Has time travel already been invented?
There is currently no scientific evidence or widely accepted proof that time travel has been invented. The concept of time travel remains theoretical and is still a subject of scientific research and speculation.
When will weinvent time travel?
Time travel is currently considered impossible based on our current understanding of physics, as it violates the principles of causality. While scientists continue to explore theoretical concepts like wormholes and closed timelike curves, practical time travel remains a subject of science fiction.
Will time travel be possible in 2020?
As of 2020, time travel remains a concept largely confined to science fiction and theoretical physics. While some theories, such as those involving wormholes or the effects of relativity, suggest it might be possible under certain conditions, there is currently no practical method or technology that allows for time travel. Thus, it is not feasible to travel through time in 2020 or any time soon.
What three kinds of body parts do sound waves travel through before they reach the brain?
Sound waves travel through the outer ear, then the middle ear, before reaching the inner ear where they are converted into electrical signals that travel to the brain through the auditory nerve.
How many gigawats for time travel?
There is no scientific evidence to suggest that a specific amount of gigawatts is required for time travel. Time travel is currently considered a theoretical concept and not a practical reality within the realm of physics. The idea of using a specific power level, such as "1.21 gigawatts" as shown in the movie "Back to the Future", is purely fictional.
How did people used to travel before airplanes were invented?
foot,wagon
Before the invention of the plane people used to.?
before planes were invented people used boats to travel and pigeons as messengers
What people did before the airplane was invented?
For long-distance travel, they mostly used trains and passenger ships.
Is traveling in a hot airballoon a practical way to travel?
No.
Robert fulton invented the first practical what?
Robert Fulton invented the first practical steamboat, known as the Clermont, which successfully navigated the waters of the Hudson River in 1807. This innovation demonstrated the viability of steam-powered vessels for commercial transportation, revolutionizing travel and trade on rivers and later on oceans. Fulton's work helped pave the way for the widespread use of steam power in transportation.
How did people travel before railways are invented?
Horse-drawn wagons and carts, or on horseback, or on foot. Boats were another option of course.
How did humans travel before wheel was invented?
By foot for sure, on horseback/donkeyback perhaps?
What did people do before airplanes were invented?
Before airplanes were invented, people relied on various forms of transportation for long-distance travel, including trains, ships, and horse-drawn carriages. The advent of steamships and railroads in the 19th century significantly accelerated travel times across continents. Additionally, hot air balloons and airships were experimented with for aerial travel, albeit with limited success and safety. Overall, travel was generally slower and more labor-intensive compared to modern air travel.
Why was the steamtrain invented?
to travel
How would people travel before cars were invented?
They traveled by walking, horses, buggies, bulls, donkeys, or any animal they could ride.
Why are cars invented?
they are invented so people can travel around easier
Who invented travel?
Thomas Cook
