    Question Bending Space

    Hi Space forum, I am not an astro scientist or related, just some ordinary guy that love mystery hidden in our space. Pardon me if my question is too ordinary. I have too much question about space. 1. I once watched about gravity visualized video that said star bend space (visualized with a...

    Could This Be True?

    I have a question to ask people that know or understand a lot about the universe and mathematics. So the question is this: "If the reference point of light doesn't experience time due to time dilation at higher speeds, does this mean that time stops? If time would stop would this mean that...

    Dark matter or something else

    Can it not be so that the dark matter we're looking for perhaps not even exist and the bindimg/repelling force might be space itself, since black holes collide and gravitational waves are generated, and the speed at which those waves travel can't surpass that of light, so it may be that those...

    Question Probes to interstellar space

    What is preventing us from sending numerous tiny probes/orbiters into interstellar space, do we still lack the technology or courage? Since through gravity assist alone we can increase the speed of spacecrafts, why don't we send out many in various directions, with all the necessary instruments...

    Why is garbage in space dangerous?

    The clogging of near-Earth space could lead to the "Kessler effect" - a situation where space travel is not possible, as NASA experts warned earlier this year. Donald Kessler, an analyst at the National Aeronautics and Space Administration, predicted back in 1978 that space debris would...

    Question what intrigues you about space

    What makes you love space, the universe, and the ideas of other planets and life? I'll start off. I've always liked space since I was a kid and I had stickers of the solar system on my bedroom wall. Now, still basically a kid, I'm more obsessed with space than I've ever been. No matter what...

    Is it possible for us to discover habitable planets close to us?

    I’m a writer and currently writing a book that involves space travel to a potentially habitable planet. I’ve done lots of research of potentially habitable planets that we are already aware of and I am aware that scientists believe there to be billions of planets in the Milky Way alone. What...

    What would gravity feel like on a hollow earth?

    If you had 2 earths, one original and the other hollow with a 1m thick crust but with identical mass and dimensions as our earth. Would you experience gravity identically on the outer surface of both? Also, what would you feel if you stood on the inside surface of the hollow earth? If you stood...

    Do any of you know anything about comet NEOWISE (2020 F3)? says it could reach 2nd magnitude in July and Wikipedia says that it will reach perihelion on July 3rd and expected to be visible to the naked eye. Besides that and the page, I can't find anything else.

    twin body theory

    every celestial body, it is said, is part of a 2 or twin body system which revolve around a common centre of gravity, which sometimes lay inside one of the 2 such celestial bodies (because one is bigger than the other) so it looks as if the other is revolving around this ... is this theory...

    What Are Wormholes? Could We Really Travel Through Them?

    The human curiosity is one such element of the psyche that simply can never be quenched, especially when it comes to space travel. Did you know that the annual funding of the Earth Science program worldwide totals up to a meager $11.6 billion? Compare it with the budget of global space...
