What is the most toxic object?
Botulinum toxin
Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
What's the deadliest thing in the universe?
Gamma Ray Bursts (GRB) are one of the most powerful events in space which happen with the collapsing of a super massive star or collision of two black holes or neutron stars that are so bright we can see them for billions of light-years away.What is the strongest poison?
Pål Stenmark regards botulinum toxin – the world's most dangerous poison – as a set of building blocks he can redesign and give new functions. One aim is to produce new and more effective pharmaceuticals, including pain treatments.Is there a perfect poison?
Thallium has been banned for consumer use in the U.S. since 1972. It can be fatal in doses as small as a gram and has been called "the perfect poison" because it is difficult to detect in lab tests.What is the deadliest gas?
Nitrogen-It is the most prevalent gas in the atmosphere. Nitrogen comprises more than 75% of the air we breathe. Therefore, N2 is the most lethal of all destructive, dangerous, and toxic gases.
This Is the Most Dangerous Object Ever Created
Will the universe RIP?
If dark energy remains unchanging, space will expand indefinitely while increasingly isolated stars will slowly fade away and go cold, a phenomenon referred to as Heat Death. And if dark energy keeps accelerating the expansion of the universe, space itself will eventually be torn apart in the Big Rip.What is at the bottom of a black hole?
According to our best theory of gravity, Einstein's theory of general relativity, your spaghettified body would eventually end up at a 'singularity' – an infinitely small and dense point at the 'bottom' of the black hole.What is the death of the universe called?
The heat death of the universe (also known as the Big Chill or Big Freeze) is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy.What kills the most humans every year?
Cardiovascular diseases are the leading cause of death globally. The second biggest cause are cancers.How the universe will end?
Eventually, the entire contents of the universe will be crushed together into an impossibly tiny space – a singularity, like a reverse Big Bang. Different scientists give different estimates of when this contraction phase might begin. It could be billions of years away yet.Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.Will the universe end in ice?
Observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".Would you feel pain in a black hole?
While some have hypothesised that 'death by black hole' would involve a painful roasting, generally, physicists agree that if you get too close to the event horizon, your body would be 'spagettified' as the gravitational tidal forces stretched you apart.Can you feel pain in a black hole?
When you start feeling pain depends on the size of the black hole. If you're falling into a supermassive black hole, you'll begin to notice the tidal forces within about 600,000 kilometers (372,822 miles) of the center -- after you've already crossed the event horizon [source: Bunn].What kills you in a black hole?
The fate of anyone falling into a black hole would be a painful “spaghettification,” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification, the intense gravity of the black hole would pull you apart, separating your bones, muscles, sinews and even molecules.Will humans ever leave our galaxy?
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.Are we falling in space?
(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. Thus, the astronaut is falling. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.Does the multiverse exist?
Even though certain features of the universe seem to require the existence of a multiverse, nothing has been directly observed that suggests it actually exists. So far, the evidence supporting the idea of a multiverse is purely theoretical, and in some cases, philosophical.What gas can suffocate you?
Carbon monoxide, or “CO,” is an odorless, colorless gas that can kill you.What gas causes death?
When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can lead to serious tissue damage, or even death. Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel.Which gas is fatal if breathed in?
Carbon monoxide is an odorless gas that causes thousands of deaths each year in North America. Breathing in carbon monoxide is very dangerous. It is the leading cause of poisoning death in the United States.Will the earth ever freeze again?
Ice cores are cylinders of ice drilled through the thick sheets of Greenland and Antarctica. So it is very likely that Earth will turn cold again, possibly within the next several thousand years.What will be left after the universe dies?
Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black. All lingering matter will be gobbled up by black holes until there's nothing left.What is the big slurp?
Big Slurp. This theory posits that the universe currently exists in a false vacuum and that it could become a true vacuum at any moment. In order to best understand the false vacuum collapse theory, one must first understand the Higgs field which permeates the universe.
