Lemaître, based on Hubble's observations, was the first to propose the idea of an expanding universe, leading to the formulation of what is now known as the Big Bang theory. He suggested that the universe began from a "primeval atom," which exploded and has been expanding ever since. This concept challenged the then-prevailing static model of the universe and laid the groundwork for modern cosmology. Lemaître's insights significantly contributed to our understanding of the origins and evolution of the cosmos.
What else can I help you with?
What is an assumption based on observations?
It is an inference :)
What is an idea that is based on many detailed observations?
An idea based on many detailed observations is an empirical theory. This type of theory is grounded in data gathered from systematic and careful observations of the natural world. The strength of an empirical theory lies in its ability to make predictions and be tested through further experimentation.
What must observations avoid?
Observations should avoid being biased, making assumptions, and drawing overly generalized conclusions. It is important for observations to be objective, specific, and based on actual evidence in order to be reliable and useful for analysis.
What are observations tht describe called?
Observations that describe have various names based on the context, such as facts, data, evidence, or findings. They provide information, details, or characteristics about a particular subject or situation.
What is an unproven statement based on observations called?
An unproven statement based on observations is called a hypothesis. It is a proposed explanation for a phenomenon that can be tested through experimentation and further observation. Hypotheses are essential in scientific research as they guide the inquiry process and help in formulating predictions that can be validated or refuted.
Are scientific models based on a set of observations true or false?
It is true that scientific models are based on a set of observations, along with a logical analysis of those observations.
What forms general ideas and rules based on your experiences and observations?
observations
What is a explanation of things or events based on many observations?
An explanation of things or events based on many observations is a theory.
What is the difference between quantitive and qualitive observations?
Quantitative observations are observations that can be precisely measured. Qualitative observations, meanwhile, are subjective observations that are based on the characteristics of what is being observed.
A conclusion based on observations is?
Generalization !
What are primary documents based on?
observations
What is an assumption based on observations?
It is an inference :)
What are scientific inferences based on?
Scientific inferences are based on observations
A scientific law an explanation of things or events based on observations of an explariment?
Is a scientific law an explaination of thing or events based on observations of an explariment
What is weant by qualitative observations and quantitative observations?
quantitative observations can be expressed in numerical terms while quantitative observations are based on your senses - what you can see, hear, smell, etc.
What is An explanation of observations or events based on knowledge gained from many observations and investigations is called an?
A "Theory".
What is observations and data on which a scientific explanation can be based?
No
