steady state theory
this theory proposes that the universe is unchanging in time and is uniform in space
end of unified forces
what era is defined by this characteristic of the universe : this is where electromagnetic and weak nuclear forces separate.
nucleosynthesis
what era is defined by this characteristic of the universe : this is where helium, deuterium and a few other elements form
electromagnetic force
this is a long ranged force that binds atom
bubble universe
Proposal that our universe is just a bubble in a much larger "multiverse", this is our own version of stars and galaxies...
leucippus and democritus
they beleieved in an atomic universe.
aristotle and ptolemy
who proposed a geocentric universe?
isaac newton, 1687
he describes the universe as static, stead state and infinite. matter is on a large scale, uniformly distributed.
cosmology
this is the study of the universe
cosmologists
they study the the structure and the changes of the present universe
true
the universe includes all the space and time
unvierse
the ___ contains all the star systems, galaxies, gas, and dust, plus all the matter and energy that exists now
religious cosmology
this explains the origin, history and evolution of the universe based on the creation mythology of a specific tradition
true
there are 6 theories of creation, however- 5 are only accepted by science.
big bang theory
the universe is believed to have started from a great explosion or expansion.
false, tiny point.
in the big bang theory, all matter was crammed into a big point called a singularity.
big bang theory
this theory was proven by the cmb, galaxies moving and nucleosynthesis and is the most accepted.
steady state theory
has no begining or end in time. unchanging evidences.
inflation theory
according to this theory, the size of the universe drastically increased.
string theory
according to this theory, the fundamental building block is a string. the strings can be closed as in loop, open as in a single strand.
m-theory or multiverse theory
this states that there are multiple universes, and all of existence (energy, matter) is found in the multiverse.
m-theory
this says that each multiverse has its own laws of physics
m-theory
This theory considers 11 space-time dimensions.
singularity
this an intensely hot and infinitely dense point, a few milimeters wide.
supercharged black hole
the singularity has been described similarly to a what?
13.7 billion years ago
how long ago did the big bang occur?
big bang, plank time, end of grand unified theory, inflation, end of unified forces, heavy particle, light particle, nucleosynthesis, recombination, galaxy formation.
name the ten components of the big bang theory timeline.
bigbang
what era is defined by this characteristic of the universe : infinitely small, infinitely dense, and infinitely hot "something as singularity"
plank time
what era is defined by this characteristic of the universe : earliest known time described by modern physics. this is where gravity separates and there is unified forces.
Grand Unified Theory
what does GUT stand for?
Grand Unified Theory (GUT)
A theory that unifies three of the four fundamental forces—the strong force, the weak force, and the electromagnetic force (but not gravity)—in a single model.
inflation
what era is defined by this characteristic of the universe : in where the size of universe drastically increased
heavy particle
what era is defined by this characteristic of the universe : this is where proton and neutron come in full swing
light particle
what era is defined by this characteristic of the universe : this is where electron and positron form
recombination
what era is defined by this characteristic of the universe : this is where matter and radiation separate
galaxy formation
what era is defined by this characteristic of the universe : this is where galaxies and other large structures form in the universe
strong force, electromagnetic force, weak force, gravitational force
give me the four fundamental forces of the bigbang theory
strong force
this is a short ranged (10-13cm) attractive force that binds nucleus
false, 10-13cm
a strong force is short ranged, about 8-9cm.
weak force
Short-ranged force present in radioactive decay
gravitational force
a weak, long-ranged, and attractive force which binds the solar system. this is also the first to separate from the forces.
true
one limitation of the big bang theory is related to flatness. it says that the geometry of the universe is almost flat.
false, its curved.
the inflation theory proposed a theory to fix the problem of flatness in the big bang theory. it says the surface we see is slightly wavy, and would appear flat even though its a sphere.
monopole
in bigbang, the _____ predicted the heavy production of heavy stable magnetic _____ however no magnetic _____ have been observed.
true
a problem of monopoles in the bigbang theory is that it has predicted a heavy production of stable magnetic monopoles, however there is no magnetic poles observed.
inflationary epoch
the inflation theory, monopoles allow the existence of the monopoles as long as they were produced prior what epoch?
horizon
what problem in the bigbang theory says that the distant regions in opposite directions of the sky are so far that they could never have been in casual contact with each other.
exponential expansion
inflation theory proposed a solution for the problem of the horizon, it assumes a ________, which means that the distant regions were actually more closer to each other prior inflation
m-theory
this theory says that our universe is just one of many bubbles. this suggests that our universe, with all its hundred galaxies may not be the only one.
parallel universe or alternate reality
this says that many worlds which exist in a parallel universe at the same space and time as our own. this is basically another copy of our universe.
membranes / extra dimension
this is a book-like page dimension, with its own physics and etc.
many worlds / quantum mechanics
this is related with parallel, different realities.
true
the strings in string theory are free to vibrate at different modes.
big crunch
the current expansion of the Universe ultimately slows, stops and then reverses to begin contracting.
scaler field
this makes gravity less with negative pressure.
cosmic inflation
the theory that the universe experienced a sudden and brief burst in size immediately after the Big Bang
branes
are two and 5 dimensional objects to which strings can attach one or both their ends
genesis
from what narrative did one of the books of the hebrew bible and the christian old testament describes how god separated light from darkness.
rigveda
what is the hindu text that describes the universe as an oscillating universe in which a somic egg contains the whole universe and expands out of a single concentrated point.
brahmanda
this is what you call the cosmic egg
bindu
this is the expanded single concentrated point
anaxagoras
he is the one who believed in a primodrial universe and explain the original state of the cosmo was primordial mixture of all its ingredients. this is where a whirling motion sifted all the ingredients.
atomic universe
this says that the universe was composed of very small, indiviisble and indesructivle atoms composed of different arrangements of eternal atoms.
