Quasars don’t last long—so how do they get so massive

Quasars are powered by supermassive black holes that devour surrounding matter at incredible rates, releasing tremendous energy across the electromagnetic spectrum.
Recent observations of billion-solar-mass black holes challenge conventional growth models in astrophysics, as they were observed at redshifts when the universe was less than a billion years old.
Studies suggest that these early quasars have surprisingly short active lifetimes of less than a million years, prompting researchers to explore alternative growth mechanisms like episodic super-Eddington accretion and black hole mergers.
Observations using the Very Large Telescope's MUSE reveal that distant quasars have only recently started intense accretion, challenging current understanding of supermassive black hole growth in the early universe.

The universe may die sooner than expected

Astrophysicists' current models suggest the universe could end in around 10¹¹⁰⁰ years, but new calculations indicate it could end much sooner due to the nature of black hole particles.
A study published in the Journal of Cosmology and Astroparticle Physics suggests that stellar remnants due to decay could take only 10⁷⁸ years before the universe's demise, attributed to Hawking radiation.
Hawking radiation, theorized by Stephen Hawking, introduces a scenario where particles can escape black holes, causing a slow decay of the universe over time.
The revised calculation considering Hawking radiation puts the demise of the universe at 10⁷⁸ years, affecting objects like white dwarfs, neutron stars, and black holes.

Dams Fill Reservoirs With Sediment

Dams naturally fill with sediment over time as rivers carry water and sediment.
Sediment falls out of suspension in slower-flowing reservoirs, creating colorful strata.
Long-term dam plans must address the challenge of sediment build-up, which is a complex and costly issue.
Dealing with sediment accumulation requires careful planning and investment in infrastructure.

Scientists Say: Lepton

A lepton is a type of elementary particle which is believed to not be made of anything smaller.
Leptons come in six types, including the electron, muons, tauons, and three flavors of neutrinos.
Leptons do not undergo the strong force, and they all share the same half-integer spin pattern.
While leptons vary in weight and electric charge, neutrinos, a type of lepton, have no electrical charge and can pass through most matter.

Can You Subtract the Numbers Without a Calculator?

To subtract one from a series of twos, evaluate 2²² without a calculator by breaking it down using the power rules.
Factorizing 2²² yields 2¹⁰ * 2¹², and using the value of 2¹⁰ as 1024, the calculation is simplified further.
After multiplication, the number 2048 can be split into 2000 and 48, which could be expressed as a sum of squares and then simplified using the square of a sum technique.
By breaking down 48 into 40 and 8 and following the same method, the calculation becomes simpler and attainable without a calculator.
