What is the hardest question about space?

Is Time Travel Possible In Our Universe?

What are questions the universe can't answer?

What happens to us after we die? How did so much life appear on our planet when others seem devoid of any species at all? Who, if anyone, pulls the strings of our universe? Is it some all-powerful god in control or are there physical and mathematical principles driving the engine of our existence?

What is the most unknown fact about space?

There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. 2. THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C. Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Did you know that Venus isn't the closest planet to the sun?

What is the biggest think in the universe?

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure. For perspective, the universe is only 13.8 billion years old.

What is the ultimate question to the universe and everything?

The number 42 is especially significant to fans of science fiction novelist Douglas Adams' “The Hitchhiker's Guide to the Galaxy,” because that number is the answer given by a supercomputer to “the Ultimate Question of Life, the Universe, and Everything.”

What are some unanswered questions about space?

Who created dark matter?

The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.

Is space infinite?

Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.

What is the biggest mystery in physics?

What does 42 mean in physics?

42 is the number of galactic years that the Sun-Earth system will survive before it's destroyed. And 42 is the expansion rate of the entire Universe, in miles-per-second-per-megaparsec. It really could be the answer to the ultimate question about life, the Universe, and everything.

What is the nothing beyond the universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

How will the universe end?

Our cosmos is currently 13.77 billion years old, and galaxies throughout the universe will continue making new stars for many years to come. But eventually—roughly one trillion years from now—the last star will be born. That star will likely be a small red dwarf, barely a fraction of our sun's mass.

What is the universe question and answer?

The Universe consists of everything that exists anywhere in space. All the heavenly bodies such as the sun, the moon and the stars which are seen with the naked eye and many more celestial bodies such as planets, asteroids, satellites, comets, meteors, meteorite, which are not seen with the naked eyes.

What's at the end of space?

Practically, we cannot even imagine thinking of the end of space. It is a void where the multiverses lie. Our universe alone is expanding in every direction and covering billions of kilometres within seconds. There is infinite space where such universes roam and there is actually no end.

What is the most powerful thing in the universe?

These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe. What's more, these GRBs could be killing our chances of ever discovering life on other planets.

What is the oldest thing in the universe?

Methuselah: The oldest star in the universe | Space.

What's the rarest thing to happen in space?

Radioactive decay that takes place over trillions of years.

A dark-matter detector buried under 1500 metres of Italian mountain has recorded what is arguably the most uncommon phenomenon in the universe – the decay of a Xenon-124 atom.

What does space smell like?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [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'.
