Does space go on forever? Many think it’s likely you would just keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end. … Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Then, Is it possible to go back in time?
Time travel is theoretically possible, new calculations show. … Time travel is possible based on the laws of physics, according to new calculations from researchers at the University of Queensland. But time-travelers wouldn’t be able to alter the past in a measurable way, they say — the future would stay the same.
Secondly, How long is 1 hour in space? Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.
Who created space?
The modern concept of outer space is based on the “Big Bang” cosmology, first proposed in 1931 by the Belgian physicist Georges Lemaître. This theory holds that the universe originated from a very dense form that has since undergone continuous expansion.
Will space and time end?
According to Einstein’s General Relativity, which is our best current description of space and time, the only place where time – and also space – ends is in a so-called singularity. This involves gravitational forces becoming so intense that space and time lose all meaning.
Can we create a time machine?
Travelling in time might sound like a flight of fancy, but some physicists think it might really be possible. BBC Horizon looked at some of the most promising ideas for turning this staple of science fiction into reality.
Who invented time machine in world?
The idea of a time machine was popularized by H. G. Wells’ 1895 novel The Time Machine. It is uncertain if time travel to the past is physically possible.
How do I become a time traveler?
How to become a full-time traveler? 5 ways to make it happen

- Conclusion.
Do you age slower in space?
We all measure our experience in space-time differently. That’s because space-time isn’t flat — it’s curved, and it can be warped by matter and energy. … And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.
Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
Is there dead bodies in space?
Remains are generally not scattered in space so as not to contribute to space debris. Remains are sealed until the spacecraft burns up upon re-entry into the Earth’s atmosphere or they reach their extraterrestrial destinations.
What existed before the universe?
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
Can you light a fire in space?
Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.
What happens if a planet gets bigger?
As the planet grows in size, its mass and therefore gravity increases, allowing it to capture not only the accumulated dust and rocks, but also the gas, which forms an atmosphere.
Where does the earth end?
According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth’s surface.
Is time an illusion?
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. … He posits that reality is just a complex network of events onto which we project sequences of past, present and future.
Who invented time machine in India?
According to our Mocktale sources, well-known scientist Sheshadri Cooperama has invented a time machine that would enable the leading aviation experts to travel back in time and bring a copy of the guidelines laid by Hindu sage Maharishi Bharadwaj.
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. …
Do black holes exist?
Black holes of stellar mass form when very massive stars collapse at the end of their life cycle. After a black hole has formed, it can continue to grow by absorbing mass from its surroundings. … There is consensus that supermassive black holes exist in the centers of most galaxies.
Who is the first time traveler?
Did you know that Russian Cosmonaut Сергей Авдеев (“Sergei Avdeyev”) is considered Earth’s first significant time traveler? During his active years as a cosmonaut (1992-1999), he set a record for cumulative time in space.
What are the rules in Back to the Future?
Rules:
- You can travel to a specific date and time, but not space;
- If your flux thingy breaks, you’ll need to find some lightning or other source of 1.21 gigawatts of power;
- Don’t ever bump into your past self, it’ll cause problems;
- The timeline can be altered, but you’ll travel back to an alternate present/future;
How do you survive time travel?

Can you get pregnant in outer space?
As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.
