If you’ve ever wanted to know how big/old/whatever the universe is … now we know. So, the answers to questions that have been plaguing scientists (and the occasional quiz show) are as follows:
- 13.7 billion years old (accurate to 1%)
- 73% dark energy, 23% cold dark matter, 4% atoms
- Expanding at 71 km/sec/Mpc (accurate to 5%)
- Expand Forever
Now we know. Man … we (i.e. that which you and I actually see in this universe) are only 4% of what’s there … ponder that the next time you encounter some self-important person who thinks the world of themselves, their beliefs, or their causes …
… it’ll help you put them in perspective.
