Big storms are different on Jupiter. On Earth, huge hurricanes and colossal cyclones are centered on regions of low pressure, but on Jupiter, it is the high-pressure, anti-cyclone storms that are the largest. On Earth, large storms can last weeks, but on Jupiter they can last years.

On Earth, large storms can be as large as a country, but on Jupiter, large storms can be as large as planet Earth. Both types of storms are known to exhibit lightning.

The featured image of Jupiter's clouds was composed from images and data captured by the robotic Juno spacecraft as it swooped close to the massive planet in August 2020. A swirling white oval is visible nearby, while numerous smaller cloud swirls extend into the distance.

On Jupiter, light-colored clouds are usually higher up than dark clouds. Despite their differences, studying storm clouds on distant Jupiter provides insights into storms and other weather patterns on familiar Earth.

WHAT IS THE BLOCK UNIVERSE THEORY??

Blog#352

Saturday, November 25th, 2023

Welcome back,

Your birth is out there in space-time. Your death, too, is in space-time. Every moment of your life is out there, somewhere, in space-time.

So says the block universe model of our world.

According to the block universe theory, the universe is a giant block of all the things that ever happen at any time and at any place. On this view, the past, present and future all exist — and are equally real.

How can this be?

The block has four dimensions: three spatial dimensions — say length, height and width — plus a fourth temporal dimension, or time. Or let's make it easier, by visualising the block model of our world as a three-dimensional rectangle, or cuboid.

Two of that cuboid's dimensions (let's say height and width) represent two of the universe's three spatial dimensions.

The third spatial dimension in the above diagram is left out — the length of the cuboid — and replace it with time. At one end of the cuboid is the big bang. At the other is the very last moment of the universe. Maybe it's a big crunch.

The cuboid is filled with every event that ever happens. Where these events are in the cuboid represents their location in space-time. All events, including your birth and death, and this very moment as you read these words, exist somewhere in the block.

In the block universe, time doesn't pass

It often seems as though where we are "today" is present, and "yesterday" is past, and "tomorrow" is future.

It also seems the present moment changes too — after all, tomorrow it will seem as though tomorrow is present, and yesterday it appeared yesterday was present!

So from our perspective, it appears that time flows or passes. But in the block universe model, time doesn't flow.

In other words, in a block universe, there is no specific present moment, and "past" and "future" moments are relative.

Think about the idea of "here". I am here. You, while reading this, can truly say "I am here", even though your "here" is different to mine.

On the block universe model, talk about the "present" or "now" works just like talk of "here".

Remember last week when you said to your friend, who was late arriving for coffee, "now you're here"; or when, long ago, Caesar said, "I am now crossing the Rubicon"?

These claims are both true. That's because all it means to talk about the present, or now, is to talk about the place in time where you happen to be.

Since we are always located wherever we are (that's trivially true), everyone is located in the present, just as everyone is located at the place they call "here".

According to the block universe view, time or temporal relations of "earlier than" and "later than" exist. These relations hold regardless of where anyone is located.

So, suppose Bert the dinosaur is located earlier than Sally the dog. That relation between Bert and Sally holds, regardless of whether we are located earlier than Bert or later than Sally.

Bearing this in mind, it is possible to see how to make sense of the idea of past and future. Just as on this model "now" picks out whatever time I happen to be located at, "past" picks out any time (or events at those times) that are earlier than my location, and "future" picks out any times or events that are later than my location.

Does that mean we can travel in time?

If time is just another dimension, a lot like the spatial dimensions, does that mean we can travel in time?

The short answer is yes.

Of course, things are way more complicated than that. Travelling in time is clearly much more difficult than travelling in space. It might be very technologically costly to time travel, so perhaps it's not really something that, practically speaking, we can do.

But it's certainly possible.

We already know that travelling very fast will result in time dilation, so we know it's possible to travel into the future just by travelling very fast.

We can travel quite a way into the future if we can travel at some reasonable percentage of the speed of light. We also know how to travel into the past. We can do that by using wormholes, which are short cuts through space-time.

What glows there? The answer depends: sea or sky? In the sea, the unusual blue glow is bioluminescence. Specifically, the glimmer arises from Noctiluca scintillans, single-celled plankton stimulated by the lapping waves.

The plankton use their glow to startle and illuminate predators. This mid-February display on an island in the Maldives was so intense that the astrophotographer described it as a turquoise wonderland.

In the sky, by contrast, are the more familiar glows of stars and nebulas. The white band rising from the artificially-illuminated green plants is created by billions of stars in the central disk of our Milky Way Galaxy.

Also visible in the sky is the star cluster Omega Centauri, toward the left, and the famous Southern Cross asterism in the center.

Red-glowing nebulas include the bright Carina Nebula, just right of center, and the expansive Gum Nebula on the upper right.
