Can A Slow Shuttle Leave A Fast Ship Safely?

“I am traveling in a Generational spaceship that has, over time, been accelerated to 0.4 light speed. The ship can not slow down until it nears its destination in 50 years. The ship has a small, conventionally powered shuttle craft whose top speed is 0.1 light speed. Can that shuttle leave the ship and maneuver about the ship without being left behind? I am thinking that when it leaves the ship it is moving at…

Why Didn’t ‘Oumuamua Hit The Sun?

“If Oumuamua has come from so far away, and in it’s final approach was primarily attracted by the Sun, why didn’t it hit the Sun? Were the gravitational forces of other planets sufficient to make it miss?”The answer to this question lies in how gravity acts over large distances, with a bit of interstellar aiming thrown in for flavor.On the surface of planet Earth, the force of gravity is pretty much a constant through our…

What Would Have Happened To That Interstellar Object If It Had Hit The Sun?

“What would have happened if A/2017 U1 had hit or grazed the sun? Would we have noticed?”The snappily-named object A/2017 U1 may be more familiar to you as the interstellar visitor that zipped through our solar system at nearly 16 miles per second, discovered in mid-October.

Can You Make An Object Pretend It Has Less Mass Than It Does?

“Speed can make objects act as if they have more mass, but can you ever make an object appear to have less mass?”It’s true that speeding an object up to considerable fractions of the speed of light will make things behave like they are more massive than they do when they’re moving at slower, more human, speeds. But going the other direction is not…Read the full article on Forbes!Remember to vote for Astroquizzical, which has…

How Do We Track Photons Through Space?

“When a particle moves through spacetime, how do we know it is the same particle and not some excitation that is passed from place to place?”We don’t! This is a really interesting feature of our universe, and it comes from the observation that all subatomic particles are described by a few key properties, but are otherwise completely and utterly…Read the full article on Forbes!Remember to vote for Astroquizzical, which has been nominated for Canada’s top…

“Can a star reverse its rotational direction during some time in their life, and if so, how would it affect any planets around it?”The stars in the night sky all have their preferred direction of rotation, which depends directly on the exact way that the cloud of gas and dust that the star formed out of collapsed. If there was slightly more …Read the full article on Forbes! Remember to vote for Astroquizzical, which has been…
