The cloud relies on hardware infrastructure with real-world limits

Microsoft's Azure cloud computing platform serves customers in 140 countries

Rather than owning and maintaining hardware on-premises, cloud computing enables users to access large reserves of storage and processing power over the internet, much like customers connect to a utility provider rather than generating their own electricity. This centralization also standardizes security tools and updates.

Most data centers rely on the local power grid to feed power-hungry computer equipment

These facilities house rows of vertical racks containing multiple types of hardware, including servers that provide 24/7 access to online applications, services, and data. In a hyperscale center with thousands of these racks, the annual electricity used is estimated to equal that of 400,000 electric vehicles.

AI data center growth has created shortages and price hikes in computer parts

The parallel processing needed to power large language models for AI chatbots and other tools drove demand for high-speed graphics processing units to spike in 2025, enabling capital-rich technology companies to price out consumers. Similar demands for the computer memory used in storage drives are expected to keep shortages from easing through 2028.

DNA computing allows for storage and processing of massive amounts of data

Although costly and less efficient for simpler tasks, as of 2025, DNA could hold 455 exabytes of data with near limitless parallel computation potential in small data centers. Every movie ever made would fit inside the volume of a single sugar cube.

Clouds' subtle climate effects require significant computational power to simulate

Responsible for reflecting sunlight and preventing thermal energy from entering the Earth system while also trapping energy and keeping it in the system, clouds are understood to substantially influence climate predictions. Because even supercomputers struggle to accurately model their dynamic behavior, researchers have used AI to indirectly incorporate clouds into climate models.

The internet explained at five levels of difficulty, from protocols to internet flattening

Resembling a roadway with traffic laws that all cars must follow, the internet is the hardware that connects a source to a destination, and these connections must follow specific software rules. Although data had to travel through about 10 networks to reach a destination in the past, data centers increasingly consolidate traffic, just as a highway does for cars, to improve data speeds.

As of 2025, there are no federal laws involving privacy and smart city technologies

Advancements in cloud technology and artificial intelligence allow cities to capture, store, and analyze more information than ever before. Experts warn that the unhindered ability to collect and use this data may infringe on residents' rights and endanger them if the data gets into the hands of malicious parties.

If the universe is infinite, it may be impossible to say what's beyond it

The universe is defined as all that exists, including space and time. If the universe is infinite, as observations currently suggest, there is no boundary from which we can ask what lies beyond.

Web crawlers and internet archives and back-ups limit perfect erasure of online data

Crawlers are programs that automatically browse the internet for links and index pages for search engines to pull up when page content matches search queries. Networks of global data centers also create copies of content as fail-safes for potential failures to ensure access isn't ever lost.

Only 21 million bitcoin will ever be created—what happens then?

Bitcoin is a popular cryptocurrency with a finite supply, and the issuance of new bitcoins is currently offered as a reward for verifying the transactions on the blockchain. Experts say the currency won't reach its limit until the year 2140, and miners may ultimately rely on transaction fees.

Despite claims of limitless free energy, zero-point energy cannot be harnessed

Because quantum mechanics prevents systems from ever reaching an energy value of zero, a seemingly empty vacuum of space still contains some amount of energy associated with its lowest allowed state. Since descending to even lower states is forbidden, extracting meaningful amounts of energy from an empty vacuum is impossible.

Play Infinite Craft, an AI software-powered game

Noise and instability made quantum computing seem out of reach for decades

Recent advances in error suppression, mitigation, and correction are allowing quantum computers to perform practical tasks that challenge classical machines. IBM’s 2016 launch of its first cloud-accessible quantum computer attracted over 22,000 users in its first month alone.

Cloud 9 is a dark-matter-dominated failed galaxy

Identified in 2023, the starless, gas-rich object is the first of its kind seen by astronomers and provides a window into the early stages of galactic formation without observations relying on visible matter as a proxy. The existence of such REHLICs, or Reionization-Limited-H I Clouds, was predicted by cold dark matter cosmological models.

An overview of helium, the nonrenewable resource that's lighter than air

The second element in the periodic table naturally forms deep underground over the course of billions of years through the decay of radioactive elements, but it is used and lost to space at rates faster than it is generated. Because of this and its extensive applications in scientific technologies, scientists continue to seek avenues for its exploration, storage, and recycling.

Billionaires are racing to space to control future markets

Although different companies have described focuses ranging from luxury tourism to Martian space colonies, all are building infrastructure to capitalize on the shift away from government-only control and betting big on reusability and scale. By securing public contracts and subsidies, they aim to develop strategic partnerships toward dominance in low Earth orbit.

Are you a digital hoarder? There are four types, actually

Digital hoarding: the phenomenon where people accumulate excessive digital clutter, like thousands of emails, hundreds of open browser tabs, and unused apps on their devices. This behavior has been associated with increased stress levels and potential negative impacts on mental well-being. Are you a digital hoarder? Find out the four types here.

Spare capacity is the amount of oil production that can be brought online within 30 days and sustained for at least 90 days

Specifically, a country’s “spare capacity” signifies the difference between its maximum sustainable oil production and its current output. OPEC member countries hold nearly all of the world’s spare oil production capacity. Historically speaking, Saudi Arabia has been the country with the largest spare capacity.

Cells cannot grow forever due to escalating inefficiency in transporting chemicals

As cells get larger, their volume grows much faster than the surface area through which nutrients and waste products pass, creating a bottleneck that eventually causes cells to die. This forces nearly all organisms visible to the naked eye to comprise enormous numbers of smaller cells, such as the approximately 30 trillion found in the average adult human.

How Amazon operates a 'flywheel' business model, a self-reinforcing cycle that drives continuous growth

Why content disappears from streaming services

The early days of streaming suggested we'd have access to all the world's content whenever we wanted. Those days are now long behind us, with streaming companies removing hundreds of movies and shows from their services, including titles they funded. This explainer from the Guardian argues that the reasons behind this shift are both financial and cultural.
