[R] limit to p-value using t.test()

Hello, I am using t-test to check if the difference between two poulations is significant. I have a large N=20,000, 10,000 in each population. I compare a few different poulations with eachother and though I get different t-scores, I get the same p-value of 10^-16 which seems like the limit for
