a black hole don’t seem to help either.

So, if you were to jump into a black hole, where would you come out? What’s on the other side? Where do they take you to? Black holes don’t actually “go” anywhere. There isn’t an actual “hole” involved at all.

They’re massive black orbs in space with an incomprehensible gravitational field. We’re familiar with things that are black in color, like asphalt, but black holes aren’t that sort of black. They’re black because even light, the fastest thing in the Universe, can not escape their immense gravity....talk about 'escape velocity!'

And so, if you jumped into a black hole, you would then be instantly transformed … by those terrible tidal forces unravelling your body into streams of atoms… and then your mass would be added to the black hole.

Just so we’re clear on this, you don’t go anywhere. You just get added to the black hole.

If you did jump into a black hole, your experience would be one great angular discomfort and then atomic disassembly.

Let’s clear up the matter of that diagram. Consider that image of a black hole’s gravity well. Anything with mass distorts space-time. The more mass you have, the more of a distortion you make….And black holes make bigger distortions than anything else in the Universe.

Light follows a straight line through space-time, even when space-time has been distorted into the maw of a black hole. When you get inside the black hole’s event horizon, all paths lead directly to the singularity, even if you’re a photon of light, moving directly away from it.

So.... there’s nothing on the other side of a black hole, just disassembly and death....'

Enter Stephen Hawking: 😀
http://www.scientificamerican.com/article/stephen-hawking-hasn-t-solved-the-black-hole-paradox-just-yet/

Where do we go from here Swans? "Physicists have tried to find a way for the information to escape the black hole’s demise via the Hawking radiation. The problem with this scenario, however, is that black holes appear to have no way to impart information to this radiation. Black holes, in fact, are very simple objects according to the theory of general relativity, which first predicted their existence. They have only three properties: mass, charge and angular momentum; other than those quantities, they have no characteristics, no other details—in physicists’ vernacular, they have “no hair.” More reading to do for me.....

😀 Ha! I have no idea, Daniel, where we go from here...That has been the dilemma for Hawking and other physicists who are intense on understanding the Black Holes. Are we sure that the black holes even exist? You can't see them! They're too black and, if they truly exist and devour our photons, then we will have no light to ever spot them whirling about the universe! We may as well start searching for the Mini-Black Hole...you know, the one that is the size of an atom, but has a mass the size of a mountain? You know, the Minis, born at the time of and out of the Big Bang 14.5 billion years ago, that pass through the earth each year? The Minis who don't even sting you when you bump into them. (I still think one ate my house keys as I've been missing them for years now.)

We're headed in the right direction regardless of where we go from here, Daniel; the physicists are headed in the right direction too; but the only one who truly knows what this phenomenon is about is the Black Hold itself and it seems to know where it is headed and why....and that's all that matters....

So, now we know that Black Holes have no 'wells' (funneling) but, instead, are disk shaped; these are called 'accretion disks'. We also know that there is nothing on the other side of the Black Hole, yet everything goes into it and nothing ever comes out of it. Where, then, is all of this stuff located.... in the event horizon on the edge of the Black Hole? Let's take another step toward that accretion disk area....😀
