Is the space infinite?
The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
What is bigger than a black hole?
However, even the most massive black holes aren't particularly large, since this type of structure is the densest in the universe. Nebulas, or vast clouds of gas that often condense to become new stars, also have impressively large sizes.
Is the universe infinite?
The observable universe is finite in that it hasn't existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
How many universes are there?
In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.
Is the Universe infinite?

What’s bigger than a Universe?
No, the universe contains all solar systems, and galaxies.
Is there color in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
What kills a black hole?
Black holes, the insatiable monsters of the universe, are impossible to kill with any of the weapons in our grasp. The only thing that can hasten a black hole's demise is a cable made of cosmic strings, a hypothetical material predicted by string theory. But there is reason to take heart.
Are we inside a black hole?

Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.
What are 3 things found in the universe?
The universe is filled with billions of galaxies and trillions of stars, along with nearly uncountable numbers of planets, moons, asteroids, comets and clouds of dust and gas – all swirling in the vastness of space.
Do we age slower in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
What’s the ugliest colour?
drab dark brown Pantone 448 C is a colour in the Pantone colour system. Described as a "drab dark brown" and informally dubbed the "ugliest colour in the world", it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was the least attractive colour.
Can we see color in space?
Read on to learn more about color in space. Believe it or not the human eye can see about 7,00,000,000 colors. But, did you know that colors exist that you cannot see? Color does not change in space, because the wavelengths remain the same.
What kills you in space?
REAL SPOILER ALERT: The short answer is that the lack of oxygen would make you black out after about 15 seconds. Then by about 90 seconds you are too far gone to be saved. So you would die from lack of oxygen well before the radiation and cold would have time to kill you.
Is there a white hole?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.
What if you nuke a black hole?

Are wormholes real?
Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They've never been seen, but according to Einstein's general theory of relativity, they might exist.
Can time be bent?
So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.
Has anyone been in a Blackhole?
Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system.
What is the rarest thing in space?
Ring galaxies, the rarest in the Universe, finally explained
- Almost every galaxy can be classified as a spiral, elliptical, or irregular galaxy. …
- With a dense core consisting of old stars, and a circular or elliptical ring consisting of bright, blue, young stars, the first ring was only discovered in 1950: Hoag's object.
Why is space silent?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.
How long is 1 year on the Moon?
27 daysMoon / Orbital period
Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
What is a rarest color?
But among all the hues found in rocks, plants and flowers, or in the fur, feathers, scales and skin of animals, blue is surprisingly scarce. But why is the color blue so rare? The answer stems from the chemistry and physics of how colors are produced — and how we see them.
What colors can we not see?
Red-green and yellow-blue are the so-called "forbidden colors." Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they're supposed to be impossible to see simultaneously.
