Another point that the lecturer uses to cast doubt on the reading is privatization of space travel will not accelerate the rate of scientific discoveries. The lecturer claims that commercial space will delay discovering and innovation and as results, serious space research may suffer. However, the reading only states that privatization of space travel will accelerate the rate at which important scientific discoveries occur.
Finally, the professor stated that, on the contrary of the reading, it is impossible that the space travel will give the whole taxpaying for public. In other words, the private space tourism will pay huge taxes for like billion dollars to build space stations and so on. In fact, all taxes will pay more to support the vacation of space tourists. This contradicts the final idea of the reading passage because it only says that the costs are paid for by the whole taxpaying public.
