I appreciate this small close community where people show lots of kindness and share happiness! Hello

Are you a bot?

Not answering automatically means "yes".

Let's give him 12 hours.

Thank you for the extra hours Vingey, no I am not a bot. Why do you assume?

No offense, but that 12 hours thing was meant as a joke, since I didn't expect you to reply back lol. There has just been a lot of new users who would make threads about random stuff and leave them unattended once the threads have started to gain responses from the community, so it would only be logical to go with the bot assumption. Anyway, hello!

If you stacked every ruler in the world end to end between the Earth and the Moon, they would all drift away before youcould measure anything at all.

That's really deep, man. Now pass the bong around, please!

Doppler shift in a vacuum depends on the reference frame that you choose and is not a property of the object that exhibits it. This also applies to light wavelengths. Colors are affected by relative motion. Welcome to relativity.

Example:

John: "Why Greg, you're looking particularly blue today!"
Greg: "Thanks dude, but it's not the pandemic. I'm just moving very fast towards you. Like impossibly fast. We must be in a meme or a stupid example someone is writing!"
John: "Ah, now that you've stopped you're back to your normal self. Weird."
Greg: "I wonder if I..."
John: "Yes, you've turned all red now, running away from me like I'm the new plague. What's up with that?"
Greg: "Einstein, man. The world was simple before he went and ruined it all!"

P.S.: Replace blue with green and red with orange if you want Greg to be half the speedy ahole he currently is.

doppler in a vacuum?

While generally linked to sound, because of their initial discovery, dopper shifts can be seen in a variety of wave-type propagations, including electromagnetic waves and gravity waves, which do not need a medium.

linux gaming is like cyberpunk launch they want you to be the beta tester for them

No offense taken, Hello there pal!

I fear for his structural integrity when attempting such a maneuver, even with the power of the ring. Also, he should appear shorter (aka compressed) in his direction of travel (due to Lorentz contraction), which the comic got wrong :P.

...unless the pencil artist was also traveling at a sizable fraction of the speed of light alongside him. In which case it's fine. They flew a helicopter on Mars today, so who's to say what's possible and what's not?

There is no meaning, only the GOGbears!
