As far as we can tell, there is no edge to the universe . Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. ... The flatness of the universe means that the geometry of spacetime is not curved or warped on the cosmic scale.
How long would it take to reach the edge of the universe?
It's Space Day, but traveling the vast entity that is space would take far longer than a single day. The nearest galaxy: 749,000,000 (that's 749 million) years. The end of the known universe: 225,000,000,000,000 years (that's 225 trillion) years .
Can we reach the edge of the universe?
Unfortunately, since universe is technically expanding faster than the speed of light (due to the expansion of space between matter), it is theoretically impossible to ever reach the “edge” of the universe , since it will always be moving away faster than we could ever move towards it!
Can scientists see the edge of the universe?
There is no evidence that the universe has an edge . The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see – more than 10 billion light-years, or about 6 billion trillion miles.
Does the universe have an 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).
What is at the end of space?
Many think it's likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. ... Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Is the space endless?
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. You might think this means the universe is infinite.
What's at the edge of the universe?
The Universe has many edges: the edge of transparency, the edge of stars and galaxies , the edge of neutral atoms, and the edge of our cosmic horizon
Are galaxies really moving away from us or is space just expanding?
The galaxies outside of our own are moving away from us , and the ones that are farthest away are moving the fastest. ... However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else.
Do wormholes exist?
Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence. Some of these “primordial wormholes” may still be around today. ... They may even help us understand some of the deepest cosmic mysteries, such as whether our universe is the only one.
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 inside a black hole?
HOST PADI BOYD: While they may seem like a hole in the sky because they don't produce light, a black hole is not empty, It's actually a lot of matter condensed into a single point. This point is known as a singularity .
Does space have a smell?
In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique ,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.
Has any astronaut been lost in space?
We've lost only 18 people in space —including 14 NASA astronauts—since humankind first took to strapping ourselves to rockets. ... Today's astronauts travel to space by way of the Russian Soyuz, then spend a few months on the International Space Station.
Does time ever end?
The simple answer is, “ Yes, it is possible to stop time . All you need to do is travel at light speed.” ... We know that an object, or a light beam's, speed measures the distance traversed over time.
Can the universe be infinite?
If the universe is infinite, it has always been infinite . At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. Imagine a large flat rubber sheet with sand placed as closely together as possible on the sheet.
