Just a thought - does the universe have the equal of a refractive index so to speak, to measure where stars are, due to gravity curving spacetime.
thanks
thanks

jackcr said:I heard that at the bottom of the black hole there is only light, what would the light look like? Would it just be like light say from a bulb?
jackcr said:Wow, so if it was not impossible, we could theoretically need a whole new set of laws of physics. Thats crazy. So even information cannot escape? What would you define as information?
Scientists use a variety of techniques, such as measuring the star's distance from Earth through parallax, analyzing its spectral characteristics, and using mathematical models to calculate its position in the night sky.
Yes, stars can move and change their location due to various factors such as their own motion, gravitational interactions with other celestial bodies, and the expansion of the universe.
No, stars have specific locations in the sky based on their position within our galaxy and their relative distance from Earth. However, their locations may appear random due to the Earth's rotation and our changing perspective from different locations on the planet.
Scientists use a variety of naming systems, including Greek letters, Bayer designations, and catalog numbers, to identify and classify stars based on their location, brightness, and other characteristics.
Yes, scientists can use similar techniques as those used for stars in our own galaxy to determine the location of stars in other galaxies. However, due to the vast distances involved, this process is more complex and challenging.
