its predicted that by 2046 we will have a fast/efficient way to effectively go faster in space without the use of expensive rocket/nuclear technology. that's in our lifetime and as research shows, we can only go further from here. remember that research effectively doubles when we gain even the slightest of new information. look at the computer chip, what could only process mere numbers back then, can now run simulations of the loving earth itself. today isn't tomorrow, hyperdrive, ftl. it'll happen eventually. be worried about now instead of tomorrow.
