There are strong reasons for believing that space goes on beyond the limits of our observational horizon. There are strong reasons because if you look in opposite directions, conditions are the same to within one part in 100,000. So if we are part of some finite structure then, if the gradient is so shallow, it is likely to go on much further.

Because of its gradient, it is the site of many spectacular waterfalls, like the Unchalli Falls, near which, on a full moon night in winter, you might even glimpse a moonbow - a rainbow generated from the moonlight. This is the river Aghanashini - 'the cleanser of sins.

A lot of our fiscal deficit went to fund consumption and really did not get used to build investment and infrastructure. The trouble is, you can get a spurt in GDP growth, which may not be sustainable. I would much rather build the gradient of a long-term marathon.

Low socioeconomic status carries with it an enormously increased risk of a broad range of diseases, and this gradient cannot be fully explained by factors such as health-care access.

Brexit is a cliff, not a gradient. The mistake we are in danger of making is to believe that some Brexits are better than others when the fundamental problem is Brexit itself.

We don't know why, but there are some gradients of infection.

Imagine a hill when thinking of graph gradients - steepness indicates rapid change.

Graph Visual

Positive gradient goes up to the right, while negative descends to the right.

Positive vs Negative

In physics, a gradient may represent differences in concentration, temperature, or pressure.

Varied Rates

A gradient can map where a physical quantity changes, often shown on graphs or maps.

Visualize Change

Gradients refer to subtle or gradual transitions, not abrupt changes.

Subtle Shifts

Gradient isn't just visual; it can describe changes in sound, taste, or feeling.

Across Senses

Geographical gradients can affect travel difficulty and indicate landscape changes.

Terrain Changes

In geography, consider a gradient's effect on construction, water flow, or erosion.

 That's what happens along a concentration gradient, as substances shift passively from a high, or squashed, concentration, to a lower, more comfortable one. How does this relate to ocean currents and thermohaline circulation? Thermo means temperature, and haline means salt because in the real world scenario of the sea,

 amazingly, there is an electrical gradient, head to tail, that's generated that tells the piece where the heads and the tails go and in fact, how many heads or tails you're supposed to have. So what we learned to do is to manipulate this electrical gradient, and the important thing is that we don't apply electricity.

 to better constrain the problem and better understand the system, but from what the data is telling us now, it looks to be the result of a large hydrothermal system. Basically, it works like So, the deeper you go into the earth, the hotter it gets. We refer to this as the geothermal gradient.

 The first life form wouldn’t have had other organisms to consume, of course, so it must have been an autotroph, generating energy either from the sun or from chemical gradients. So what locations meet these criteria? Places on land or close to the surface of the ocean
