Did You Know ?
1. The Startup That Sells Sunlight
- I know you have heard many Startups but,
- A startup called Reflect Orbital has a unique idea.
- They plan to sell sunlight.
- How it works:
- They may put a mirror in space
- This mirror can reflect sunlight to Earth
- It can do this 24 hours a day, 7 days a week
- This idea could help solar farms:
- Solar panels could work all day and night
- This would create uninterrupted electricity
- The technology has other uses too:
- It could change advertising
- Companies could make ads in the sky
- These ads would be visible to many people
- This is a new type of B2B solar service.
- It's an example of innovative startup ideas.
- This technology combines space and energy industries.
- It shows how startups can think of surprising solutions.
- The idea could change how we use solar power.
- It's a futuristic approach to energy and advertising.
2. Can Cryogenics Preserve the Human Body for Centuries
- Scientists have studied what happens when you freeze a body at -196°C.
- At this temperature:
- Molecular processes slow down by 99%
- Almost all biological activity stops
- This is the idea behind cryogenic preservation.
- Current status:
- About 500 bodies have been frozen this way
- People agree to this before they die
- Companies that do this freezing:
- Alcor Life Extension Foundation
- KrioRus
- Tomorrow Biostasis GmbH
- Oregon Brain Preservation
- The goal is to revive these frozen bodies in the future.
- People hope to be brought back to life still young.
- But even at very cold temperatures:
- Molecular activity doesn't completely stop
- This is a form of attempted life extension.
- It's based on slowing down body processes with extreme cold.
- The science is still uncertain about reviving frozen bodies.
3. The Controversial Human-Pig Hybrid
- The scientists keep the process of hybrid geo continuing 24/7.
- So far, several scientists have been working in hybrid geo.
- Scientists are also studying human-pig hybrids.
- This research sometimes became controversial.
- Pig organs are already used in some human transplants:
- For example, pig heart valves
- Pigs are good for this research because:
- Their organs are similar in size to human organs
- They have a short reproductive cycle
- These factors make pigs ideal for organ farming.
- Pig organs usually work well in humans:
- They don't often cause bad reactions
- This makes pig organs promising for transplants.
- It's an important development in medical science.
- This research could help solve organ shortages.
- It's an example of a potential medical breakthrough.
- But would it be right to kill pigs and transplant their organs into humans?
- The study focuses on organ compatibility between pigs and humans.
4. The Evaporation of Black Holes
- Did you know that the dangerous object of the universe is Black Hole but
- Black holes can actually disappear over time.
- The average lifespan of a black hole is over 7 billion years.
- Black holes don't last forever:
- They slowly get smaller
- Eventually, they vanish completely
- This process is called black hole EVAPORATION (just like you boil water and after few minutes it starts evaporating) same way the Black Hole also evaporate but it will take billions of years.
- It happens because of something called Hawking Radiation:
- Named after scientist Stephen Hawking
- It causes black holes to lose mass
- How it works:
- Black holes lose a tiny bit of mass over time
- This continues for billions of years
- And then, the black hole disappears
- This shows that even black holes have an end.
- It's a surprising fact about the universe.
- Black holes are often seen as mysterious and dangerous.
- But they too have an "expiration date".
- This is one of many space mysteries scientists study.
5. Why Don't Airplanes Have Number Plates?
- Do Airplanes also have the number plates?
- Airplanes do have number plates, like cars.
- Where to find airplane "number plates":
- The answer is, on the plane's tail
- Every Airplane in this world is registered in its local government or international database
- Another fact did you know What is the total number of registered vehicles worldwide?
- Number of registered vehicles worldwide:
- About 150 crore (1.5 billion) registered cars
- About 50 crore (500 million) registered bikes
- And only about 40,000 registered commercial airplanes
- This makes airplanes very rare compared to other vehicles.
- Airplane registration is different from car registration:
- It's international
- It's more strictly controlled
- Every commercial plane has a unique identifier.
- This system helps track planes worldwide.
- It's an important part of air traffic management.
- This fact highlights differences in transportation types.
