Depending on where we look, the universe is expanding at different rates. Now, scientists using the James Webb and Hubble space telescopes have confirmed that the observation is not down to a measurement error.

In the 21st century, multiple methods have been used to determine the Hubble constant. “Late universe” measurements using calibrated distance ladder techniques have converged on a value of approximately 73 (km/s)/Mpc. Since 2000, “early universe” techniques based on measurements of the cosmic microwave background have become available, and these agree on a value near 67.7 (km/s)/Mpc. (…)

It’s simple, imagine you’ve got two smart friends that both have an opinion about a TV show you didn’t watch - you can’t tell who is right but the fact they disagree suggests they might be wrong when they say you can’t have flying cars and time travel.

Can someone give me the spark notes I started reading but I’ll never get through that or probably even understand all of it
