This dark spot on Mars could be an entrance to a deep hole, cavern or...
something even more UNBELIEVABLY FANSTASIC!

>330 feet (100 meters) across.
>Mars Reconnaissance Orbiter indicates it appears to be deep.
>not an impact crater, lacks a raised rim or tossed out material called ejecta.
>appears that any possible walls might be perfectly vertical.
>it's discovery is stimulating speculation about subsurface life on the planet.
>The deeper and deeper you go down on Mars, the warmer and warmer it gets where liquid water is stable and life could exist.

Just how dangerous is this scenario, anyway?

Thanks to movies like "Armageddon" and "Deep Impact", we all are aware of asteriods and comets and how they can crash into the Earth, causing death, destruction and doom for life here. (Actually, I knew this stuff even before such movies.) But the planet has had numerous near-misses over the years, and we think nothing of it--which is okay, of course. But the other day I was asked by my nephew about the moon's effects on the Earth's tides, and it just occurred to me that even a near miss by an object that is massive enough could cause serious problems for our world through its gravitational forces alone. My question is, how massive would such an object have to be before being a threat? For example, say a white dwarf star (or some other such star) goes supernova, and in the process throws out a fragment of white dwarf matter. How massive would that fragment have to be to cause gravitational chaos for the planet? I know it wouldn't have to be big; how massive would it need to be?

How does gravity work?

How does Earth know there is a Sun or a moon out there and it should be attracted to it? How does gravity work?

Black Hole?

Please describe what exactly a black hole is and what we, humans, know about it so far. What creates it, and do you think we will ever have the capability to manufacture one?

Can anyone explain abt my view of the universe ?

HI. this is my take on how the universe really is ...

I suppose that afterall the universe will not be ever expanding. as an analogy consider a circular plate. lets say a highly viscous liquid is poured at the plate center; the liquid starts to spread out circularly , it ultimately reaches the edge of the plate. then continues expanding, albeit in the bottom face of the plate ( lets forget gravity for now) . now it flows along the bottom face of the plate, and the liquid once again concentrates on the center of the bottom face of the plate, for a moment. then it again expands till the plate edge and then starts flowing on the top face of the plate and keeps flowing towards the center of the top face of the plate , until it is concentrated at the top face center... then guess wat,? it again does whatever is said above.. i feel this might be the case with the universe too,.with expansion towards concentration and congregation for the purpose of expansion. ..pls anyone can expand it ?

Layers curved in?

I have layers, but I really want them to curve like what you would see in the magazines.
My layers right now are like everywhere. They go like outwards and sometimes they just go their seperate ways!

Any suggestions?
