What is the most expensive thing in the universe
16 PsycheAn astroid named 16 Psyche, after Cupid’s wife, was found to be made almost entirely of iron and nickel.
That means, in current US markets, 16 Psyche is worth somewhere around $10,000 quadrillion (the world’s economy is around $74 trillion)..
Which universe do we live in
the Milky WayOur home galaxy, the Milky Way, contains at least 100 billion stars, and the observable universe contains at least 100 billion galaxies. If galaxies were all the same size, that would give us 10 thousand billion billion (or 10 sextillion) stars in the observable universe.
What galaxy is earth on
the Milky WayEarth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way. The Milky Way is a large spiral galaxy. Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.

What is the oldest thing in the universe
Universe’s oldest known quasar discovered 13 billion light-years away. Astronomers have found the farthest known source of radio emissions in the universe: a galaxy-swallowing supermassive black hole.
Is anything smaller than a photon
nothing is smaller than a photon. It has no matter. we can’t see a photon. It has no matter.
How small is a quark
The data tell us that the radius of the quark is smaller than 43 billion-billionths of a centimetre (0.43 x 10−16 cm).
What is our galaxy called
The Milky Way GalaxyAstronomy > The Milky Way Galaxy. Did you know that our star, the Sun, is just one of hundreds of billions of stars swirling within an enormous cosmic place called the Milky Way Galaxy? The Milky Way is a huge collection of stars, dust and gas.

Can the universe be older than we think
Since around 1997–2003, the problem is believed to have been solved by most cosmologists: modern cosmological measurements lead to a precise estimate of the age of the universe (i.e. time since the Big Bang) of 13.8 billion years, and recent age estimates for the oldest objects are either younger than this, or …
How many galaxies are in space
Several thousand galaxies, each consisting of billions of stars, are in this small view. XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to two trillion galaxies.
What’s bigger than a galaxy
A supercluster is a large group of smaller galaxy clusters or galaxy groups; it is among the largest known structures of the universe.
What is the oldest animal on earth
Seychelles tortoiseA Seychelles tortoise named Jonathan, at 187, recently made it into the Guinness World Records as the oldest known living land animal.
What is the most powerful thing on earth
gamma-ray burstsThese 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.
Does the universe end
The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity).
Which thing is bigger than universe
Cosmos At Least 250x Bigger Than Visible Universe, Say Cosmologists. The universe is much bigger than it looks, according to a study of the latest observations. When we look out into the Universe, the stuff we can see must be close enough for light to have reached us since the Universe began.
What is the smallest thing in the universe
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
What is the smallest galaxy in the universe
Segue 2Scientists at the University of California at Irvine have discovered a galaxy so small that it barely even qualifies as a galaxy. Deemed “Segue 2,” the dwarf galaxy only contains about 1,000 stars and is the least massive galaxy in the known universe, reports Phys.org.
How old is our universe
13.77 billion yearsThe universe is (nearly) 14 billion years old, astronomers confirm. With looming discrepancies about the true age of the universe, scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).
Who created the universe
The earliest cosmological models of the universe were developed by ancient Greek and Indian philosophers and were geocentric, placing Earth at the center. Over the centuries, more precise astronomical observations led Nicolaus Copernicus to develop the heliocentric model with the Sun at the center of the Solar System.
What was before the universe
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
What is outside the universe
Outside the bounds of our universe may lie a “super” universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever. Lying hundreds of billions of light years from us could be other island universes much like our own.
What is a dead galaxy
Galaxies begin to ‘die’ when star formation stops inside them or they start losing material that forms stars. … The galaxy is still forming new stars very rapidly, but since it is also quickly running out of fuel, the remaining gas will be consumed and the galaxy is likely to be dead within a few million years.
