Supposing a man named Bob falls into a black hole, an instant of Bob's perceived time would be a nearly infinite amount of time to the rest of the universe due to relativity and the effects it has in and near black holes. Okay sure, but we also know (to my knowledge) that black holes "evaporate"...

Okay. I think I'm beginning to comprehend why the answer would be no. Thank you all! People like you guys are why this site is so fantastic!

Let's imagine say, a spaceship is going through space at 99% the speed of light. Relativity says (to my understanding) that as the spaceship increases in speed it's mass will increase and it shall also get slightly shorter. Let's assume that energy isn't a problem, should the spaceship continue...

Whoa! I had no idea Wolframalpha could do that! Thank you!

Hey Guys! I've been doing a few equations in regards to planetary escape velocity and gravitational force. The below links have the escape velocity of listed planet on the left side of the board, the gravitational force between the Sun and given planet on the right side. In the middle of the...

I found the problem! I needed to convert the radius of Saturn to meters for the formula to work! My final answer with this fix, the escape velocity of Saturn is 35.546 km per sec. Thanks everyone!

G= 6.67x10^-11 M= 568.3x10^24 Kg R= 60000 Km

I've been using the formula: Ve= the square root of 2GM/R I've been comparing my answer to Nasa's data tables on the planets.

Hey guys and girls. I've been trying to calculate Saturn's Escape Velocity but my answer is coming out way to high. Could someone demonstrate how I would go about finding Saturn's Escape Velocity?

I found the problem, I was acting as though I am a celestial body! Haha. Thank you all for the help!

I am working on a problem to sate my own curiosity. :) My mass is approximately 85.1 Kg. The Earth's mass is approximately (5.972x10^24 kg) and the distance between our center of masses is roughly the same as the Earth's radius of (6371 km) so I was wondering; what would the Earth's...
