>>28569From what I understand, high-speed travel does slow the passage of time RELATIVELY. So from the relative perspective of the photon, a journey of billions of light years is instantaneous. But an observer on Earth, traveling much slower than the speed of light, would observe the photon taking one year to travel one light year.
The time dilation caused by the earth's gravity is not even remotely powerful enough to make it so the earth is only ~6,000 years old while the rest of the universe is nearly 14 billion.
>Again this a PhD astrophysicist.Again, that means nothing. He is a PhD astrophysicist who starts with the assumption that the universe is 6,000 years old and looks for evidence to support it. Meanwhile respectable PhD astrophysicists posit the universe is billions of years old based on observable evidence, look for more evidence to confirm or deny such an age, and find overwhelming evidence supporting it.
