Can an atom die?
No atoms themselves do not die, because they are not alive, they do make up the elements used to make live things but them are not alive.
If the thing that they made up was alive and that thing dies, and it biologically breaks down its atoms do not die, they may recombine but they do not die..
Is the space endless?
Our universe is just a finite number of galaxies rushing away from each other inside this empty infinite space—like a solitary skyrocket exploding and sending out a doomed shower of sparks.” But many cosmologists say, no, there are an infinite number of galaxies in our infinite space.
Is the universe infinitely small?
Your perception about the universe is right except the point that either side of the measuring reference does not extends to infinity. That is, there is no infinitely large or infinitely small. Everything is bounded at some value just unknown to us.
How fast is the Milky Way moving through space?
1.3 million miles per hourThe motion that’s left must be the particular motion of our Galaxy through the universe! And how fast is the Milky Way Galaxy moving? The speed turns out to be an astounding 1.3 million miles per hour (2.1 million km/hr)!
Can we survive without moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.
What is beyond the universe?
Astronomers think space outside of the observable universe might be an infinite expanse of what we see in the cosmos around us, distributed pretty much the same as it is in the observable universe.
How fast is the Milky Way moving towards Andromeda?
402,000 kilometers per hourCurrently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years.
Will our universe end?
Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.
Would a bullet fire 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’s the smallest thing in existence?
Though once thought to be fundamental particles on their own, in 1968 physicists found that protons and neutrons are actually made of quarks, which are indivisible. A proton contains two “up” quarks and one “down” quark. A neutron contains two down quarks and one up.
What is the smallest thing on earth?
Then the atom was discovered, and it was thought indivisible, until it was split to reveal protons, neutrons and electrons inside. These too, seemed like fundamental particles, before scientists discovered that protons and neutrons are made of three quarks each.
Is space and time infinite?
Temporal finitism is the doctrine that time is finite in the past. The philosophy of Aristotle, expressed in such works as his Physics, held that although space was finite, with only void existing beyond the outermost sphere of the heavens, time was infinite.
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 fast is space expanding?
72 kilometers per secondWendy Freedman determined space to expand at 72 kilometers per second per megaparsec – roughly 3.3 million light years – meaning that for every 3.3 million light years further away from the earth you are, the matter where you are, is moving away from earth 72 kilometers a second faster.
What is beyond outerspace?
If by outer space you mean all that surrounds the Earth and stretches into all directions as far as people can see, then you’re talking about what astrophysicists call the universe. For there to be anything outside of the universe supposes that it has an edge, which is a problematic supposition for physicists.
Has anyone been lost in space?
Soyuz 1 dooms cosmonaut: The first fatal accident in a space mission befell Soviet cosmonaut Vladimir Komarov, whose problem-plagued Soyuz 1 capsule crashed onto Russian soil in 1967. … The resulting drop in pressure also exposed the crew to the vacuum of space — the only human beings to ever experience such a fate.
What was before the universe?
The initial singularity is a gravitational singularity predicted by general relativity to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
