Can fire only exist on Earth?

But do we know of fire anywhere besides on our planet? NASA's Galileo spacecraft saw shimmering, fresh lava in Io's Tvashtar Catena back in 2000. Jupiter's volcano moon holds the closest thing to earthly fire in our solar system.

Does fire only happen on Earth?

Earth is the only known planet where fire can burn. Everywhere else: Not enough oxygen. 6. Conversely, the more oxygen, the hotter the fire.

What planet is made of fire?

Venus is truly a world born of fire, evolved by fire, shaped by fire, and ultimately, as the Sun dies and swells up, to die by fire.

Can you have fire in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

Can fire exist without oxygen?

Air is made-up of about 21% oxygen, 78% nitrogen and less than 1% other gases including carbon dioxide and water vapor. Fire only needs about 16% oxygen to burn. Without oxygen, fires won't burn.

Elon Musk JUST WARNED Earth Won't Exist In 12 Years, People Don't Realize What's Coming!

Is the sun made of fire?

The Sun isn't "made of fire". It's made mostly of hydrogen and helium. Its heat and light come from nuclear fusion, a very different process that doesn't require oxygen. Ordinary fire is a chemical reaction; fusion merges hydrogen nuclei into helium, and produces much more energy.

Why is Blue fire the hottest?

Blue flames usually appear at a temperature between 2,600º F and 3,000º F. Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood.

Do guns work in space?

Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.

What does space smell like?

Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...

Can there be fire underwater?

With careful application, a sustained fire can be created even underwater. Plasma cutting is a procedure for underwater burning in Baltimore that cuts electrically conductive materials.

Is a lava planet possible?

There are no known lava worlds in the Solar System and the existence of extrasolar lava planets remains unknown. Several known exoplanets are likely lava worlds, given their small enough masses, sizes, and orbits. Likely lava exoplanets include COROT-7b, Kepler-10b, and Kepler-78b.

Was the Earth covered in lava?

Young Earth's molten lava ocean was layered like a pudding cake, according to a study published today (Nov. 6) in the journal Nature. Researchers think the Earth's first millennia were spent covered in magma, following a giant impact that formed the moon.

Can fire start on Mars?

We know that fire can only burn naturally on our planet, and Mars doesn't have a dense atmosphere or enough oxygen to allow flames to burn – but space station and spacecraft fires are a very real danger, and with crews living and working in close proximity, fire would be disastrous.

Can fire happen in other planets?

But do we know of fire anywhere besides on our planet? NASA's Galileo spacecraft saw shimmering, fresh lava in Io's Tvashtar Catena back in 2000. Jupiter's volcano moon holds the closest thing to earthly fire in our solar system.

Who invented fire?

Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 2.0 million years ago (Mya). Evidence for the "microscopic traces of wood ash" as controlled use of fire by Homo erectus, beginning roughly 1 million years ago, has wide scholarly support.

Why does fire exist?

Fire is the result of applying enough heat to a fuel source, when you've got a whole lot of oxygen around. As the atoms in the fuel heat up, they begin to vibrate until they break free of the bonds holding them together and are released as volatile gases. These gases react with oxygen in the surrounding atmosphere.

Do you age in space?

In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.

Can you fart in space?

The official verdict on gas in space: No burps, more farts, and no, you can't use your flatulence to propel you around the shuttle.

Will a body decay in space?

In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.

How cold is space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

Can you talk in space?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet.

Can we hear sound in space?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.

Can black fire exist?

This is black fire. When you mix a sodium street light or low-pressure sodium lamp with a flame, you'll see a dark flame thanks to the sodium and some excited electrons. “It's strange to think of a flame as dark because as we know flames give out light, but the sodium is absorbing the light from the lamp.

What is the coldest fire?

The Symbolism of Fire (Examples from Literature and Religion) Red flames are generally the coldest, and the deepest reds produce temperatures between 1000 and 1800 degrees Fahrenheit.
