Measure the distance from Earth to nearby stars.
One scientist who changed how we view the universe is Albert Einstein. His theories of relativity revolutionized our understanding of space, time, and gravity, and laid the groundwork for modern astrophysics. Einstein's work also led to the development of technologies like GPS that rely on principles of his theories.
Albert Einstein wanted to become a scientist from a young age, showing an early interest in math and physics. He pursued this passion throughout his education and eventually became one of the most renowned physicists in history.
Current scientific meaning of the word universe, is that it includes everything. So there is only one universe - The Universe However the new idea of String Theory is starting to suggest that there may be more than one universe, and so the meaning of the work universe may change in the future. The scientist Brian Greene is one of the leading physicist working on this theory. Science-teacher
One notable instance of a scientist being wrong is the case of Albert Einstein's cosmological constant. Initially introduced to support a static universe, Einstein later referred to it as his "greatest blunder" after the discovery of the expanding universe. This example illustrates how scientific understanding evolves and how theories can be revised or discarded in light of new evidence. It underscores the importance of skepticism and adaptability in scientific inquiry.
Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.
Scientist speculate there may be theoretically, but there is no evidence that there is any universe other than this one.
Aristotle and Ptolemy - pick one.
Georges Lemaître, a Belgian physicist and Catholic priest, was one of the first to propose a computational estimate for the age of the universe. In 1927, he suggested that the universe originated from a "primeval atom" at a specific point in time, although his value for the age of the universe was later revised.
One method is Carbon-14 Dating.
No.
yes, he made the principia, and he is one of the most important contributors to our understanding of how the universe works.
The age of the Universe is calculated based on several methods; one that is fairly easy to understand is the expansion of the Universe. If you extrapolate the expansive movement of the galaxies into the past, you get to a point where they were very close together. The time when this should have happened gives you a general idea of the age of the Universe - assuming that the speed of expansion didn't change. (This assumption isn't entirely accurate, though.)The age of the Universe is calculated based on several methods; one that is fairly easy to understand is the expansion of the Universe.

One method was to determine the age of the oldest stars. Our estimates were around 20 billion years for these. Another was to calculate backwards from the expansion rate, which gave us a value of about 12 billion years. These two disparate numbers were ultimately resolved by very precise measurements made by the COBE satellite, and further enhanced by the subsequent WMAP satellite. We now know the age of our universe to be about 13.8 billion years.

The Sun was formed about 4.57 billion years ago whereas the universe is 13.75 ±0.17 billion years old at current best guess. The sun is about one third the age of the universe.
