2021-05-21 15:48:12 Are there white holes in the universe?

A white hole is a hypothetical region of space-time.

A white hole has mass. It might spin. A ring of dust and gas could gather around the event horizon — the bubble boundary separating the object from the rest of the universe. But a white hole blasts material out into space, instead of pulling material inward.

Basically, a white whole is the reverse of a black hole.

White holes are now completely theoretical mathematical concepts. Although there are physicists out there who think white holes might be more than theoretical.

According to specialists in loop quantum gravity, a black hole singularity could compress down until the smallest possible size. Then it would rebound as a white hole.

Another theory suggests that white holes might explain the Big Bang since this is another situation where a tremendous amount of matter and energy spontaneously appeared.

Could a white hole give birth to our Universe?

2021-05-18 13:36:27 There is no sound in space, due to the absence of air. Is there a way to experience total quietness on Earth?

The quietest place on the planet is an anechoic chamber at Orfield Laboratories in Minnesota.

Inside the room it's silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA. Steven Orfield, the lab's founder said: “We challenge people to sit in the chamber in the dark – one person stayed in there for 45 minutes. When it’s quiet, ears will adapt. The quieter the room, the more things you hear. You’ll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. In the anechoic chamber, you become the sound."

But the room isn't just for entertaining people. Companies test their products in it to find out just how loud they are. And NASA has sent astronauts there to help them adapt to the silence of space.

One of the materials for the radiation shield would be water, but it can’t be used as a primary structure for the spacecraft. Another is polyethylene: it is fairly cheap to produce, but it’s not strong enough to build a large structure.
There are BNNTs — tiny nanotubes made of carbon, boron, and nitrogen, with hydrogen — flexible enough to be used as a structure for the spacesuits and spacecraft.
Scientists are also investigating an opportunity to create so-called force fields, bubbles protecting space habitats or spacecrafts from radiation as Earth’s magnetic field does.

2021-05-17 12:48:57 Space radiation is different from what we experience on Earth. It is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light – eventually, only the nucleus of the atom remains.
Our biggest source of radiation is the Sun. Energetic particles can be dangerous to humans because they pass right through the skin, depositing energy and damaging cells or DNA along the way.
Fortunately for us, Earth’s huge magnetic bubble, called the magnetosphere, deflects the vast majority of these particles and protects our planet. And our atmosphere absorbs the majority of particles that do make it through the magnetosphere.
However, beyond Low Earth Orbit, space radiation may place astronauts at significant risk for radiation sickness, and increased lifetime risk for cancer, central nervous system effects, and degenerative diseases... Open / Comment

2021-05-11 15:06:11 This 3D-printed Mars habitat could be a home for future colonists.
AI SpaceFactory, a “multi-planetary architectural and technology design agency” in New York City, designed this egg-shaped habitat called “Marsha”. It was a winning design of the 3D-Printed Habitat Challenge held by NASA— a competition to create sustainable shelters suitable for the Moon, Mars, or beyond using resources available on-site in these locations.
Marsha is designed to be 3D-printed using a mixture of ground-up Martian rocks and plant-based polymer.
The habitats have four levels inside, connected by spiral staircases.
A ground-floor level would include a sealed hatch for entering and exiting the pod in space suits, as well as laboratories for astronauts to conduct tests and other work. Other levels would include a kitchen, a garden, a level for exercising and recreational activities, and four “sleepy pods” — private living quarters with a bed and desk.

2021-05-08 13:18:48 ...Ideas of creating special spacecraft for waste disposal are also being considered, but such devices should be monitored constantly and controlled precisely, otherwise, the device itself risks becoming a piece of space debris.
Until the solutions are implemented worldwide, humanity should focus on preventing further pollution of near-Earth space.
Asgardia stands for the initiative: specialists from around the globe have been sharing solutions during congresses held by Asgardia, representatives of the First Space Nation are not only raising awareness but also collaborate with international space organizations.

2021-05-08 13:18:16 How humanity is going to get rid of space debris?
The historic launch of the Sputnik-1 spacecraft in October 1957 was a breakthrough for the whole humanity, but it also became the first-ever piece of man-made space debris in our orbit. Since then, the number of objects entering orbit has continued to grow rapidly. According to Space Situational Awareness, at the moment there may be more than 29 thousand "spent" spacecraft, upper stages of launch vehicles, and booster stages swirling around the planet.
In 2020, a record number of satellites entered orbit - 1,263 - which makes the use of near-Earth space more dangerous due to the threat of a collision of operating spacecraft with man-made debris.
At the moment, different methods of solving the problem are being considered. One approach involves the reuse of individual parts of launch vehicles. Others involve changes in orbits or the destruction of possibly dangerous objects of space debris... Open / Comment
