Is the universe in the same shape of the earth : a sphere ?

Question

It was long believed that the earth was flat till it was proved otherwise. Could this be the same case with the universe ?

It is not impossible... Everyone thought Christoper Columbus was going to fall off the world, but guess not...

Answer 1

There may be two answers to this question.
First;The universe is spherical.expanding from a single point.
It is definitely finite and will someday become extinct.
Seems like a big ball!!

Second;Time acts as just more than an arrow barreling inexorably in one direction.
Every entity in the universe has a zero time point.
You,me and an atom.
In any direction we look into the past.
This would imply a two dimensional expanding sphere.
This would not be much fun!
We know the universe works.It incorporates a sort of holographic feature that allows entities to interact,seemingly in a solid sphere.
Two people in a room see each other as they were in the past.
Maybe three-hundred millionths of a second ago.
Because our reaction time is about one-tenth of a second,we have no awareness of this time lag.
To be significant to two people they would have to be about 18,000 miles apart.They would be absolutely unaware of each other.
This holographic trick of the universe extends to fundamental particles[The uncertainty principle] and to celestial bodies,stars,galaxies and large structures.
Philosophers may want to jump in here to try and hone a comprehensive configuration to this phenomenon.
Well I hope I did not confuse you to much. I am going to have sit down and figure out just what I said.

Answer 2

There are actually 3 theories!
1. The universe is expanding, and, if there is enough MASS within, will reach a stage where gravitation and expansion forces will equalise, then the gravity force will take over and the universe will start collapsing on itself to the big crunch. In that case, the most accepted shape is the SKIN of a balloon or sphere (no "inside", no "outside", no "center"). The balloon inflates and the galaxies all move apart. During the collapse, the sphere will "deflate" until there is nothing lef (the big crunch).
This universe has NO boundaries, (there is no "Edge" on a sphere), but it is FINITE.
2. The universe is expanding, and there is not enough MASS (matter) within it. It will continue to expand forever. Its shape is, mathematically speaking, one of a saddle (as said above). In this case, it has no boundaries, but still finite.
3. The universe is expanding, and there is EXACTLY the right amount on MASS in it. The universe will continue to expand forever, but will also flatten, like a sheet of paper. It MIGHT have boundaries, but will be INFINITE.
Choose the one you want, it does not really matter: we can only get the answer in more or less 16 billion years!
Note: there is another one! According to the developments of the super-string theory (Steven Hawkins and collegues), the universe could be the shape of a downuts, finite in volume, but with no boundaries...
Again, wait and see!

Answer 3

For some odd reason the answers you are receiving are nonsensical. The universe started from a point and expanded. A spherical shape is expected when something started from one spot. Here's where things get complicated. The universe is expanding outward from literally everywhere. There seems to be no central focal point which suggests a spherical expansion. But it is still thought that the universe must expand in the shape of a bubble even though radioactive evidence suggests no middle can be found. Scientists are now caught in the conundrum of basic physics (a spherical universe) and contradictory proof. I will definitely stake my reputation that the universe is definitely NOT flat. It is an expanding entity which is hard to grasp for the layman and the scientist alike.

Answer 4

They say the universe is endless, so no shape. I believe it is circular...making it seem endless but in reality if we keep going one way we will eventually reach the starting point. The question is: what is after the Universe. Who knows, we could be living in an atom (which mimics the model of the universe), and outside of it is a totally different world. Something like the end sequence of Men in black.

Answer 5

Actually, no. Since Einstien's Theory of General Relativity, most scientists believe the universe to be saddle shaped. However, the universe is so large we can only prove this using high end calculations.

Answer 6

never. as a results of fact the earth is, greater or less, a 3-dimensional sphere. The universe isn't. yet perchance there's a analogy, and that i think of that is what you have in recommendations. Earth's floor is finite and easily curved. The universe (area) could be finite and easily curved too. it fairly is a answer of Einstein's concept of prevalent relativity. yet in undemanding terms one among many. So enable's assume which you coulf you flow right now long adequate and you may result the place you have been. if so, this could recommend which you have discovered an significant fact concerning to the geometry and topology (shape) of area. The geometry could nicely be a) open, b) flat, or c) closed. If c) than you are able to commute in circles "around" the universe", as a results of fact area is finite and easily curved as pronounced above. like the exterior of earth is finite and easily curved, for that reason in concept you may desire to stroll/swim around. If a) or b) area could be endless and negatively curved or no longer curved in any respect. in accordance the main recent measurements area is flat or only approximately flat. for that reason we won't be able to tell fairly. perchance it fairly is "domestically" flat (i.e. the finished observable universe) yet no longer globally (previous our cosmic horizon). BTW: whether c) the universe seems to be so huge which you would be able to't commute around the universe interior the universe's lifetime, even easy won't be able to. even though: a), b), and c) are in undemanding terms actual if the topology (shape) is hassle-free. even though it desire to no longer be. We only won't be able to tell yet in addition there is learn happening approximately this. In a greater complicated topology, e.g. a torus universe or one in all those "reflect corridor", the geometry could desire to be open or flat and you may desire to commute in circles in spite of the actual undeniable fact that. unusual, yet available. you may make it even somewhat fastly if the topology is compoact and small. it is not likely, i think of, yet no longer refuted yet.

Answer 7

The Universe is Infinite and hence it is beyond shape
It has neither shape nor size, it extends beyond the limits of size and shape which are properties of finite objects such as the Earth.
The Universe is also neither flat nor spherical. It being infinite would extend beyond both the types

Answer 8

Universe is endless till now and when someone will discover its shape i will surely inform u.

Good luck

Answer 9

the universe is supposively neverending, which is difficult to explain but you need to look at it as a 3 dimensional object that has unlimited size with really no shape

Answer 10

the universe is not a shape, it is a vast, endless space
and the earth is not a perfect sphere it is a distorted oval shape
