Purely biological humans are typically 7ft tall now, with lifespans of 120+*
For centuries now, the technological singularity has produced enormous wealth and prosperity throughout the solar system. Across-the-board improvements in healthcare, education and living standards have led to humans evolving into a race of giants – 7ft tall, muscular and highly athletic, with lifespans of 120+. Note that this lifespan refers to purely biological (non-cyborg) humans, who comprise a small minority by now. The vast majority of citizens have opted for genetic engineering and biotechnology upgrades that offer practical immortality.
The Pillars of Creation are no longer visible from Earth
The Pillars of Creation were vast, towering formations of interstellar gas and dust – part of the Eagle Nebula – located around 7,000 light years away from Earth. They became famous in the late 20th century when the Hubble Space Telescope observed them in detail for the first time, showing a trio of dramatic and eerily beautiful structures. These pillars, the tallest being seven light years in height, functioned as "stellar nurseries" for newly-born stars.
Later observations in the infrared part of the light spectrum revealed a nearby cloud of hot dust, believed to be a shock wave produced by a supernova. This was gradually destroying the pillars and blowing away their contents.* The appearance and movement of the cloud suggested that it would have destroyed the pillars about 6,000 years previously, in 4000 BC. However, given the finite speed of light – and the distance of 7,000 light years to the Pillars of Creation – it would take until the year 3000 AD for this destruction to be visible from Earth.*

Humanity is becoming a Type 2 civilisation on the Kardashev scale
The exponential growth of AI has allowed the manipulation of matter on scales barely dreamed of before. The largest structure now being built in space is a "Dyson Sphere".* This hollow shell is of such gargantuan proportions that its radius stretches from the Sun to beyond the orbit of Jupiter.
Under the direction of a Godlike superintelligence, vast swarms of automated, self-replicating ships are building it, using material from the asteroid field, Kuiper Belt and Oort Cloud.
The sphere's primary purpose is to harvest literally all of the energy output from the Sun: some 386 yottajoules (YJ) per second.* However, it also serves the function of shielding our inner solar system from gamma rays and other incoming hazards. Even the potential possibility of alien invasion has been taken into consideration during the sphere's design.
The interior walls have a gravitational field of 1G and are made from wholly new states of matter that were unknown to science in previous centuries. These can withstand the colossal tensile forces required to maintain structural integrity. This curved, impossibly large surface – equivalent to billions of planet Earths – is becoming a habitat for many sentient lifeforms, with portions being terraformed and given stable atmospheres, oceans and landmass. A sizeable percentage of citizens are now migrating to these strange artificial worlds. This includes a diverse mix of biological humans, as well as transhumans, synthetics, clones, androids, sentient animals and other communities. A series of additional Dyson Spheres are being constructed around neighbouring star systems – some even larger.
Having begun its journey to the stars in the 22nd century, humanity is reaching a landmark in its exploration of space. A region nearly 1,000 light years in radius has now been settled (or about 2 percent of the total length of our galaxy).
Polar reversal of the Earth
Polar reversals have occurred many times before in Earth's history - typically every 300,000 years. The last time was around 780,000 BC. This means the planet is long overdue for such an event.
From 1900 onwards, the intensity of Earth's magnetic field was known to be declining by six percent each century. By 3500, the poles are beginning to completely reverse.*
Charged particles from the Sun affect satellites and other near-Earth vessels which lack adequate protection. However, plants and animals on Earth are unaffected. During the reversal, the solar wind induces a sufficient magnetic field in the ionosphere, temporarily shielding the surface in the absence of the normal magnetic field.*
The Grand Unification Energy is witnessed
The first particle accelerators were small, terrestrial-based devices. In the early 21st century, they resulted in energies of only a few tera-electronvolts. By the middle of the 4th millenium, however, an accelerator covering the entire perimeter of our Solar System has been built. This becomes the single largest experiment in history – powerful enough to accelerate particles to a state known as the Grand Unification Energy, allowing the very earliest moments of the Universe to be simulated. The electromagnetic, weak and strong nuclear force (three of the four fundamental forces) are viewed for the first time at precisely the same strength: becoming effectively different aspects of a single force. Quarks and electrons, too, become the same, achieving another unification.*
Computer science is reaching its ultimate potential
The biological and technological descendants of humanity are attaining the perfection of computer science. Hardware and software are becoming the absolute fastest, most efficient they can ever possibly be, within the known laws of physics. All of the knowledge to do so has now been largely achieved. From this point onwards, computer science becomes obsolete as a field of study – the only "unknowns" left for researchers to discover will be in other areas of science.*
