lol 98 million? why not something proportional to the ad revenue that apple made in said years? oh I know why because law exists for billionaires.
- Comment on Apple CEO Tim Cook Donating $1 Million to Trump's Inaugural Fund 3 weeks ago:
he is ultra rich, the hateful divide and conquer tactics applied to common people don’t apply to him so he simply does not have any empathy for the matter.

Achieving a velocity of 0.5 times the speed of light (ccc) for space travel involves solving advanced challenges in physics and engineering. The Python script below creates a simplified optimization framework to analyze the propulsion needed. It uses physics principles like relativistic mass-energy equivalence and propulsion mechanisms such as fusion or antimatter engines.
This code assumes you have the theoretical fuel and energy to achieve the speed, but it abstracts away complex challenges like time dilation, cosmic radiation, and material limitations.
Python Code ’’’ import numpy as np import matplotlib.pyplot as plt
Constants
c = 3e8 # Speed of light (m/s) target_speed = 0.5 * c # Target speed (0.5c) ship_mass = 1e5 # Mass of the spacecraft without fuel (kg) fuel_efficiency = 1e-3 # Fuel conversion efficiency (e.g., antimatter ~0.1, fusion ~0.001) exhaust_velocity = 1e7 # Exhaust velocity of the propulsion system (m/s) specific_impulse = exhaust_velocity / 9.81 # Specific impulse (seconds)
Functions
def relativistic_mass(speed, rest_mass): “”“Calculate relativistic mass.”“” gamma = 1 / np.sqrt(1 - (speed / c) ** 2) return gamma * rest_mass
def fuel_needed(final_speed, ship_mass, exhaust_velocity): “”“Estimate fuel required using the Tsiolkovsky rocket equation.”“” delta_v = final_speed mass_ratio = np.exp(delta_v / exhaust_velocity) fuel_mass = ship_mass * (mass_ratio - 1) return fuel_mass
Optimization
def optimize_propulsion(target_speed, ship_mass, exhaust_velocity, fuel_efficiency): fuel_mass = fuel_needed(target_speed, ship_mass, exhaust_velocity) energy_required = fuel_mass * fuel_efficiency * c**2 # Total energy for propulsion return fuel_mass, energy_required
Perform calculations
fuel_mass, energy_required = optimize_propulsion(target_speed, ship_mass, exhaust_velocity, fuel_efficiency)
Display results
print(f"Target speed: {target_speed / c:.2f}c") print(f"Required fuel mass: {fuel_mass:.2e} kg") print(f"Energy required: {energy_required:.2e} joules")
Visualization
speeds = np.linspace(0, 0.5 * c, 100) fuel_masses = [fuel_needed(speed, ship_mass, exhaust_velocity) for speed in speeds]
plt.figure(figsize=(10, 6)) plt.plot(speeds / c, fuel_masses, label=‘Fuel Mass Required’) plt.xlabel(‘Speed as a Fraction of Light Speed (v/c)’) plt.ylabel(‘Fuel Mass (kg)’) plt.title(‘Fuel Requirement vs. Speed’) plt.legend() plt.grid() plt.show() ’’’
How it Works:
Relativistic Mass: Accounts for relativistic effects as the spacecraft approaches significant fractions of the speed of light. Tsiolkovsky Rocket Equation: Estimates fuel requirements based on the propulsion system's exhaust velocity and initial mass. Energy Requirement: Evaluates energy needs assuming the specified fuel efficiency.
Limitations:
Idealized Assumptions: Assumes perfect efficiency and ignores engineering constraints. Simplified Physics: Doesn't account for external factors like gravity, drag, or realistic propulsion systems. Energy Storage: No consideration for how energy would be stored or delivered.

- Comment on BBC staffers reveal editor's 'entire job' to whitewash Israeli war crimes 4 weeks ago:
for me passive participation is turning a blind eye and not even criticizing. when you start withholding information in an attempt to whitewash genocide and appease the genociders then you are actively participating.

well this is even worse than pretending like nothing is happening. this is active participation.

They don’t have a plan. Looking at examples like the “submarine” guy will tell you everything you need to know. The guy literally dived to his own death taking his son with him because he thought submarine quality requirements were overrated.

Crazy how if it was any democrat saying drink raw milk s/he would likely be accused of a conspiracy in which he is trying to spread bird flu so they can have another pandemic and vaccine manufacturers make money out of it. But when a republican says it, s/he is probably celebrated for using the wisdom of our grand grand parents.
