Yes, there are definitely more than a trillion stars in the universe. The estimated number of stars in the observable universe is much larger than a trillion. However, it's important to note that the exact number is still a subject of ongoing scientific research and estimation.
The observable universe is a vast expanse that we can observe from Earth, and it encompasses all the regions of space from which light has had enough time to reach us since the Big Bang, which is estimated to be about 13.8 billion years ago. Within this vast volume, there are billions of galaxies, each containing billions to hundreds of billions of stars.
To give you an idea of the scale, the Milky Way, our own galaxy, is estimated to contain anywhere between 100 billion to 400 billion stars. And considering that there are billions of galaxies in the observable universe, the total number of stars is likely to be much larger than a trillion.
It's worth mentioning that the actual number of stars in the universe could be even greater, as our current estimates are based on the observable universe and do not account for regions beyond what we can currently observe. Furthermore, there may be stars that exist in intergalactic space or are too dim to be detected by our current instruments.
