Another way to look at it, the visible universeis about 98 billion light years in diameter; the diameter of theearth about 0.04 light seconds, or 98 billion yearsto 0.04 seconds. In scale to the universe, the earth(any planet really) is tiny tiny tiny.
Similarly, you may ask, how big is earth compared to the universe?
It has an estimated 350-billion large galaxies(like the Milky way). It houses about 30-billion-trillion stars;that is 30,000,000,000,000,000,000,000 stars! The Earth isabout 3.5 million times larger than a human. The Solar System isabout 36 billion times larger than Earth (3.6 X10^10).
Additionally, is a galaxy or universe bigger? The Milky Way is big, but some galaxies, like ourAndromeda Galaxy neighbor, are much larger. Theuniverse is all of the galaxies – billions ofthem! NASA's telescopes allow us to study galaxies beyondour own in exquisite detail, and to explore the most distantreaches of the observable universe.
Keeping this in consideration, how big is the universe in miles?
The radius of the observable universe istherefore estimated to be about 46.5 billion light-years and itsdiameter about 28.5 gigaparsecs (93 billion light-years,8.8×1023 kilometres or 5.5×1023miles).
What is size of the Earth?
How long is a Lightyear in years?
A light-year is the distance light travels in oneyear. How far is that? Multiply the number of secondsin one year by the number of miles or kilometers thatlight travels in one second, and there you have it: onelight-year. It's about 5.88 trillion miles (9.5trillion km).
How many galaxies are they?
All in all, Hubble reveals an estimated 100 billiongalaxies in the universe or so, but this number is likely toincrease to about 200 billion as telescope technology in spaceimproves, Livio told Space.com.
What is the biggest planet on Earth?
Largest Planet: Jupiter
The largest planet in our solar system by far isJupiter, which beats out all the other planets in both massand volume. Jupiter's mass is more than 300 times that ofEarth, and its diameter, at 140,000 km, is about 11 timesEarth's diameter.
What is the universe made of?
The Universe is thought to consist of three typesof substance: normal matter, ‘dark matter' and ‘dark energy'.Normal matter consists of the atoms that make up stars, planets,human beings and every other visible object in theUniverse.
What is the biggest thing in the universe?
What's the Most Massive Object in the Universe? Agalaxy pileup of 14 merging galaxies known as SPT2349 is currentlythe biggest known object in theuniverse.
What does the black hole mean?
A black hole is a place in space where gravitypulls so much that even light can not get out. The gravityis so strong because matter has been squeezed into a tinyspace. This can happen when a star is dying. Because nolight can get out, people can't see black holes. They areinvisible.
What are we in the universe?
The Universe is all of space and time and theircontents, including planets, stars, galaxies, and all other formsof matter and energy.
What is our solar system called?
The Latest. Our solar system consistsof our star, the Sun, and everything bound to it bygravity — the planets Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto,dozens of moons and millions of asteroids, comets andmeteoroids.
Will the universe end?
The geometry of the universe is, at least on avery large scale, elliptic. In a closed universe, gravityeventually stops the expansion of the universe, after whichit starts to contract until all matter in the universecollapses to a point, a final singularity termed the “Big Crunch”,the opposite of the Big Bang.
How fast is the universe expanding?
In 2001, Dr. Wendy Freedman determined space toexpand at 72 kilometers per second per megaparsec – roughly3.3 million light years – meaning that for every 3.3 million lightyears further away from the earth you are, the matter where youare, is moving away from earth 72 kilometers a secondfaster.
How far does outer space go?
How many planets are in the universe?
Is dark matter matter?
Dark matter is a form of matter thought toaccount for approximately 85% of the matter in the universeand about a quarter of its total energy density. Most darkmatter is thought to be non-baryonic in nature, possibly beingcomposed of some as-yet undiscovered subatomicparticles.
What happens to a human body in space?
In space, astronauts lose fluidvolume—including up to 22% of their blood volume. Because ithas less blood to pump, the heart will atrophy. When gravity istaken away or reduced during space exploration, the bloodtends to collect in the upper body instead, resulting infacial edema and other unwelcome side effects.
How wide is the visible universe?
93.016 billion light years
How big is the unobservable universe?
46.508 billion light years
How big is the universe in simple terms?
It is estimated that the age of the Universe is13.73 (± 0.12) billion years, and that the diameter of theUniverse is at least 93 billion light years, or 8.80×1026 metres.
Is there a mirror universe?
The Mirror Universe is a parallel universein which the plots of several Star Trek television episodes takeplace. It resembles the fictional universe in which the StarTrek television series takes place, but is separate from the mainuniverse.
How many galaxies are there in the Milky Way?
250 billion ± 150 billion
