What shape is space?


Everything we think we know about the shape of the universe could be wrong. Instead of being flat like a bedsheet, our universe may be curved, like a massive, inflated balloon, according to a new study.

That's the upshot of a new paper published today (Nov. 4) in the journal Nature Astronomy, which looks at data from the cosmic microwave background (CMB), the faint echo of the Big Bang. But not everyone is convinced; the new findings, based on data released in 2018, contradict both years of conventional wisdom and another recent study based on that same CMB data set.

space is infinite, gravitational forces warp space.

College Students Hatch Nuclear-Powered Magnetic Plan to Protect Marsonauts from Cosmic Rays

The voyage to Mars will expose astronauts to deadly levels of cosmic radiation. But a group of college students has a plan to shield spacecraft from radiation.(Image: © NASA/Viking 1)
DENVER — A group of undergrad students is developing a magnetic shield to defend interplanetary astronauts from the intense cosmic radiation between Earth and Mars.

The students, from Drake University in Iowa, presented their project in the poster session Saturday (April 13) at the April meeting of the American Physical Society. Their MISSFIT (Magneto-Ionization Spacecraft Shield for Interplanetary Travel) design uses a powerful magnetic shield that, like Earth's magnetosphere, protects the planet from high-energy particles. The defense system also incorporates "passive" shielding to mimic the ionosphere — Earth's second layer of defense. [When Space Attacks: The 6 Craziest Meteor Impacts]

With help from a small NASA grant through the Iowa Space Grant Consortium, experiments are already underway on the passive shielding, which could protect astronauts from high-energy gamma-rays that a magnetic shield can’t stop. The hope, said Lorien MacEnulty, a junior at Drake and a member of the team, is to solve a key safety problem that's delayed an eventual NASA mission to Mars: long-term exposure to interplanetary radiation.

Saving this planet is a fine quest, but if we are ever to avoid total extinction we need to populate other places

haven't achieved much? that is a significant understatement! when We can reach mach one in water (I might be impressed) then it might be time to visit mars. but there should be a colony on the moon first! and mining of the asteroid field, technically send the ore to the moon base. I think the planning is reasonable, but think a space station would be more reliable in orbit around mars. without experience Living in space I think it a bit to risky sending People to colonise Mars.

anyone know what happened to the begal. now that was an impressive piece of tech!

We have an ISS orbiting earth, why have another orbiting Mars? What would be the point of even going all that way?

We must land, and we must look at colonising and being self sufficient when there.

Small steps out into space must be taken now, it is the only way we will learn progress and advance further.

I think you have just agreed with me, mankind encounters barriers but through ingenuity works out how to overcome them.

To think that Victorians thought the speed of trains was dangerous, Adolph was concerned about the speeds of his jets and the effect on his pilots etc etc.

The speed of sound was a barrier and yet we overcame that.

As for your black holes/white holes stuff? All I can say is that our current understanding is akin to early hominids understanding of the sun the moon and the stars plus fire.

In hundreds of years from now, just as per Newton's Principia Mathematica being a useful reference book now, Einstein's theories will be the same and man's (not our) understanding of micro/macro universal matters will be far superior.

We cannot view the impossible and seemingly impassable distances from earth to other planets in other solar systems with today's understanding, future generations will look back on us as we do the victorians.

Why on earth .... or elsewhere are you posting it again?

If you believe in the theory of evolution then that theory surely starts to break down when you start adding intelligent design and purpose to the mix because that's exactly what that guy there just did.

Where no one has gone before

At the heart of Davis' paper is the principle — supported by rigorous scientific theory — that faster-than-light travel is a real and even tangible possibility. The last section of the paper proposes nine "next steps" that would push the field toward engineering prototypes and other practical tests of faster-than-light theories.

These steps include creating computer simulations to model the structure and effects of space warps. Davis also calls for more rigorous exploration of the Ford-Svaiter mirror, which is still a largely theoretical device. The mirror is just one possible way to generate negative energy; further study is needed to determine whether there are any other practical methods of achieving the same effect. [See also: Hypersonic 'SpaceLiner' Aims to Fly Passengers in 2050]

Davis describes the development and implementation of space-warp travel as "technically daunting" in his paper, but in conversation, he said he has no doubt that faster-than-light travel will someday be not only possible, but necessary.

"The Earth is subjected to natural and outer space and ecological disasters, so life is too fragile, while the planets in the solar system are not very hospitable to human life. So we need to explore extrasolar planets for alternative homes," Davis said.

"This is all part of the growth and evolution of the human race."
