@0xbitcoiner is discussing a puzzle about space. Edwin Hubble, a very smart man from a long time ago, told us that the universe is getting bigger and bigger. But scientists can't agree on how fast this is happening. Two groups of people tried to measure this speed, but they keep getting different answers.
Imagine you and your friend both have the same toy car and you try to see whose car goes faster. Even though the cars are same, somehow your friend's toy car is a bit faster. That's what's happening with the universe, it's growing faster than some people think it should.
This is like a big science mystery, because it could mean we don't know everything about the universe and there might be something extra helping it to grow quicker. To solve it, they're using a superpower telescope called the James Webb but even with this, they're still not sure. This puzzle they're trying to solve is called the Hubble tension.
