Space stuff is cool, and I love watching science-y videos on YouTube about how space, time, gravity etc work.

Often times people don’t know WHAT they are though.

Like WHY does gravity warp things and attract things? No one knows.

But recently Stephen Wolfram developed a new model of what our universe runs on, and it looks pretty damn convincing:

The basics are:
– Our universe is just a blob of connections, the configuration of those connections form matter or space.
– Space and matter aren’t different things, they are the same.
– The increase in amount of connections is time.
– The curve of those connections on a hypergraph are gravity.
– The basic rule of the universe is probably super duper simple, like A –> B.
– A computer needed to run this universe would roughly need to have a speed of 10^400
– Since we are part of the system, there’s actually no way to know for sure what’s outside the system.

So while it doesn’t answer every question, it’s the first time I’ve seen solid evidence on how time, light, and gravity work.

It’s also cool to note that we could technically create a full universe like this with nearly a single line of code on a computer.

After watching the podcast (4.5 hours long) you can understand this chart much better:

I’m not sure it will have a day-to-day impact on anyone right away except physicists….but this is like going from thinking the Earth is flat, to realizing it’s round and orbits the sun. Pretty cool some dude just “invented” this…very inspiring and cool!
