Who Found The Light Year? In 1838, the German astronomer Friedrich Wilhelm Bessel (and not the Scottish astronomer Thomas Henderson, as is often mentioned) was the first to use the light-year as a unit of measurement in astronomy. He measured the distance separating us from the binary star 61 Cygni as 10.3 light-years. What is
Can A Time Machine Be Invented? Time travel may soon be possible, according to an astrophysicist who believes he’s worked out a way to build a time machine. Professor Ron Mallett from the University of Connecticut in the US claims to have written a scientific equation that could be used to create a device that
Why Can T We Travel To Other Galaxies? Intergalactic travel is the hypothetical crewed or uncrewed travel between galaxies. Due to the enormous distances between the Milky Way and even its closest neighbors—tens of thousands to millions of light-years—any such venture would be far more technologically demanding than even interstellar travel. Why we may never
Will Space Travel Ever Be Possible Quora? Yes. Due to the ever-present population expansion, one-way tickets will be free. Can humans survive interstellar travel? the fact that there’s no way to decelerate once you make it to your destination, since there’s no on-board fuel, and even if you could scale it up to transport humans,
Is Earth Part Of The Sagittarius Dwarf Galaxy? Brace yourself for a shock, bring out those handkerchiefs while wailing violins build to a crescendo around you: The earth is actually part of a formation called the Sagittarius Dwarf galaxy; an entity so small — in the larger scheme of the cosmos — that it got
Should Humans Explore Outer Space? Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations. Why we shouldn’t explore
Will Humans Ever Achieve Interstellar Travel? The truth is that interstellar travel and exploration is technically possible. There’s no law of physics that outright forbids it. But that doesn’t necessarily make it easy, and it certainly doesn’t mean we’ll achieve it in our lifetimes, let alone this century. Can humans survive interstellar travel? the fact
Will Faster Than Light Travel Ever Be Possible? In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light. What will happen if
Which Of The Suggested Methods For Interstellar Travel Do You Find Most Plausible And Why? When it comes to interstellar travel, the best approach may be a laser-pushed light sail. First proposed by Robert Forward in a 1984 paper, this is just like a solar sail that is pushed along by light – but it
What Would Happen If Earth Went Into A Black Hole? Our atmosphere would start to be vacuumed up. And then huge chunks of the Earth would rip apart and follow suit. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth
