Gravitational Wave Propulsion đŸ€” — check the abstract.


This paper sums up aftereffects of past examinations, including proposed models, so as to construct an advanced hypothetical structure for Gravitational Wave Propulsion.

High effectiveness generators depend on cognizant sources, for example synchronized MEMS oscillators, the HTSC Gaser, in light of cognizant turn 2 changes in s-wave/d-wave super conductors, and the atomic electromagnetic wave to gravitational wave up-changing over transducer, in view of dineutrons. After gravitational wave age is effectively demonstrated in the research center, it will be pos-sible to apply an idea created in the field of cosmology. It was discovered that the back-ground vitality thick ness may offer mass to the graviton, which thus may permit gravi tons to produce push. Nearby foundation vitality thickness can be expanded by accusing materials of high dielectric steady in close ness to the wave producing components. Centered Gravitational Waves may likewise create singularities, where the radiation is changed over into a coulomb-like gravitational field. Gravitation al singularities will set a n-body floating framework among them selves, the rocket, and the rest of the assortments of the universe, with clear propulsive impacts.

How to Invest in Space Exploration

Posted by in categories: business, economics, space travel

Space exploration may long have been the domain of national governments due to the huge budgets required. Investment from the private sector was slow to pick up due to uncertain economic returns and the concern that their involvement will in some way downplay the virtues of science. However, recent developments have seen increased participation by the private sector, ranging from partnerships with federal space programs to commercial space flights. As an investor, determine whether there is value to be unlocked from your support of space exploration activities, the feasibility of making a consistent return on investment and your capacity for risk.

You do not need to be a billionaire to invest in outer space. Several exchange-traded funds invest in aerospace companies likely to be involved in space exploration technology and related equipment. You can opt to buy stock in individual aerospace firms after diligent research to find firms that have the best track record. Investing in space ventures directly is too risky, and you have to be experienced and knowledgeable about the respective companies’ technology, management and business plans. In addition, their stocks are likely to plummet hard after setbacks or major disasters, so getting a diversified fund spreads the risk.

You can choose to invest your money in mutual funds with diversified holdings in aerospace companies. The mutual fund will be a collection of stocks, bonds and other securities. Your investment will yield money from dividends, distribution if the fund makes capital gains, or by selling your portfolio if the fund’s shares increase in price. Choose an investment that is low risk if you are new to the investment world or the space technology industry.

“Holy Grail” –Proof of Cosmic Objects Without a Hard Surface Confined Within an Invisible Boundary

Posted by in categories: cosmology, physics

O,.o.


Albert Einstein described black holes as strange objects “where God divided by zero.” An international team of astrophysicists has now confirmed that black holes are a distinct “species” from neutron stars –comparable to black holes in mass and size but confined within a hard surface, unlike black holes, an exotic cosmic object without a hard surface predicted by Einstein’s theory of General Relativity that do not have a surface, and are confined within an invisible boundary, called an event horizon, from within which nothing, not even light, can escape.

This AI Generates Photos Using Only Text Captions as a Guide

Posted by in categories: information science, robotics/AI

Researchers at the Allen Institute for Artificial Intelligence (AI2) have created a machine learning algorithm that can produce images using only text captions as its guide. The results are somewhat terrifying
 but if you can look past the nightmare fuel, this creation represents an important step forward in the study of AI and imaging.

Unlike some of the genuinely mind-blowing machine learning algorithms we’ve shared in the past—see here, here, and here —this creation is more of a proof-of-concept experiment. The idea was to take a well-established computer vision model that can caption photos based on what it “sees” in the image, and reverse it: producing an AI that can generate images from captions, instead of the other way around.

This is a fascinating area of study and, as MIT Technology Review points out, it shows in real terms how limited these computer vision algorithms really are. While even a small child can do both of these things readily—describe an image in words, or conjure a mental picture of an image based on those words—when the Allen Institute researchers tried to generate a photo from a text caption using a model called LXMERT, it generated nonsense in return.

Large Genetic Analysis Newly Links 5 Genes to Sporadic ALS

Posted by in category: genetics

A combined analysis using people of Japanese, Chinese, and European ancestry identified five new genes associated with the non-familial, sporadic form of amyotrophic lateral sclerosis (ALS).

These findings further an understanding of the genetic basis of sporadic ALS, and may support the development of new therapies.

Comet 67P/Churyumov-Gerasimenko Has A Tiny Moon

Posted by in categories: particle physics, space

Comet 67P/C-G is a dusty object. As it neared its closest approach to the Sun in late July and August 2015, instruments on Rosetta recorded a huge amount of dust enshrouding the comet.

This is tied to the comet’s proximity to our parent star, its heat causing the comet’s nucleus to release gases into space, lifting the dust along. Spectacular jets were also observed, blasting more dust away from the comet. This disturbed, ejected material forms the ‘coma’, the gaseous envelope encasing the comet’s nucleus, and can create a beautiful and distinctive tail.

A single image from Rosetta’s OSIRIS instrument can contain hundreds of dust particles and grains surrounding the 4 km-wide comet nucleus. Sometimes, even larger chunks of material left the surface of 67P/C-G — as shown here.

Starlink puts towns devastated by wildfires online for disaster relief workers

Posted by in categories: Elon Musk, internet, satellites

SpaceX’s Starlink has showed its utility in connecting far-flung locations to the internet quickly and relatively simply in Washington, where like much of the west coast wildfires have caused enormous damage to rural areas. A couple small towns in the state have received Starlink connections to help locals and emergency workers.

The town of Malden was almost completely destroyed, but restoration efforts are underway, and of course it helps to be able to access the internet for communicating with residents and authorities. With power and cellular service unreliable, satellite internet is a good temporary option, and Starlink stepped up.

As SpaceX founder Elon Musk said on Twitter, the company is prioritizing emergency responders and areas without internet:

No bones about it: Wild gorillas don’t develop osteoporosis like their human cousins

Posted by in categories: biotech/medical, life extension

In a study of gorilla skeletons collected in the wild, Johns Hopkins Medicine researchers and their international collaborators report that aging female gorillas do not experience the accelerated bone loss associated with the bone-weakening condition called osteoporosis, as their human counterparts often do. The findings, they say, could offer clues as to how humans evolved with age-related diseases.

The study was published on Sept. 21, 2020, in Philosophical Translations of the Royal Society B.

“Osteoporosis in humans is a really interesting mechanical problem,” says Christopher Ruff, Ph.D., professor at the Center for Functional Anatomy and Evolution at the Johns Hopkins University School of Medicine. “In terms of natural selection, there is no evolutionary advantage in developing with aging to the point of a potential fracture. By looking at close relatives of humans on the evolutionary tree, we can infer more about the origins of this condition.”

Mutations that affect aging: More common than we thought?

Posted by in categories: biological, evolution, life extension

The number of mutations that can contribute to aging may be significantly higher than previously believed, according to new research on fruit flies. The study by scientists at Linköping University, Sweden, supports a new theory about the type of mutation that can lie behind aging. The results have been published in BMC Biology.

We live, we age and we die. Many functions of our bodies deteriorate slowly but surely as we age, and eventually an organism dies. This thought may not be very encouraging, but most of us have probably accepted that this is the fate of all living creatures—death is part of life. However, those who study find it far from clear why this is the case.

“The evolution of aging is, in a manner of speaking, a paradox. Evolution causes continuous adaptation in organisms, but even so it has not resulted in them ceasing to age,” says Urban Friberg, senior lecturer in the Department of Physics, Chemistry and Biology at Linköping University and leader of the study.
