There is virtually no significant antimatter left in the observable universe today because matter and antimatter annihilated each other after the Big Bang, leaving a tiny imbalance (about one extra matter particle per billion) that resulted in the universe we see, with the missing antimatter converted into the vast number of photons seen as the cosmic background radiation. While small amounts of antimatter are constantly created and destroyed (like in particle accelerators or cosmic rays), it's too short-lived and scarce to account for the large-scale absence, which remains a major mystery in physics, CERN.
Satellite experiments have found evidence of positrons and a few antiprotons in primary cosmic rays, amounting to less than 1% of the particles in primary cosmic rays. This antimatter cannot all have been created in the Big Bang, but is instead attributed to have been produced by cyclic processes at high energies.
Scientists estimate 1 gram of antimatter would cost $62.5 trillion to produce. Why? Because when it meets matter, it unleashes 100% pure energy. Right now, we can only make a few nanograms per year inside particle accelerators — and it vanishes instantly if not perfectly contained.
Surprisingly, normal matter turns out to be only a small fraction of what the Universe contains. 95% of the Universe is made up of dark matter and dark energy. These are words astronomers have come up with to give a name to the mysterious, invisible side of the Universe.
The atoms that make up the world around us seem solid but are in fact over 99.99999 percent empty space. An atom consists of a tiny, dense nucleus surrounded by a cloud of electrons, spread over a proportionately vast area. This is because as well as being particles, electrons act like waves.
Quarks and gluons are the building blocks of protons and neutrons, which in turn are the building blocks of atomic nuclei. Scientists' current understanding is that quarks and gluons are indivisible—they cannot be broken down into smaller components.
Space, or outer space, is a vast, near-perfect vacuum largely devoid of matter. This vacuum contains very few particles compared with Earth's atmosphere. However, it's not entirely empty. Space is dotted with scattered matter called the interstellar medium, which includes hydrogen and helium atoms.
Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe. Here's a sobering fact: The matter we know and that makes up all stars and galaxies only accounts for 5% of the content of the universe!
There is no single, physical place that God resides in our Universe. Where is God? The Bible tells us that God is spirit and resides in His spiritual home, Heaven. It's not a physical place that can be experienced by our human senses.
The rarest thing to have ever existed in the universe is likely the first particles or moments of existence following the Big Bang. This includes phenomena like primordial singularity, quark-gluon plasma, or the extremely short-lived inflaton field responsible for cosmic inflation.
Antimatter may seem impossibly far from daily lives. But ordinary bananas produce antimatter , releasing one positron—the antimatter equivalent of an electron—about every 75 minutes. Neutrinos may be their own antiparticles.
Antimatter is not only a subject of immense scientific curiosity but also the most expensive material in the universe.
"The father of antimatter was the remarkable English physicist Paul Dirac (1902-1984), considered by many to be the greatest British theorist since Sir Isaac Newton." Dirac was awarded the #NobelPrize in Physics at the age of 31 in 1933 "for the discovery of new productive forms of atomic theory".
The Higgs boson, which is named for Scottish physicist Peter Higgs and is often called God's particle because of the deep secrets it could reveal, was described by theorists in the 1960s.
"Einstein's theory of general relativity says antimatter should behave exactly the same as matter," says University of California, Berkeley, plasma physicist and ALPHA collaboration member Jonathan Wurtele.
It thus consists of a significant portion of charged particles (ions and/or electrons). While rarely encountered on Earth, it is estimated that 99.9% of all ordinary matter in the universe is plasma. Stars are almost pure balls of plasma, and plasma dominates the rarefied intracluster medium and intergalactic medium.
777 is considered the number of God (or divine perfection) in Christian and biblical traditions because it's a powerful emphasis of the number 7, symbolizing divine completeness, perfection, and holiness, often linked to the Holy Trinity (Father, Son, Holy Spirit) and representing the perfect fulfillment of God's work, contrasting with the imperfection of 666 (Beast). While not explicitly named as God's number, its symbolism stems from the pervasive use of '7' for perfection in the Bible, like creation in seven days, with 777 being a triple reinforcement of this divine attribute.
Elon Musk's beliefs have evolved; while previously skeptical, he recently stated he believes "God is the Creator" and the universe came from "something," though he avoids strict religious labels, identifying more as a "cultural Christian" who values Christian principles for boosting happiness and birth rates, rather than subscribing to all traditional doctrines. He acknowledges a higher power but distinguishes this from a judging, moralistic deity, focusing on the creative origin of the cosmos.
About 95% of the universe is "invisible" because it's composed of dark matter (around 27%) and dark energy (around 68%), which don't emit, absorb, or reflect light, unlike the normal matter (stars, planets, us) that makes up the visible 5%. Dark matter's presence is inferred through its gravitational pull on visible galaxies, while dark energy is a mysterious force causing the universe's accelerated expansion.
In 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
We are extremely confident black holes exist due to overwhelming evidence like stars orbiting invisible, super-massive objects (Sagittarius A*), gravitational waves from merging black holes detected by LIGO, and direct imaging of their shadows by the Event Horizon Telescope (EHT). While "100% sure" is rare in science, the consistency between Einstein's relativity, observed phenomena, and these new direct proofs leaves virtually no doubt within the scientific community.
Together, dark energy and dark matter make up 95% of the universe. That's almost the whole universe! That only leaves a small 5% for all the matter and energy we know and understand.
But eventually, the lack of oxygen will take its toll. One by one, your major organs will shut down. After only a handful of minutes you will suffer complete organ failure, otherwise known in the medical community as death.
Return to the Moon
Artemis II, scheduled for launch between February and April sees the return of the first people to the Moon since Apollo 17 in 1972. Three American and one Canadian astronaut will orbit the Moon on a 10 day journey that lays the foundation for lunar landings in the coming years.
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves.
