Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

If we could accelerate at a constant 1g, flip, and decelerate at a constant 1g, the trip would take ~152 years... from Earth's perspective. If you were onboard, time dilation would make the trip about 10 years.
1g! We have like 6g now!
C'mon billionaires! This is your chance to create a totally unique planet! Get onboard an X rocket and fly your teslas out there! We are all counting on you my friends! All of you! We will need the chip guys, the real estate and building tycoons, the medicine billionaires and everyone in between, all you must go!
Do you mean "c" instead of "g"? I don't think there are a lot of "g" in interplanetary travel.
I mean 'g'. 1g is 9.81m/s^2. c is a speed, not an acceleration. g is acceleration.
Not coincidentally, it's the acceleration you experience from Earth's gravity, but it doesn't have to come from gravity. Astronauts routinely experience 3gs during takeoff from their rocket boosters.
If you were in a rocket that accelerated at a constant 1g it would feel like Earth's gravity, even in space. We don't have any rockets capable of producing 1g for years.
I understand now, thanks.
No, g is a measure of acceleration equal to Earth's gravitational pull at the surface of earth (approx 9.8 meters per second per second). 'c' is the speed of light, you can't accelerate with a speed.
Ok, thanks for the clarification, I clearly misunderstood "g" and how it was used.
