The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the

is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
What is beyond the universe?
Nearby, the stars and galaxies we see look very much like our own. In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
How big is the universe in miles?
The observable universe is approximately 5.4×1023 miles in diameter.
Is the universe infinite?
If the universe is perfectly geometrically flat, then it can be infinite. If it’s curved, like Earth’s surface, then it has finite volume. Current observations and measurements of the curvature of the universe indicate that it is almost perfectly flat.
How big is the known universe?
46.508 billion light years.
Will the universe end?
Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases. Slowly, stars will fizzle out, turning night skies black.
What’s on the other side of space?
If space is infinite, there is nothing on the other side. If space is finite because it has been bent around upon itself because of gravity, then again there is nothing on the other side of it because there is no seam. It looks like the surface of a smooth ball which represents a piece of flat paper bent upon itself.
How many universes are there?
There are still some scientists who would say, hogwash. The only meaningful answer to the question of how many universes there are is one, only one universe.
Can we look back in time?
The time it takes for light from objects in space to reach Earth means that when we look at planets, stars and galaxies, we’re actually peering back in time. When we look up at the stars, we are looking back in time. The light entering our eyes from these distant objects set off years, decades or millennia earlier.
What is bigger than the universe?
The universe is much bigger than it looks, according to a study of the latest observations.
How cold is space?
Far outside our solar system and out past the distant reachers of our galaxy—in the vast nothingness of space—the distance between gas and dust particles grows, limiting their ability to transfer heat. Temperatures in these vacuous regions can plummet to about -455 degrees Fahrenheit (2.7 kelvin).
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.
Who created the universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
What is the biggest thing in the universe?
The largest known ‘object’ in the Universe is the Hercules-Corona Borealis Great Wall. This is a ‘galactic filament’, a vast cluster of galaxies bound together by gravity, and it’s estimated to be about 10 billion light-years across!.
How many planets are in the universe?
For those of you who like to see gigantic numbers written out in full, around 10,000,000,000,000,000,000,000,000 planets in our observable Universe, and that’s only counting planets that are orbiting stars.
Why is space so big?
Why is the Universe so Big? The Universe is so big because it is constantly expanding, and it does so at a speed that even exceeds the speed of light. Space itself is actually growing, and this is going on for around 14 billion years or so.
How long till the universe ends?
22 billion years in the future is the earliest possible end of the Universe in the Big Rip scenario, assuming a model of dark energy with w = −1.5. False vacuum decay may occur in 20 to 30 billion years if Higgs boson field is metastable.
What happens when you reach the end of space?
It will expand forever; the galaxies within groups and clusters will merge together to form a giant super-galaxy; the individual super-galaxies will accelerate away from one another; the stars will all die or get sucked into supermassive black holes; and then the stellar corpses will get ejected while the black holes May 6, 2020.
Is time Travelling possible?
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
Can you see the other side of a black hole?
Such an observation might seem not just difficult but outright impossible, given black holes famously eat up any light that goes near them. But the new study used an unusual effect where light “echoes” around the black hole, such that scientists can see it from the other side.
Do wormholes exist?
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Theoretically, a wormhole might connect extremely long distances such as a billion light years, or short distances such as a few meters, or different points in time, or even different universes.
Will a black hole come to earth?
Thankfully, black hole collisions are likely rare. In the most “optimistic” scenario — optimistic by the scientists’ standards, that is, so populating the galaxy with the maximum number of black holes — there might be one collision or so every billion years, according to the paper’s calculations.
