Are there infinite stars

For example, in other worlds I have won the Nobel Peace Prize, the word 'fish' is a curse word, George Bush is a serial killer. The universe may be infinite, but we can only see a finite section of it due to the finite speed of light. We can only see those parts from which light has had time to reach us since the beginning of the universe - which means we can in theory see a spherical universe with radius of about 47 billion light years. If I gave you some time to think about that I'm sure that you would come up with the following conclusion - "that means that the universe must have expanded faster than the speed of light at some point", which appears to violate special relativity.

In fact that is what is thought to have happened, during a period called "inflation", and it does not violate special relativity since it is not a spatial motion, but the expansion of space itself. Back to your question: if the universe is infinite beyond our horizon, is there an infinite number of "you"s out there? I wonder if you have covered probabilities in school?

If you haven't let me know if you don't understand the following. If there is a finite probability of something happening ie. So there would be an infinite number of galaxies and planets in an infinite universe. If however there is an infinitesimal probability of something happening, then in an infinite universe there would only be a finite number for example 1 of those things.

I would argue that the probability of creating a specific person with a specific genetic make-up and way of thinking may only be infinitesimal it depends on how complex you think humans are - therefore there is only one of you! People also use this argument against the idea that there must be ET life out there in such a big universe - if the probability of life forming is infinitesimal then there could only be one life bearing planet.

I personally think that it's more likely that life forms with a finite probability than it is that a specific person forms. See an interesting article by an astronomer, Max Tegmark on this here.

It was written for a scientific audience but seems fairly readable. Karen was a graduate student at Cornell from She went on to work as a researcher in galaxy redshift surveys at Harvard University, and is now on the Faculty at the University of Portsmouth back in her home country of the UK. Her research lately has focused on using the morphology of galaxies to give clues to their formation and evolution. She is the Project Scientist for the Galaxy Zoo project.

If the universe is infinite does that mean there is an infinite number of "me"s? Similar Questions that might Interest You If there are infinity universes, will every thing that is possible happen? Intermediate Does inflation allow for an infinite number of universes? The Hubble Deep Field image was taken at optical wavelengths and there is now some evidence that a lot of early star formation was hidden by thick dust clouds. Dust clouds block the stars from view and convert their light into infrared radiation, making them invisible to the HST.

But Herschel could peer into this previously hidden Universe at infrared wavelengths, revealing many more stars then ever seen before. Soon Gaia will launch, which will study one thousand million stars in our Milky Way.

It will build on the legacy of the Hipparchus mission, which pinpointed the positions of more than one hundred thousand stars to high precision, and more than one million stars to lesser precision. Gaia will monitor each of its one billion target stars 70 times during a five-year period, precisely charting their positions, distances, movements, and changes in brightness.

Combined, these measurements will build an unprecedented picture of the structure and evolution of our Galaxy.

Thanks to missions like these, we are one step closer to providing a more reliable estimate to that question asked so often: "How many stars are there in the Universe?

You have already liked this page, you can only like it once! Hipparcos mapped millions of stars in our galaxy, but how many more are there? Gaia mapping the stars of the Milky Way In , an image from the Hubble Space Telescope HST suggested that star formation had reached a peak at roughly seven thousand million years ago. Like in these video games in which mountains keep appearing as far as you walk.

Theoretically yes, there can be infinitely many stars. Since this space you're talking about is better described by general relativity and Einstein's field equations. One of its solutions describes the universe as being spatially infinite. You can check out Olbers' paradox , also known as dark night sky paradox. In short, it argues that the universe can't be a static one ie. This would mean, that we should see the light of all infinite stars at all times, which is definitely not the case if you go out at night and look up.

There is an uncountable amount of stars from our perspective, but space does have a limit of size which is the distance which subatomic particle and matter as traveled since the big bang and with that limit of stars.

Although stars die and form beyond our ability to count so observably we can never have an exact count of stars at anytime as well. I would bet on answer B because The universe does have a total mass of about 25 billion galaxies. We can mathematically calculate the mass of our universe. Sign up to join this community.
