Quicker to walk

If we cannot have a food replicator, how about teleportation? Sadly a group of MPhys students at the University of Leicester have severe doubts about the viability of this transportation method. They note that every human that is teleported will need to be represented in transferable data. This would be a mix of physical DNA and genomic data coupled with the information contained in the travellers brain. The students estimate the total information content to be around 2.6 x 10⁴² bits. Using a teleportation bandwidth of 29.5 to 30 GHz, the students calculated that the data transfer would require up to 4.85 x 10¹⁵ years. The universe is thought to only be around 14 billion years old.
