Could it really happen?

So I've been discussing the ignorance of time travel and how it should never be allowed. But let's talk realistically here... could time travel even exist or be possible? Well in modern times, it is virtually impossible. According to modern theories of time travel, we do not have the resources or knowledge of how to create some sort of device to perform this. One method of time travel is to travel through a black hole. Physicists claim that the amount of energy required to make a black hole is beyond our capabilities. So even though multiple theories exist about the possibilities of time travel, in is unlikely that we will see it happen during our lifetime.
