“Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my luck and instead will spend my life trying to find flaws in this understanding – such is the role of a scientist.” -Brian Schmidt
Imagine you had arbitrarily great technology, limitless energy, and the ability to accelerate as close to the speed of light for as long as you wanted. Would you be able to reach the most distant galaxies, the leftover glow from the Big Bang or anything beyond the limit of what we can see today?
Not only are all of those things off the table, but the farther we travel into the future, the more our presently observable Universe becomes inaccessible. In only a few tens of billions of years, even the cosmic legacy of our creation – the Big Bang – will be inaccessible to us, as well as any galaxies beyond our own at all.
I wrote a script for the Kurzgesagt – In a Nutshell channel on YouTube, and the amazing video above is the wonderful result!
