I was looking at the "Where Is Webb" progress web page and noticed that it shows Webb about halfway through the total number of days to the final L2 location but that distance traveled is about 3/4 of the way. And wondered why?

Reminds me of the experiment that if you put a gun in a vice at X height off the ground and you hold a bullet in your hand at the same height, and you fire the gun and at the same time drop the bullet, both bullets hit the ground at the same time.

Are we all not moving at the speed of light relative to a photon or a neutrino?

But yet something has happened. I leave Earth at near the speed of light, my clock ticks one second per second. But when I return, my twin brother is now older than me. So either time slowed for me or sped up for him. But yet both our clocks ticked at one second per second. It could be said that...

So if it NEVER happens to "you" then is it true that it only happens to the observer?

I will edit the post...

Bob, Alice and Ted are all on earth. Bob leaves Earth traveling at .08 light speed for 6 months out then turns around and heads back to earth. Effectively he has been traveling for a total of 1 light year. Ted leaves Earth at the same time as Bob but only travels at .04 the speed of light for 3...

Does this video even make sense? And if so, is it right or wrong?

The The answer is simple. Tight tolerances and proper lubrication.

It's a hard concept to grasp. And then there is the "no edge"... meaning what are we expanding into! The universe is a very strange place indeed!

You're right, I had it backwards. Thought about it after the post!

And if I'm not mistaken, that is the problem with the "bang"...if it happened "everywhere" how could there not be a center? I've been reading a lot of articles that are seriously questioning the "big bang theory"...

The "big bang" suggests that everything came from a single point. If this is true that how can there be no center? And if everywhere is the center, then the universe by definition has to be infinite. And if the universe in infinite, then how did it become that way?

Very interesting in both cases! I can only imagine the laws that might have to be written in the future!

Although we can't technically do this currently, what if we could? What would be a reason to send a person on a mission into the future? If Bob travels at near the speed of light from Earth for let's say 5 years and then returns to see Alice. Alice has, and in fact the entire population of Earth...
