1- How did the space was created?
2- Why it still growing?
3- How long or big is the space?
4-There are other worlds like the Earth?
5- Which thing existed before the creation of the space?
Subtopics:
-Galaxies
-Stars
-Wormholes
I'm so interested in this topic because, I think a lot of us have many douds about the space. I like to watch the sky since I was a child.
I want to know more about the space and its components and I think is a very interesting topic.
1.- How did the space was created?
Well scientists has a thory that the space was created by other space similar like this but rather that that space grow it started to compress, then that space became an atom and that atom blew up creating our space.
-Galaxies: the galaxies are a part of the space that are conformed by stars and planets, our space has millios of galaxies.
-Stars: many of the stars are death planets or parts of planets that stay in the space, the stars are rocks that are far of the earth.
-Wormholes: Is a pathway from one part of space and time to another but cientists think that this can't be true, they think that if you enter inside of a wormhole you will be destroyed (literally you blow up).
In 1935, physicists Albert Eunstein and Nathan Rosen used the theory of general relativity to propose the existence of "bridges" through space-time. These paths, called Einstein-Rosen bridges or wormholes, connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance.
Wormholes contain two mouths, with a throat connecting the two. The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require.
If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travelers through space.
But I think that the theory of Einstein isn't real I think that If somthing enter to a wormhole that object will be crushed and then destroyed bye the gravity that is higher than the gravity of the earth
STARS
Star is ball of hydrogen and helium with enough mass that it can sustain nuclear fusion at its core, they can come in different sizes and colors.
An example of a star is our sun.
75% of the matter in the Universe is hydrogen and 23% is helium; these are the amounts left over from the Big Bang. These elements exist in large stable clouds of cold molecular gas. At some point a gravitational disturbance, like a supernova explosion or a galaxy collision will cause a cloud of gas to collapse, beginning the process of star formation.
The protostar at the heart of the cloud heats up from the gravitational collapse of all the hydrogen and helium, and over the course of about 100,000 years, it gets hotter and hotter becoming a T Tauri star. Finally after about 100 million years of collapse, temperatures and pressures at its core become sufficient that nuclear fusion can ignite. From this point on, the object is a star.
Galaxies
Galaxies are huge collections of stars, dust and gas. They contain many stars . In the space exists a lot of galaxies.
Galaxies come in many different sizes and shapes
Spiral Galaxies
Spiral galaxies get their name from the shape of their disks. In a spiral galaxy, the stars are gathered in spiral arms that spread outward from the galaxy's center.
Spiral galaxys are divided into three types: Sa, Sb and Sc.
Spiral galaxies have a lot of gas and newly forming stars.
Elliptical Galaxies
Elliptical galaxies are shaped like ellipses. They are divided into eight types:
E0 ellipticals are nearly circular
E7s are very stretched out.
Elliptical galaxies are made up of old stars, and do not have much gas.
Elliptical galaxies also come in many sizes. T
Irregular Galaxies
Irregular galaxies have no particular shape. They are the smallest galaxies.
Irregular galaxies have a lot of star formation.
They are two small galaxies which orbit around our own Milky Way Galaxy.
About 20% of all galaxies are irregulars.
But I think that the theory of Einstein isn't real I think that If somthing enter to a wormhole that object will be crushed and then destroyed bye the gravity that is higher than the gravity of the earth
