How cold is space?
Hot things move quickly, cold things very slowly.
If atoms come to a complete stop, they are at absolute zero.
Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit)..
How cold is liquid oxygen?
Liquid oxygen has a density of 1.141 g/cm3 (1.141 kg/L or 1141 kg/m3), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 101.325 kPa (760 mmHg).
What is the coldest natural thing on earth?
The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
What’s the smallest heaviest thing in the world?
The Neutron is the tiniest and heaviest thing known to man kind. It is a subatomic particle. … Osmium is one of the heaviest materials available on earth. Symbol Os; Atomic number 76; Atomic Weight 190.23; Density of 22.59 g/cm3. … Tennessine is the heaviest of man-made elements.
What is the fastest thing in the world?
Laser beams travel at the speed of light, more than 670 million miles per hour, making them the fastest thing in the universe.
Can liquid hydrogen kill you?
Liquid hydrogen wouldn’t be as reactive, but it the extreme cold and rapid expansion would do a lot of damage, and I’d guess it would be at least as deadly as drinking liquid nitrogen.
Is Absolute Zero Possible?
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.
What is the coldest substance known to man?
Liquid hydrogenLiquid hydrogen is the coldest substance known to man, minus 400 degrees. ALSO: A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 K, ?
What’s the rarest thing in the universe?
Astatine”Astatine remains the only element whose discovery was confirmed by a nonprimate,” writes Sam.
What is the hottest place on earth?
In July 1913, observers in Furnace Creek, California—Death Valley—watched the thermometer reach 56.7°C (134°F) and declared it to be the highest temperature ever recorded on Earth.
Is 0 Kelvin possible?
On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin. … At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears.
How cold is absolute zero?
Stranger still, absolute zero isn’t even zero on the temperature scales used by nonscientists. It’s minus 273.15 degrees on the Celsius scale, or minus 459.67 degrees Fahrenheit.
What is the coldest thing in the universe?
The protoplanetary Boomerang Nebula, located 5,000 light-years from Earth, holds the record for coldest known object in the Universe. Outflows of gas, streaming out from the central dying star, reach temperatures below -270 degrees Celsius.

Can liquid nitrogen kill you?
The fact is liquid nitrogen is dangerous if not handled properly. It can cause frostbite or cryogenic burns and if used or spilled in a confined space, liquid nitrogen – which is colourless, odourless and tasteless – can kill you.
Is liquid nitrogen the coldest thing on earth?
Yes, there are things colder than liquid nitrogen, like most of the Universe! … On Earth, none of these gases naturally exist as a liquid. They are only liquids when someone has made them into a liquid by artificially cooling them.
What’s the heaviest thing in the universe?
So massive stars become neutron stars – the heaviest things in the universe – and even more massive stars become black holes.
What is the heaviest organ in the human body?
The largest solid internal organ is your liver. It weighs approximately 3–3.5 pounds or 1.36–1.59 kilograms and is about the size of a football. Your liver is located beneath your rib cage and lungs, in the upper right area of your abdomen.
