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.

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

What is the oldest animal on earth

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.
