Which is currently the most supported theory about the future of the universe?
The universe could remain exactly as it is today.
The universe may continue to expand.
Stars could burn out, causing the universe to become dark and cold.
Gravity could pull galaxies back together, causing a reverse of the big bang.
Currently, the most supported theory about the future of the universe is the idea that the universe will continue to expand. This theory is based on the observed acceleration of the universe's expansion, which suggests the presence of dark energy. Dark energy is thought to be responsible for this accelerated expansion and is predicted to result in the universe's continued expansion, potentially leading to a future where galaxies become even more distant from each other and eventually becoming isolated islands of stars. However, it is important to note that our understanding of the universe is constantly evolving, and future discoveries may lead to new theories or modifications to existing ones.
but what is the answer
The answer is that the most supported theory about the future of the universe is the idea that the universe will continue to expand.
Amoebas are unicellular. The single cell splits in half to form two new cells. A student claims amoebas are alive. Is the student correct?(1 point)
Responses
The student is correct; amoebas are alive because they become multicellular.
The student is correct; amoebas are alive because they become multicellular.
The student is not correct; amoebas are not alive because they are only made of one cell.
The student is not correct; amoebas are not alive because they are only made of one cell.
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.
The student is correct; amoebas are probably alive because they have reproductive capabilities and create offspring through reproduction.
The student is not correct; amoebas are not alive because two different amoebas are not contributing together to make a new offspring.
The student is correct; amoebas are alive because they have reproductive capabilities and create offspring through reproduction.
In 1998, scientists discovered that the expansion of the universe has been accelerating.
What force is causing this phenomena?
dark energy
Hubble’s law
the Doppler effect
background radiation
The force causing the acceleration of the expansion of the universe is believed to be dark energy.
In which order did the events forming our solar system occur?
The solar nebula became hot and dense pulling in more gas.This flattened into a rotating disk. It spun faster and faster, forming the Sun.
Gas was pulled toward the center, forming the Sun. Gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster.
Gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster. Gas was pulled toward the center, forming the Sun.
The solar nebula spun faster and faster and flattened into a rotating disk. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.
The correct order of events forming our solar system is:
1. Gas flattened into a rotating disk and became hot and dense, forming a solar nebula that spun faster and faster.
2. Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun.
Which event led to the formation of our solar system?
A galaxy broke apart.
A massive star exploded.
A solar nebula collapsed.
Dark matter materialized.
The event that led to the formation of our solar system is the collapse of a solar nebula.
Which statement accurately describes the outer planets?
Pluto is one of the outer planets.
The outer planets are also called rocky planets.
The outer planets have thin atmospheres.
The outer planets have a high gravity due to their large size.
The statement that accurately describes the outer planets is: "The outer planets have a high gravity due to their large size."
Which statement accurately describes how the understanding of the Doppler effect is applied to the study of galaxies?
It was used by Hubble to measure the velocities of galaxies.
It was used to monitor galaxy motion through changes in sound waves.
It indicates a galaxy moving toward Earth through red shift.
It indicates a galaxy moving away from Earth through blue shift.
The statement that accurately describes how the understanding of the Doppler effect is applied to the study of galaxies is: "It indicates a galaxy moving away from Earth through blue shift."
What would most likely cause the future acceleration of the expansion of the universe?
radiation from the Sun
the existence of background radiation
the continued existence of dark energy
light shifts identified by the Doppler effect
The most likely cause of the future acceleration of the expansion of the universe is the continued existence of dark energy.
Which is one piece of information that astronomers use to calculate the age of the universe?
dark energy
the age of rocks on Earth
the current motion of inner planets
patterns of background radiation
One piece of information that astronomers use to calculate the age of the universe is the patterns of background radiation.
Which statement accurately describes planetesimals?
They are the origins of planets.
They formed from ice and rocks.
They were created during the big bang.
They contain 98% of matter in the solar system.
