Hello Toby
Thank you for coming by and reading my essay.The point I am making is we have have to think long term and answer questions like:
a)What is the ultimate goal of humanity? As the human population increases should we remain as a one planet species?Clearly the resources will not be adquate to sustain an ever increasing population. Ultimately we will have to reach for the stars.To do so we need to sail the vast expanses of space-time.To do so we need to understand the fundamental properties of space-time and see it as a resource that can be harnessed for the benefit of humanity. Although it might take a long time to fully grasp the fundamentals we might learn a few thingsalong the way that might be of immediate use.
b)Understanding Quantum gravity is not just an intellectual pursuit but also has practical and technological benefits some which we cannot comprehend at the moment no more than a person from the 19th centuary would comprehend how humanity would benefit from the newly formulated unfied theory of electricity and magnetism by Maxell.
